Enter the extracted weight (g) and the original weight (g) into the Calculator. The calculator will evaluate the Extraction Yield. 

Extraction Yield Formula

EY = EW / OW * 100


  • EY is the Extraction Yield (%)
  • EW is the extracted weight (g)
  • OW is the original weight (g)

To calculate Extraction Yield, divide the total extracted weight by the original material weight, then multiply by 100.

How to Calculate Extraction Yield?

The following steps outline how to calculate the Extraction Yield.

  1. First, determine the extracted weight (g). 
  2. Next, determine the original weight (g). 
  3. Next, gather the formula from above = EY = EW / OW * 100.
  4. Finally, calculate the Extraction Yield.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

extracted weight (g) = 90

original weight (g) = 100
