About this calculator
How does biweekly mortgage payment work?+
Instead of 12 monthly payments, you make 26 half-payments per year. That equals 13 full monthly payments instead of 12 — one extra payment per year. That extra payment goes directly to principal, cutting years off your loan and saving significant interest.
How much does biweekly payments save on a 30-year mortgage?+
On a $300,000 mortgage at 6.75%, biweekly payments typically save $30,000–$40,000 in interest and shorten the payoff by 4–6 years. The savings compound because each extra payment reduces your balance, lowering future interest charges.
Can I just make one extra mortgage payment per year instead?+
Yes — making one extra monthly payment per year achieves almost identical savings as switching to biweekly. Just make sure the extra payment is applied to principal, not to next month's payment. Some lenders offer biweekly programs, but you can replicate it yourself for free.
Do all lenders accept biweekly mortgage payments?+
Not automatically. Some lenders hold partial payments until you complete a full monthly payment — meaning the timing benefit disappears. Before switching to biweekly, confirm with your servicer that they apply each half-payment when received and credit it to principal immediately. Alternatively, make one extra lump-sum principal payment per year instead.
When is biweekly payment NOT worth it?+
Biweekly payments are less beneficial if you plan to sell within 5 years (too short to accumulate meaningful savings), if your lender charges a fee to set up the program (some charge $200–$400), or if investing the extra money earns more than your mortgage rate. At 3% mortgage rates, investing likely beats prepaying.

15 vs 30-Year Mortgage
Both loans side by side at this week's Freddie Mac averages (6.58% and 5.96%) for three loan sizes — payment, total interest, and principal paid by years 5 and 10, with the amortization math shown — plus the invest-the-difference argument treated fairly.
Is Refinancing Worth It?
Closing costs divided by monthly saving is the whole decision. The formula worked with July 2026 rates, the rate drop you need to break even in 2/3/5 years, the term reset that raises your total interest at a lower rate, and what forecasters actually expect.
