FREE OWNER CALCULATOR
What’s the exact rent for a partial month?
Enter the full monthly rent and the exact dates occupied. Actual-days and standardized-30-day are both real lease conventions—they don’t always agree, so this shows both.
Calculate a prorated rent amount
Enter the full monthly rent and the exact dates occupied within the month. Every figure is editable.
16 days occupied out of 30, at $100.00/day.
What the estimate means
Days occupied (inclusive of both the start and end date), divided by either the real days in that calendar month or a standardized 30-day month, times the daily rate.
CAM or other pass-through charges that may be prorated on a different basis than base rent, or a lease that specifies a different proration formula entirely.
Confirm a move-in or move-out charge by hand, or check which proration method a lease actually uses before disputing an amount.
