How landlords should calculate a security deposit refund
Most states require landlords to return a tenant's security deposit — or a written, itemized list of deductions — within a fixed number of days after move-out. Missing that deadline, or withholding money without an itemized reason, can expose a landlord to penalties well beyond the deposit itself, including double or triple damages in some states.
This calculator applies your state's statutory deadline and (where applicable) interest requirements to your numbers, then shows the exact refund amount and due date. It is meant to help you move quickly and correctly after a tenant moves out — it does not replace reviewing your state's statute or, for contested amounts, talking to a local attorney.
