Real Rate of Return Results
Formula used: Real Rate = [(1 + Nominal Rate) ÷ (1 + Inflation Rate)] - 1
0Note: This accounts for the compounding effect of inflation on investment returns
Example Calculations
Bond Investment Example
Scenario: Bond with 6.5% annual interest
Nominal rate: 6.5%
Current inflation: 2.4%
Real return: [(1.065 ÷ 1.024) - 1] × 100 = 4.004%
Result: Your investment gains 4% in purchasing power
Savings Account with Deflation
Scenario: 2% savings rate during deflation
Nominal rate: 2.0%
Deflation rate: -1.0% (prices falling)
Real return: [(1.02 ÷ 0.99) - 1] × 100 = 3.030%
Result: You gain 3% purchasing power as prices fall
Quick Reference
Fisher Equation
(1 + real) = (1 + nominal) ÷ (1 + inflation)
Simple Approximation
real ≈ nominal - inflation
Accurate for low rates (< 10%)

Understanding Real Rate of Return
What is Real Rate of Return?
The real rate of return is the annual percentage return on an investment adjusted for inflation. It represents the actual growth in purchasing power, showing how much your investment value increases in terms of what you can buy with that money.
Why Use the Fisher Equation?
