Enter loan amount, interest rate, and term to see biweekly payment amount, equivalent monthly cost, and estimated interest savings from paying half your payment every two weeks.

How to use this tool

Enter loan amount, annual interest rate, and term in years. Calculate to see monthly vs biweekly payment amounts, payoff timelines, and interest saved under a true 26-payment-per-year model.

Worked example

Example: a $300,000 loan at 6.5% over 30 years has about a $1,896 monthly payment. Paying $948 biweekly (26 applications per year) can shave several years off payoff and save tens of thousands in interest versus monthly scheduling.

How it works

Compares a standard monthly mortgage payment with true biweekly payments: half the monthly amount applied every two weeks (26 times per year), with interest accruing at the annual rate divided by 26. That schedule is equivalent to about one extra full monthly payment each year, which accelerates principal reduction. This is not a lender holdback model that banks half-payments until a full monthly installment posts.
