Questions answered
What to know before using the result.
Are both the start and end dates billed?
This calculator counts both dates. Change the end date if your lease uses an exclusive move-out date.
Which rent-proration method should I use?
Use the method stated in your lease. Actual-day, 30-day, annual and custom-period results are shown together for comparison.
Does this determine what a tenant legally owes?
No. The lease and applicable local law control the final amount.
