Calculate percent yield from actual yield and theoretical yield. This tool helps students, teachers, and lab users measure reaction efficiency quickly.
Enter the actual yield and theoretical yield below. Use the same unit for both values to get an accurate percentage.
A percent yield calculator is a chemistry tool used to compare the actual amount of product collected from a reaction with the theoretical amount expected from calculations.
It is commonly used in labs, chemistry homework, experiments, and reaction analysis to understand how efficient a chemical reaction was.
Check how much product was collected compared with the expected reaction result.
Solve percent yield problems quickly using actual and theoretical yield values.
Understand whether a reaction produced a high, low, or unusual yield percentage.
Percent yield is calculated by dividing actual yield by theoretical yield and multiplying the result by 100.
Actual yield is the amount of product you really get from the experiment. Theoretical yield is the maximum amount of product expected from the balanced chemical reaction.
Enter the actual yield and theoretical yield in the calculator. Both values must use the same unit, such as grams, kilograms, moles, pounds, or ounces.
The calculator applies the percent yield formula and shows the result as a percentage. You can also choose how many decimal places you want in the answer.
Actual yield is the real amount of product obtained from a chemical reaction or lab experiment.
Theoretical yield is the maximum amount of product that should be produced based on stoichiometric calculations.
Yes, but a result above 100% usually means there may be impurities, extra moisture, measurement error, or incomplete drying of the product.
Yes. Both values must be in the same unit. If one is in grams and the other is in kilograms, convert them first before calculating.
