How to Use a Biweekly Mortgage Calculator to Save Thousands
Learn how biweekly mortgage payments work and use our free calculator to see exactly how much you can save on your mortgage.
Making biweekly mortgage payments is one of the simplest ways to pay off your home loan faster and save thousands in interest. Here's how it works — and how our free calculator can show you exactly what you'll save.
How Biweekly Payments Work
Instead of making 12 monthly payments per year, you make half your monthly payment every two weeks. Since there are 52 weeks in a year, you end up making 26 half-payments — which equals 13 full payments instead of 12.
That one extra payment goes directly toward your principal balance, which:
- Reduces your loan balance faster
- Saves you interest on the remaining balance
- Shortens your loan term by several years
Example: $300,000 Mortgage at 6.5% for 30 Years
| Payment Method | Monthly | Biweekly Accelerated |
|---|---|---|
| Payment Amount | $1,896 | $948 (×26 = 13/yr) |
| Total Interest | $382,632 | ~$280,000 |
| Payoff Time | 30 years | ~24 years |
| Interest Saved | — | ~$102,632 |
