Biweekly Mortgage Comparison Calculator

Compare payment timing and fees before choosing a biweekly plan. Twenty-six half-payments a year are different from paying twice a month.

Biweekly Mortgage Comparison

Would paying every two weeks help?

Paying twice a month is 24 half-payments. Paying every two weeks is about 26: roughly one extra monthly payment each year. Actual savings depend on when your servicer applies the money. Our monthly-credit scenario puts that extra at each year-end; immediate credits use 26 equal interest periods per year. These are illustrations, not a replica of your servicer’s ledger.

Your numbersYour loan typeWhich payment-crediting method should I save?

What you still owe ($)

This is the loan balance today, not the amount you borrowed years ago. Do not use the payoff quote, which can include unpaid interest and fees.

Find “principal balance” on your statement.

Your fixed interest rate (%)

Find the interest rate on your mortgage statement. Use the interest rate, not APR. This tool cannot predict adjustable rates.

For 6.5%, type 6.5.

Scheduled payments left (months)

Use the number of monthly payments remaining if you pay as usual. Ten years left means 10 × 12 = 120. If past extra payments changed your payoff, enter the statement payment below.

Years left × 12.

Statement loan-only payment ($)

Find the principal and interest parts of your monthly bill and add them. Leave out taxes, homeowners insurance, mortgage insurance and HOA. Leave blank to estimate from balance, rate and months left.

Optional: principal + interest only.

Extra principal each month ($)

Example: your required loan-only payment is $1,500. Paying $1,600 means $100 extra. Tell the servicer to apply extra money to principal. A payoff-date goal calculates this amount for you.
