What counts as extra principal?
An additional amount paid toward your loan balance beyond your scheduled principal and interest payment. Ask your loan servicer how to designate it correctly.
Why does it save interest?
Reducing principal sooner can lower the interest charged over the remaining loan term. The effect depends on your balance, rate, payment amount, and timing.
What should you check?
Confirm any prepayment penalty, loan terms, and servicer instructions. This tool assumes a fixed rate and that extra payments reduce principal as intended.
