Investment Inflation Calculator

Calculate the 'Real' rate of return after adjusting for inflation.

Your Real Rate of Return
6.80%

Σ The Formula

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

Real World Examples

Standard Year
A 10% market return with 3% inflation results in a 6.8% real increase in wealth.
High Inflation
If you earn 5% interest but inflation is 6%, your purchasing power is actually shrinking by 0.94%.

# About This Calculator

The Investment Inflation Calculator uses the Fisher Equation to determine your actual gain in purchasing power.

It's a common mistake to simply subtract inflation from your return (e.g., 10% - 3% = 7%). While close, the true geometric relationship is slightly different because you're calculating the ratio of your new wealth to the new cost of goods.

How To Use

  1. Enter the **Nominal Interest Rate** (what the bank or ticker says).
  2. Enter the **Inflation Rate** (CPI or your personal cost increase).
  3. The **Real Rate** shows how much your actual wealth 'grew' in terms of what it can buy.
