Real Rate of Return Calculator
Calculate the real rate of return on your investments after adjusting for inflation. The real rate of return shows the true purchasing power growth of your money.

Current Market Rates
US Inflation (2024): 2.5-3.5%
Stock Returns: 7-10% nominal
Bond Returns: 4-6% nominal
Note: Real return = Nominal - Inflation
Understanding Real Rate of Return
The real rate of return measures the actual growth in purchasing power of an investment after accounting for inflation. While nominal returns show paper gains, real returns show what you can actually buy with your money.
Real Rate of Return Formula
Real return calculation:
Real Return = [(1 + Nominal Return) ÷ (1 + Inflation Rate)] - 1
Or: Real Return = Nominal Return - Inflation Rate (approximation)
Why Real Returns Matter
- Purchasing Power: Shows actual buying power growth
- Inflation Impact: Reveals how inflation erodes returns
- Investment Comparison: Allows fair comparison across time periods
- Goal Achievement: Determines if you're meeting real financial goals
- Risk Assessment: Shows true risk-adjusted performance
Nominal vs. Real Returns
| Aspect | Nominal Return | Real Return |
|---|---|---|
| Definition | Paper return before inflation | Return after inflation adjustment |
| Accuracy | Overstates true performance | Shows actual purchasing power |
| Use Case | Short-term performance | Long-term wealth building |
| Impact of Inflation | Ignored | Explicitly accounted for |
Historical Real Returns
Historical data shows that while nominal returns can be impressive, inflation significantly reduces real purchasing power.
| Asset Class | Nominal Return | Inflation | Real Return |
|---|---|---|---|
| S&P 500 (1928-2023) | 10.3% | 2.9% | 7.1% |
| Bonds (1928-2023) | 5.4% | 2.9% | 2.4% |
| Gold (1971-2023) | 8.1% | 4.0% | 3.9% |
| Savings Account | 1.5% | 3.0% | -1.5% |
Calculating Real Returns
- Exact Method: Use the Fisher equation for precise calculations
- Approximation: Subtract inflation rate from nominal return
- Multi-Period: Compound both returns over time
- After-Tax: Consider taxes on nominal returns
- Risk-Adjusted: Compare real returns with risk levels
Fisher Equation
The relationship between nominal, real, and inflation rates:
(1 + Nominal Rate) = (1 + Real Rate) × (1 + Inflation Rate)
Rearrange to solve for any component
Investment Implications
- Goal Setting: Set realistic return expectations
- Asset Allocation: Choose assets that beat inflation
- Risk Tolerance: Understand volatility in real terms
- Retirement Planning: Plan for purchasing power needs
- Performance Evaluation: Assess true investment success
Beating Inflation
To maintain purchasing power, investments need to generate positive real returns. Historical data shows that stocks have generally provided the best inflation protection.
- Stocks: Historically 4-7% real returns
- Bonds: 0-2% real returns (varies with rates)
- Real Estate: 2-4% real returns
- Cash: Often negative real returns
- TIPS: Designed to provide positive real returns
Tip: Always focus on real returns when evaluating investment performance. A 10% nominal return during 3% inflation is only a 6.8% real return. Consider inflation-protected investments like TIPS for guaranteed real returns.
