    What Is Prorated Rent?

    Prorated rent is a partial month's rent calculated when a tenant moves in or out on any day other than the first or last of the month. Instead of paying a full month, you pay only for the days you actually occupy the unit.

    The Formula
    Monthly Rent ÷ Days in Month × Days Occupied
    Move-In Example
    $1,500 rent, move in day 15 of 30: $1,500 ÷ 30 × 16 = $800
    Move-Out Example
    $1,800 rent, move out day 10 of 31: $1,800 ÷ 31 × 10 = $580.65

    Most landlords use the daily rate method (rent ÷ actual days in month). Some leases use a 30-day method (rent ÷ 30) or annual method (annual rent ÷ 365). Our calculator supports all three - select your method above for an instant result.

    How to Calculate Prorated Rent: Step-by-Step (2026)

    To calculate prorated rent, use the daily rate method - the standard used by most landlords and courts in all 50 states:

    1. 1

      Find the daily rent rate

      Divide monthly rent by the actual number of days in the move-in or move-out month.

      Daily Rate = Monthly Rent ÷ Days in Month

    2. 2

      Count the days occupied

      For move-in: days from move-in date through the last day of the month (inclusive). For move-out: days from the 1st through move-out date.

    3. 3

      Multiply to get your prorated amount

      Prorated Rent = Daily Rate × Days Occupied

    Move-In Example (June 15, $1,500/mo)

    $1,500 ÷ 30 days = $50/day

    Days occupied: June 15-30 = 16 days

    Prorated Rent = $50 × 16 = $800

    Move-Out Example (Oct 10, $1,800/mo)

    $1,800 ÷ 31 days = $58.06/day

    Days occupied: Oct 1-10 = 10 days

    Prorated Rent = $58.06 × 10 = $580.65

    The calculator above handles all three methods automatically. Use it to skip the math and get your exact prorated amount in seconds.

    What is Prorated Rent?

    Prorated rent is the proportional amount you pay when renting a property for only part of a calendar month, rather than the full month. Instead of paying the complete monthly rent amount, you pay only for the specific days you actually occupy the property. This fair calculation method ensures tenants don't overpay and landlords receive appropriate compensation for actual occupancy time.

    The concept of prorating applies most commonly during move-in and move-out situations. For example, if you sign a lease starting on March 15th with a monthly rent of $2,000, you wouldn't pay the full $2,000 for March. Instead, you'd calculate your rent for just the 17 days you occupy the property that month (March 15-31). Using the standard daily rate method, this would equal approximately $1,097 for that partial first month.

    Common Situations Requiring Prorated Rent

    Moving In Mid-Month

    When your lease start date falls in the middle of a month, you only pay for the days from your move-in date through the end of that month. The following month, you begin paying full monthly rent on the 1st.

    Moving Out Early

    If you vacate the property before the end of your lease month and give proper notice, you typically only pay rent through your actual move-out date, not the entire month. This protects tenants from paying for days they don't occupy the unit.

    Lease Terminations

    When a lease ends mid-month by mutual agreement, eviction, or early termination with landlord approval, prorated rent ensures both parties are treated fairly for the partial month of occupancy.

    Short-Term Rentals

    Month-to-month leases or temporary housing arrangements frequently involve prorated calculations when rental periods don't align perfectly with calendar months.

    Why Prorated Rent Matters

    Understanding prorated rent is crucial for both tenants and landlords because it ensures financial fairness in the rental relationship. For tenants, it means you're not forced to pay for an entire month when you only occupy the property for a few days. This can save hundreds of dollars during move-in and move-out transitions. For landlords, proper proration helps attract quality tenants by demonstrating transparent, ethical business practices while still ensuring they receive appropriate compensation for the days the property is occupied.

    The financial impact can be significant. Consider a scenario where you move into a $2,500/month apartment on the 25th of a 30-day month. Without proration, you'd pay the full $2,500 for only 6 days of occupancy - an effective daily rate of over $416! With proper proration, you'd pay only $500 for those 6 days, saving $2,000 on your first month's housing costs.

    Quick Summary: What is Prorated Rent?

    Prorated rent is the proportional amount you pay when renting for only part of a month. Instead of paying the full monthly rent, you pay only for the days you actually occupy the property.

    How to Calculate Prorated Rent: Complete Step-by-Step Guide

    Calculating prorated rent is straightforward when you follow the standard formula used by landlords and property managers across the United States. The most widely accepted method uses the actual number of days in each specific month to ensure accuracy and fairness for both tenants and landlords.

    Standard Prorated Rent Formula

    (Monthly Rent ÷ Days in Month) × Days Occupied = Prorated Rent

    This formula calculates your daily rental rate, then multiplies it by the number of days you'll occupy the property. It's the industry standard and the most accurate method available.

    Detailed Calculation Steps

    1

    Determine Your Monthly Rent

    Start with the base monthly rent amount stated in your lease agreement. This is typically the amount you would pay for a full calendar month of occupancy.

    Example: Your lease states monthly rent of $1,800

    2

    Count the Total Days in the Month

    Use the actual number of days in the specific month you're calculating. Never use a fixed 30-day month, as this creates inaccuracies.

    January, March, May, July, August, October, December: 31 days
    April, June, September, November: 30 days
    February: 28 days (29 in leap years)
    3

    Calculate Your Daily Rental Rate

    Divide your monthly rent by the number of days in that month. This gives you the cost per day of occupancy.

    Formula: Daily Rate = Monthly Rent ÷ Days in Month

    Example: $1,800 ÷ 30 days = $60.00 per day

    4

    Count Your Occupied Days

    Determine how many days you'll occupy the property during the partial month. Include both your move-in and move-out dates in the count.

    Multiply to Get Your Prorated Amount

    Take your daily rate and multiply it by the number of days you'll occupy the property. This final number is your prorated rent.

    Formula: Prorated Rent = Daily Rate × Days Occupied

    Example: $60.00 × 15 days = $900.00

    Final Prorated Rent: $900.00

    Complete Real-World Example

    Scenario: Moving Into a New Apartment

    Situation: You're moving into a new apartment on October 18th. Your lease states the monthly rent is $2,400.

    Calculation Breakdown:

    Monthly Rent:$2,400
    Days in October:31 days
    Move-in Date:October 18th
    Days Occupied:14 days (Oct 18-31)
    Daily Rate Calculation:$2,400 ÷ 31 = $77.42/day
    Prorated Calculation:$77.42 × 14 days = $1,083.88
    Your First Month's Rent:$1,083.88

    Alternative Calculation Methods

    While the daily rate method (dividing by actual days in the month) is the recommended standard, you may encounter alternative approaches in older lease agreements or specific jurisdictions:

    Recommended

    Actual Days Method

    Uses real calendar days (28-31)

    (Rent ÷ Actual Days) × Days Occupied
    Older Leases

    30-Day Month Method

    Always divides by 30 days

    (Rent ÷ 30) × Days Occupied

    Based on yearly rent

    ((Rent × 12) ÷ 365) × Days

    Move-In vs Move-Out Prorated Rent: Key Differences Explained

    Whether you need a prorated rent calculator for move-in or a prorated rent calculator for move-out, the underlying formula is the same - but the way you count occupied days differs. Understanding these differences ensures you pay (or charge) the correct amount during lease transitions.

    Move-In
    Prorated Rent Calculator: Move-In

    Use this when starting a lease mid-month. Your move-in prorated rent covers from your move-in date through the last day of that month.

    Formula:

    (Monthly Rent ÷ Days in Month) × Days from Move-In to Month End

    Example - $1,800 rent, move in March 20:

    Daily rate: $1,800 ÷ 31 = $58.06

    Days occupied: 12 (March 20-31)

    Prorated rent: $696.77

    • Paid at lease signing alongside security deposit
    • Full rent begins the following month
    • Move-in day counts as occupied
    Move-Out
    Prorated Rent Calculator: Move-Out

    Use this when ending a lease mid-month. Your move-out prorated rent covers from the 1st of the month through your last day in the unit.

    Formula:

    (Monthly Rent ÷ Days in Month) × Days from 1st to Move-Out Date

    Example - $1,800 rent, move out March 10:

    Daily rate: $1,800 ÷ 31 = $58.06

    Days occupied: 10 (March 1-10)

    Prorated rent: $580.65

    • Requires proper notice per lease terms
    • Move-out day counts as occupied
    • Security deposit returned separately

    When to Use Each Calculator Type

    Use the Move-In Prorated Rent Calculator When:

    • Signing a new lease that starts after the 1st of the month
    • Transferring to a new unit within the same complex mid-month
    • Moving from a month-to-month arrangement to a new fixed lease
    • Starting a sublease mid-month

    Use the Move-Out Prorated Rent Calculator When:

    • Your lease ends on a date other than the last day of the month
    • You and your landlord agree to early lease termination mid-month
    • You gave proper notice and your last day falls before month end
    • Calculating final rent after an eviction or court-ordered move-out

    State Laws for Prorated Rent: Legal Requirements by State

    Prorated rent requirements vary significantly across the United States. While some states have explicit laws mandating daily proration for residential leases, others leave the practice to lease agreement terms and industry custom. Understanding your state's specific regulations helps ensure you're being charged fairly and landlords are meeting their legal obligations.

    States with Mandatory Proration Laws

    Required

    California

    California Civil Code Section 1947 explicitly requires landlords to prorate rent based on the actual number of days in each month. This is the strictest prorated rent law in the country. Landlords must calculate daily rates using actual calendar days (never 30-day months), and charging a full month's rent for partial occupancy is illegal.

    Legal Penalty: Tenants can recover overcharged amounts plus potential damages if landlords violate this requirement.

    Required

    New York

    While New York doesn't have a single statewide statute like California, New York City's Rent Stabilization Code and various housing court precedents effectively require daily proration for rent-stabilized apartments. Market-rate properties typically follow this practice as well, though it's usually governed by lease terms rather than explicit legal mandate.

    NYC Specific: Rent-stabilized apartments must prorate using actual calendar days in the month.

    States Where Proration is Standard Practice

    Most U.S. states don't have specific laws requiring prorated rent, but the practice has become industry standard. In these jurisdictions, proration is typically addressed in lease agreements rather than mandated by statute:

    Standard Practice
    Texas

    Texas Property Code doesn't mandate proration, but virtually all professional property managers and landlords offer it. The Texas Apartment Association's standard lease includes proration language. Refusing to prorate would make a property uncompetitive in the market.

    Standard Practice
    Florida

    Florida Statutes Chapter 83 (residential tenancies) doesn't address proration directly, leaving it to lease terms. However, the Florida Apartment Association and most landlords routinely prorate rent for competitive and ethical reasons.

    Standard Practice
    Illinois

    No state law requires proration, but Chicago's Residential Landlord Tenant Ordinance and industry practice make it nearly universal. Most lease agreements include specific proration formulas to avoid disputes.

    Standard Practice
    Washington

    Washington's Residential Landlord-Tenant Act (RCW 59.18) doesn't mandate proration, but Seattle's rental market and professional standards make it ubiquitous. Most landlords use daily rate calculations.

    What Your Lease Agreement Should Include

    Key Lease Language to Look For:

    • "Rent for partial months shall be prorated based on the number of days in that month"
    • "Daily rental rate = Monthly rent ÷ actual days in the calendar month"
    • "Move-out proration requires 30-day written notice as per state law"

    Local Ordinances May Override State Laws

    Even if your state doesn't require proration, your city or county might. Major metropolitan areas often have tenant-friendly ordinances that go beyond state requirements:

    San Francisco, CA

    Rent Ordinance requires strict proration compliance

    Chicago, IL

    RLTO specifies fair rental practices including proration

    Seattle, WA

    Tenant protection ordinances encourage proration

    Common Prorated Rent Calculation Mistakes to Avoid

    Even with a straightforward formula, prorated rent calculations can go wrong when landlords or tenants make common errors. These mistakes can result in overcharges, disputes, and damaged rental relationships. Here are the most frequent pitfalls and how to avoid them:

    Mistake #1: Using a Fixed 30-Day Month

    One of the most common errors is assuming every month has 30 days and dividing monthly rent by 30 regardless of the actual calendar. This creates inaccuracies that unfairly benefit either the landlord or tenant depending on the month.

    Example of the Problem:

    For $1,500/month rent in February (28 days) vs. March (31 days):

    Wrong (30-day method):

    February: $50.00/day

    March: $50.00/day

    Correct (actual days):

    February: $53.57/day

    March: $48.39/day

    Mistake #2: Not Counting Move-In or Move-Out Days

    Many people incorrectly exclude either the move-in day or move-out day from their calculation, thinking partial-day occupancy shouldn't count. However, standard industry practice and most state laws consider any day you have access to the property as a full occupied day.

    Example: Moving in on June 15th in a 30-day month

    ❌ Wrong: 15 days (June 16-30 only)

    ✓ Correct: 16 days (June 15-30 inclusive)

    Mistake #3: Ignoring Lease Agreement Terms

    Some tenants assume proration is always calculated the same way, but lease agreements may specify different methods or include clauses about notice periods, termination fees, or minimum rental periods. For example, your lease might require a 30-day notice to move out, meaning you could owe rent for days after you vacate if you didn't give proper notice.

    Mistake #4: Assuming All Charges Are Prorated

    Prorated rent typically applies only to base rent. Utilities, parking fees, storage, pet rent, and other monthly charges may not be prorated at all - or may be calculated separately. Some landlords charge full monthly amounts for these items regardless of your move-in or move-out date.

    What's Usually Prorated:

    • ✓ Base monthly rent
    • ✓ Pet rent (sometimes)

    What's Often NOT Prorated:

    • ✕ Utilities (unless specified)
    • ✕ Parking fees
    • ✕ Storage fees
    • ✕ Application/admin fees

    Mistake #5: Confusing Prorated Rent with Security Deposits

    Some tenants mistakenly believe landlords can automatically deduct final month's prorated rent from their security deposit. In most states, this is illegal without your written authorization. Security deposits are specifically designated for damages and unpaid rent after proper billing - not for automatic rent deduction.

    Frequently Asked Questions
    Common questions about prorated rent calculations

    How Much Is Prorated Rent? [Examples by Rent Amount and Move-In Date]

    How much prorated rent you owe depends on your monthly rent, the number of days in the month, and your move-in date. The formula: Daily Rate × Days Occupied = Prorated Rent. Here are real examples across common rent amounts:

    Monthly RentMove-In Date (30-day month)Days OccupiedDaily RateProrated Rent
    $1,000June 1516$33.33$533.33
    $1,200June 1516$40.00$640.00
    $1,500June 1516$50.00$800.00
    $1,500June 2011$50.00$550.00
    $2,000June 1516$66.67$1,066.67
    $2,500June 1021$83.33$1,750.00
    $3,000June 1516$100.00$1,600.00

    Quick formula: Divide your monthly rent by the number of days in the month to get the daily rate. Multiply by days occupied (including move-in day). For a $1,500/month apartment moving in June 15: $1,500 ÷ 30 days = $50/day × 16 days = $800 prorated rent.

    Actual amounts vary by month (31-day months like January have a lower daily rate than 28-day months like February). Use the prorated rent calculator above to get the exact figure for your specific dates - it automatically accounts for the correct number of days in each month.

    What Does Prorate Mean? Definition & Examples

    Prorate means to divide or distribute proportionally based on time or usage. In rental terms, to prorate rent is to calculate the exact amount owed for a partial period rather than the full monthly amount. The word comes from the Latin phrase "pro rata," meaning "in proportion."

    When landlords prorate rent, they're ensuring tenants pay fairly for only the days they occupy the property. For example, if you move into a $1,500/month apartment on the 20th of a 30-day month, your landlord would prorate your first month's rent to $550 (11 days × $50/day) instead of charging the full $1,500.

    Common Uses of "Prorate" in Real Estate:

    • Prorate rent for move-in/move-out partial months
    • Prorate utilities based on days of service
    • Prorate property taxes at closing between buyer and seller
    • Prorate HOA fees when ownership transfers mid-month

    Understanding Proration: How Rent Proration Works

    Proration is the process of dividing a payment or charge proportionally. In residential leasing, rent proration ensures both landlords and tenants are treated fairly during partial month occupancy. The proration formula divides the monthly rent by days in the month, then multiplies by days occupied.

    Move-In Proration

    When your lease starts mid-month, proration calculates rent from your move-in date through the end of that month. Your first payment is less than a full month's rent.

    (Monthly Rent ÷ Days in Month) × Days from Move-In to End of Month

    Move-Out Proration

    When your lease ends mid-month, proration calculates rent from the 1st through your move-out date. Your final payment is less than a full month's rent.

    (Monthly Rent ÷ Days in Month) × Days from 1st to Move-Out Date

    Pro Rata vs Prorated: What's the Difference?

    Pro rata and prorated are often used interchangeably, but there's a subtle distinction. "Pro rata" is the Latin term meaning "in proportion," while "prorated" is the English verb form describing the action of dividing proportionally. In practice, they mean the same thing when applied to rent calculations.

    Quick Reference:

    • Pro rata (adjective/adverb): "The rent will be calculated pro rata based on occupancy days."
    • Prorate (verb): "The landlord will prorate the first month's rent."
    • Prorated (past tense/adjective): "Your prorated rent for January is $650."
    • Proration (noun): "The proration was calculated using actual days in the month."

    Whether your lease says "pro rata" or "prorated," the calculation method is the same: divide the monthly rent by days in the month, then multiply by the number of days you occupy the property.

    Prorated Meaning in Rental Agreements

    In rental agreements, prorated means rent that has been adjusted proportionally for a partial rental period. When you see "prorated rent" in your lease, it indicates you'll pay a reduced amount for any month where you don't occupy the property for the full calendar period.

    The prorated meaning extends beyond just base rent. Many lease agreements also prorate pet fees, parking charges, and other monthly costs when applicable. Understanding what's prorated (and what isn't) in your specific lease helps avoid surprises during move-in or move-out.

    Prorated Rent Calculator for Move-In

    Use our prorated rent calculator for move-in whenever your lease starts mid-month. You only pay for the days you actually occupy the unit - from your move-in date through the last day of that month. Enter your rent and move-in date in the calculator above to get your exact amount instantly.

    Move-In Proration Formula

    Daily Rate = Monthly Rent ÷ Days in Move-In Month
    Prorated Amount = Daily Rate × Days Remaining in Month (including move-in day)
    Move-In: March 15
    $1,500 rent, 31-day month
    $822.58
    $1,500 ÷ 31 × 17 days
    Move-In: June 20
    $2,000 rent, 30-day month
    $733.33
    $2,000 ÷ 30 × 11 days
    Move-In: Feb 10
    $1,800 rent, 28-day month
    $1,221.43
    $1,800 ÷ 28 × 19 days

    Our free prorate calculator for move-in automatically uses the actual number of days in your move-in month - so a February move-in (28 or 29 days) gives a different daily rate than a March move-in (31 days). Always verify the calculation method your lease specifies before signing.

    Prorated Rent Calculator for Move-Out

    Use our move-out prorated rent calculator when your lease ends mid-month. Your final rent payment covers only the days you occupied the unit - from the 1st of the month through your move-out date. Enter your rent and move-out date in the calculator above; leave the move-in date blank.

    Move-Out Proration Formula

    Daily Rate = Monthly Rent ÷ Days in Move-Out Month
    Prorated Amount = Daily Rate × Move-Out Day (days from 1st through move-out date)
    Move-Out: March 20
    $1,500 rent, 31-day month
    $967.74
    $1,500 ÷ 31 × 20 days
    Move-Out: June 10

    $964.29
    $1,800 ÷ 28 × 15 days

    Rent Proration Calculator: 3 Methods Compared

    A rent proration calculator can use three different methods. Our calculator defaults to the daily rate method - the industry standard for residential rentals - but you can switch methods above:

    MethodFormula$1,500/mo · 20 days in March (31-day month)Common Use
    Daily Rate (Recommended)Rent ÷ Days in Month × Days$967.74 ($1,500 ÷ 31 × 20)Most landlords; most accurate
    30-Day MethodRent ÷ 30 × Days$1,000.00 ($1,500 ÷ 30 × 20)Some older leases
    Annual Method(Rent × 12) ÷ 365 × Days$986.30 ($18,000 ÷ 365 × 20)Some commercial leases

    Use the prorate calculator above and select your preferred method from the dropdown. The daily rate method is the standard for all 50 states' residential rentals - check your lease to confirm which method your landlord uses before move-in or move-out.

    Prorated Rent Formula: The Exact Math [With 3 Examples]

    The standard prorated rent formula divides monthly rent by the number of days in the month, then multiplies by the number of days occupied. This is the method used by the majority of landlords, property managers, and courts across the United States.

    Prorated Rent Formula

    (Monthly Rent ÷ Days in Month) × Days Occupied

    Standard daily-rate method - used in all 50 states

    3 Prorated Rent Formula Examples

    Example 1: Move-In on the 15th

    $1,500 rent, move-in March 15, 31-day month

    Daily rate: $1,500 ÷ 31 = $48.39/day

    Days occupied: 17 (Mar 15-31)

    Prorated rent: $48.39 × 17 = $822.58

    Example 2: Move-Out on the 20th

    $2,000 rent, move-out April 20, 30-day month

    Daily rate: $2,000 ÷ 30 = $66.67/day

    Days occupied: 20 (Apr 1-20)

    Prorated rent: $66.67 × 20 = $1,333.40

    Example 3: February Move-In

    $1,800 rent, move-in Feb 10, 28-day month

    Daily rate: $1,800 ÷ 28 = $64.29/day

    Days occupied: 19 (Feb 10-28)

    Prorated rent: $64.29 × 19 = $1,221.43

    The prorated rent formula uses actual days in each month - February has 28 or 29 days, other months have 30 or 31. Always use the actual calendar days for the specific month of move-in or move-out; never use a fixed 30-day divisor unless your lease explicitly specifies the "30-day method." The calculator at the top of this page applies the correct formula automatically.

    First Month Prorated Rent: What New Renters Need to Know

    First month prorated rent is the reduced amount you pay when your lease starts mid-month. Instead of paying a full month's rent on day one, you only pay for the days you actually occupy the apartment during that partial month. This is one of the most common scenarios where proration applies.

    How First Month Prorated Rent Works

    1. 1
      Your landlord calculates the daily rate: Monthly Rent ÷ Days in Month
    2. 2
      Count the days from your move-in date through the last day of that month (inclusive)
    3. 3
      Multiply: Daily Rate × Days Remaining = First Month Prorated Rent
    4. 4
      Starting the following month, you pay full rent on the 1st

    For example: If you move in on July 15 at $1,500/month, your first month prorated rent is $822 (17 days × $48.39/day). Your August 1st payment returns to the full $1,500.

    Partial Month Rent: When You Pay Less Than a Full Month

    Partial month rent - also called prorated rent - applies any time you don't occupy a rental unit for a complete calendar month. The two most common situations are move-in (your lease starts mid-month) and move-out (your lease ends before the last day of the month).

    When Partial Month Rent Applies

    • • Move-in on any day other than the 1st
    • • Move-out before the last day of the month
    • • Lease starts or ends mid-month
    • • Early termination with landlord agreement
    • • Month-to-month tenancy ending mid-month

    When Full Month Rent Applies

    • • Lease starts on the 1st of the month
    • • Move-out on the last day of the month
    • • Standard monthly payment periods
    • • Any month with 100% occupancy

    Is your landlord required to prorate rent? While most states don't have explicit laws mandating partial month rent proration, it's widely recognized as standard industry practice and is enforceable as an implied term in most residential leases. If your lease is silent on proration, the daily rate method is the default that courts typically apply. Use the calculator above to calculate your exact partial month rent amount.

    Last Month Rent Calculator: What You Owe for Your Final Partial Month

    A last month rent calculator computes what you owe when your lease ends mid-month. Instead of paying a full month, you pay only for the days you actually occupy the unit - from the 1st through your move-out date.

    Step 1
    Enter your monthly rent in the calculator above
    Step 2
    Leave move-in date blank; enter your last day in the unit
    Step 3
    Get your exact last month prorated rent instantly
    Last Month Rent Formula
    Last Month Rent = Monthly Rent ÷ Days in That Month × Days Occupied
    Example: $1,500/month, moving out on March 12 (31-day month):
    $1,500 ÷ 31 × 12 = $580.65 owed for last month

    Daily Rent Rate: How Much Does Your Rent Cost Per Day?

    Your daily rent rate is the foundation of any prorated rent calculation. It tells you exactly how much one day of rent costs - and it changes every month because different months have different numbers of days.

    Daily Rate Formula
    Daily Rate = Monthly Rent ÷ Days in That Month
    $1,500 rent in January (31 days): $48.39/day
    $1,500 rent in April (30 days): $50.00/day
    $1,500 rent in February (28 days): $53.57/day
    Quick Daily Rate Reference
    $1,000/mo rent:$33.33/day (30-day) · $32.26/day (31-day)
    $1,500/mo rent:$50/day (30-day) · $48.39/day (31-day)
    $2,000/mo rent:$66.67/day (30-day) · $64.52/day (31-day)
    $2,500/mo rent:$83.33/day (30-day) · $80.65/day (31-day)

    Use the prorated rent calculator above to calculate your exact daily rate for any rent amount and month - it automatically accounts for the actual number of days in that specific month.
