Half your monthly payment, every 2 weeks. That's 26 half-payments a year — 13 full payments instead of 12. See exactly how much faster that hidden extra payment gets you debt-free.

Because a year has 52 weeks and there are 26 biweekly periods, you end up making 26 half-payments, which equals 13 full monthly payments instead of the 12 a standard monthly schedule produces. That one extra payment each year goes entirely to principal, shrinking the balance that interest is charged against every month that follows.
On a 30-year mortgage at 6% with a $2,000 monthly payment, switching to biweekly cuts roughly four and a half years off the loan and saves about $60,000 in interest. On a five-year auto loan, the same switch saves around six months and several hundred dollars. On a credit card, the savings depend entirely on whether you actually hold the extra payment as principal or treat it as a prepayment of next month's bill.
Interest on amortizing debt is calculated on the outstanding balance. The higher the balance at the start of a billing period, the more interest accrues. An extra principal payment early in the loan reduces every subsequent month's interest, not just the month it was paid. That is why a single extra payment in year one saves more interest than a single extra payment in year twenty on the same loan.
Over the life of a long mortgage, one extra payment per year compounds aggressively. You are not just skipping one month's interest. You are shortening the tail of the loan, which is where payments are most principal-heavy anyway. The effect is an accelerated march toward the payoff date without any change to your monthly cash flow beyond finding one extra payment inside the calendar.
Not every lender processes biweekly payments the way borrowers assume. Some hold each half-payment in an escrow-style suspense account until the full monthly amount is received, then apply it as a single monthly payment. That defeats the mechanism. No principal is paid early, no interest is saved, and the borrower thinks they are accelerating while the schedule runs exactly as before.
Other lenders charge setup fees or monthly fees to convert a loan to a biweekly schedule, sometimes hundreds of dollars up front. Those fees often eat the first year or two of savings. The workaround is simple: keep the standard monthly schedule and make one extra principal payment each year on your own, which produces identical results without fees.
On credit cards, biweekly payments only help if you are actually reducing the balance. Credit cards calculate interest on average daily balance, so paying half the bill on the 10th and the other half on the 24th does lower average balance versus paying the full amount on the 28th. But if you are running new charges in between, those offset the benefit completely.
Method one is the lender-managed version. You enroll in a biweekly program, the lender pulls half your payment every two weeks, and the system produces the extra payment automatically on the two pay periods per year when three biweekly pulls fall inside one month. Simple, hands-off, and useful only if the lender actually applies payments as received.
Method two is the self-managed version. Keep your standard monthly payment. Once a year, when you have three pay periods in a month or when a tax refund lands, make one additional payment equal to your regular monthly payment, marked as principal-only. The effect is identical to a true biweekly schedule, costs nothing to set up, and works with any lender. For anyone without a mortgage biweekly option, this is the right play.
Biweekly works well if you are paid every two weeks, because each half-payment falls naturally in line with a paycheck. It is awkward if you are paid monthly or semi-monthly, because you end up setting aside half a month's payment out of sequence. If forcing biweekly creates strain that risks a missed payment, the self-managed annual extra payment is a better choice. The goal is an extra principal payment per year, not a specific schedule. The schedule is just the mechanism.
