How to calculate prorated rent

  1. Enter the rentYour full monthly rent.
  2. Pick move-in or move-outAnd the exact date.
  3. Choose the methodMatch your lease, or compare all three.

The three proration methods

Rent proration turns a monthly price into a daily one. The choice of divisor is what separates the methods, and over a single partial month the difference is usually small but real.

For a move-in on the 20th of a 30-day month, you occupy 11 days (20th to 30th inclusive). At $1,500 a month that is $50 a day, or $550 prorated.

Days in month

Rent / days in that month.

Yearly

Rent x 12 / days in the year.

Banker’s month

Rent / 30, at most 30 days.

Prorated rent FAQ

How is prorated rent calculated?

Daily rent multiplied by the days you occupy the unit. The most common daily rent is monthly rent divided by the number of days in that month.

Which proration method is correct?

The one in your lease. If the lease is silent, the days-in-month method is the most common. Some landlords use rent x 12 / 365, and some use a 30-day month.

Is the move-in day counted?

Usually yes: if you get the keys on the 20th you pay for the 20th. Untick the option to exclude the move date if your lease says so.

How many days are charged when I move out?

From the 1st of the month up to and including the move-out day, unless you exclude the move date.

Why do the methods give different amounts?

Daily rent changes with the divisor. In a 31-day month the days-in-month daily rate is lower than the 30-day banker rate, and in February it is higher.
