Important limitations
Deposit caps, interest and refund rules vary by state and local law.
Interest is not a legal entitlement calculation
Use the interest method, years and rate shown by this form for a numerical scenario. Lease rules can specify another rate, a different interest period, deductions or a deadline. The result does not establish that interest is owed or that an entered deduction is permitted; compare it with the contract and applicable local requirements.
