Prorated Rent Calculator

Prorated rent is calculated by dividing the monthly rent by the number of days in the month to get a daily rate, then multiplying by the number of days occupied. For example, $1,800 rent with a move-in on the 15th of a 30-day month: $1,800/30 = $60/day x 16 days = $960.

The banker's method divides rent by 30 regardless of the actual days in the month, simplifying calculations. The actual-days method divides by the real number of days (28, 29, 30, or 31). The banker's method may slightly favor or disadvantage tenants depending on the month.

Prorated rent for a move-in is typically due on the move-in date along with the security deposit and sometimes first and last month's rent. For move-outs, the prorated amount may be the only rent due for the final month.
