How Much Candle Jar Inventory Should I Keep If My Supplier Takes Two to Four Weeks to Restock?
Aktie
What is the worked example? 40 jars a week on average, 55 in a busy week, restock in 2 to 4 weeks. Lead-time use is 40 × 3 = 120 jars; safety stock is 55 × 4 − 120 = 100 jars; reorder point 220 jars. Order 160 each time and you hold about 180 jars on average, ₹12,744.00 at ₹70.80 a jar.
Is "order when I run low" good enough? Not with a 4-week worst case. At 40 a week you use 160 jars while you wait; in a busy spell, 220. If "low" means fewer than that, you run out before the jars arrive.
What about Diwali? Use festive usage, not your yearly average. At 90 a week (110 at peak) the reorder point rises to 440 jars. Jars ordered on 26 September 2026 with a 2 to 4 week lead land between 10 and 24 October 2026, before Diwali on 8 November.

The reorder-point formula in plain numbers
Inventory with a restock delay has one job: to carry you from the moment you order until the jars arrive. Everything else follows from that. You need three numbers, all from your own records.
| Input | What it is | Where to get it | Example |
|---|---|---|---|
| Average weekly use | Jars poured per week over recent months | Production log or jars bought ÷ weeks | 40 |
| Peak weekly use | A busy but normal week (not a festival) | Your highest normal week in the log | 55 |
| Lead time (average and longest) | Order day to jars ready to pour | Your order history; ask the supplier for current dispatch times | 3 weeks average, 4 longest (2 shortest) |
Step 1: lead-time use
How many jars you normally use while you wait: average weekly use × average lead time. 40 × 3 = 120 jars.
Step 2: safety stock
The extra that covers a busy spell and a slow restock at the same time: (peak weekly use × longest lead time) − lead-time use. 55 × 4 − 120 = 100 jars. This is one common, simple rule. Larger operations often use a statistical version based on how much weekly use and lead time vary, but with a few months of records the simple rule is easier to trust and check.
Step 3: reorder point
Lead-time use + safety stock: 120 + 100 = 220 jars. Notice that with this safety-stock rule the reorder point always equals peak use × longest lead (55 × 4 = 220). That is a useful check: if your reorder point is below peak use × longest lead, a busy month with a slow restock will empty your shelf.
What counts as lead time
"Two to four weeks to restock" is the supplier's number. Your lead time is longer, because a jar is not usable the moment the supplier has it.
| Part | What happens | How to find it |
|---|---|---|
| Your ordering delay | Days between stock hitting the reorder point and you placing the order | Only zero if you check stock often; see the weekly routine below |
| Supplier restock (if out) | The 2 to 4 weeks in the question | Ask whether a restock is on order and when |
| Dispatch and transit | From the supplier's door to yours | Your delivery history; ask for a dispatch date with each order |
| Receiving and inspection | Unboxing, counting, checking for chips and cracks, washing | Usually a day or two; longer for large deliveries |
If the 2 to 4 weeks is the supplier's restock time and the jar is currently out, your lead time is the restock plus transit plus inspection. If the jar is in stock and the 2 to 4 weeks is really dispatch and transit, add inspection only. Get the definition straight with your supplier, then log your real order-to-ready times; after a few orders you will have an honest average and longest. CSI dispatches from Pune and does not publish delivery times on its listings; ask us for current stock and a dispatch time to your pin code.
Where the simple rule over- or under-protects
Too cautious when busy weeks and slow restocks rarely coincide. The rule assumes your peak week and your longest lead happen together. If both are rare, that is generous cover. A lighter version uses peak use × average lead (55 × 3 = 165) as the reorder point: it holds 55 fewer jars (₹3,894.00 less cash) and accepts a shortfall in the month a busy spell meets a four-week restock. That is a business choice, not a maths error; make it knowingly.
Not cautious enough when use is growing. A reorder point built on last quarter's average lags a business that is growing every month. Recompute monthly, and use the most recent four weeks rather than a long average when the trend is clearly up.
Not cautious enough with a thin record. If you have logged only two or three orders, your "longest" lead time is probably not the longest you will see. Until you have more history, add a week to it, and ask the supplier what their slowest recent dispatch was.
When the supplier's stockouts, rather than routine restocks, are the real problem, long and unpredictable, a reorder point is not enough on its own: the stockouts guide sizes a buffer to the longest stockout and shows how a qualified second jar shrinks it.
Worked example: 40 jars a week, 2 to 4 weeks to restock
A maker pours about 40 jar candles a week in White Matte 200 ml jars (₹70.80 each), 55 in a busy week. Restock takes 2 to 4 weeks, 3 on average. Here are four ways to decide when to reorder, and what each does. All inputs are illustrative.
| Policy | Reorder when stock (incl. on order) reaches | Worst case: peak use, 4-week lead | Average jars on hand | Average cash in jars |
|---|---|---|---|---|
| "When I run low" (about two weeks' use) | 80 | Runs short even in an average cycle; at peak, empty after about 1.5 weeks and about 2.5 weeks without jars | About 80 | ₹5,664.00 |
| Average use × longest lead | 160 | 60 jars short, roughly the last week | About 120 | ₹8,496.00 |
| The formula (peak × longest lead) | 220 | Reaches zero on delivery day; no shortfall | About 180 | ₹12,744.00 |
| "Several months" (order 480 at 220) | 220 | No shortfall | About 340 | ₹24,072.00 |
Average jars on hand is roughly the safety stock plus half an order (the stock rises by a full order on delivery and falls to about the safety stock before the next one). For the formula row that is 100 + 80 = 180 jars. Right after an average delivery you hold about 260 jars (₹18,408.00). The last row shows what "keep several months" buys you with a 2 to 4 week restock: no extra protection against running out, because the reorder point already covers the worst case, and ₹11,328.00 more cash on the shelf on average.
How much to order each time
The reorder point tells you when; the order quantity tells you how many. Larger orders mean fewer orders (less ordering time, fewer freight charges, fewer deliveries to inspect) but more cash and space tied up. A practical starting point is two to six weeks of average use per order (our judgement), adjusted for three things:
| Factor | Pushes the order | Example |
|---|---|---|
| Freight or fixed charges per order | Up: fewer, larger orders spread the fixed part | See the landed-cost guide for freight per usable jar |
| Pack sizes and price steps | To the nearest pack; up to a step if the step pays | Salsa clear: ₹40.12 at 5 Pcs, ₹29.50 from 50 |
| Cash and space | Down: every extra jar on the shelf is cash not spent elsewhere | 480 jars at a time holds ₹11,328.00 more on average than 160 |
| Risk of change | Down: a new label, colour or jar makes old stock awkward | Keep orders small while a design is new |
Rounding to packs
Round the order to the supplier's pack sizes, and check whether rounding up earns a better price. With CSI jars: the White Matte and Clear Golden Lid 150 g listings are flat per jar across their packs, so round to the most convenient pack (sixteen packs of 10, or eight packs of 20). The 200ml Salsa clear listing steps from ₹40.12 to ₹29.50 at 50, so a 160-jar order bought as three 50s and two 5s is ₹4,826.20, and four 50s (200 jars) is ₹5,900.00: ₹1,073.80 more for 40 extra jars at the lower price, which you use in the next cycle. Either choice is reasonable; just count the extra 40 in "on order" so you don't double-order.
When usage jumps: Diwali, 8 November 2026
The formula uses weekly use during the lead time, so when use is about to rise, the reorder point must rise first. Suppose festive orders take you to 90 jars a week, 110 in the busiest week. With the same 2 to 4 week lead:
| Season | Average / peak per week | Lead-time use (× 3) | Safety stock | Reorder point | Safety stock in cash |
|---|---|---|---|---|---|
| Normal | 40 / 55 | 120 | 100 | 220 | ₹7,080.00 |
| Festive build-up | 90 / 110 | 270 | 170 | 440 | ₹12,036.00 |
Now the calendar. Diwali falls on 8 November 2026, 43 days after these prices were checked on 26 September 2026. Jars ordered today with a 2 to 4 week lead arrive between 10 October and 24 October 2026. Allow a day or two to inspect, then pouring and a cure before sale (many soy makers allow about two weeks as common practice): jars that arrive on 24 October leave very little margin before 8 November. The honest conclusion for anyone with a 4-week worst case is that the festive reorder is due now, not when the shelf looks low. Christmas (25 December 2026) and Valentine's Day (14 February 2027) follow the same arithmetic: raise the reorder point about one lead time plus cure time before demand rises.
| Date | Days from 26 Sep | What happens |
|---|---|---|
| 26 September 2026 | 0 | Raise the reorder point to festive use; place the order if stock plus on-order is at or below it |
| 10 October 2026 | 14 | Earliest arrival (2-week lead): inspect, start pouring |
| 17 October 2026 | 21 | Average arrival (3-week lead) |
| 24 October 2026 | 28 | Latest arrival (4-week lead): pour immediately; only a short cure fits before Diwali |
| 8 November 2026 | 43 | Diwali |
For one-off festive or corporate orders, as opposed to a rising weekly rate, extras for breakage and rejects are a separate calculation: see the buffer percentage by order type and the 500-candle wedding guide.
A weekly stock routine
A reorder point only works if someone looks at the shelf. Fifteen minutes a week keeps it honest.

CandleMakingSuppliesIndia sells jars, wicks and wax, and does not sell finished candles. This guide tells you not to hold several months of our jars when a reorder point covers the risk, points out that our jar listings carry no volume price where that is true, and says plainly that we do not publish delivery times. That is deliberate: stock advice that sells you more than you need is bad advice.
