EOQ Calculator — free online order quantity tool

If you keep stock, you have probably guessed at how much to order each time. Order too much and your money sits on a shelf. Order too little and you are placing tiny orders over and over. There is a sweet spot, and we added a free tool that finds it for you — EOQ Calculator — right in your browser.

What it does

It works out your Economic Order Quantity: the order size that keeps the total of your ordering costs and your holding costs as low as possible. You type in three numbers, and it gives you back the best quantity plus the full breakdown of the costs behind it, so you can see exactly where the number comes from.

Nothing leaves your device

The whole thing runs in your browser. Your numbers are never uploaded, never saved on a server, and nobody else sees them. When you close the page, they are gone.

How to use it

  1. Open EOQ Calculator.
  2. Enter your three numbers: yearly demand, the cost to place one order, and the cost to hold one unit for a year.
  3. Read your best order quantity and use the breakdown to plan your next order.

It's free with no limit. There are more small tools on the Apps page.
