How to use the Prorated Rent Calculator
- Enter the monthly rent and whether you are moving in or moving out.
- Enter the first day you rent when moving in, or the last day when moving out.
- Choose how the daily rate is worked out, and read the rent for the part of the month.
The formula
days charged (moving in) = days in the month − move-in day + 1days charged (moving out) = move-out dayprorated rent = daily rate × days chargedThe daily rate is the monthly rent divided by the days in that month, a year’s rent divided by the days in that year (365, or 366 in a leap year), or the monthly rent divided by 30, whichever you choose.
Checking a landlord’s figure
If a figure you have been given does not match, try the other methods. A difference of a day usually means the move-in or move-out day was counted differently. Anything else is worth asking about.
What this does not cover
Security deposits, fees, late charges and utilities, and any rule a local law sets for proration. This page does the arithmetic on the method you choose; it does not say which method applies to a tenancy.
With your numbers
- Days charged = 14 of 31
- Daily rate = $1,500.00 ÷ 31 = $48.39, rounded for display
- Prorated rent = $1,500.00 ÷ 31 × 14 = $677.42

Common questions about the Prorated Rent Calculator
- Is the move-in day charged?
- On this page, yes. Moving in on the 18th of a 31-day month charges the 18th to the 31st, which is 14 days. Moving out on the 10th charges the 1st to the 10th. If your lease counts days differently, adjust the date by one.
- Which daily rate method is right?
- There is no single rule. Dividing by the days in that month is common and means a full month always costs the full rent. Dividing a year’s rent by 365 gives the same daily rate every month. Dividing by 30 is simple. Both of those charge more than the full rent for a whole 31-day month, and the page notes it when that happens. Your lease may say which to use, and in some places local law does.
- Why do the three methods give different answers?
- Because they spread the same rent over a different number of days. For 1,500 moving in on 18 October, dividing by October’s 31 days gives 677.42, by a 365-day year 690.41, and by 30 days 700.00.
- Does this work for a leap year?
- Yes. February has 29 days in a leap year, and the yearly method divides by 366, both taken from the date you enter.
