Prepayment Penalty
A fee charged by a lender when you pay off a loan earlier than the agreed repayment schedule.
Legal Definition
A prepayment penalty is a fee charged by a lender when a borrower repays a loan before the scheduled maturity date or pays off more than a specified portion of the principal in a given period. Prepayment penalties are designed to compensate lenders for the loss of expected interest income that results from early repayment. They are most common in mortgages, auto loans, and some personal and business loans. The penalty may be structured as a flat fee, a percentage of the remaining balance, a declining fee (higher in early years, phasing out), or a yield-maintenance formula calculating the present value of lost future interest.
In Plain English
A prepayment penalty means the lender charges you money for paying them back ahead of schedule. Lenders profit from the interest you pay over the loan term — if you pay early, they lose that income. The penalty compensates for that loss. Before paying off a loan early or refinancing (which effectively pays off the original loan), check your agreement for a prepayment clause. If the penalty exceeds your projected interest savings, early payoff is financially harmful. Many consumer loans — especially after recent regulatory changes — have no prepayment penalty. Federal rules limit prepayment penalties on most residential mortgages to the first three years.
Real-World Example
Emma has a 5-year personal loan with a prepayment penalty of 2% of the remaining balance. After 2 years, she has $15,000 remaining and wants to pay it off to save on interest. The prepayment penalty is $300 (2% × $15,000). She calculates that paying off the loan now saves $1,400 in future interest. The savings ($1,400) exceed the penalty ($300), so paying off early still makes financial sense. If the penalty had been 10% ($1,500), paying early would have cost her more than she saved.
