The formula to calculate the default risk premium is:
\[ DRP = RRA - RRT \]
Where:
In short, the default risk premium is a representation of the risk associated with an investment when compared to something like a treasury bond that has, in theory, almost no risk. It is calculated by subtracting the rate of return of a risk-free asset from the rate of return on the asset being considered.
Example 1:
Using the formula:
\[ DRP = 8 - 3 = 5\% \]
Example 2:
Using the formula:
\[ DRP = 12 - 4 = 8\% \]
