EOQ Calculator for Manufacturing
Calculate your Economic Order Quantity to minimize inventory costs, determine optimal reorder points, and maximize working capital efficiency.
The Wilson Formula
EOQ = √(2 × D × S / H)
Where D = Annual Demand, S = Ordering Cost, H = Holding Cost
What Does EOQ Solve?
Find the sweet spot where your total inventory costs are minimized
Ordering Too Often?
High ordering costs eat into profits. Each PO costs time, shipping, and processing.
Holding Too Much?
Excess inventory ties up working capital, increases storage costs, and risks obsolescence.
EOQ = Balance
EOQ finds the optimal quantity where ordering costs equal holding costs - minimizing total costs.
