Key Insight
Bi-weekly payments = 13 monthly payments per year vs 12 — one extra payment annually with no lifestyle change. You simply pay half your monthly amount every two weeks instead.
Confirm your lender accepts bi-weekly payments and applies them immediately — some hold funds until a full month accumulates.
Bi-Weekly Mortgage Calculator simulates 26 bi-weekly half-payments per year (equivalent to 13 monthly payments) versus 12 monthly payments, tracking balance month-by-month to show years saved and total interest saved.
By paying half your monthly mortgage payment every two weeks (26 half-payments/year vs. 12 full payments), you make the equivalent of one extra payment annually — shaving years off your loan and saving tens of thousands in interest with no lifestyle change.

Monthly payment = standard PMT formula. Bi-weekly payment = monthly PMT / 2; 26 payments/year. Simulation runs period-by-period using the bi-weekly interest rate (annual rate / 26) until the balance reaches zero. Monthly simulation runs month-by-month for the full term. Both track remaining balance year-by-year for the comparison table.
With bi-weekly payments you make 26 half-payments per year, which equals 13 full monthly payments instead of 12. That extra payment goes entirely to principal, reducing your balance faster and saving interest.
On a typical 30-year mortgage at 7%, switching to bi-weekly payments saves about 4–5 years and tens of thousands in interest. Your exact savings depend on your rate and balance.
Most lenders accept bi-weekly payments, but some may not apply the extra payment directly to principal without explicit instruction. Verify with your servicer — or simply make one extra principal payment per year, which achieves the same result.
They are mathematically equivalent if the extra amount is the same. Bi-weekly just spreads the extra across 26 periods, which can feel more manageable and aligns naturally with bi-weekly paychecks.
