The short answer
Yes, and on almost every mortgage written today it costs nothing extra to do it: you can add to principal each month, send a lump sum, pay biweekly, recast or refinance to a shorter term, and the only thing to check first is whether your own note carries a prepayment penalty, which federal rules have made rare.
Two questions hide inside this one. The first is mechanical and has a clean answer: yes, and the servicer has to apply the money. The second is whether it is worth doing, and that has no general answer, because it compares a rate you are certain of against a return you are not.
The five ways to get ahead of the schedule
They are not five different results. Every one puts money against principal sooner than the amortization schedule asks for, deleting the future interest that principal would have earned. What changes is how the money arrives and whether the payment moves.
- Extra principal with the monthly payment. The common version, and the one needing the least paperwork. It shortens the term, it does not lower the payment.
- Biweekly payments. Half the payment every two weeks is 26 halves a year, which is 13 monthly payments rather than 12. The gain is that thirteenth payment.
- A lump sum against principal: a bonus, a tax refund, proceeds from something sold. The same effect in one piece.
- A recast. A lump sum to principal, after which the servicer re-amortizes the balance over the remaining term, lowering the payment while keeping the payoff date. Fees run a few hundred dollars, servicers set a minimum reduction, and government loans generally do not allow it.
- A refinance into a shorter term. A 15-year loan forces the faster schedule and usually carries a lower rate, at the cost of closing costs and a payment you can no longer skip.
What $200 a month does to a $350,000 loan
At 6.5 percent over 30 years, the payment calculator's default rate, a $350,000 loan has a principal and interest payment of about $2,212 and pays roughly $446,000 in interest over the term. Add $200 a month from the first payment and the loan is gone in about 286 months instead of 360: six years and two months early, and about $108,000 of interest never charged.
The biweekly version lands close, because a thirteenth payment here is about $184 a month spread out: roughly five years and ten months early, about $102,000 saved. A single $10,000 lump sum in year five, and nothing else, still takes 21 months and $38,000 off. Early money does more than late money, because it deletes interest across the whole remaining term. Change the rate and every figure moves, so run your own balance through the calculator.
Prepayment penalties, and the few places they still live
FHA, VA and USDA loans cannot carry a prepayment penalty, and the standard note the agencies buy does not have one, which covers most conforming loans. Regulation Z narrowed the rest: under 12 CFR 1026.43(g) a consumer mortgage may carry a penalty only if it is a fixed-rate qualified mortgage that is not higher-priced, capped at 2 percent of the amount prepaid in the first two years and 1 percent in the third, and never after three years.
The gaps matter. Older loans predate the rule, and business-purpose loans, which is how many rental-property and portfolio loans are written, are not covered transactions and can carry a penalty of their own design. Your note settles it, under a heading like Borrower's Right to Prepay.
What the should question actually turns on
One side is arithmetic. Paying down a loan at 6.5 percent is a certain, tax-free return of 6.5 percent, and little else in a household budget is that certain. The other side is that the money is then locked in the house: getting it back means selling, refinancing or a home equity line, all of which cost money and time and none of which are guaranteed to be there when you need them.
Against that sit the alternatives: a retirement account with an employer match, an investment returning more than the rate over the long run, or higher-rate debt. The mortgage interest deduction lowers the effective rate for owners who itemize, which most no longer do since the standard deduction rose, so a tax preparer is the one to say whether it applies. The framing is a comparison, not a verdict, and nothing here is investment or tax advice.
Questions people ask
Does paying extra on a mortgage lower the monthly payment?
No. Extra principal shortens the loan rather than shrinking the payment, so you owe the same amount each month for fewer months. The one way a lump sum lowers a payment is a recast, where the servicer re-amortizes the balance over the remaining term.
Do you have to tell the servicer to apply extra money to principal?
Usually yes. An unlabelled overpayment is often held as a partial payment or applied to next month's bill, which shortens nothing. Most servicers have a principal-only field online, and a cheque should say so on it.
Is a biweekly mortgage plan worth paying a fee for?
The result comes from making 13 monthly payments a year, which anyone can do for nothing by dividing one payment by twelve and adding it each month. A third-party plan charging a setup or transaction fee is selling a schedule you can set yourself.
