Work out loan payoff date instantly with clear inputs, formula shown and shareable results.
The payoff date follows from the number of instalments needed to clear the balance at the chosen payment, counted forward from the first payment date. It converts an abstract tenure into the calendar date the debt actually ends.
Payoff date
n = -ln(1 - B·r/payment)/ln(1+r), rounded up; date = first payment + (n-1) months
Figures are estimates. Lenders apply their own rounding, fees and eligibility rules, and rates change. This is not financial advice — confirm the numbers with your lender.
The final instalment is usually smaller than the rest, but it still falls in its own month.
Then no payoff date exists at that payment level — the balance would never reach zero.
