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%
