What Is Reorder Level?
Every storeroom has a moment when someone should call the supplier, and most owners only notice it once it has passed.
Reorder level is the stock count at which you place the next purchase order, set so that what is left on the shelf covers sales until the new delivery arrives. Indian cost accountants write it as ROL, one of four stock levels the ICAI syllabus teaches together.
How to Calculate Reorder Level
Two formulas are common, and they match when your safety stock equals the ICAI minimum level.
Reorder level = (average daily usage x average lead time) + safety stock
Reorder level = maximum daily usage x maximum lead time
The first is common in inventory guides. The second, from ICAI’s material costing practice set, needs no separate buffer, since the busiest day and slowest delivery build in the cushion.
Lead time means the whole wait until stock is usable, usually longer than the supplier’s quote, as our lead time page shows.
The Four Stock Levels Around It
Indian textbooks rarely teach reorder level alone.
| Level | Formula | What you do |
|---|---|---|
| Maximum | ROL + order quantity minus (lowest usage x shortest lead time) | Stop adding stock |
| Reorder | Highest usage x longest lead time | Place the order |
| Minimum | ROL minus (average usage x average lead time) | Watch closely |
| Danger | Average usage x emergency lead time | Buy locally, today |
The minimum level is what most owners call safety stock. Danger level is the one small outlets skip, yet it earns its place on a busy Saturday night, when the regular supplier is a day away, the storeroom is nearly bare and someone must decide whether to wait or send a runner to the market.
Reorder Level vs Reorder Quantity
Reorder level answers when. Reorder quantity answers how much.
| Aspect | Reorder level | Reorder quantity |
|---|---|---|
| Question | When to order | How much to order |
| Measures | Stock on hand | Size of the order |
| Set by | Usage and lead time | Usage, space and ordering cost |
| Changes | With season or supplier | With prices and pack sizes |
Textbooks use the economic order quantity formula for this, though most small outlets go by bag size or the supplier’s minimum.
Reorder Level Example
An Andhra meals restaurant in Guntur’s Brodipet uses Sona Masuri rice: 42 kg on an average day, 55 kg on a busy Sunday, 30 kg on its quietest. Its Tenali wholesaler takes two days on average, four at worst and one at best. A local trader can supply within a day, and the regular order is twelve 25 kg bags at Rs.1,465 each.
| Step | Working | Result |
|---|---|---|
| Reorder | 55 x 4 | 220 kg |
| Minimum | 220 minus (42 x 2) | 136 kg |
| Maximum | 220 + 300 minus (30 x 1) | 490 kg |
| Danger | 42 x 1 | 42 kg |
| Cost | 12 bags x Rs.1,465 | Rs.17,580 |
Note: this is an invented example for illustration only. The restaurant, supplier and prices are not real.
So the order goes out when the storeroom count hits 220 kg. The everyday formula lands there too: two average days of rice (84 kg) plus the 136 kg minimum as safety stock is 220. And if a Sunday rush drags stock to 42 kg before the Tenali truck arrives, the manager buys locally.
When a Reorder Level Stops Working
A reorder level is only as current as its usage and lead time, and both move:
- The season turns. Wedding months, Ramzan or summer can lift usage for weeks.
- The supplier changes. A new wholesaler’s lead time is a guess until a few deliveries land.
- The menu changes. A new dish using the same ingredient raises usage quietly.
- The item is perishable. Paneer, milk and greens usually run on standing daily orders or a par level.
Not every item deserves one. An ABC analysis picks out the few worth watching daily, and setting the level wrong on one of those can mean an out-of-stock alert mid-service.
Across the multi-outlet chains we work with at Petpooja, a common slip is copying one outlet’s reorder levels to the next. A stock and inventory management template with a column per outlet keeps them apart.

The arithmetic is easy. But trusting the usage figure behind it is harder.
For restaurants, Petpooja POSS runs item-wise auto deduction, low-stock alerts and day-end inventory reports, so usage is deducted item by item as sales happen, not guessed. Features differ by POS version.
For retail businesses, Petpooja Invoice offers centralised inventory management, real-time stock tracking and built-in reports. Our guide to inventory system features covers what else to check.
Work out reorder levels for your three busiest items and compare them with your actual orders.
Frequently Asked Questions
In practice, yes. Global guides say reorder point and Indian cost accounting texts say reorder level, or ROL, but both mean the stock count that triggers an order.
Orders go out while plenty is still on the shelf. More cash sits in the storeroom, and perishable items risk passing their shelf life before they are used.
Yes, for anything bought in bulk with a delivery time of more than a day, such as rice, oil or coffee beans. Daily deliveries usually run on a standing order or par level instead.
It should, if usage swings. A level set in a quiet month runs short in a festival or wedding month, so keep a peak-season figure too.
Whoever places orders, with the owner reviewing them each quarter. The person counting stock should not be the only one who can change a level.
