Save Thousands with Bi-Weekly Mortgage Payments
Learn how switching to bi-weekly payments can help you pay off your mortgage years faster and save tens of thousands in interest
For most homeowners, a mortgage is the largest debt they'll ever carry. While the standard 30-year mortgage offers manageable monthly payments, it comes with a hefty price tag in interest over the life of the loan. Fortunately, there's a simple strategy that can shave years off your mortgage and save you thousands: bi-weekly payments.
In this comprehensive guide, we'll explore how bi-weekly mortgage payments work, the substantial savings they can generate, and how to use our Bi-Weekly Mortgage Calculator to see exactly how much you could save.
What Are Bi-Weekly Mortgage Payments?
Bi-Weekly Mortgage Payments Explained
Bi-weekly mortgage payments involve paying half of your monthly mortgage amount every two weeks instead of one full payment each month. Since there are 52 weeks in a year, this results in 26 half-payments, which equals 13 full monthly payments per year instead of the usual 12.
This simple change creates an extra payment each year, which goes directly toward reducing your principal balance and saving you interest over the life of the loan.

How Bi-Weekly Payments Work
The Math Behind Bi-Weekly Payments
- Standard Monthly Payment: One full payment each month (12 payments/year)
- Bi-Weekly Payment: Half the monthly amount paid every two weeks (26 half-payments/year)
- The Result: 26 half-payments = 13 full payments per year
Key Benefits of Bi-Weekly Payments
Pay Off Loan Faster
A typical 30-year mortgage can be paid off in approximately 24-26 years with bi-weekly payments, saving you 4-6 years of payments.
Save Thousands in Interest
By reducing your principal faster, you pay less interest over the life of the loan, potentially saving tens of thousands of dollars.
Budget-Friendly
Smaller, more frequent payments can be easier to manage than one large monthly payment, especially if you're paid bi-weekly.
How the Bi-Weekly Mortgage Calculator Works
Input Fields
Our calculator uses the following inputs to determine your potential savings:
- Loan Amount: The original principal balance of your mortgage
- Interest Rate: Your annual mortgage interest rate
- Loan Term: The original length of your mortgage (typically 15, 20, or 30 years)
- Start Date: When your first payment is due
Calculation Outputs
The calculator provides comprehensive results showing the benefits of bi-weekly payments:
- Bi-Weekly Payment Amount: Half of your monthly payment
- Total Interest Saved: How much less interest you'll pay compared to monthly payments
- Loan Payoff Date: When your mortgage will be fully paid off
- Time Saved: How many years and months you'll shave off your mortgage term
Pro Tip: Align with Your Paycheck
If you're paid bi-weekly, switching to bi-weekly mortgage payments can make budgeting easier since you're making mortgage payments when you receive your paycheck.
The Math Behind the Savings
Step 1: Compute Monthly Payment
The calculator first determines your standard monthly payment using the standard mortgage formula:
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where:
- M = Monthly payment
- P = Loan principal amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (loan term in years × 12)
Step 2: Convert to Bi-Weekly
- Bi-Weekly Payment = M ÷ 2 (half the monthly amount)
- 26 Bi-Weekly Payments = 13 Full Payments/Year (vs. 12 monthly)
Step 3: Calculate Interest Savings
The extra payment each year reduces your principal balance faster, which means less interest accrues over time. The calculator simulates this accelerated payoff schedule to determine your exact savings.
Example Calculation
Let's look at a typical example to illustrate the potential savings:
| Loan Details | Monthly Payments | Bi-Weekly Payments |
|---|---|---|
| Loan Amount | $300,000 | $300,000 |
| Interest Rate | 4% | 4% |
| Loan Term | 30 years | ~25.5 years |
| Payment Amount | $1,432/month | $716 every 2 weeks |
| Total Interest Paid | $215,609 | $187,221 |
| Total Savings | — | $28,388 |
As this example shows, switching to bi-weekly payments could save you over $28,000 and help you pay off your mortgage 4.5 years early!
