Introduction
Welcome to the exciting world of Risk Premium calculation! This is where we take the boring task of assessing risk and add some pizzazz to it. So, what exactly is a Risk Premium? It’s the extra return that an investor requires to take on additional risk. And if you’re wondering how to calculate it, don’t worry, we’ve got you covered. Here’s the formula:
Risk Premium = Expected Return - Risk-Free Rate
Categories of Risk Premium Calculation
Let’s break down the different categories of Risk Premium calculations and what they mean:
| Category | Range | Interpretation |
|---|---|---|
| Low | 0-2% | Low risk, low reward |
| Medium | 2-5% | Moderate risk, moderate reward |
| High | 5-10% | High risk, high reward |
| Extreme | >10% | Very high risk, very high reward |
Examples of Risk Premium Calculation
Let’s see how the Risk Premium is calculated for different individuals:
| Name | Expected Return | Risk-Free Rate | Risk Premium |
|---|---|---|---|
| Bob | 8% | 3% | 5% |
| Jane | 12% | 4% | 8% |
| Tom | 6% | 2% | 4% |
Bob’s Risk Premium is calculated as 8% – 3% = 5%. He falls under the Medium category. Jane’s Risk Premium is 12% – 4% = 8%, which puts her in the High category. Tom’s Risk Premium is 6% – 2% = 4%, which is also in the Medium category.
