Prorated Rent Calculator
Figure out exactly how much rent you owe for a partial month. Whether you are moving in on the 15th or moving out on the 10th, this calculator breaks your monthly rent into a daily rate and multiplies by the days you actually occupy the unit.
Prorated rent is simple: divide your monthly rent by the number of days in the month to get a daily rate, then multiply by the days you will actually live there. If your rent is $1,500 and you move into a 30-day month on the 16th, you occupy 15 days. Your daily rate is $50, so you owe $750 for that partial month.
Landlords typically use one of two methods: dividing by the actual days in the calendar month (28, 30, or 31), or using a banker's month of 30 days. The calendar-day method is more common and what this calculator uses. Always check your lease to confirm which method applies.
Some landlords prorate the first month and require full payment on the last month, while others prorate both. If you are negotiating a lease start date, moving in later in the month means a smaller first payment, which can help with upfront costs like security deposits and moving expenses.
