Biweekly Payment Calculator

There are 52 weeks per year, so paying every 2 weeks means 26 biweekly payments. Each biweekly payment is half your monthly payment, so 26 × ½ = 13 full monthly payments per year — one more than the 12 you'd make on a normal monthly schedule. That extra payment goes entirely to principal, which compounds the savings every future month.

Maybe — and this is the load-bearing question. Some servicers immediately apply biweekly payments, which captures all of the savings. Others hold the half-payment and apply both halves on the monthly due date, which captures none of the savings. Call your servicer or check the auto-pay settings to confirm before relying on biweekly math.

Yes — make one extra full monthly payment per year, applied 100% to principal. Mathematically it's nearly identical to the biweekly strategy and most servicers honor explicit principal-only requests. Many borrowers prefer this because it's simpler and avoids the servicer-application risk.

It saves more in absolute dollars on high-rate loans because every dollar of principal you knock off avoids more accrued interest. On low-rate federal subsidized loans (under 5%), the savings are real but smaller. On high-rate private or PLUS loans (7%+), biweekly can save thousands.

Absolutely — they're fully complementary strategies. Refinancing cuts your rate (saving interest by reducing what accrues per dollar of balance), while biweekly cuts your term (saving interest by reducing how many months balance accrues). Stacking them gives you the largest possible savings.

No — and this is a critical exception. If you're on the path to PSLF or income-driven forgiveness, the leftover balance gets discharged anyway. Paying extra (whether biweekly or otherwise) just reduces what would have been forgiven. On a forgiveness path, pay exactly the qualifying minimum and invest or save anything extra.
