Questions People Ask

What is an amortization schedule?

A payment-by-payment table showing how much of each payment goes to interest and how much to the loan itself, and the balance left after each one.

How do extra payments help?

Extra money paid toward principal lowers the balance sooner, so less interest builds up. Even small extra payments can take months or years off a long loan.

Is my loan information saved anywhere?

No. The calculator runs in your browser and nothing is sent to us. To keep your numbers, export the CSV and load it next time.
