I'm Making 1,000 Jar Candles for a Corporate Order — How Much Extra Wax Should I Prepare Beyond the Exact Calculated Fill Weight?

The exact figure, and why corporate orders need more than it

The exact figure is simple. One finished candle, weighed in your jar at your fill line; in the series worked example the CSI 200 ml Matte jar holds about 150 g (how 200 ml becomes about 150 g). At 8%, 12 g of that is oil and 138 g is wax. Times 1,000: 138 kg of wax and 12 kg of oil, 150 kg of blend. At the listed prices the exact wax is ₹70,021.20 and the exact oil, with Sandalwood, ₹60,321.60.

Three things make a corporate order different from a retail run of the same size, and all three push the buffer up.

The last row is why the buffer matters more than its size suggests. If you run out and reorder, the top-up comes from a different bag, a different oil bottle and possibly a different carton of jars; mass-produced glass varies between batches. Thirty candles that look slightly different from the other 970 in a boardroom are a problem a retail customer would never see.

Four slices of corporate buffer, sized

Each slice below has one job and a size we would plan for a single-jar, single-scent corporate order of 1,000. The rates are our planning judgement, not industry data. The general loss categories and how they scale with melt size are broken down in I'm Making 500 Candles in the Same Glass Jar — How Do I Calculate Wax Requirement After Accounting for Fragrance Oil and Production Loss?; here we only size them for a corporate order.

Samples come before the buffer, not out of it

Client samples are poured weeks before you buy 160 kg, from small packs, and they decide which oil you buy fourteen kilograms of. Do not open a 10 kg bag for them. About 2 kg of wax in 1 kg bags, a 100 g bottle of each candidate oil, a pack of 10 jars and 10 wicks cover ten samples and leave room for a revision: ₹2,773.00 with Sandalwood and Woody Oud as the pair. Keep one approved candle sealed as the golden sample; every later melt is compared with it.

Replacement units are finished candles, not spare wax

If a carton arrives with two broken jars, the client wants two candles, not your promise to make them. So replacement units are poured in the same melts as the order, cured with it, and boxed with it or kept ready to send. We plan 10 as a worked example. We do not publish a breakage rate and we will not invent one: plug in your own courier experience, and read I Have a 1,000-Candle Corporate Order — How Much Additional Jar Inventory Should I Keep in Case Some Pieces Arrive Damaged? for how many extra jars to hold for a corporate order and What Percentage of Extra Candle Jars Should I Order for a Large Wedding, Diwali or Corporate Gifting Order? for extra-jar percentages by order type.

Working buffer vs sealed reserve

The working buffer is the 10 kg of blend above: it is scented, it is melted, and nearly all of it is used, because rejects, test candles, replacements and residue are all things that happen. It adds 6.7% to the wax you melt. The sealed reserve is different in kind. It is one 10 kg bag of CSI 464 and one 1 kg bottle of Sandalwood that you buy with the order and do not open unless something goes wrong: rejects run at 5% instead of 2%, a melt fails, the client adds 50 names in the last week, or a carton breaks after delivery and you have used your replacement units. That is another 7.2% of wax, which, with the 2.8 kg left in the fifteenth production bag, brings the wax on hand to 15.9% above the exact figure.

Why keep the reserve as wax and not as extra candles? Because unscented wax can become any candle, and a finished Sandalwood candle can only become a Sandalwood candle. If the reserve is never opened, the only cost is the cash tied up in one bag and one bottle until your next order.

The cost of too much vs too little

The question behind "how much extra" is really which mistake you can afford. The two are not symmetrical, and the worked example below shows why. The ₹ figures use CSI prices on 26 September 2026; the invoice price is illustrative, so plug in your own.

Two conclusions. First, the best-value insurance is unscented, because it keeps its value: the reserve bag costs ₹5,074.00 and is spent eventually either way. Second, the costly failure is running short, and most of that cost is time. A top-up order costs the same per gram as the original at CSI (CSI 464 is flat from 1 kg; Sandalwood is flat from 100 g), so you do not lose on price; you lose the days between noticing and delivering, and the batch match. Delivery times are not published; confirm them on WhatsApp before you promise a client a date.

The 1,000-candle order, costed

Everything for 1,000 delivered candles of 150 g at 8% in the Matte 200 ml jar, with the working buffer and the sealed reserve. Prices are CSI live pricing on 26 September 2026; quantities are our worked example; costs exclude labour, freight, packaging and GST.

One candle at exact grams is ₹210.58; the production bill works out at ₹225.00 per delivered candle because the thousand carry the forty extra jars, the residue and the 2.8 kg of wax left in the fifteenth bag. If the client wants lids, the Clear Glass Jar with Golden Lid (150 gram) at ₹94.40 per jar makes the 1,040 jars ₹98,176.00, ₹24,544.00 more, and needs its own weighed fill weight first. Shipping cartons such as the Corrugated 3 ply box 7 x 5 x 4 Inch (Pack of 50) at ₹1,336.00 are a packaging line, not a buffer line; plan them per delivery address.

What to buy: wax, oil, jars, wicks

Five products the order depends on, chosen on what their pages state, price and stock on 26 September 2026. The oil is a costing example; the second jar is the lidded alternative.

Running the buffer during production

Weigh a sample of finished candles before you pack: if the average has drifted from your fill weight, both the buffer and any net weight printed on the label have moved. How brands set the declared weight below the lowest candle is in How Do Professional Candle Brands Determine the Correct Net Weight to Print on the Label When Using a New Jar?; the full measurement list for a new batch of jars is in I'm Buying Candle Jars in Bulk for the First Time — What Measurements Do I Need Besides the Supplier's ml Capacity?.
