Introduction to Risk-Adjusted Return Calculation Formula
The Risk-Adjusted Return (RAR) formula is a way to measure the amount of risk an investment takes on in relation to the return it generates. In other words, it’s a way to measure how much risk you’re taking on to get a certain amount of return. The formula is simple. Just divide the excess return (the return of the investment – the return of the risk-free investment) by the investment’s standard deviation.
RAR = (Return of the investment - Return of the risk-free investment) / Standard deviation of the investment
Types of Risk-Adjusted Return Calculations and Results Interpretations
There are different types of Risk-Adjusted Return calculations, and each has its own interpretation of the results. Here’s a table outlining the different categories/types/range/levels of Risk-Adjusted Return calculations and their results interpretation:
| Type | Range | Interpretation |
