What is Risk Premium and Why Should You Care?
Risk premium is the extra return you earn on an investment compared to a risk-free asset like government bonds. This premium compensates you for taking on additional risk beyond a guaranteed return.
Understanding risk premium helps you evaluate whether the potential returns of an investment justify the risks you are shouldering. It acts as a financial compass for comparing investment opportunities and making informed decisions.
How to Calculate Risk Premium
Here is the formula:
[\text{Risk Premium} = R_{i} - R_{f}]
Where:
- Risk Premium is the extra return earned for taking on risk (expressed as a percentage).
- R_i is the return on the investment.
- R_f is the return on a risk-free asset.
Calculation Example
A stock returned 7% over the past year, while a government bond returned 2%.
[\text{Risk Premium} = 7 - 2 = 5]
The risk premium is 5%, meaning the investment earned 5 percentage points above the risk-free rate.
