How it works

## How it works

**EOQ = square root of (2 x annual demand x cost per order / holding cost per unit per year).** The reorder point is daily demand times lead time, plus safety stock.

FAQ

## About this calculator

**What does EOQ assume?**

Steady demand, a fixed cost per order and a fixed holding cost per unit. Real demand varies, so treat the result as a starting point.

**What counts as holding cost?**

Storage, insurance, spoilage and the cost of cash tied up in stock, per unit per year.

**How is safety stock set?**

It is a cushion for demand or delivery surprises. The right level depends on how variable your demand and lead times are.

**Is anything saved?**

No. The math runs in your browser and nothing you enter is sent to us.

**Is this tax or financial advice?**

No. It is a calculator for general information. Check the numbers against your own records, and ask an accountant before you act on them.
