Introduction

Extra principal payments reduce the balance faster, which lowers future interest charges and can shorten the loan by years. This calculator shows how lump-sum, monthly, yearly, or one-time extras change your payoff date and total interest.

Paying Off Your Mortgage Early

Extra principal payments reduce the balance faster, which lowers future interest charges and can shorten the loan by years. This calculator shows how lump-sum, monthly, yearly, or one-time extras change your payoff date and total interest.

Pay Extra on Principal

Specify that additional amounts go to principal, not escrow or fees. Even $100 per month on a 30-year mortgage can save tens of thousands in interest depending on rate and balance.

Biweekly Payments

Paying half your monthly payment every two weeks results in 26 half-payments per year—equivalent to 13 full monthly payments. That extra payment accelerates payoff without a large budget jump.

Opportunity Cost

Compare mortgage rate to after-tax investment returns and emergency fund needs. Paying off a 3% mortgage may not beat long-term diversified investing, but eliminating a 7% loan is often compelling.

How It Works

  1. Enter your amounts, rates, and term in the form. Use the same units shown in the labels (dollars, years, percent).
  2. Click Calculate to run the Mortgage Payoff Calculator engine. Invalid or empty required fields show a clear error message.
  3. Review the summary cards for the key outputs. Expand schedules or tables when available for period-by-period detail.
  4. Copy, print, or share your scenario link. Reset the form anytime to start a fresh comparison.

Formula

Each month: balance grows by interest, then payment (plus extras) reduces principal. Biweekly mode adds one extra monthly payment per year. Compare total interest and months to zero balance.
