What Is a Late Fee?

A late fee is a charge applied when a payment is not received by its due date. Credit cards, loans, rent agreements, and utility bills commonly include late fees, which may be a flat amount or a percentage of the amount due. The amount and any grace days are set by the contract and by applicable law.

Other Consequences

Beyond the fee, late payments can trigger a penalty APR on credit cards and, once reported to credit bureaus, can affect credit history.

Late Fee vs. Late Interest

A late fee is a one-time charge; late payment interest accrues over time on the overdue amount, as with statutory interest on unpaid business invoices.
