Compare the estimate with the written terms.

A deposit return date depends on the jurisdiction, the event that starts the deadline, and whether required information such as a forwarding address was provided. Choose the deadline that applies to your situation and this tool adds it to the trigger date. Verify the actual rule before treating the result as a legal deadline.

Worked examples

Thirty-day window

A tenancy ending August 1 with a 30-day window produces an August 31 monitoring date.

Confirm the trigger

Some rules may run from move-out, tenancy termination, key return, or receipt of a forwarding address.

Deposit return date questions

When should a security deposit be returned?

Deadlines differ by jurisdiction and tenancy. Check the applicable primary source, then use this calculator to add the correct window.

Does the deadline start on move-out day?

Not always. The trigger can depend on tenancy termination, possession, keys, or required address information.

Does the result include mail delivery time?

No. It adds calendar days only and does not decide whether mailing by the deadline is sufficient.
