Sortino Ratio Calculator
Calculate portfolio Sortino Ratio, downside standard deviation, and excess return over minimum acceptable return (MAR).
What is the Sortino Ratio Calculator?
The Sortino ratio evaluates portfolio risk-adjusted returns by isolating downside price volatility from total standard deviation to penalize only harmful negative portfolio fluctuations. It divides portfolio returns in excess of a minimum acceptable return target by downside semi-deviation, ignoring positive upside volatility that benefits investors. This equips fund managers and sophisticated investors with a superior risk-efficiency metric for asymmetric investment strategies with non-normal return distributions.
The Sortino Ratio differentiates harmful downside volatility from beneficial upside volatility by dividing excess return over a Minimum Acceptable Return (MAR) strictly by downside deviation, providing a superior performance metric for asymmetric return strategies.

How to Use the Sortino Ratio Calculator
Follow these 3 simple steps for instant, accurate calculations.
1. Input Portfolio Return & Target Hurdle (MAR)
Enter your portfolio's annualized compound return and your Minimum Acceptable Return (MAR or risk-free rate, e.g. 4.0%).
2. Enter Downside Deviation (σd)
Input the standard deviation of negative returns (downside semi-variance) below your target hurdle rate.
3. Analyze Downside Risk-Adjusted Alpha
Evaluate your Sortino Ratio score, compare it against benchmark hedge funds, and contrast with the traditional Sharpe Ratio.

Sortino Ratio Formula
Divides portfolio excess return over the Minimum Acceptable Return (MAR) by downside deviation (semi-variance of negative returns).
Core Sortino Ratio Calculator Inputs & Terminology
A risk-adjusted performance metric that penalizes only those returns falling below a specified target or minimum acceptable return.
The investor's hurdle rate or minimum target return (often zero or the risk-free rate).
The standard deviation of negative returns falling below the MAR threshold (semi-deviation).
Positive return variance above the target, which benefits investors and is excluded from the Sortino denominator.
