I'm Making 100 × 200 g Candles at 6% Fragrance — Should I Buy a 1 Kg Fragrance Bottle or Will I Need More?

Why 1 kg falls short

The calculation uses CSI's convention: load is a share of the finished candle. A 200 g candle at 6% contains 200 × 0.06 = 12 g of fragrance oil and 188 g of wax. Multiply by the order and you have the net requirement. Because 6% is a lighter load than the 8% used in most of our examples, it is easy to assume one kilo will stretch. The table shows why it does not.

The last row is the practical one. If you start the run with a single kilo, you will reach roughly candle 78 to 83 with an empty bottle, depending on how much stays in the jug. The remaining candles either wait for a second delivery or get poured at a lower load, and neither is a good outcome when all hundred are going to the same customer.

About the allowances. The 3% pour allowance and the two test candles are working assumptions. Makers commonly plan 3–5% extra for pour loss and test burns. Three percent suits a careful bench batch, and 5% suits a larger pot, a funnel or a lot of top-ups. At 5%, the bench figure becomes 1,284 g, and the cheapest Lavender cover moves up with it. Two test candles is a minimum for an oil you have already used in this wax. For a new oil, plan a proper test round; the testing allowance post sizes one for a 100-candle order.

Load against the bottle

Because the oil requirement scales directly with load, the same hundred candles need a different amount of oil at every load. Here is the order at four loads, with the same two allowances, compared against a single 1 kg bottle:

A single kilo only covers a hundred 200 g candles at 5%, and then with nothing to spare: 1,000 g net, 1,050 g once the pour loss and two 10 g tests are added. At 6%, the load in the title, it falls short at every stage. At 8%, the default working load across CSI's guides, the order needs 1,600 g net and 1,680 g with allowances, which is the 100 × 200 g at 8% calculation. At 10% it needs 2,000 g net, covered in the 10% post.

The reverse trap also exists. A maker who decides mid-run that 6% is too weak and raises the last thirty candles to 8% has made two different products under one label. Decide the load in testing, then buy for that load. If you are not sure, buy for the higher of the two loads you are testing. A spare 100 g bottle is cheaper than a stalled order.

Six ways to buy 1,260 g

Lavender's listed per-gram prices are ₹7.00 at 15 g, ₹5.40 at 50 g and 100 g, ₹5.24 at 500 g and ₹5.22 at 1 kg. The only real step is at 15 g. Every option below is priced from the in-stock listing pulled on 24 September 2026:

Option C is the cheapest cover at ₹6,676.02. It uses a 15 g bottle for the last 5 g, which carries the 15 g premium (₹7.00 a gram) but is still cheaper than a whole extra 50 g. Option D, the kilo plus three 100 g bottles, costs ₹164.98 more and gives 35 g more headroom in four bottles instead of five. If your pour allowance turns out closer to 5%, D is the one that still covers the run. Option E, the kilo plus a 500 g, costs ₹1,164.98 more than C and leaves 240 g spare, enough for 20 more candles at 12 g. Option F, two kilos, leaves 740 g spare, about 61 candles' worth, and only makes sense if the next Lavender order is already booked.

The same order on other oils gives different answers, because each oil has its own price ladder. Two contrasting examples:

Cinnamon is one of the oils where the kilo is about 10% cheaper per gram than the 100 g, so the top-up bottles are relatively dearer (₹5.90 a gram against ₹5.31). Its cheapest cover uses four 15 g bottles for the last 60 g, which on its listed prices costs less than a 50 g plus a 15 g. For Cinnamon, ask on WhatsApp whether a quantity between 1 kg and 2 kg can be quoted; no discount figure is published, so ask rather than assume. Japanese Cherry Blossom sits between the two: ₹5.00 a gram at 100 g, ₹4.84 at 1 kg.

The convention check

Before you order, confirm which "6%" you mean. CSI's figures are a share of the finished candle. If you take 6% of the wax instead, 18,800 g of wax × 0.06 gives 1,128 g of oil, a true load of 5.66%. Notice that even this lower figure is more than one kilo. Either way, the answer to the title is the same: one 1 kg bottle is not enough for this order.

If your approved test candle was made with 6% of the wax weight, keep making it that way, but know that your real load is 5.66% and write that on the batch sheet. The point is not which convention is right. It is that the test candle and the production run use the same one. The 50-candle weighing guide explains the trap in detail.

The priced 100-candle order

That is ₹267.39 per saleable candle in raw materials. It excludes labour, packaging, freight and GST. Fragrance is only ₹66.76 of it at 6%, which is one reason a 6% candle can be priced competitively, but it is also why running short of oil is such a poor trade: the ₹1,455.02 top-up protects a ₹26,739 order. The wax, at 6%, is well within the Chunks' stated 13% ceiling. Wick size for your jar diameter is not published, so confirm it with a burn test before the run.

Two further checks before you pay. First, confirm every size you are counting on is in stock on the product page; the table on this page reflects 24 September 2026. Second, weigh one test candle after it sets. If your jars actually take 190 g rather than 200 g, the whole calculation shrinks by 5%, and if they take 210 g it grows. Filling jars from a tested fill weight shows how to run the order from a measured fill instead of a nominal one.
