Calculate the exact late fee owed based on days late, grace period, and your lease's fee terms.

Enter rent, due date, and paid date to see the late fee owed.

How late fees are calculated

Most leases charge a late fee once rent is a set number of days past due (the grace period). After that, the fee is typically structured one of three ways: a flat one-time charge, a percentage of the monthly rent, or a daily charge that accrues for each day the rent remains unpaid, sometimes capped at a maximum amount.

Check the lease for the exact terms and grace period before charging a fee. Many states also cap how much a landlord can charge in late fees or require the fee to be "reasonable" relative to actual damages — verify your state and local rules before applying one.
