Why Biweekly Payments Make Such a Big Difference
With a standard mortgage, you make 12 monthly payments per year. With a biweekly schedule, you split your monthly payment in half and pay every two weeks—which adds up to 13 full payments per year instead of 12.
Here’s why that matters:
- 📅 13 Payments Instead of 12 — 26 half-payments = 13 full payments annually
- ⚡ Accelerate Your Equity — the extra payment goes 100% toward your principal
- 💸 Massive Interest Savings — shave 4–6 years off a 30-year mortgage and save thousands
- 🔒 Aligns With Your Paycheck — perfect if you’re paid biweekly
- 🌍 170+ Currencies Supported — all amounts in your local currency
- 🔒 100% Private — everything runs locally, nothing is stored
The Math Behind It (Made Simple)
Your Standard Monthly Payment
We calculate this using your loan amount, interest rate, and term—just like any other mortgage.
Your Biweekly Payment
Biweekly Payment = Your standard monthly payment ÷ 2
The Magic of the Extra Payment
Since there are 52 weeks in a year, you make 26 biweekly payments—which equals 13 full monthly payments every 12 months. That extra payment goes straight to principal, not interest.
See the Difference: Real-World Example
Take a $350,000 mortgage at 6.5% interest over 30 years:
| Payment Schedule | Monthly Payment | Annual Total | Payoff Time | Total Interest | Interest Saved |
|---|---|---|---|---|---|
| Standard Monthly | $2,212.24 | $26,546.88 | 30.0 Years | $446,406 | $0 |
| Biweekly | $1,106.12 (every 2 wks) | $28,759.12 | 24.5 Years | $360,820 | +$85,586 |
That’s 5.5 years off your mortgage and over $85,000 back in your pocket—just by changing your payment frequency.
How to Make Biweekly Payments Work for You
- Check with your servicer — confirm if they offer automated biweekly processing (and whether there’s a fee).
- DIY alternative — if your servicer charges a fee, just divide your monthly P&I payment by 12 and add that extra amount to your regular monthly payment. Same result, no fee.
- Verify extra principal crediting — ensure your lender applies extra payments to principal, not prepaid interest.
- Start anytime — you don’t need to wait for a refinance to switch to biweekly.

Common Questions About Biweekly Mortgage Payments
How does a biweekly mortgage payment schedule work?
Instead of 12 full monthly payments per year, you pay half your monthly payment every two weeks. With 52 weeks in a year, that’s 26 half-payments—which equals 13 full monthly payments. The “extra” 13th payment goes straight to principal.
How much time and interest can I save?
On a $350,000 30-year mortgage at 6.5%, biweekly payments shorten your term from 30 to about 24.5 years—saving over $85,000 in interest. The exact numbers depend on your loan size, rate, and remaining term.
Should I pay my lender a fee for a biweekly program?
No. Avoid setup fees or monthly administration fees. You can achieve the exact same result for free by sending 1/12th of your monthly principal and interest payment as an extra principal payment each month.
What’s the difference between bimonthly and biweekly?
- Bimonthly = twice a month (24 payments/year = 12 full payments)
- Biweekly = every two weeks (26 payments/year = 13 full payments)
Only a true biweekly schedule gives you that extra 13th payment each year.
Is my financial data secure?
Absolutely. All calculations run entirely in your browser. No mortgage balances, rates, or financial details are ever stored or transmitted. Your home loan planning stays between you and your screen.
🏠 Quick Tip: Even if you can’t commit to full biweekly payments, adding just a little extra to your regular monthly payment can make a meaningful difference over time. Every extra dollar toward principal is a dollar you don’t pay interest on.
