What does the Sortino Ratio Calculator do?
Sortino Ratio Calculator works out the sortino ratio from the Portfolio Return, Risk-Free Rate, and Downside Deviation, using Finance conventions. With the defaults, sortino ratio calculator gives a sortino ratio of 0.90.
- Inputs: Portfolio Return, Risk-Free Rate, and Downside Deviation.
- Output: the sortino ratio, and the operations that led to it.
- Method: the Finance formula, applied to Portfolio Return, Risk-Free Rate, and Downside Deviation inside the browser tab.
Quick answer
sortino ratio calculator returns a sortino ratio of 0.90 with the default inputs (portfolio return of 12, risk-free rate of 3, downside deviation of 10).
How does the Sortino Ratio Calculator work?
Sortino Ratio Calculator computes the sortino ratio directly from your inputs — the Portfolio Return, Risk-Free Rate, and Downside Deviation feed the formula. The sortino ratio is worked out on the device, so nothing about your inputs is transmitted.
How the Sortino Ratio Calculator works
Anyone who has to explain a figure rather than just quote it will find Sortino Ratio Calculator useful, because the page records how the figure was reached instead of only what it is.
How to use it
- Portfolio Return — a core sortino ratio input applied directly — keep its units consistent with the label.
- Risk-Free Rate — one of the values sortino ratio builds from; the sortino ratio reflects exactly what you type.
- Downside Deviation — used in the first sortino ratio stage, so entering it accurately beats any later refinement.
- Look for the step list under the result on Sortino Ratio Calculator: it names each operation, which is what turns a number into a checkable result.
- Use the share link from Sortino Ratio Calculator to reopen a case later, change one value, and compare the new sortino ratio with the old one directly.
The formula behind the result
The engine behind Sortino Ratio Calculator evaluates the inputs in a single pass — no hidden iterations or adjustments — so the sortino ratio you see is exactly what the formula produces for the values you entered.
Worked example: with portfolio return of 12, risk-free rate of 3, downside deviation of 10, this sortino ratio calculation returns Sortino Ratio: 0.90. The same run reports Like the Sharpe ratio but only penalises downside volatility — above 1 is generally good, above 2 is strong.
The steps it follows:
- Formula: Sortino = (Return − Risk-free rate) ÷ Downside deviation
- Excess return = 12% − 3% = 9%
- ÷ 10% = 0.90
- Only returns below the target (usually the risk-free rate) count toward the deviation, so upside volatility does not hurt the score
Understanding the result
Interpret the output from Sortino Ratio Calculator against the inputs that produced it — the same number from different inputs can mean different things, which is why the pairing is always shown.
Where it helps
Where Sortino Ratio Calculator earns its keep: planning a purchase, comparing this result with a rival quote, and checking the arithmetic without a spreadsheet, and the smaller questions that sit around them.
Common mistakes
Mixing up inputs with similar labels is the classic sortino ratio mistake; the steps panel is the quickest way to spot a value that landed in the wrong field.
Tip: Sortino Ratio Calculator returns Sortino Ratio: 0.90 at its defaults; double the Portfolio Return (%) and it returns Sortino Ratio: 2.10.
Assumptions and limitations
The sortino ratio from Sortino Ratio Calculator describes one point in time; if a rate, a price or a rule moves later, the figure no longer applies.
Why use this calculator
Because the working is visible: Sortino Ratio Calculator shows each operation behind the output in the steps panel, so you can verify the result instead of trusting a black box.
Frequently Asked Questions
Which figure does sortino ratio calculator produce?
What separates Sortino Ratio Calculator from a bare number is the trail behind it: Portfolio Return, Risk-Free Rate, and Downside Deviation go in, the result comes out, and the route between the two stays on screen. Because the Finance conventions are stated rather than assumed, Sortino Ratio Calculator removes the guesswork about which method produced the sortino ratio.
How is the result calculated?
The first steps are formula: sortino = (return − risk-free rate) ÷ downside deviation, then excess return = 12% − 3% = 9%. Where the Finance method allows more than one common convention, Sortino Ratio Calculator uses the one named on the label and computes the sortino ratio with it from the first term to the last.
What should I have ready for Sortino Ratio Calculator?
Sortino Ratio Calculator needs Portfolio Return, Risk-Free Rate, and Downside Deviation and nothing else.
What if the Portfolio Return (%) were twice as large?
At the defaults Sortino Ratio Calculator returns Sortino Ratio: 0.90; doubling Portfolio Return (%) to 24 moves it to Sortino Ratio: 2.10.
What does the result from this page’s calculator tell you?
The main number the sortino ratio calculator returns is the sortino ratio for your exact inputs. Sortino Ratio Calculator answers the arithmetic and stops there — it cannot tell whether the Portfolio Return, Risk-Free Rate, and Downside Deviation you supplied describe a realistic case.
When would someone reach for the page?
Reach for the sortino ratio calculator when you need planning a purchase, comparing this result with a rival quote, and checking the arithmetic without a spreadsheet without a spreadsheet open beside you. Enter a deliberately wrong value once on Sortino Ratio Calculator and watch the figure swing; the size of the swing is the cost of getting that field wrong.
