How to Calculate using Calculator?

For calculating Sharpe’s Ratio, simply provide the following data to the calculator:

Mean Portfolio Return – It is the average of return on a portfolio. It can be based on past as well as future data. The formula for calculating the mean portfolio return from past data is as follows:

= ∑x / n

And for calculating mean portfolio return from future data, the formula is as follows:

= ∑P(x)

Where, x = Return on Portfolio (%)

n = Number of Years

P = Probability

Risk-Free Rate of Return – The risk-free rate of return is a rate on investment having no risk. It works as a benchmark for various other interest rates. Investment in treasury bills and government bonds is considered as a risk-free investment.

Therefore, (Rf) gives a result of returns generated by taking risks.

Standard Deviation – Standard deviation is the amount by which returns may fluctuate in correlation with its average return or mean. It is the expected risk of a portfolio. It represents volatility around the mean.

The formula for calculating standard deviation is:

  • From past data,

σ = √[∑(x – )2/n]

  • From future data,

σ = √[∑P(x – )2]
