Inventory Variance Formula

The following formula is used to calculate the inventory variance for a given actual and expected inventory.

V = A - E

Variables:

  • V is the inventory variance
  • A is the actual inventory
  • E is the expected inventory

To calculate the inventory variance, subtract the expected inventory from the actual inventory. This will give you the variance, which can be positive or negative depending on whether the actual inventory is higher or lower than the expected inventory.

What is Inventory Variance?

Inventory variance is the difference between the actual inventory and the expected inventory. It is a crucial metric in inventory management as it helps businesses identify discrepancies that may indicate issues such as theft, damage, or errors in inventory tracking. A positive variance indicates that there is more inventory than expected, while a negative variance indicates a shortage. Regularly calculating and analyzing inventory variance can help businesses maintain accurate inventory records and improve overall inventory management processes.

How to Calculate Inventory Variance?

The following steps outline how to calculate the Inventory Variance.


  1. First, determine the actual inventory (A).
  2. Next, determine the expected inventory (E).
  3. Finally, calculate the inventory variance using the formula V = A – E.
  4. After inserting the values and calculating the result, check your answer with the calculator above.
