Read Article →How to Use the Biweekly Mortgage Calculator
- Enter your loan balance, rate, and term — or start from the defaults and adjust.
- The calculator splits your monthly payment in half and schedules 26 half-payments per year — one every two weeks.
- Compare payoff dates and total interest against the normal monthly schedule.
- Stress-test it: compare against simply adding 1/12 of a payment monthly — same money, same result, no enrollment fees.
Why 26 Half-Payments Beat 12 Monthly Payments
The trick is the calendar: 52 weeks ÷ 2 = 26 half-payments = 13 full payments a year — one extra payment, automatically, because months don't align with weeks. On a $300,000, 30-year loan at 6.5%:
- Monthly: $1,896/month, paid off in 30 years, ~$382,600 total interest
- Biweekly ($948 every two weeks): paid off in roughly 24–25 years, saving $68,000–$74,000 in interest
Extra principal early in the loan matters most: in year one of a 30-year loan, only ~$260 of each $1,896 payment is principal — so an extra $1,896/year directly attacks balance at maximum leverage. The full amortization math lives on our mortgage calculator.
The Free Alternative Nobody Advertises
Also verify your servicer applies extra payments to principal, not next month's payment — that single setting decides whether the strategy works.
Biweekly Mortgage FAQ
How much does biweekly payment save on a 30-year mortgage?
On $300,000 at 6.5%, biweekly payments cut roughly 5-6 years off the term and save approximately $68,000-$74,000 in interest.
Is biweekly better than one extra monthly payment?
They are nearly identical — 26 halves equals 13 payments, same as adding 1/12 to each monthly payment. Choose whichever you will actually stick to.
Do lenders charge for biweekly programs?
Many third-party processors do ($300-$500+ setup plus per-payment fees). Your lender may offer it free, or you can replicate the effect yourself at zero cost.
Can I switch back to monthly later?
Yes — biweekly is a payment schedule, not a contract. Just resume normal monthly payments; the extra principal you already paid keeps working for you.
Does this work for other loans?
The same 13th-payment effect accelerates any amortizing loan: auto, student, personal. The higher the rate, the bigger the savings.
