Does a biweekly plan really save that much interest?

It can meaningfully reduce total interest and shorten the loan term because you are making the equivalent of one extra monthly payment per year applied to principal, but the exact savings depend on your rate, balance, and remaining term.

Will my servicer let me set up biweekly payments myself?

Many servicers offer this through their online portal, sometimes with an option to allow extra amounts to go straight to principal. Others require enrollment in a formal program. Ask directly.

Is it better to just pay extra once a year instead?

For many borrowers, yes. Making one voluntary extra principal payment a year, or adding a bit extra each month, avoids third-party fees and gives you full control over your cash flow.

Do biweekly payments affect my credit score?

Paying down principal faster does not directly boost your score, but consistently on-time payments and a lower balance over time can be a positive factor in overall credit health.

Can I stop a biweekly plan once I start?

If it is a self-managed approach through your own bank account, you can adjust anytime. If it is a formal third-party program, review the enrollment terms, since some require notice to cancel.

Do Biweekly Mortgage Payments Actually Help?

How biweekly mortgage payments create one extra payment a year, how servicers handle them, and alternatives that may work just as well.

Updated 2026-08-17| Applies to: Homeowners looking to pay off their mortgage faster or reduce total interest paid.

The short answer

Biweekly mortgage payments split your monthly payment in half and collect it every two weeks, which results in 26 half-payments (13 full payments) per year instead of 12. That extra payment goes toward principal, which can shorten the loan term and reduce total interest, but the same result can often be achieved for free by simply making one extra principal payment a year.

How does a biweekly payment plan work?

A standard mortgage bills you once a month, 12 times a year. A biweekly plan collects half of your monthly payment every two weeks. Because a year has 52 weeks, that works out to 26 half-payments, which equals 13 full monthly payments instead of 12. The extra payment is applied toward your loan's principal balance, which can reduce the total interest charged over the life of the loan and shorten how long it takes to pay off the mortgage.

The impact depends on your interest rate, loan balance, and how many years remain on the loan. Borrowers with higher rates or longer remaining terms often see a bigger benefit in total interest saved, though results vary by lender and loan type.

How do servicers handle biweekly payments?

This is where borrowers often get tripped up. Some loan servicers will accept and apply biweekly payments as they arrive, crediting principal reduction along the way. Others hold each half-payment in a suspense account until a full monthly payment amount has accumulated, then apply it all at once, which delays the benefit. A few servicers do not support biweekly payments directly and may return partial payments.

Before enrolling in any biweekly program, ask your servicer in writing how partial payments are applied. Some third-party companies market biweekly payment plans for a setup fee or ongoing service charge, but you can usually replicate the same benefit yourself at no cost.

What are the alternatives to a formal biweekly plan?

Make one extra full principal payment per year, timed whenever it is convenient
Add a fixed extra amount to principal with every regular monthly payment
Round your payment up to the next even hundred dollars
Apply windfalls such as tax refunds or bonuses directly to principal

Each of these approaches accomplishes a similar goal to a biweekly plan without a third-party fee, as long as your servicer applies extra funds to principal rather than holding them as a future payment credit. Always specify in writing or through your online portal that extra funds should be applied to principal.

Is a biweekly schedule right for every borrower?

Biweekly payments work best for borrowers with stable income who can comfortably absorb the equivalent of one extra monthly payment spread across the year. If your budget is tight or income is variable, a rigid biweekly commitment through a third-party servicer can create cash flow strain. Making occasional extra principal payments when funds allow offers more flexibility.

Approach	Extra Payments Per Year	Flexibility	Typical Cost
Third-party biweekly service	1 extra	Low, fixed schedule	Setup or ongoing fee possible
Self-managed biweekly	1 extra	Medium	Free, if servicer applies correctly
Occasional lump-sum extra payments	Varies	High	Free
Standard monthly only	0 extra	Highest	Free

Check your loan documents for prepayment penalties before making extra payments. Most conventional, FHA, VA, and USDA loans today do not carry prepayment penalties, but it is worth confirming.

Common mistakes to avoid

Paying a company a setup fee for a biweekly plan you could replicate for free
Assuming extra funds are automatically applied to principal without confirming with the servicer
Committing to a rigid biweekly schedule that strains monthly cash flow
Not checking for a prepayment penalty before making extra payments
