About Biweekly Payments

Making biweekly payments can reduce interest and shorten the loan term because you make the equivalent of one extra monthly payment per year.

Example: $300k, 6.5% APR, 30 years — biweekly schedule will pay off earlier and save interest.

More frequent payments reduce principal faster, lowering interest accrual.

This is a theoretical schedule; confirm with your lender for timing.
