Biweekly Mortgage Calculator — Payoff Time Saved

The biweekly plan works through arithmetic rather than any change in the interest rate. Half the standard monthly payment remitted every 14 days produces 26 half-payments a year, which equals 13 monthly payments instead of 12. That thirteenth payment lands entirely on principal, and every dollar of principal retired early removes all future interest that dollar would have carried. On a 300,000 dollar loan at 6.5 percent for 30 years the monthly principal and interest is about 1,896.20 dollars, so the biweekly amount is 948.10 dollars and the extra contribution is roughly 1,896 dollars a year. That cuts the payoff from 360 months to roughly 24 years and saves on the order of 88,000 dollars in interest. Two mechanisms drive the saving, and they are not equal in size. The extra annual payment does nearly all the work; the slightly earlier arrival of each half-payment contributes only a small additional amount. The savings scale with the rate and with the term, because a longer, costlier loan devotes more of each early payment to interest - about 86 percent of the first payment on a 30-year loan at 6.5 percent versus roughly 62 percent on a 15-year loan at the same rate. The critical caveat is servicer handling. Many servicers hold each half-payment in suspense and disburse a single monthly payment, which eliminates the timing benefit, and third-party biweekly conversion services often charge 200 to 400 dollars in setup fees plus recurring charges for a result you can replicate free by adding one-twelfth of the payment to each monthly check, marked as principal only.

Biweekly mortgage plans emerged in North America in the early 1980s, when double-digit mortgage rates made any interest reduction attractive and when employers were shifting large numbers of workers onto biweekly payroll cycles, so a payment every other Friday matched how households actually received money. Canadian lenders offered accelerated biweekly and weekly options widely, and US savings institutions and mortgage bankers followed. Because the plans required no change to the note rate and no refinance, they spread as a servicing feature rather than a new loan product. A sizable third-party industry grew up around the idea during the 1990s, marketing enrollment in equity acceleration programs by direct mail. Regulators and consumer agencies responded to complaints that the fees purchased nothing the borrower could not do alone, and that some firms held funds rather than remitting them promptly. State attorneys general brought enforcement actions during the 1990s and 2000s, and the Consumer Financial Protection Bureau, created by the Dodd-Frank Act of 2010, has since published guidance warning consumers about paid biweekly conversion services and reminding servicers that extra funds must be applied as the borrower directs. The Dodd-Frank qualified mortgage rules that took effect in January 2014 also barred prepayment penalties on most new residential loans, which removed the last common obstacle to accelerating payoff.
