Enter the quantity variance (units) and the total quantity (units) into the Calculator. The calculator will evaluate the Quantity Variance Percentage. 

Quantity Variance Percentage Formula

QVP = QV / TQ * 100


  • QVP is the Quantity Variance Percentage (%)
  • QV is the quantity variance (units)
  • TQ is the total quantity (units)

To calculate the Quantity Variance Percentage, divide the quantity variance by the total quantity, then multiply by 100.

How to Calculate Quantity Variance Percentage?

The following steps outline how to calculate the Quantity Variance Percentage.

  1. First, determine the quantity variance (units). 
  2. Next, determine the total quantity (units). 
  3. Next, gather the formula from above = QVP = QV / TQ * 100.
  4. Finally, calculate the Quantity Variance 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.
