Real vs Nominal Returns

The Fisher Equation

Real Return = [(1 + Nominal) / (1 + Inflation)] - 1

This is more accurate than simply subtracting inflation from the nominal return.

Why Real Returns Matter

Nominal returns tell you how much your money grows. Real returns tell you how much your purchasing power grows. If investments grow 10% but prices rise 3%, your actual wealth gain is about 6.8%.

Lösungsbeispiel

10% nominal return, 3% inflation, $10,000 over 10 years.

  1. Real return = (1.10 / 1.03) - 1 = 6.80%
  2. Nominal value = $10,000 x (1.10)^10 = $25,937
  3. Real value = $10,000 x (1.068)^10 = $19,307
  4. Purchasing power loss = $25,937 - $19,307 = $6,630
