How a mortgage payoff target works

A mortgage payoff goal starts with your current balance, interest rate and the number of months remaining on your loan.

LoanMathWorks first estimates the principal-and-interest payment required to finish the loan on its current schedule. It then calculates the payment required to amortize the same balance over your shorter target period.

Shortening the term

Paying the balance over fewer months requires a larger monthly payment, but the loan balance declines faster.

Potential interest savings

Because interest is generally calculated using the outstanding balance, paying principal down more quickly can reduce the amount of interest that accrues over the remaining life of the loan.

Choosing a realistic target

A dramatically shorter payoff period can require a significantly larger monthly payment. Try several target periods to compare the additional payment required with the estimated interest savings.

Mortgage Payoff FAQ

Frequently asked questions

How much extra do I need to pay to pay off my mortgage early?

The amount depends on your remaining balance, interest rate, current repayment period and target payoff date. This calculator estimates the payment needed and subtracts your normal scheduled payment to show the additional monthly amount.

Why does paying the mortgage faster reduce interest?

Mortgage interest is generally based on the unpaid principal balance. Reducing that balance more quickly can decrease the amount of future interest that accrues.

Does this calculator include property taxes and insurance?

No. The payoff calculation focuses on loan principal and interest. Property taxes, homeowners insurance and HOA expenses generally do not change the mortgage principal payoff calculation.

Can I enter a payoff goal that is only a few years away?

Yes, provided the target period is shorter than your current remaining term. A very short target may result in a substantially higher required monthly payment.

Is paying off a mortgage early always the best financial choice?

Not necessarily. Paying down a mortgage faster can reduce interest, but financial decisions may also involve emergency savings, retirement contributions, other debts, taxes and investment alternatives.

Should I verify extra payments with my mortgage servicer?

Yes. Confirm how additional funds are applied and review your mortgage agreement for any relevant prepayment rules or restrictions.
