Monthly, Biweekly, Accelerated: Does Payment Frequency Actually Matter?

Regular biweekly payments simply divide your monthly payment amount and collect it every two weeks (26 times a year) instead of once a month — the total paid annually is the same as monthly, just distributed differently. It doesn't accelerate your payoff.

Accelerated biweekly sets your payment to exactly half your monthly payment, but collects it 26 times a year — which works out to the equivalent of one extra full monthly payment annually, compared to true monthly or regular biweekly. That extra payment goes straight to principal, which is what shortens your amortization and reduces total interest.

Weekly and accelerated weekly follow the same logic at a finer frequency — accelerated weekly also adds the equivalent of one extra monthly payment per year, just spread across 52 payments instead of 26.

If your goal is paying off your mortgage faster, accelerated biweekly (or accelerated weekly) is the frequency that actually does it — regular biweekly or weekly are purely a cash-flow timing preference with no payoff-speed benefit.
