How Biweekly Payments Work
1. Pay Every 2 Weeks
Instead of 12 monthly payments, you make 26 biweekly payments (half of your monthly payment).
2. Make 13 Payments
26 biweekly payments = 13 monthly payments per year. That's one extra payment automatically!
3. Save Years & Interest
Extra principal payments reduce your balance faster, saving years and thousands in interest.
How Biweekly Mortgage Payments Work
With a standard monthly mortgage, you make 12 payments per year. When you switch to biweekly payments, you make one payment every two weeks — that's 26 half-payments, which equals 13 full monthly payments per year. That one extra payment per year goes entirely toward principal, accelerating your payoff timeline significantly.
On a $400,000 mortgage at 7% interest over 30 years, the typical homeowner pays roughly $558,000 in total interest. Switching to biweekly payments reduces that total by approximately $70,000 and cuts the loan term by around 4–5 years.
Biweekly vs. Monthly Payments: Key Differences
| Factor | Monthly | Biweekly |
|---|---|---|
| Payments per year | 12 | 26 (= 13 monthly) |
| Extra principal/year | $0 | 1 full payment |
| Interest saved ($400K @ 7%) | — | ~$70,000 |
| Payoff time reduction | — | 4–5 years faster |
How to Set Up Biweekly Payments
There are three ways to implement biweekly payments:
- Through your lender: Many servicers offer an official biweekly payment program. Ask your lender directly — some charge a setup fee of $200–$400.
- DIY method: Divide your monthly payment by 12 and add that amount to each monthly payment as extra principal. This achieves the same result for free.
- Automatic bank transfer: Set up a biweekly auto-transfer to a savings account, then apply the accumulated balance as an extra payment each year.
Frequently Asked Questions
Is biweekly mortgage payment a good idea?
Yes, for most homeowners. If you plan to stay in your home long-term and want to build equity faster while reducing total interest paid, biweekly payments are one of the simplest strategies available — no refinancing required.
Does my lender have to accept biweekly payments?
Most lenders accept extra principal payments. However, not all will automatically apply biweekly payments correctly — some hold partial payments until they reach a full monthly amount. Always confirm with your servicer how they handle accelerated payments.
What if I can't commit to biweekly payments permanently?
You don't have to commit permanently. Even making one extra mortgage payment per year has nearly the same effect. Use this calculator to see how much you'd save with any extra payment frequency.
Can I save more by refinancing instead?
Refinancing can lower your rate, which reduces interest more dramatically — but it comes with closing costs of 2–4% of the loan amount. Biweekly payments cost nothing and work on top of any rate you already have.
