Cómo usar
- Introduce el importe del préstamo, la tasa de interés anual y el plazo en años.
- Revisa la cuota mensual, los intereses totales y el pago total en las tarjetas resumen.
- Usa el gráfico y la tabla para ver cómo cambian capital e intereses cada año.
Preguntas frecuentes
¿Qué muestra esta calculadora de amortización?
Calcula una cuota mensual fija para un préstamo totalmente amortizable y genera un calendario año por año que divide cada pago en capital e intereses. También muestra el saldo pendiente y los intereses acumulados en un gráfico.
¿Qué significan las líneas del gráfico?
Saldo pendiente (azul, descendente) es lo que aún debes. Intereses acumulados (verde, ascendente) son los intereses pagados hasta el momento. En los primeros años se paga más interés; en los últimos, más capital.
¿Qué fórmula se utiliza?
La cuota mensual usa PMT = P × [r(1+r)^n] / [(1+r)^n − 1], donde P es el importe del préstamo, r es la tasa mensual y n son los meses. Cada mes, interés = saldo × r y capital = cuota − interés.

Introducción
Una calculadora de amortización te ayuda a entender cómo se devuelve un préstamo a tipo fijo a lo largo del tiempo: cuánto es cada cuota mensual, cuánto va a intereses frente a capital y cómo el saldo pendiente llega a cero.
Introduce el importe del préstamo, la tasa de interés mensual y el plazo. La herramienta calcula tu cuota y muestra un calendario año por año más un gráfico interactivo.
¿Qué es una calculadora de amortización?
La Calculadora de amortización utiliza tres entradas:
- Importe del préstamo — total prestado
- Tasa de interés mensual (%) — coste mensual del préstamo
- Plazo del préstamo (años) — duración del reembolso
Estima:
- Cuota mensual — pago fijo cada mes
- Intereses totales — todos los intereses pagados durante el plazo completo
- Pago total — capital más intereses totales
Un gráfico interactivo y una tabla año por año muestran cómo se reparte el reembolso entre intereses y capital a lo largo del tiempo.
Entender las líneas del gráfico
El gráfico muestra dos líneas que siguen el progreso del reembolso del préstamo.
1. Saldo pendiente (línea azul)
Qué muestra: Cuánto aún debes al final de cada año.
Por qué importa: Esta línea desciende hacia cero a medida que se paga el préstamo. La curva es más pronunciada en los últimos años, cuando más de cada cuota va a capital.
2. Intereses acumulados (línea verde)
Qué muestra: Total de intereses pagados desde el inicio hasta cada año.
Por qué importa: Esta línea sube a lo largo del préstamo. La mayor parte de los intereses se paga al principio, cuando el saldo es más alto — un dato clave para comparar costes de préstamo.
Cómo se calcula la cuota mensual
La herramienta asume una cuota mensual fija en un préstamo totalmente amortizable:
PMT = P × [r(1 + r)^n] / [(1 + r)^n − 1]
Donde:
P= importe del préstamor= tasa mensual ÷ 12 (tasa mensual en decimal)n= años × 12 (número de meses)PMT= cuota mensual
Cada mes:
- Interés = saldo pendiente ×
r - Capital = cuota − interés
- Nuevo saldo = saldo anterior − capital
Si la tasa es 0 %, la cuota se simplifica a P / n.
Casos de uso habituales
- Estimar cuotas mensuales para una hipoteca, préstamo de coche o préstamo personal.
- Ver el coste total de intereses antes de pedir un préstamo.
- Comparar cómo un plazo más corto o una tasa más baja reduce los intereses pagados.
- Enseñar cómo la amortización pasa de cuotas con mucho interés a cuotas con mucho capital.
Cuota fija vs capital fijo mensual
No todos los préstamos usan la misma estructura. Esta herramienta usa cuota mensual fija (amortización): el pago total se mantiene, mientras cambia la parte de interés y capital. Con capital fijo mensual (trả gốc đều), el capital mensual es fijo y el pago total baja.
| Cuota fija (esta herramienta) | Capital fijo mensual | |
|---|---|---|
| Qué se mantiene fijo | Pago total cada mes | Capital cada mes |
| Qué cambia | Sube el capital, baja el interés | Baja el pago total |
| Primeros meses | Pago total más bajo | Pago total más alto |
| Interés total (misma tasa y plazo) | Mayor | Menor — amortización más rápida |
| Común en | EE. UU., Europa, India, Japón, muchas hipotecas | China, Vietnam, algunos préstamos corporativos asiáticos |

Buenas prácticas
- Confirma si tu prestamista usa las mismas reglas de redondeo para la cuota final.
- Impuestos, seguros y comisiones no están incluidos salvo que ajustes las entradas mmensualmente.
- Los pagos extra de capital no están modelados — esta herramienta asume solo cuotas fijas programadas.
- Trata los resultados como estimaciones de planificación, no garantías ni asesoramiento financiero.
