Bi-Weekly Mortgage Payment Calculator
Compare bi-weekly mortgage payments to standard monthly payments to see how much time and interest you could save.
How bi-weekly payments save money
Paying half your monthly mortgage payment every two weeks results in 26 half-payments per year — the equivalent of 13 full monthly payments instead of 12. That extra payment each year goes entirely toward principal, shortening your loan term and reducing total interest.
How it works
The calculator first computes your standard monthly payment using the amortization formula, then simulates paying half that amount every two weeks (accruing interest at the equivalent bi-weekly rate) until the balance reaches zero, tracking how much sooner the loan is paid off and how much interest is saved.
This tool is for general educational and planning purposes. Not all lenders offer true bi-weekly payment programs, and some charge fees for them — check with your loan servicer before switching.
