Enter the total food wasted (lbs) and the total food produced (lbs) into the Food Waste Percentage Calculator. The calculator will evaluate the Food Waste Percentage. 

Food Waste Percentage Formula

The following two example problems outline the steps and information needed to calculate the Food Waste Percentage.

FWP = FW / FP * 100


  • FWP is the Food Waste Percentage (%)
  • FW is the total food wasted (lbs) 
  • FP is the total food produced (lbs) 

To calculate a food waste percentage, divide the total food wasted by the total food produced, then multiply by 100.

How to Calculate Food Waste Percentage?

The following steps outline how to calculate the Food Waste Percentage.

  1. First, determine the total food wasted (lbs). 
  2. Next, determine the total food produced (lbs). 
  3. Next, gather the formula from above = FWP = FW / FP * 100.
  4. Finally, calculate the Food Waste Percentage.
  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.

total food wasted (lbs) = 10

total food produced (lbs) = 20

FWP = FW / FP * 100 = ?
