Frequently asked questions

How does this loan calculator work?

Enter the loan amount, the annual interest rate and the term. AmortiGo calculates your monthly payment and builds the full amortization schedule, showing how much of each payment goes to principal and to interest.

What happens when I make extra payments to principal?

Every extra payment goes entirely to the loan balance, so the next interest charges are calculated on a smaller amount. You can add a recurring extra amount, one-time extras, or both, and the calculator shows the interest you could save.

Is it better to reduce the loan term or the monthly payment?

Keeping the same payment shortens the loan and usually saves more interest. Recalculating the payment lowers your monthly cost and keeps the original end date. AmortiGo compares both side by side so you can see the difference.

Is AmortiGo free, and is my data sent anywhere?

It is free. All calculations run in your browser, and the figures you enter are not sent to any server. Results are estimates; your lender's numbers may differ.
