Measure the risk-adjusted return of your investments with our Sharpe Ratio calculator. Understand how much excess return you're earning for each unit of risk you take, and make more informed portfolio decisions.
See how Sharpe Ratio analysis works in different investment scenarios.
Scenario: A balanced mutual fund with 8% portfolio return, 3.5% risk-free rate (10-year Treasury), and 10% standard deviation.
Scenario: An aggressive growth fund with 18% portfolio return, 3% risk-free rate, and 22% standard deviation.
Scenario: A well-managed hedge fund with 14% portfolio return, 2.5% risk-free rate, and 8% standard deviation (low volatility).
Scenario: A quantitative trading strategy with 25% portfolio return, 4% risk-free rate, and 7% standard deviation (very low volatility for the return).
Learn how the Sharpe Ratio is calculated and how to interpret the results for better investment decisions.
Rp = Portfolio return (expected or realized return of the investment)
Rf = Risk-free rate (typically the yield on 10-year U.S. Treasury bonds)
ฯp = Standard deviation of the portfolio's returns (measure of total risk)
Subtract the risk-free rate from the portfolio return: Excess Return = Portfolio Return - Risk-Free Rate. This represents the additional return you earn for taking on risk.
Standard deviation measures the volatility of the portfolio's returns. A higher standard deviation indicates greater risk and wider fluctuations in returns.
Sharpe Ratio = Excess Return รท Standard Deviation. This tells you how much excess return you're earning per unit of total risk.
Compare your Sharpe Ratio to the benchmarks: < 1.0 = Poor, 1.0-2.0 = Fair, 2.0-3.0 = Good, > 3.0 = Excellent. Higher ratios indicate better risk-adjusted performance.
| Sharpe Ratio Range | Interpretation | Description |
|---|---|---|
| < 1.0 | Poor | Returns are not sufficiently compensating for the risk taken. Consider reducing risk or seeking higher returns. |
| 1.0 โ 2.0 | Fair | Acceptable risk-adjusted returns. The investment is providing reasonable compensation for the level of risk taken. |
| 2.0 โ 3.0 | Good | The investment is delivering strong returns relative to the risk. Indicates effective risk management. |
| > 3.0 | Excellent | Exceptional risk-adjusted performance. Very difficult to achieve consistently. Often indicates a unique strategy or market opportunity. |
The Sharpe Ratio, developed by Nobel laureate William F. Sharpe, is one of the most widely used metrics for measuring risk-adjusted investment returns. It helps investors understand whether the returns of a portfolio are due to smart investment decisions or excessive risk-taking.
A high return alone doesn't tell you if an investment is good โ you need to know how much risk was taken to achieve that return. Two investments with the same 15% return can have vastly different risk profiles. The Sharpe Ratio quantifies this relationship, allowing you to compare investments on a level playing field.
The Sharpe Ratio is most valuable when used to compare similar types of investments or to track a single investment's performance over time. Here's how to apply it effectively in your investment analysis.
When choosing between two mutual funds, for example, look at both the absolute return and the Sharpe Ratio. Fund A might return 14% with a 1.2 Sharpe Ratio, while Fund B returns 16% but has a 0.8 Sharpe Ratio. Fund A may be the better choice because it delivers more return per unit of risk, even though its absolute return is lower.
