### Examples of Market Risk Premium Formula (with Excel Template)

Let’s see some simple to advanced examples of Market Risk Premium Formula.

#### Example #1

Let us take an example of an investor who has invested in a portfolio and expects a rate of return of 12% from it. In the last year, government bonds have given a return of 4%. Based on the given information, determine the market risk premium for the investor.

Therefore, the calculation of market risk premium can be done as follows,

- Market risk premium = 12% – 4%

**Market risk premium will be-**

Based on the given information, the market risk premium for the investor is 8%.

#### Example #2

Let us take another example where an analyst wants to calculate the market risk premium offered by the benchmark index X&Y 200. The index grew from 780 points to 860 points during the last one year, during which the government bonds have given an average 5% return. Based on the given information, determine the market risk premium.

For the calculation of Market Risk Premium, we will first calculate the Market Rate of Return based on the above-given information.

- Market rate of return = (860/780 – 1) * 100%
- = 10.26%

Therefore, the calculation of market risk premium can be done as follows,

- Market risk premium = 10.26% – 5%

- Market risk premium = 5.26%
