Percent Yield

Output: Press calculate

Formula:Percent Yield = (Actual Yield / Theoretical Yield) * 100

Introduction to Percent Yield

Percent yield is a measure of the efficiency of a chemical reaction. It represents the percentage of the theoretical yield that was actually obtained from a chemical reaction. In this formula, Percent Yield is calculated by dividing the actual yield by the theoretical yield, then multiplying by 100 to express the result as a percentage.

Parameter usage:


Data validation

Both actual yield and theoretical yield should be positive numbers.


This calculator evaluates the efficiency of a chemical reaction by computing the percent yield based on the actual and theoretical yields.
