Como funciona o cálculo de juros compostos

Nos juros compostos, a cada período os juros são incorporados ao saldo, e o período seguinte rende sobre esse novo valor. Com aportes mensais, cada depósito também passa a render a partir do mês seguinte.

Fórmula do montante

M = C·(1 + i)ⁿ + A·[(1 + i)ⁿ − 1] / i
  • M: montante final
  • C: capital inicial
  • A: aporte mensal
  • i: taxa mensal (decimal)
  • n: número de meses

Exemplo prático

Investindo R$ 10.000 iniciais e R$ 500 por mês a 10% ao ano durante 10 anos, você acumula cerca de R$ 126 mil — dos quais mais de R$ 56 mil são apenas juros.
