Definition
The risk-free rate of return is a theoretical measure of return on an investment that is considered free of risk, meaning there’s no chance of default. It’s typically associated with government bonds, like Treasury bills, which are backed by the government. In practice, the risk-free rate provides a benchmark for what investors might expect to earn from an absolutely risk-free investment—even if such an investment is nearly mythical, much like a unicorn!
Risk-Free Rate vs Expected Return
| Feature | Risk-Free Rate | Expected Return |
|---|---|---|
| Definition | Rate of return with zero risk | Anticipated return on a risky investment |
| Basis | Usually based on government bonds | Based on market conditions, risks, and investor expectations |
| Risk Level | Zero risk | Varies (high, low, moderate) |
| Real-World Existence | Theoretical (mythical unicorn) | Exists (but often elusive!) |
| Formula Example | Yield of Treasury bond - Inflation | Weighted average of potential returns |
Formula and Explanation
To calculate the real risk-free rate, the following formula is commonly used:
\[ \text{Real Risk-Free Rate} = \text{Yield of Treasury Bond} - \text{Inflation Rate} \]
This means if you want to know how much your money can reliably grow, just adjust for the pesky sneaky inflation—a bit like ensuring your ice cream cone isn’t just a mirage on a hot day!

Examples
-
Example 1: If the yield on a 10-year Treasury bond is 3% and inflation is currently at 2%, then: \[ \text{Real Risk-Free Rate} = 3% - 2% = 1% \] So when you’re pondering if you’ll ever reach that beach house, remember it’s more about the real rate if you keep your money safe!
-
Example 2: If the yield on a Treasury bond is 5% and inflation is 5%, then: \[ \text{Real Risk-Free Rate} = 5% - 5% = 0% \] You might as well be hiding your cash under the mattress — inflation’s throwing a party without the music!
