Reorder Point Calculator

When should you order more stock?

Order too late and you sell out. Order too early and your cash sits on a shelf. The reorder point is the stock level that tells you today is the day.

Order now. You are at or below your reorder point.

The Inventory tab in the kit watches every product and marks REORDER the moment one reaches its level, with the cash you need to restock.

How the sum works

  1. Units sold per day = monthly sales divided by 30.
  2. Reorder point = units sold per day times (lead time in days plus safety stock days), rounded up.
  3. Days of stock you have = units in stock divided by units sold per day.

Questions

How much safety stock should I keep?

Enough to cover the delays you have actually had. If your supplier has been a week late before, a week of safety stock is a sensible start.

What about seasonal products?

Use the sales you expect in the coming month, not the month just gone. Ahead of a busy season, raise the monthly sales figure and the reorder point rises with it.

How much should I order each time?

Enough to last until the next delivery could arrive, within what your cash allows. Check your supplier's minimum order and any price breaks.
