Cómo se calcula
Sistema francés (cuota fija): C = P × r × (1+r)^n / ((1+r)^n - 1).
La cuota se mantiene constante; el interés decrece y el capital crece mes a mes.
Sistema alemán (capital fijo): capital = P/n cada mes. Interés sobre saldo, cuota total decrece. Paga menos intereses totales pero las primeras cuotas son más altas.
Pagos extra al capital: reducen el saldo en una fecha específica. En francesa, la cuota mensual no cambia pero el préstamo termina antes; en alemana, el capital base por mes no cambia pero también termina antes y los intereses futuros bajan.
Cómo usarla

- Enter the annual rate. For example, 12% annual.

Preguntas frecuentes
What is French amortization?
The most common system used by banks: a fixed monthly payment where you pay more interest at the beginning and more principal at the end. Formula: C = P × r × (1+r)^n / ((1+r)^n - 1).
Does it include insurance and fees?
No. The calculator shows principal + interest only. Credit-life insurance, fees and other charges are added separately by your bank.
Does it work for mortgages?
Yes. The formula is the same. Only the term is longer (typically 120-360 months).
