Our Mortgage Length Calculator helps you quickly determine how long it will take to pay off your home loan based on principal, interest rate, and your monthly payment. Plan your mortgage payoff strategy and achieve financial freedom sooner.

Formula:

The formula to calculate the number of monthly payments (n) for a mortgage is:

n = -log(1 - (P * i) / M) / log(1 + i)

Where:

  • P = Loan Principal (the initial amount borrowed)
  • M = Monthly Payment (the fixed amount you pay each month)
  • i = Monthly Interest Rate (Annual Interest Rate / 12 / 100)

Once n is determined, the total length is calculated by dividing n by 12 to get years and the remainder by months.
