How It Works

Our Biweekly Mortgage Calculator demonstrates the significant savings you can achieve by making biweekly mortgage payments instead of monthly. By making an extra payment each year, you can shave years off your loan term and save tens of thousands in interest, especially crucial with projected 2026 interest rates. Discover how this simple change can accelerate your path to homeownership.

This calculator works by taking your standard monthly payment and dividing it by two to determine your biweekly payment amount. Since there are 26 biweekly periods in a year, you effectively make 13 monthly payments annually instead of 12. The extra payment directly reduces your principal balance, leading to compounding interest savings over the life of the loan.

Be aware that some lenders charge a fee for biweekly payment plans, so always confirm with your mortgage provider. Ensure your biweekly payments are truly applied every two weeks, not just monthly payments split in half. A common mistake is not considering the full impact of early principal reduction on total interest paid.

Example: $350,000 Mortgage at 6.8% in 2026

  1. 1 Imagine you take out a $350,000 mortgage at 6.8% interest (a realistic 2026 rate) over 30 years. Your standard monthly payment would be approximately $2,284.
  2. 2 By switching to biweekly payments, you'd pay $1,142 every two weeks. This results in 26 payments a year, effectively making one extra full monthly payment annually.
  3. 3 Instead of paying off your mortgage in 30 years, you could pay it off in approximately 26 years and 2 months. This change would save you over $45,000 in total interest paid.
  4. 4 This example highlights how a seemingly small adjustment in payment frequency can lead to substantial financial benefits, freeing up significant capital years sooner.

Frequently Asked Questions

How much do biweekly mortgage payments save?
Biweekly payments make 26 half-payments per year, equaling 13 full monthly payments instead of 12. On a $350,000 30-year mortgage at 6.5%, this saves approximately $52,000 in interest and pays off the loan about 4.5 years early.
Can I just make one extra mortgage payment per year instead?
Yes. Making one extra principal-only payment per year achieves nearly the same result as biweekly payments. You can also add 1/12 of your monthly payment to each month. Both methods effectively make 13 payments per year.
Does my lender offer biweekly payments?
Some lenders offer official biweekly programs, but beware of fees. Many third-party services charge setup and processing fees. The simplest free approach is to make extra principal payments yourself, either monthly or annually.
