Security Deposit Interest Calculator

Estimate interest on your rental deposit. State rules decide whether interest is required, which rate applies, and when it must be paid.

Estimate your deposit interest

Choose your state and enter your deposit and dates. Nothing you enter leaves this page.

This estimate holds the selected rate constant for the whole period. Past or future rates may differ. It assumes interest has not already been paid and does not apply forfeiture rules.
