Prepayment penalty: what it is and how to check yours

By Sergio Ruiz · Last reviewed: October 8, 2026 · Covers U.S. rules

The short answer

A prepayment penalty is a fee some lenders charge if you pay off all or part of a loan early. Not every loan has one. On mortgages it usually applies when you pay off the full balance within the first few years; small extra principal payments do not normally trigger it. The only way to know is to check your own loan documents.

When does a prepayment penalty apply?

Mortgages. The Consumer Financial Protection Bureau (CFPB) explains that a mortgage penalty usually applies when you pay off the full balance, for example when you sell or refinance, within a set window that is commonly three or five years. A penalty could also apply in some cases if you pay off a large portion of the mortgage at once. Penalties “do not normally apply if you pay extra principal on your mortgage in small chunks at a time,” but the CFPB recommends confirming with your lender.

Car loans. The CFPB says your contract and state law determine whether you can pay off an auto loan early, and some states ban prepayment penalties for certain loans.

Federal limits on many U.S. mortgages

For loans covered by the federal rule in 12 CFR 1026.43(g) (part of Regulation Z), a prepayment penalty is allowed only if the loan meets all of these conditions:

its annual percentage rate cannot increase after closing,
it is a qualified mortgage, and
it is not a higher-priced mortgage loan.

Even then, the penalty must not apply after the three-year period following closing. It is capped at 2 percent of the outstanding balance prepaid if incurred during the first two years, and 1 percent during the third year. A lender also must not offer such a loan with a prepayment penalty unless it also offers an alternative without one. These limits depend on the type of loan, so they do not replace reading your own contract.

How to check whether you have one

Read your loan documents. You agreed to any prepayment penalty when you closed, so it is in the paperwork. Look for the words “prepayment” or “prepay” and read the exact conditions and amount.
For a car loan, read your contract and your Truth in Lending disclosures, and check whether your state prohibits penalties on your type of loan.
Ask your lender or servicer in writing: whether there is a penalty, what triggers it, how it is calculated, and when it ends.
If you are shopping for a loan, the CFPB suggests asking for a quote on a similar loan without a prepayment penalty so you can compare the total cost.

What a penalty could cost compared with what a payment can save

If you do have a penalty, compare it with the interest you would avoid. This example uses a new $300,000, 30-year mortgage at 6.5%, a one-time extra payment in the second year, and the federal cap of 2 percent as the worst case.

One-time payment in year 2	Highest penalty at 2%	Interest saved	Time saved
$20,000	$400	$91,107	4 yr 10 mo
$50,000	$1,000	$180,964	10 yr 1 mo
$100,000	$2,000	$269,077	16 yr 2 mo

Assumptions: $300,000 loan, 6.5% fixed rate, 30 years, one-time payment applied to principal in month 13. The penalty column is the most the federal cap would allow, not what your loan charges. Many loans have no penalty at all, and many penalties are smaller or end sooner. Method: How the calculator works.

The takeaway is not that you should ignore a penalty. It is that a penalty is a known, one-time cost, while the interest you avoid keeps growing for the rest of the loan, so it is worth running the numbers before you decide. If your penalty window ends soon, waiting may also be an option.
