]]>Sharpe Ratio Formula = (Mean of Fund Returns – Risk Free Return) / Standard Deviation

For calculating Sharpe Ratio follow these steps:

- Decide Fund whose Sharpe Ratio you want to calculate
- Find the NAV on First Day of the Month
- Find the NAV on Last Day of the Month
- Calculate Return by Formula i.e. (Return = (NAV on Last Day – NAV on First Day) / NAV on First Day)
- Calculate Mean of the returns this will give us monthly return
- To calculate annualized return multiple monthly return calculated in step 5 with 12.
- Calculate Standard Deviation of the return
- To calculate annualized Standard Deviation multiple it with 12.
- Risk Free Return is assumed to be 8% (As bank is giving minimum 8% interest on Fixed Deposits this may change from time to time).
- Put all the values calculated in the formula to get value of Sharpe Ratio

**Example for calculating Sharpe Ratio:**

**SBI Magnum MidCap Fund.**

Month | NAV on First Day of the Month | NAV on Last Day of the Month | Return |

A | B | = (B-A)/A | |
