To calculate the percentage yield, two essential parameters are needed and these parameters are actual yield and theoretical yield.
The formula for calculating percentage yield:
%Yield = (Actual Yield ⁄ Theoretical Yield) x 100
Let’s solve an example;
Find the percentage yield when the actual yield is 12 with a theoretical yield of 26.
This implies that;
Actual yield = 12
Theoretical yield = 26
%Yield = (Actual Yield ⁄ Theoretical Yield) x 100
So, %Yield = (12 ⁄ 26) x 100
%Yield = 0.46 x 100
%Yield = 46.15
Therefore, the percentage yield is 46.15.
Calculating the Actual Yield when the Percentage Yield and the Theoretical Yield are Given
Actual yield = %yield x theoretical yield / 100
Let’s solve an example;
Find the actual yield when the %yield is 52 with a theoretical yield of 10.
This implies that;
%yield = 52
Theoretical yield = 10
Actual yield = %yield x theoretical yield / 100
So, Actual yield = 52 x 10 / 100
Actual yield = 520 / 100
Actual yield = 5.2
Therefore, the actual yield is 5.2.
Calculating the Theoretical Yield when the Percentage Yield and the Actual Yield are Given
Theoretical yield = %yield x actual yield / 100
Let’s solve an example;
Find the theoretical yield when the %yield is 60 with a actual yield of 8.

This implies that;
%yield = 60
Actual yield = 8
Theoretical yield = %yield x actual yield / 100
So, Theoretical yield = 60 x 8 / 100
Theoretical yield = 480 / 100
Theoretical yield = 4.8
Therefore, the theoretical yield is 4.8.
