Prorated rent calculator

Work out the rent for a partial month when a tenant moves in or out mid-month. See the amount by all three common methods and pick the one your lease uses.

The tenant is

Days in that month

$241.94

5 days × $48.39/day (rent ÷ days in the month)

365-day year

$246.58

5 days × $49.32/day (rent × 12 ÷ 365)

30-day month

$200.00

4 days × $50.00/day (rent ÷ 30)

For guidance only, not legal or financial advice. Your lease and your state's or city's rules come first.

How prorated rent is calculated

Prorated rent is the monthly rent split by the days the tenant actually has the home. Find a daily rate, then multiply it by the days they occupy it that month. The move-in day and the move-out day both count.

  • Days in that month: rent ÷ the number of days in that month (28 to 31). The most common method, and the fairest month to month.
  • 365-day year: rent × 12 ÷ 365, so every day costs the same all year.
  • 30-day month: rent ÷ 30, the simplest to explain. Some leases use it for every month.

Example

A tenant moves in on June 21 to a home that rents for $1,500 a month. June has 30 days, so the daily rate is $50 and they have the home for 10 days (June 21 to 30): the prorated rent for June is $500.

Questions landlords ask

Which method should I use?
The one your lease names. If it says nothing, landlords usually use the actual days in that month. Whichever you choose, write it in the lease and use it the same way for every tenant.
Do I have to prorate rent?
It depends on your lease and local rules. Many landlords prorate the first month so rent is due on the 1st after that. Check your state's or city's rules for move-outs.
Is the move-in day counted?
Yes. This calculator counts the move-in day through the last day of the month, and the 1st of the month through the move-out day.
