Economic Order Quantity (EOQ) Calculator

The Economic Order Quantity (EOQ) Calculator substitutes your inputs (Annual demand, Order cost, Holding cost/unit) into the standard expression: EOQ = √(2 × Annual demand × Order cost ÷ Holding cost/unit). Every variable is read straight from the fields on this page, and the result is computed the moment you enter the values.

1. 1

   Step 1

   Enter the business metrics you want to analyze.

2. 2

   Step 2

   Hit "Calculate" and the result is computed automatically.

3. 3

   Step 3

   Review the result and details below before relying on it.

4. 4

   Step 4

   The breakdown lists your inputs — Annual demand, Order cost, Holding cost/unit next to the value computed by EOQ = √(2 × Annual demand × Order cost ÷ Holding cost/unit); read it before relying on the number.

5. 5

   Step 5

   Adjust one input at a time and compare scenarios: change Annual demand and re-run to see which variable moves the economic order quantity (eoq) result most.

• 1

  The Economic Order Quantity (EOQ) Calculator needs every variable in consistent units — Annual demand, Order cost, Holding cost/unit — before the standard formula returns a valid result, so check each field's unit before entering values copied from elsewhere.

• 2

  Treat the Economic Order Quantity (EOQ) output as a computed reference, not a guarantee: where money, health, or compliance is involved, have a professional confirm the inputs and the interpretation before you act on the number.

• 3

  Copy the Economic Order Quantity (EOQ) result together with the input values that produced it; a number without its documented inputs cannot be re-verified later, and assumptions are easy to forget once the session is closed.

• Annual demand and Order cost must be entered in one consistent unit system: months against years skews the Economic Order Quantity (EOQ) result silently. Convert every input to the unit named on its field first.

• Swapping Annual demand with Order cost computes a different quantity. If the Economic Order Quantity (EOQ) result looks implausible, check the labels first: each value must sit in the field its label names.
