How to Calculate Loan Payoff Time

Formula

The amortization formula determines how many months until your balance reaches zero.

Increasing your monthly payment even slightly dramatically reduces payoff time and total interest.

Common use cases:

  • Find when your loan will be paid off
  • See how extra payments shorten payoff time
  • Calculate total interest over the loan's life
