💵

Calculation Parameters

Specify your inputs below.

Calculated Result

Portfolio Excess Return 8.50%
Sortino Ratio 1.42
💡

Expert Tip

The Sortino ratio is often preferred over the Sharpe ratio because it only penalizes harmful downside volatility.

How this Calculator Works

This calculator computes the Sortino Ratio, a variation of the Sharpe Ratio that only penalizes negative return volatility. Since positive spikes are beneficial to investors, the Sortino Ratio offers a more accurate assessment of downside risk exposure. Active traders use it to evaluate risk management.

Formula & Methodology

Sortino Ratio = (Portfolio Return - Risk-Free Rate) / Downside Deviation - Portfolio Return is the average annual return rate of the assets. - Risk-Free Rate is the return on riskless deposits. - Downside Deviation is the standard deviation of negative portfolio returns.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

A hedge fund returns 12% with a downside deviation of 8%. The risk-free interest rate is 2%. 1. Calculate excess return: 12% - 2% = 10%. 2. Divide by downside deviation: 10% / 8% = 1.25. Result: The Sortino Ratio is 1.25.

FAQ

How does compounding frequency impact investment returns?
More frequent compounding (e.g. monthly or daily vs. annually) generates higher effective annual yields (APY) because interest is calculated on accumulated interest earlier in the period.
What is the difference between Sharpe Ratio and Sortino Ratio?
The Sharpe ratio divides excess return by total standard deviation (both upside and downside volatility), whereas the Sortino ratio divides excess return by downside deviation only.
Should investment calculators replace professional wealth management?
No. Investment calculators model financial mathematics under assumed growth rates. Actual market performance fluctuates, so consult a licensed financial planner (CFP) or RIA for personalized advice.
