I'm Constantly Placing Emergency Raw-Material Orders — How Do I Calculate Minimum Stock Levels for Wax, Fragrance, Wicks and Jars?

Why emergencies happen

When makers describe their emergency orders, the same five stories come up. Each has a cause you can fix with a number, and none of them is solved by simply buying more of everything. Buying more of everything is how businesses end up with cash stuck in wax while still ordering wicks by express.

The first cause is by far the most common, and the rest of this page is built around it. A candle is four materials at once. If any one is missing, the other three are useless for that candle. So the question is never "do I have enough wax?" but "how many candles can I pour with what is on the shelf?" That number is set by whichever material runs out first.

One unit for four materials

The example business pours 120 candles a week: four pour days of 30 candles each. Every candle is a 200 g container candle at an 8% load: 184 g of Luxury Soy Wax Chunks, 16 g of fragrance, one Cotton Braided Wick and one White Matte Glass Jar. In calendar days, that is 17.14 candles a day. The example lead time is 6 days from noticing to usable stock, with 4 days of safety stock on top. Both are illustrations: measure your own.

The minimum is then 17.14 × (6 + 4) = 171.4, rounded up to 172 candle-equivalents. Every material gets the same minimum in candles. Converting to each material is a single multiplication by what one candle uses:

Rounding goes up, never down, and the minimum is counted in sealed packs only. An open 5 kg bag of wax with a kilo in it is not part of the minimum; it is working stock. This one rule removes the fifth cause in the table, where a maker counts an open bag as "still some left" and discovers at the pour that the last few hundred grams are not enough for a batch.

Fragrance needs one more step, because the 2,752 g is shared across scents. Split it by each scent's share of candles. If your lead scent goes into 35% of candles, its minimum is 963 g; a scent at 5% needs 138 g, which is less than a 100 g bottle, so one sealed bottle is its minimum.

The shortest-bar audit

Here is the example shelf on a Monday morning. The owner has just said they feel well stocked. Divide each material on hand by what one candle uses, then by daily usage, and the picture changes:

The wax covers 12.7 days and the jars 15.2. The lead scent, at 35% of candles, covers 11.5 days of its share. The wicks cover 5.2 days, below the 10-day minimum and below even the 6-day lead time. If the owner orders wicks today, they arrive with nothing to spare; if they wait for their usual Friday order, they will be placing an emergency order by Thursday. Nothing about the wax or jars helps. The business's real capacity this week is 90 candles, not 217.

What emergencies really cost

An emergency order has two costs. The visible one is the extra delivery charge for a small, rushed order. The invisible one is the pour day you lose waiting for it. Both are your figures, and the ones below are examples to replace. Say you place 2 emergency orders a month, each with an example delivery charge of ₹150.00, and each costs half a pour day, 30 candles, with an example contribution of ₹200.00 per candle that you would otherwise have earned and do not make up later.

The comparison is lopsided because the fixes are one-off and the emergencies repeat. Raising the wick minimum by 100 ties up ₹1,200.00 of cash, permanently, which at any reasonable cost of money is a few rupees a month. The emergencies it prevents cost ₹3,600.00 a year in delivery charges alone in this example. Where the fix is expensive, as with jars at ₹70.80 each, the case is closer, and the right answer is a tighter review habit rather than a much bigger shelf.

This is also why minimums should not be the same number of days for every material. Cheap, compact, non-perishable items can carry more days: wicks at ₹12.00 each or Eco Thin C1 at ₹5.90 each cost little to over-hold. Bulky or expensive items, like jars and wax, should sit close to the formula.

A minimum-stock card system

The simplest system that works is a card on the front of every sealed minimum. It needs no software and cannot be forgotten, because the trigger is physical: you cannot open the minimum without reading the card.

Each card carries four lines: the material, the minimum in packs (for example "7 × 5 kg"), what to order when this is opened (for example one month of usage), and the date the minimum was last recalculated. When a sealed pack from the minimum is opened, the card goes on a hook by the door or a photo goes into your ordering chat. On order day, every card on the hook is ordered together in one order, which is how emergencies turn back into routine orders.

Recalculate the minimums on the first of each month from the previous month's candles poured. If you are growing, use this month's forecast instead, as I'm Growing Quickly but Don't Want to Run Out of Wax — How Do I Set a Reorder Point Based on Monthly Consumption and Supplier Lead Time? explains.

And if one material keeps landing on the hook weeks before the others, I'm Running Out of One Raw Material While Having Months of Another — How Do I Synchronise Wax, Fragrance, Wick and Jar Purchasing with Actual Production? shows how to line their cycles up so they are reordered together.

Non-CSI items belong on the same system. Lids, labels, boxes and tape stop an order leaving the door just as surely as a missing wick stops a pour. Give each the same candle-based minimum. Their prices are your suppliers' quotes, not ours; the arithmetic is the same.
