Example of a linear Risk vs Return function and corresponding risk premium. A risk premium is a measure of excess return that is required by an individual to compensate being subjected to an increased level of risk. [1]
For example, in group health insurance an insurer is interested in calculating the risk premium, , (i.e. the theoretical expected claims amount) for a particular employer in the coming year.

By deducting the projected expected return of risk-free bonds from the estimated expected return of stocks, the risk premium can be calculated. For example, if the return on a stock is 17% and the risk-free rate over the same period of time is 9%, then the equity-risk premium would be 8% for the stock over that period of time. [5]

[15] The discount rate is assumed to be constant over the life of an investment; however, discount rates can change over time. For example, discount rates can change as the cost of capital ...
R f is the expected risk-free return in that market (government bond yield); β s is the sensitivity to market risk for the security; R m is the historical return of the stock market; and (R m – R f) is the risk premium of market assets over risk free assets. The risk free rate is the yield on long term bonds in the particular market, such as ...

When used in portfolio management, the SML represents the investment's opportunity cost (investing in a combination of the market portfolio and the risk-free asset).
