What Is Reorder Level? Meaning, Formula and a Worked Example
For store keepers, purchase heads and owners of trading and manufacturing businesses: know exactly when to buy each item, so you stop both stockouts and overbuying.
What is reorder level? It is the stock figure that tells you it is time to buy again. Every item you keep has one, whether it is written down or held in a store keeper's head.
In many Indian SMEs the reorder decision is a feeling. The store keeper notices a thin rack, calls the owner, and the owner calls the supplier. By the time the goods arrive, a customer order has already been missed.
This page defines reorder level, shows the formula with a worked example, and explains how Apragya watches the figure for every item and godown.
Reorder level: the definition and the formula
Reorder level is the stock quantity at which you place the next purchase order for an item. When stock on hand falls to that figure, you buy, so that the new lot arrives before the shelf runs empty. It is also called the reorder point.
The common formula is: reorder level = average daily usage x lead time in days + safety stock. Lead time is the gap between raising the order and the goods being usable in your godown, including approval, transit and inspection.
Worked example: a fastener dealer sells 40 boxes of an M8 bolt a day on average. The supplier takes 8 days to deliver. Safety stock is 400 boxes. Reorder level = 40 x 8 + 400 = 720 boxes. When stock touches 720, the order goes out.
A simpler textbook version, used when usage swings a lot, is maximum daily usage x maximum lead time. With a worst case of 60 boxes a day and 12 days, that also gives 720. Either way, the figure is per item and per godown, and it needs review when demand or suppliers change.
- Find average daily usage over the last three to six months.
- Measure lead time from order to usable stock, not just transit.
- Decide safety stock for the risk you can accept.
- Multiply usage by lead time and add safety stock.
- Review the figure each quarter or when a supplier changes.
An example: a hardware distributor in Rajkot
Take an illustrative distributor stocking 1,800 items across two godowns. Reorder levels were set once, years ago, and fast movers kept running out while slow ones piled up.
From a falling stock figure to a draft order
Stock falls
M8 bolts drop to 700 boxes in the main godown.
Level crossed
The rule for that item and godown says 720.
Daily scan
The scan picks up every item below its level.
Draft order
One draft per preferred supplier and godown.
Buyer approves
Quantities checked, then sent to the supplier.
The distributor recalculated levels for its top 200 items from six months of sales. Within a month the buyer was approving draft orders each morning instead of phoning around, and the bolts that used to run out every fortnight stayed on the shelf.
How Apragya uses the reorder point in inventory
Step 1 of 5
Rules per item and godown
Each reorder rule holds the reorder level and the quantity to order.
- Rules per item and godown: Each reorder rule holds the reorder level and the quantity to order.
- Live stock figures: Receipts, sales and transfers update stock the moment they are posted.
- Scheduled scan: A daily scan finds every item at or below its level.
- Draft purchase orders: Drafts are grouped by preferred supplier and godown, without duplicates.
- AI suggestions: A stock optimiser agent can suggest reorder points and safety stock from history.
What a missing reorder level costs
Lost orders
Customers buy elsewhere when the item is out of stock for a week.
Rush freight
Emergency buying means premium rates and express transport.
Dead stock
Guesswork in the other direction ties cash up in slow items.
Daily firefighting
Someone has to walk the racks every morning to decide what to buy.
Reorder level formula in a sheet, against Apragya
A spreadsheet can hold the formula, but it cannot see stock move. Someone still has to paste the day's figures in and remember to look. The value of a reorder level is in being checked every day, for every item, without effort.
Reorder tracking, two ways
| Feature | Spreadsheet | Apragya inventory |
|---|---|---|
| Stock figure | Pasted in from the books | Updated on every posting |
| Per godown | Usually one figure per item | A rule per item and godown |
| Checking | When someone remembers | A daily scan |
| Next step | Phone call to the supplier | Draft order for approval |
| Review | Rarely | AI suggestions from history |
