Pick the state — and the city or county, where one has its own rule — and get the interest
owed on a security deposit, year by year, with every rate cited to the official series it
came from. Where a state publishes its own calculator or formula, this tool reproduces that
official arithmetic; where the law pays whatever the account actually earned, the tool says
so and computes on the rate you supply. See every state's law at deposit interest laws by state.
Not legal advice. This tool produces an estimate built
from the cited state statutes, which were accurate as of the verified date shown. Laws change,
cities and counties may add stricter rules not covered here, and some states require specific
forms, statutory language, or delivery methods this result does not replicate. Review the rule
text and citations on this page — and, when in doubt, a licensed attorney in your state — before
relying on it.
