The 13th Payment Magic
By splitting your payment in half and paying every two weeks, you naturally make 26 half-payments a year. That equals 13 full monthly payments instead of 12.
Pay Every Two Weeks, Save Over Time
A biweekly mortgage plan splits your monthly mortgage payment into two half-payments every two weeks.
Because there are 52 weeks in a year, this can create 26 half-payments, which equals 13 full monthly payments instead of 12. That extra payment can reduce your principal faster and may lower total interest over time.
Payment Split
With biweekly payments, you pay half of your regular mortgage payment every two weeks.
This can feel easier for your budget than having to come up with one large extra payment at the end of the year.
Principal Impact
The extra yearly payment works best when it goes toward principal.
Lower principal means less balance for interest to build on, which can shorten the life of the loan.

A biweekly mortgage calculator is useful when you want to compare:
- Monthly vs biweekly payments
- Total interest saved
- Your new payoff date
- Extra principal impact
- Regular biweekly vs biweekly plus extra payments
Interest Savings & Fees
Biweekly payments may reduce total interest because your principal balance can drop faster. The savings depend on your loan balance, rate, payment timing, and how your lender applies the payments.
Fee Check
Some lenders or third-party services may charge fees for biweekly payment plans. Before signing up, ask if you can make extra principal payments yourself without paying extra service charges.
Quick Answers
How does a biweekly mortgage payment work?
Instead of making one full payment per month, you pay exactly half of your monthly payment every two weeks. Because there are 52 weeks in a year, you end up making 26 half-payments, which equates to 13 full payments over the year.
Does a biweekly payment actually save money?
Yes. That extra 13th payment goes directly toward your principal balance. By reducing your principal faster, you pay less total interest over the life of the loan and pay off the mortgage several years early.
Can I achieve the same savings without a biweekly plan?
Yes. You can achieve the exact same financial result by simply making one extra full principal payment per year, or by dividing your monthly payment by 12 and adding that amount to your normal monthly check.
Should I pay a fee to set up a biweekly mortgage?
No. Many third-party companies charge hundreds of dollars to set up a biweekly payment schedule. You can usually arrange this directly with your lender for free, or simply manage the extra payments yourself to avoid unnecessary fees.
