The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking Step 7: Use the annualized return and annualized standard deviation data to calculate a Sharpe ratio.

It is defined as the difference between the returns of the investment and the risk-free return, divided by the standard deviation of the investment. It represents the additional amount of return that an investor receives per unit of increase in risk. It was named after William F. Sharpe, who developed it in 1966.

To calculate the Sharpe Ratio, find the average of the “Portfolio Returns (%)” column using the “=AVERAGE” formula and subtract the risk-free rate out of it.
