Biweekly vs Monthly Mortgage

Biweekly vs Monthly Mortgage Calculator

This calculator shows the quiet power of paying your mortgage biweekly instead of monthly. The trick is simple: pay half your monthly payment every two weeks. Because there are 52 weeks in a year, you make 26 half-payments, which equals 13 full monthly payments instead of 12. That one extra payment a year goes straight to principal, shortening your loan and cutting the interest you pay, all without changing your budget in any meaningful way.

To use it, enter your loan balance, your interest rate, and the years remaining on the loan. The hero number shows the total interest you save over the life of the loan by going biweekly. One stat card shows how much time you cut off your payoff date, and the other shows the size of each biweekly payment, which is simply half your monthly amount. The chart compares total interest paid under each schedule so the savings are easy to see.

The biweekly approach matters because it is nearly free money. You are not paying more out of pocket in any given month, you are just paying in a rhythm that sneaks in one extra payment a year. On a large, long loan that single extra payment compounds into years off the term and a substantial interest savings. The only catch is confirming that your lender applies biweekly payments without charging a fee.
