Prorated Rent Calculator
Landlords sometimes "forget" to prorate and charge you a full month for 16 days. Your prorated rent is (monthly rent / days in month) x days occupied. This calculator handles both the standard 30-day method and actual calendar day method — and February prorations can differ by $25-50 between the two, so pick the one that favors you.
Prorated rent is the exact amount you owe for a partial month when moving in or out mid-month. Divide your monthly rent by the number of days in the month (or use the standard 30-day method), then multiply by the days you'll occupy the unit. Enter your rent and dates below for an instant calculation with both methods compared.
