Investors and portfolio managers use risk-adjusted performance metrics to evaluate investment efficiency. The Modigliani Ratio Calculator is a powerful tool that helps determine the risk-adjusted return of a portfolio relative to a benchmark.

Whether you are analyzing mutual funds, stocks, or investment portfolios, this calculator provides precise results instantly, enabling informed investment decisions and performance comparisons.

What Is the Modigliani Ratio Calculator?

The Modigliani Ratio (M²) measures the risk-adjusted return of a portfolio. It adjusts the portfolio’s return to match the risk level of a benchmark, typically the market index. The formula is: Modigliani Ratio (M²)=Portfolio Return−Risk-Free Rate×Portfolio Standard DeviationBenchmark Standard Deviation\text{Modigliani Ratio (M²)} = \text{Portfolio Return} – \text{Risk-Free Rate} \times \frac{\text{Portfolio Standard Deviation}}{\text{Benchmark Standard Deviation}}Modigliani Ratio (M²)=Portfolio Return−Risk-Free Rate×Benchmark Standard DeviationPortfolio Standard Deviation

Where:

Portfolio Return = The total return of the portfolio
Risk-Free Rate = Return of a risk-free investment (e.g., government bonds)
Portfolio Standard Deviation = Measure of the portfolio’s risk
Benchmark Standard Deviation = Measure of the benchmark’s risk

A higher Modigliani Ratio indicates better risk-adjusted performance, while a lower ratio suggests suboptimal risk-return efficiency.

This ratio is widely used for:

Evaluating portfolio performance relative to a benchmark
Comparing mutual funds or investment strategies
Supporting investment and risk management decisions
Optimizing portfolio returns while controlling risk

By entering portfolio return, risk-free rate, and standard deviations, the calculator instantly provides the Modigliani Ratio.

How to Use the Modigliani Ratio Calculator

Follow these steps to use the tool effectively:

Step 1: Enter Portfolio Return

Input the total return of your investment portfolio.

Step 2: Enter Risk-Free Rate

Input the return of a risk-free asset (such as government bonds).

Step 3: Enter Portfolio Standard Deviation

Input the portfolio’s standard deviation to measure risk.

Step 4: Enter Benchmark Standard Deviation

Input the benchmark’s standard deviation to normalize the risk comparison.

Step 5: Click Calculate

Press the Calculate button. The calculator will display:

Portfolio Return
Risk-Free Rate
Modigliani Ratio (M²)

Practical Example

Suppose a portfolio has a return of 12%, a risk-free rate of 2%, a portfolio standard deviation of 15%, and a benchmark standard deviation of 10%.

The calculator performs the following calculation: M2=2%+(12%−2%)×1015=2%+10%×0.6667=8.667%M² = 2\% + (12\% – 2\%) \times \frac{10}{15} = 2\% + 10\% \times 0.6667 = 8.667\%M2=2%+(12%−2%)×1510=2%+10%×0.6667=8.667%

Result:

Portfolio Return: 12%
Risk-Free Rate: 2%
Modigliani Ratio: 8.67%

This indicates that the portfolio achieved an 8.67% risk-adjusted return relative to the benchmark.
