How much do I save by paying off a loan early?

The savings depend on your remaining balance, interest rate, and how much extra you pay. In general, the earlier you start making extra payments, the more you save because you reduce the principal that future interest is calculated on. For a $20,000 loan at 6% with 5 years remaining, paying an extra $100/month saves about $1,200 in interest and pays off the loan 14 months early.

About This Analysis

This calculator provides estimates based on the inputs you supply. It assumes extra payments are applied to principal each month and uses standard amortization with a fixed interest rate. It does not account for prepayment penalties, which some loans may include. Actual payoff dates depend on payment timing and lender processing. Results are for informational and educational purposes only and should not be considered financial advice.
