How does biweekly mortgage payment work?
Biweekly payments mean you pay half the monthly amount every 2 weeks, resulting in 26 payments per year.
This adds one full extra payment annually, reducing both interest and loan term.
💡 Example Scenario
Let’s say:
- Loan Amount: $300,000
- Interest Rate: 5%
- Loan Term: 30 years
With biweekly payments, you could save tens of thousands in interest and pay off your loan years earlier.
