How do biweekly payments help?

There are 52 weeks in a year, so paying half your monthly amount every two weeks makes 26 half-payments = 13 full payments instead of 12. That extra payment goes to principal and shortens your payoff.

How do I model biweekly payments here?

Approximate it by adding one-twelfth of a monthly payment to the "extra payment" field — that equals the 13th payment spread across the year. The interest-saved figure updates instantly.

Do all lenders accept biweekly payments?

Many do, but some hold partial payments until a full one arrives, or charge setup fees. You can get the same benefit for free by paying a little extra each month yourself.

The biweekly trick

A year has 26 two-week periods. Pay half your normal monthly payment every two weeks and you make 13 monthly payments' worth in a year instead of 12 — a free extra payment, straight to principal.

Model it above

To estimate the effect, add roughly 1/12 of your monthly payment to the extra-payment field. For a cleaner picture of the lever, see the extra payment calculator. Just don't pay a third party a fee to "set up" biweekly payments — you can do it yourself for nothing.
