The Percentage Increase Formula
Common Mistakes

A Fórmula

Aumento % = ((Novo - Antigo) ÷ Antigo) × 100. De R$3.500 para R$4.000: +14,3%. Para calcular valor após aumento: Antigo × (1 + %/100). R$3.500 × 1,10 = R$3.850 (+10%). A média de aumento salarial no Brasil: 3-6%/ano.

Contexto

Se seu aumento é menor que o IPCA, seu poder de compra caiu. +4% de aumento com IPCA de 5%: você perdeu 1% de poder real.
