About Loan Payoff Date Calculator

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.

Formula

Payoff date

n = -ln(1 - B·r/payment)/ln(1+r), rounded up; date = first payment + (n-1) months

Worked example

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or fees or charges into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • 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.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why round the months up?

The final instalment is usually smaller than the rest, but it still falls in its own month.

What if the payment barely covers interest?

Then no payoff date exists at that payment level — the balance would never reach zero.
