The Percentage Increase Formula
Common Mistakes

La Fórmula

Aumento % = ((Nuevo - Original) ÷ Original) × 100. De $45,000 a $52,000: ((52000-45000)÷45000)×100 = 15.6% de aumento. Para calcular el valor después del aumento: Original × (1 + porcentaje/100). $45,000 con 15% de aumento: $45,000 × 1.15 = $51,750.

Contextos Comunes

Aumento salarial: el promedio anual es 3-5%. Inflación 2026: ~3%. Rendimiento de inversiones: S&P 500 promedio histórico ~10%/año. Si tu aumento salarial es menor que la inflación, tu poder adquisitivo está bajando aunque ganes "más". Un aumento del 3% con inflación del 3.5% = disminución real del 0.5%.
