MortgageCalc
Mortgage Payoff Calculator with Extra Payments & Amortization Schedule
Use our Mortgage Payoff Calculator with Extra Payments to model how recurring principal contributions, annual bonuses, or one-time lump-sum prepayments eliminate years off your loan term and save tens of thousands of dollars in lifetime interest.
How Do Extra Principal Payments Accelerate Your Mortgage Payoff Date?
An extra payment mortgage calculator models how adding recurring monthly prepayments or one-time lump sums directly reduces your loan principal. Because mortgage interest compounds on the remaining balance, prepaying principal accelerates your amortization schedule, eliminates years of debt, and saves tens of thousands of dollars in lifetime interest charges.

Why Prepaying Principal Yields a Guaranteed Return on Investment
Prepaying your mortgage principal is equivalent to earning a guaranteed, risk-free, tax-free return equal to your mortgage interest rate. On a 6.50% 30-year fixed loan, every extra dollar applied directly to principal avoids 6.50% compounding interest over the remaining life of the note.
Frequently Asked Questions
Can my lender penalize me for making extra mortgage payments?
Under the Dodd-Frank Wall Street Reform Act, nearly all modern residential conventional, FHA, and VA loans are classified as Qualified Mortgages (QM) and carry zero prepayment penalties. You can prepay principal at any time without fees.
