Process & terms

Does partial prepayment save interest on personal loans?

Short answer

Yes. Every dollar of extra principal payment reduces all future interest accrual on the loan. Even small extra payments ($25-50/month) can knock months off the payoff timeline and save hundreds in total interest over the loan's life.

Context

Specific example: a $15,000 loan at 14% APR over 48 months has a $410/month payment and $4,672 total interest. Adding $50/month to principal cuts the payoff to 42 months and total interest to $4,072, $600 saved.

The larger the loan and the higher the APR, the more impact extra payments have. For high-APR loans (above 20%), aggressive prepayment from any windfalls (tax refunds, bonuses, side income) is usually a higher-return move than investing the same dollars.
