How the Prorated Rent Calculator works
Rent per day = monthly rent ÷ days in the month. Prorated rent = rent per day × days from the move-in date to the end of the month, counting the move-in day. Some leases use a fixed 30-day month instead of the actual number of days, so choose the method your lease states. Example: With $1,500 rent and a move-in on October 12, the month has 31 days and 20 of them are charged, so the prorated rent is $967.74.
