How to Make Bi-Weekly Mortgage Payments
Understanding Bi-Weekly Payments
Bi-weekly mortgage payments involve making payments every two weeks instead of monthly. Since there are 52 weeks in a year, you make 26 bi-weekly payments, which equals 13 monthly payments instead of the standard 12.
Standard vs Accelerated Bi-Weekly
- •Standard: Half monthly payment 24 times (same annual amount)
- •Accelerated: Half monthly payment 26 times (extra payment annually)
Why It Saves Money
Amortization Effect
More frequent payments reduce principal faster, decreasing interest accrual
Extra Annual Payment
26 bi-weekly payments = 13 monthly payments per year
Compound Savings
Lower principal means less interest charges over time
Important Considerations
- • Check with your lender about bi-weekly payment options
- • Some lenders charge fees for bi-weekly payment plans
- • Consider making extra principal payments instead
- • Ensure your budget can handle the increased payment frequency
