Mortgage Payoff Calculator

Quick answer: Enter your current principal balance and remaining months. Extra monthly, annual and immediate one-time principal reduce interest while the original required P&I payment stays unchanged.

Monthly accrual approximation; taxes, insurance, penalties, interest deductions and investment alternatives excluded. No recast is assumed. Ask the servicer how to designate extra principal and request a dated payoff statement before paying the loan in full.

How to pay off a mortgage faster

Quick answer: Extra principal can shorten the payoff period and reduce interest because later interest is calculated on a smaller balance. Compare a sustainable extra amount, keep emergency reserves and verify how the servicer applies additional payments.

Use the remaining loan

Enter the current principal balance, note rate and remaining term—not the original purchase price and original term.

Compare exact targets

Test $100, $250 or $500 monthly, one extra payment a year, or the amount required to finish five years earlier.

Payoff versus investing

Interest avoided is relatively certain; investment returns are uncertain and may be taxable. Liquidity and risk tolerance matter.

Scenarios to calculate

  • Pay the mortgage off 5 years early.
  • Compare biweekly-equivalent payments with monthly extra principal.
  • Estimate the payment needed for a 10-year or 15-year payoff target.

Next: review payoff strategies, compare payoff versus investing, view an amortization schedule.

How to calculate a faster mortgage payoff

Enter the current principal balance, remaining months, note rate and extra principal directly. Monthly, annual and immediate one-time payments are modeled without reducing the original required payment. The extra-payment view compares the scheduled loan with the accelerated plan. Results are estimates; your servicer's daily interest, payment timing and escrow handling can create small differences.

Extra-payment scenarios worth comparing

  • Monthly extra principal: test $100, $250, $500 or an amount that fits your cash-flow plan.
  • Biweekly equivalent: compare one additional monthly payment per year with a true servicer-supported biweekly plan.
  • Five-year target: increase extra principal until the modeled payoff date is about five years earlier.
  • Payoff versus investing: compare the guaranteed interest avoided with the uncertain, taxable return of an alternative investment.

Before sending extra principal

Confirm that your loan has no prepayment penalty, maintain an emergency reserve, and tell the servicer to apply the additional amount to principal. Paying a mortgage by credit card usually adds fees or cash-advance risk and is not the same as making an extra principal payment.

Also compare the amortization calculator, the mortgage payoff strategy guide, and the payoff-versus-investing guide.

Frequently Asked Questions

Does an extra payment lower my required payment?

Not automatically. Extra principal generally shortens payoff and reduces interest while the contractual payment remains due. A servicer-approved recast is a different transaction.

Can I enter a one-time lump sum?

Yes. This model applies it immediately to principal while keeping the original required payment. An annual extra payment is applied every 12 months.

Does this include escrow?

No. Taxes, homeowners insurance and escrow refunds are separate from loan principal and interest. They do not disappear when you make extra principal payments.

Is this a payoff statement?

No. Obtain a dated payoff statement from your servicer for daily interest, fees and exact good-through dates before paying the balance in full.

Should I pay fees for a biweekly program?

Compare the quoted setup and debit fees with making extra principal yourself. One extra monthly payment per year can be approximated by adding one-twelfth of the monthly P&I each month, without claiming the timing is identical.
