How much can your landlord charge? When must the money come back? Does it earn interest while they hold it? Pick your state and get real answers with the statute behind every number.
Every figure cites the state statute. Updated October 5, 2026.
Runs entirely in your browser — nothing you type is sent anywhere. Rules shown are state law as of October 2026; see your state's page for sources.
No signup, no email, no upload. The tool is a thin, honest layer on top of the state statutes — and each result links the page that sources it.
The calculator loads your state's cap, return deadline, and interest rule — including the cities that add their own.
Monthly rent, your deposit, and your move-in/move-out dates. Nothing leaves your browser.
Cap check, a deadline you can circle on a calendar, and the interest your state owes you — with the statute behind each figure.
Move-in day is where every deposit story starts — and where the documentation should start with it.
Each guide covers the deposit cap, the return deadline, interest requirements, bad-faith penalties, and the statute citation — written in plain English and dated.
The practical side of deposit law: documentation at move-in, the demand letter at move-out, and the clauses that decide the outcome before you ever sign.
