How does paying biweekly save money if the total dollar amount is similar?

26 biweekly half-payments equal 13 monthly payments a year instead of 12, applying one extra payment to principal annually.

Can I just make one extra payment a year myself instead of switching to biweekly?

Yes, the math is essentially the same and avoids any biweekly program fees some servicers charge.

Do all mortgage servicers offer biweekly payment plans?

Not all do; confirm the servicer applies payments to principal as received rather than holding funds until a full monthly payment accrues.

Is biweekly billing the same as paying every two weeks by payday?

Only if timed that way; the savings come from the extra annual payment, not the payday cycle itself.

Does biweekly payment change my interest rate?

No, the rate stays the same; savings come from paying down principal faster.

How Biweekly Mortgage Payments Work

The Mechanism Behind the Savings

Paying half your monthly payment every two weeks results in 26 half-payments per year — equivalent to 13 monthly payments instead of 12. That extra payment goes entirely toward principal.

Example: $290,000 Loan at 6.5% Over 30 Years

Standard schedule: ~$1,833/month, ~$370,000 total interest. Biweekly schedule ($916.50 every two weeks): paid off in ~25 years 2 months, saving nearly 5 years and ~$61,000 in interest.

Ways to Implement a Biweekly Strategy

Lender-sponsored biweekly program (watch for fees)
DIY biweekly payments (one extra full payment yearly, no fees)
Direct biweekly payments through your servicer

What to Confirm With Your Servicer

Some servicers hold biweekly payments until they total a full monthly payment before applying them — ask directly how payments are processed.

Why Timing Matters

Starting a biweekly schedule early in a 30-year mortgage produces significantly more savings than starting in year 20.

An Alternative Without Changing Payment Frequency

Add 1/12th of your monthly payment as extra principal each month to achieve a similar result without switching to biweekly payments.
