So, at some ideal level, the total costs will be at a minimum. This optimum level is stated as the economic order quantity or EOQ.

### Formula to calculate EOQ

This formula is also called Wilson’s formula, through this, we can calculate the value of EOQ. This formula is written as;

EOQ function

where

**Q** = Economical/Optimal order quantity

**P** = Ordering costs (setting costs)

**D** = Demand in year

**H** = Holding costs

Holding costs can be:

**CV (C = Interest, V = Products unit price)**

**CV + I (I = storage cost per unit)**

### What does the EOQ formula reveal?
