Information Ratio: Meaning, Formula and Calculation Explained

Key Insights 

1. The Information Ratio shows how consistently a fund manager focuses on skill rather than just returns.

2. A score above 0.5 on the Information Ratio usually means the manager has real skill, not just average market results.

3. Investors get the best view of performance when they look at both the Information Ratio and the Sharpe Ratio together.

You will know that the information ratio is different from the Sharpe ratio, and learning how to information ratio calculation? 

The key difference between Sharpe ratio and the information ratio is that the latter focuses on performance compared to a benchmark. Some investors looking at mutual funds, the information ratio in mutual fund is a strong way to judge a manager’s skill.

What is Information Ratio?

Are you frustrated with metrics that don’t tell the whole story? 

The Information ratio portfolio performance measures how consistently a portfolio outperforms its benchmark. When you move beyond comparing sharpe vs information ratio, you start to see where real manager skill shows up.

You can think of a batting average for fund managers. Unlike the information ratio vs sharpe ratio, the information ratio focuses on active returns compared to tracking error. 

Information ratio is a portfolio performance measure that assesses skill. Do you know? What is a good information ratio starts at 0.5.

Example:

I compared two funds, and both performed well when looking at the sharpe vs information ratio. However, when I focused on the information ratio vs sharpe ratio evaluation, Fund A scored 0.85. This shows what a good information ratio looks like in practice.

Formula and Calculation of the Information Ratio (IR)

The information ratio portfolio performance measures via formula takes raw returns and turns them into a clear way to determine whether the investor's returns are due to skill or luck.

Here is the Information Ratio Formula:

IR = Portfolio Return − Benchmark Return / Tracking Error

Or simply:

IR = Active Return / Tracking Error

Let’s understand the Information Ratio formula with the real life example:

Take the Mirae Asset Large Cap Fund as an example. It is one of India's top-performing equity funds.

• Fund Return: 14.2%
• Benchmark (Nifty 100) Return: 11.5%
• Active Return: 2.7%
• Tracking Error: 3.4%

IR= 2.7%​ / 3.4%= 0.79

A score of 0.79 shows strong and regular performance. This is well above the 0.5 level that most analysts consider significant. 

Now, understand what this score means, or what is a good information ratio?
 

A high IR score helps show which fund managers have real skill, not just good luck.

Information Ratio in a Mutual Fund

The Information Ratio helps you see if your mutual fund manager consistently earns the fees you pay.

Why Does It Matters in Mutual Funds?

Many investors focus only on high returns, but experienced investors look for consistency return and risk management. The Information Ratio shows if a fund manager really outperforms their benchmark or just benefits from market trends.

If a mutual fund’s Information Ratio is above 0.5, it suggests the manager is skilled and can be trusted with your investment.

Difference between Sharpe Ratio and Information Ratio 

Both ratios measure your performance in the stock market, but each one answers a different question to help you invest.

The Core Difference

The Sharpe Ratio shows how much return you get for each unit of total risk. The Information Ratio shows how much extra return you earn for each unit. 

You can think of the Sharpe Ratio as efficiency. On the other hand, the Information Ratio measures a manager’s skill compared to a benchmark.

Here is the table, which shows you step by step comparison:
 

Which metric should you use?

Use the Sharpe ratio to compare funds from different categories. Use the Information Ratio to see if your active fund manager is truly outperforming their benchmark. If investors use both at the same time, it will give investors the clearest view of performance.

Use both ratios together. The Sharpe ratio measures efficiency, while the Information Ratio highlights the manager's skill.

Conclusion

The Information Ratio is a powerful way to measure a manager’s real skill, not just luck or market trends, and you can learn how the formula works, see how it compares to the Sharpe Ratio, and use it to choose the best mutual fund with clear data.

FAQs

1. What is the formula for the Information Ratio? 

The information ratio calculation is: Information Ratio = (Portfolio Return − Benchmark Return) / Tracking Error. It measures how consistently a portfolio generates excess returns compared to its benchmark relative to the level of active risk taken.

2. What is the difference between the Sharpe Ratio and the Information Ratio? 

The Sharpe Ratio measures return compared to the risk-free rate using total portfolio risk. The Information Ratio measures how consistently a portfolio outperforms its benchmark using tracking error. Sharpe vs information ratio compares overall efficiency versus manager skill.

3. Why can’t analysts use the Information Coefficient alone to judge a portfolio manager?  

The Information Coefficient (IC) measures prediction accuracy in stock selection. However, it does not show how those predictions affect portfolio returns. The Information Ratio considers both active returns and risk, which makes it a more practical measure of a manager’s real performance.

4. Why can a higher active risk lower the Information Ratio when constraints exist?  

Portfolio constraints limit investment choices. If active risk increases but returns do not increase proportionally, tracking error rises faster than excess returns. This reduces the Information Ratio, meaning the manager is taking more risk without generating enough additional return.

5. What is a good Information Ratio?

A good Information Ratio is generally above 0.5. This suggests the fund manager is consistently outperforming the benchmark. Scores above 0.75 indicate strong skill, while values above 1.0 are rare and exceptional in active portfolio management.
