Enter the theoretical yield and the actual yield of your chemical reaction to calculate the percentage yield of said reaction.

Percent Yield Formula

The following formula is used to calculate a percentage yield.

Y = AY / TY *100
  • Where Y is the percent yield (%)
  • AY is the actual yield (g)
  • TY is the theoretical yield (g)

To calculate the percentage yield, divide the actual yield by the theoretical yield, then multiply by 100.

Percent Yield Definition

A percent yield, also referred to as a percentage yield, is the ratio of the actual yield of mass of a chemical reaction to the theoretical yield that the reaction should produce.

How to calculate percent yield?

When it comes to chemistry, calculating the percent yield of a reaction is pretty straightforward. It’s a simple percentage calculation based on the theoretical yield and observed result. You may have stumbled on the page looking for the percent yield of something other than a chemical reaction; you can still use this calculator! Simply enter the max yield in the theoretical section, and the actual yield, and it will create the percentage yield. This could be the square footage yield or yield of a sheet.

In chemistry, the units are often recorded in grams when it comes to chemical reactions. Still, this calculator can be considered unitless since the result is a percentage. Therefore, if the units match, you will yield something relevant.
