Treynor Ratio Calculator
Our Treynor ratio calculator helps you to analyze your portfolio's returns against systematic risk.

What Treynor Ratio Calculator does
The Treynor Ratio Calculator helps users analyze a portfolio's investment performance by measuring returns per unit of systematic risk. It calculates the Treynor Ratio, a key metric that shows how much return an investment generates for each unit of systematic risk (beta) taken, using the formula: (Portfolio Return - Risk-Free Rate) / Portfolio Beta. The result provides a standardized measure of risk-adjusted efficiency, allowing users to compare different asset classes or portfolios on equal footing. The tool requires inputs for beginning and ending portfolio value, portfolio return, risk-free rate, and portfolio's beta to produce the final ratio.
How to use the Omni Calculator Treynor Ratio Calculator
- 1
Enter the beginning portfolio value and ending portfolio value to calculate the portfolio return
- 2
Input the risk-free rate, typically the yield on government bonds
- 3
Provide the portfolio's beta value, which measures its sensitivity to market movements
- 4
View the calculated Treynor ratio result, which shows return per unit of systematic risk
- 5
Use the 'Share result' or 'Clear all' functions to manage your calculations
Best for
Investment analysts, financial advisors, and quantitative researchers who need to compare the risk-adjusted performance of different portfolios or asset classes using systematic risk metrics.
Limitations
- Relies on historical beta values which may not predict future performance
- Uses systematic risk only, ignoring total portfolio volatility
- Assumes a linear relationship between risk and return that may not hold in all market conditions
Treynor Ratio Calculator FAQ
- What is a good Treynor ratio value?
- A higher Treynor ratio indicates better risk-adjusted performance, as it means more return per unit of systematic risk. However, the ideal value depends on the risk-free rate and market conditions, so comparing ratios across similar investments provides the most meaningful insight.
- How does the Treynor ratio differ from the Sharpe ratio?
- The Treynor ratio uses beta (systematic risk) as its denominator, while the Sharpe ratio uses total standard deviation (total risk). This makes the Treynor ratio more appropriate for well-diversified portfolios where unsystematic risk has been eliminated.
- Can the Treynor ratio be negative?
- Yes, a negative Treynor ratio occurs when the portfolio return is below the risk-free rate, indicating the investment underperformed a risk-free asset given its level of systematic risk.
- Is the Treynor ratio suitable for all types of investments?
- The Treynor ratio works best for diversified portfolios or assets where beta can be meaningfully calculated. For individual stocks or concentrated positions, the beta measurement may be less reliable, and other metrics might provide more relevant risk assessment.
