Biweekly mortgage payments mean paying half of your monthly mortgage payment every two weeks instead of the full amount once a month. Because there are 52 weeks in a year, you end up making 26 half-payments, which equals 13 full monthly payments instead of 12. That one extra payment a year goes straight to your balance and can shave years off your loan.
But are biweekly mortgage payments really worth it? In this guide, you will see how they work, run a real example, and use our free calculator to check your own numbers.
How Biweekly Mortgage Payments Work
With a standard mortgage, you make 12 payments a year. With a biweekly schedule, you pay half of that amount every two weeks, which adds up to 26 payments.
Here is the math in simple terms:
- 12 monthly payments = 12 full payments a year.
- 26 biweekly payments = 13 full payments a year.
That extra full payment is the whole trick. It is applied to your principal, so your balance falls faster, you are charged less interest over time, and the loan ends sooner.
It is important not to confuse this with a semi-monthly schedule, where you pay twice a month. That is 24 payments, which equals exactly 12 full payments, so it does not save you anything.

Enter your loan details to compare a standard monthly schedule with a biweekly schedule. You will see your payoff time, your total interest, and how much you could save.
This calculator estimates principal and interest only. It does not include property taxes, homeowners insurance or mortgage insurance, and real results depend on how your lender applies each payment.
Example: $300,000 Loan at 6.5% for 30 Years
Let’s compare both schedules on the same loan.
| Monthly payments | Biweekly payments | |
|---|---|---|
| Payment amount | About $1,896 each month | About $948 every two weeks |
| Paid per year | About $22,754 | About $24,651 |
| Time to pay off | 30 years | About 24 years |
| Total interest | About $382,600 | About $294,500 |
In this example, biweekly mortgage payments would cut roughly six years off the loan and save about $88,000 in interest. The extra cost is only about $1,896 a year, which works out to roughly $158 more per month. These are estimates, and your results will vary depending on your lender.

Pros of Biweekly Mortgage Payments
- You pay off your loan faster. One extra payment a year can take several years off a 30-year mortgage.
- You pay less interest. A faster-shrinking balance means fewer dollars go to the lender.
- It can feel easier on your budget. If you are paid every two weeks, matching your mortgage to your paycheck can make it simpler to manage.
- You build equity sooner. That gives you more options if you later sell or refinance.
Cons to Consider
- Not every lender offers it. Some lenders do not accept biweekly payments at all, or they hold your payments until the monthly due date, which removes the benefit.
- Some programs charge fees. Certain third-party payment services charge setup or per-payment fees that can eat into your savings.
- Your cash flow gets tighter. You are paying about 8% more per year, so you need room in your budget.
- It is not always the best use of your money. If you carry high-interest debt or have no emergency fund, those usually come first.
3 Ways to Make Biweekly Mortgage Payments
1. Ask your lender for a biweekly program. This is the simplest option if your lender offers it. Ask whether there are fees and whether each payment is applied right away or held until the monthly date.
2. Use a third-party service. These services collect your biweekly payments and send them to your lender. Read the fee terms carefully before signing up, because high fees can cancel out the interest you save.
3. Do it yourself with extra principal payments. You do not need a special program to get the same result. Divide your monthly payment by 12 and add that amount to each monthly payment as extra principal. In our example, that is about $158 a month. It is flexible, it costs nothing, and you can stop any time. You can test different amounts with our mortgage payoff calculator.
Questions to Ask Your Lender First
Before you change how you pay, confirm these points in writing:
- Do you accept biweekly mortgage payments, and is there a fee?
- Is each payment applied to my loan on the day you receive it?
- Is the extra amount applied to principal?
- Is there a prepayment penalty on my loan?
You can read more about your rights and mortgage terms on the Consumer Financial Protection Bureau website.
Are Biweekly Mortgage Payments Better Than Refinancing?
They solve different problems. Biweekly mortgage payments shorten your loan without changing your rate. A refinance can lower your rate or change your term, but it comes with closing costs. Before deciding, check your costs with our refinance break-even calculator. If you have a lump sum and want a lower payment instead, see our guide to mortgage recast vs. refinance.
Who Should Consider Biweekly Mortgage Payments?
Biweekly mortgage payments make the most sense if:
- You get paid every two weeks and have a little extra room each month.
- You have an emergency fund and no high-interest debt.
- Your lender applies the payments right away without fees.
- You want to pay off your home earlier and save on interest.
If your budget is tight, it may be better to keep the standard schedule and make extra payments only when you can.
A Personal Note from José María
I wrote this guide because the idea of biweekly mortgage payments sounds almost too good to be true, and I wanted to show the real numbers, including the catches. I am not a lender, a mortgage broker or a financial advisor, and I run FinanzasClave as an independent site that explains mortgages in plain English. Please use the calculator as a learning tool, and talk to your lender or a licensed professional before changing how you pay your loan. You can also estimate your full monthly cost with our mortgage calculator.
