Enter the loan amount, the annual interest rate and the term in months, and the calculator returns the monthly installment, the total interest paid and the financial cost as a percentage of the principal.

Switch between the French method (a fixed installment for the whole term) and the German method (a fixed capital payment with a declining installment), and expand the full amortization table to see the capital, interest and remaining balance for every month.

The tool runs entirely in the browser, in Spanish, with figures formatted for Ecuador — currency in USD, decimal formatting in es-EC.
