What is an extra loan payment calculator?

This calculator compares your normal repayment schedule with a plan that includes extra monthly, yearly or one-time principal payments. It estimates the change in payoff time and interest cost.

How extra payments work

Extra principal reduces the balance used to calculate future interest. Confirm that your lender applies extra money to principal and check for prepayment penalties.

Frequently asked questions

Do extra payments reduce interest?

Generally yes, because principal is reduced sooner.

Should I pay monthly or as a lump sum?

Earlier payments usually save more interest, but the best option depends on your cash flow.

Can lenders charge a prepayment penalty?

Some loans can. Review your agreement before paying extra.
