Ejection Fraction Calculator
❤️ The human body. Use the Ejection fraction formula to find ejection fraction, stroke volume, end-diastolic volume: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Ejection fraction | % |
| Stroke volume | ml |
| End-diastolic volume | ml |
Worked example
Find the ejection fraction when Stroke volume = 70 ml, End-diastolic volume = 120 ml.
Using EF = SV/EDV × 100: Ejection fraction = 58.333 %.
Frequently asked questions
What is the formula for Ejection fraction?
EF = SV/EDV × 100.
What do the letters stand for, and what units are used?
Ejection fraction in %, Stroke volume in ml, End-diastolic volume in ml.
How do you calculate ejection fraction?
Put the values into EF = SV/EDV × 100. For example, with Stroke volume = 70 ml, End-diastolic volume = 120 ml, ejection fraction = 58.333 %.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (ejection fraction, stroke volume, end-diastolic volume) and fill in the others: it rearranges the formula for you.
