💡 Why Real Return Matters

Nominal returns can be deceiving — your account balance may grow, but if inflation is higher, your purchasing power could actually shrink. Real return tells you what truly happened to your money.

Fisher Equation: (1 + Nominal) = (1 + Real) × (1 + Inflation)
Approximation: Real ≈ Nominal − Inflation
