What this calculator does
This calculator finds the scheduled maturity date of a fixed-term loan — mortgage, auto, personal, or business — by adding the loan term in months to the origination date. It's a quick way to see exactly when a loan is due to be fully paid off under its original schedule.
Worked example
A 30-year mortgage (360 months) originating on June 1, 2026 has a maturity date of June 1, 2056.
Common mistakes
- Confusing the origination date with the first payment date. Some loans schedule the first payment a month or more after origination — check your loan documents for the exact term start.
- Ignoring extra principal payments. Paying more than the scheduled amount shortens the actual payoff time, so the real payoff date can be earlier than this calculated maturity date.
- Assuming refinancing keeps the same maturity date. A refinanced loan resets the term from the refinance date, producing a new — often later — maturity date.
