Security Deposit Interest Calculator
Most states do not require landlords to pay interest on a security deposit, but some states and cities do. Pick your state to see its rule, then enter the deposit, the yearly interest rate and how long the landlord has held it for an estimate.
This is a simple-interest estimate. Where interest is required, the law may set the rate, let the landlord keep a fee, compound the interest, or apply only to some buildings or cities, so the amount you are owed can differ. Use the rate your state or city sets, or the rate the bank account pays.
