Frequently asked questions about the loan amortization calculator
Everything you need to know to calculate your loan's payments.
How is the monthly payment calculated?
+
It uses the standard fixed-payment loan amortization formula (French system): the payment stays the same throughout the term, but the split between interest and principal changes each month.
What is the amortization schedule?
+
It's the month-by-month breakdown of each payment: how much goes to interest, how much reduces the principal, and how much is left after each payment.
Why is more interest paid at the start than principal?
+
Because interest is calculated on the outstanding balance, which is highest at the start of the loan. As the balance goes down, each payment covers more principal and less interest.
Can I use it for any currency?
+
Yes, you can choose from the most common currencies right in the form.
Does it include bank fees?
+
No, it only calculates principal and interest based on the rate entered. Origination, arrangement or other fees aren't included since they vary by lender.
Is my data stored anywhere?
+
No, the whole calculation happens in your browser, with no connection to any server.
