How does biweekly mortgage payment work?

Instead of paying once a month, you pay half your monthly mortgage amount every two weeks. Since there are 52 weeks in a year, you make 26 half-payments, which equals 13 full monthly payments per year.

Do banks charge for biweekly payments?

Some lenders or third-party servicers charge a setup fee or transaction fee for biweekly plans. However, you can often achieve the same result for free by manually making one extra principal-only payment each year.

Biweekly Mortgage Savings: How to Save Thousands

Paying your mortgage biweekly is one of the simplest, lowest-risk ways to save tens of thousands of dollars in interest.

Most homeowners pay their mortgage 12 times a year. By switching to a biweekly schedule (paying half every two weeks), you trick the calendar into helping you make one extra full payment every year—painlessly.

How It Works (The 26 vs. 12 Rule)

There are 52 weeks in a year.

Monthly Plan: 12 payments per year.
Biweekly Plan: 52 weeks / 2 = 26 half-payments per year.

26 half-payments is equal to 13 full monthly payments. That one extra payment goes 100% toward your principal balance, reducing your interest for every future month.

How to Start Biweekly Payments

You don't need a special program to do this. You have two options:

The Official Way: Call your lender and ask to switch to biweekly auto-draft.
Warning: Watch out for setup fees.
The DIY Way (Recommended): Take your monthly principal & interest payment, divide it by 12, and add that amount to your monthly payment as "Principal Only".
Example: If payment is $1,200. $1,200 / 12 = $100. Pay $1,300 every month.

Frequently Asked Questions

Can I do this with any mortgage?

Yes, almost all mortgages allow for prepayment without penalty. However, always check your loan documents for "prepayment penalty" clauses (rare in modern qualified mortgages).

Is biweekly better than investing?

It depends on your interest rate. If your mortgage rate is 7%, paying it off is a guaranteed 7% return. If your rate is 3%, you might earn more investing in the stock market (historically 8-10% returns). Biweekly payments are a "safe" investment.
