Biweekly Mortgage Payments in 2027: How Much Do They Actually Save?

With a standard monthly mortgage, you make 12 payments per year. With a biweekly payment schedule, you pay half your monthly payment every two weeks — resulting in 26 half-payments, or the equivalent of 13 full monthly payments per year. The extra payment goes entirely to principal, reducing your balance faster and cutting total interest. On a $400,000 mortgage at 7% over 30 years, switching to true biweekly payments saves approximately $60,000–$80,000 in interest and shaves 4–5 years off the loan. See CFPB — Biweekly mortgage payment programs.

In Canada, lenders offer two biweekly options: (1) Regular biweekly: monthly payment ÷ 2, paid every two weeks — equivalent to 12 monthly payments per year; (2) Accelerated biweekly: annual payment ÷ 26, resulting in one extra monthly payment per year — equivalent to 13 monthly payments per year. The accelerated option is more powerful. On a $500,000 CAD mortgage at 5.5% over 25 years, accelerated biweekly saves approximately $35,000–$50,000 CAD in interest and reduces amortization by 2–3 years. CMHC-insured mortgages with accelerated payments reduce total cost significantly. See CMHC — Mortgage payment options.

Direct lender biweekly programs (set up through your bank or mortgage servicer) are typically free. However, third-party biweekly payment programs charge setup fees of $300–$500 plus monthly fees of $5–$15 — these are unnecessary if you can set up biweekly payments directly with your lender. Beware of third-party "biweekly mortgage acceleration" companies — they collect your biweekly payments but only remit funds to your lender monthly, meaning you pay fees for no actual benefit. Always set up biweekly payments directly with your mortgage servicer. In Canada, all major banks (TD, RBC, BMO, Scotiabank, CIBC) offer accelerated biweekly at no extra cost. See CFPB — Biweekly payment program pros and cons.

Most conventional, FHA, VA, and USDA mortgages allow biweekly payment arrangements, but you should confirm with your servicer. Key requirements: (1) No prepayment penalty — some older mortgages have prepayment penalties that could apply if the extra payments exceed a threshold; (2) Servicer flexibility — some servicers only accept monthly payments and apply biweekly funds to a holding account, not directly to principal; (3) Loan type — HELOCs may already allow flexible payment schedules. In Canada, closed mortgages may have prepayment limits (e.g., 20% of original principal per year) — accelerated biweekly payments count toward this limit. Open mortgages have no restrictions. See prepayment penalty glossary.

The mathematical outcome is nearly identical — both strategies result in 13 monthly payments per year applied to your loan. The difference is cash flow management: biweekly payments spread the extra cost across the year, making it easier to budget compared to a lump-sum 13th payment. If your lender does not offer a true biweekly program, you can replicate the effect by dividing your monthly payment by 12 and adding that amount to each monthly payment. For example, on a $2,000/month payment, adding $167 each month achieves approximately the same payoff acceleration. Use the mortgage calculator to model your specific savings scenario.
