Understanding Loan Terms
Principal is the original amount you borrow. Each payment reduces the principal gradually over the life of the loan.
Interest is the cost the lender charges for borrowing. With fixed-rate loans, the monthly interest decreases as the principal is paid down.
Amortization is the process of spreading loan payments over time. Early payments are interest-heavy; later payments go mostly toward principal.
Extra payments directly reduce the principal. Even small additional amounts each month can save thousands in interest and shorten the loan term significantly.

Is this loan calculator free?

How accurate are the results?
The calculator uses the standard amortization formula used by banks worldwide. Results are estimates—your actual payment may differ slightly due to fees, insurance, or rounding by your lender.
Does it support different currencies?
Yes. The math is currency-independent. Enter amounts in any currency and the results will be in the same currency.
What is the benefit of extra payments?
Extra payments reduce the principal faster, which lowers total interest paid and shortens the loan term. Even adding a small amount each month can save thousands over the life of the loan.
