My Soy Wax Costs ₹550 Per Kg and Lavender Fragrance Oil Costs ₹3,500 Per Kg — How Much Does the Scented Wax Inside One 150 g Candle Actually Cost?

What “the scented wax” is, and why costing it on its own is worth doing

A candle has a vessel, a wick and a mixture, and only the mixture behaves like a recipe. Change the jar and the vessel line changes. Change the diameter and the wick line changes. The mixture — wax plus oil at a stated load — has one cost per gram that holds across your whole range, and pulling it out as its own figure is the single most useful thing you can do to a candle cost sheet. That is what this page costs, and it deliberately stops there.

Two of the three inputs came with your question: wax at ₹550.00 a kilogram and lavender fragrance oil at ₹3,500.00 a kilogram. Those are your rates, kept exactly as written, unrounded, and never treated here as CSI prices. The third input, the load, you did not give. This page uses 8%, which is the middle of the 6–10% of total wax weight that the Lavender Fragrance Oil page states for soy candles. It is a published range rather than a guess, and if you work at 6% or 10% the method below is unchanged — only the multiplier moves.

Which leaves the sentence "one 150 g candle", and it has two honest readings. It can mean 150 g of wax, in which case 8% adds 12 g of oil and 162 g of scented wax comes out of your jug. Or it can mean 150 g of finished scented wax, in which case the wax has to come down to make room for the oil. This page carries the first reading — 150 g of wax, 12 g of oil, 162 g of mixture — and states it in every table. The second is costed beside it so you can take whichever is yours.

The one line that produces the rate

Look at the last two rows of that table again. The totals differ by ₹9.22; the rate does not differ at all. That is not a coincidence and it is not an approximation. A gram of 8% mixture is made of the same proportions whether you pour 10 g of it or a kilogram, so it has one price. Written out: a gram of mixture is 1 ÷ 1.08 grams of wax and 0.08 ÷ 1.08 grams of oil, which rearranges to (wax ₹/g + load × oil ₹/g) ÷ (1 + load).

On your figures that is (₹0.55 + 0.08 × ₹3.50) ÷ 1.08 = ₹0.77 a gram of scented wax. Every other rupee figure on this page is that number multiplied by a weight. 162 g gives ₹124.50; 150 g gives ₹115.28. Nothing else needs to be derived again until a price changes or you change the load.

The same 162 g on materials you can buy today

Your rates may well be good ones, and on this pairing they are. Here is the identical calculation — 150 g of wax, 12 g of oil at 8%, 162 g of mixture — run on live CSI stock in September 2026. The wax is Natural Soy Pearl Wax, bought as the 1 kg pack at ₹450.00, which is ₹450.00 a kilogram. The fragrance is Lavender Fragrance Oil, bought as the 1 kg pack at ₹5,221.00, which is ₹5.22 a gram.

Read that honestly, because the total goes the wrong way for a supplier's page. The wax line falls: Natural Soy Pearl Wax at ₹450.00 a kilogram is ₹100.00 a kilogram under your rate, worth ₹15.00 on 150 g. The fragrance line rises: Lavender Fragrance Oil at ₹5.22 a gram is ₹1,721.00 a kilogram over your rate, which on only 12 g is ₹20.65. Twelve grams of the dearer material beat 150 g of the cheaper one, and the net is ₹5.65 more on the CSI pairing. That is the arithmetic; it is not an argument for either side.

What it is an argument for is comparing oils by cost per finished candle at the load each one actually needs, rather than by price per kilogram on a listing. A lavender that holds a room at 6% is cheaper per candle than one that needs 10%, whatever the two kilogram prices say — the live guide to comparing oils by cost per finished candle sets out the test. If your ₹3,500.00/kg lavender gives you the cold throw and the hot throw you want at 8%, it is doing its job and this page is not going to tell you to replace it. If it needs 10% to be heard, re-run the sum at 10% for both oils before you decide.

Where the rate actually moves: pack sizes and parcels

Costing exercises usually end with someone reaching for a bigger pack, so it is worth being exact about what that does here. Across CSI's wax range the rate per kilogram is the same at every pack size on most grades, and on a few it is slightly higher in the larger pack. Natural Soy Pearl Wax is one of the two exceptions that genuinely move: ₹450.00 for 1 kg is ₹450.00 a kilogram, and ₹2,124.00 for 5 kg is ₹424.80 a kilogram. That is ₹25.20 a kilogram, or ₹3.78 on a 150 g candle. The 10 kg and 50 kg packs sit at the same ₹424.80 a kilogram as the 5 kg, so the move worth making is the first one.

The fragrance ladder is shaped differently. Lavender Fragrance Oil runs ₹7.00 a gram at 15 gm, then ₹5.40 at 50 gm and again at 100 gm, ₹5.24 at 500 gm and ₹5.22 at 1 kg. Almost the whole of it is collected in the first step, from the 15 gm trial size to the 50 gm: after that the rate barely moves. In candle terms, going from the 100 gm pack to the kilogram takes ₹2.15 off a 150 g candle, and going from 500 gm to the kilogram takes ₹0.23. Other oils on the store behave differently — check the ladder on the one you buy rather than assuming a pattern.

What the ₹124.50 deliberately leaves out

₹124.50 is the mixture and nothing else, and that is a feature rather than an omission: the vessel and the wick change with every product in your range, while the mixture rate does not. Add them as their own lines when you cost a finished product — the live guide to wax, fragrance, wick, jar and packaging cost per candle walks the whole bill. CSI sells wax, fragrance, vessels and wicks, so all four can be priced from a live store whenever you need them. Nothing below that line is a CSI product, which means no honest number for it exists on this page.

Two blanks are worth a paragraph of their own. Wastage is not a figure this page will invent, and it is not zero: wax clings to the jug and the thermometer, a pour is abandoned, a wick sits crooked and the candle becomes a second. Assuming none makes ₹124.50 a floor. Measure it across one full batch — the wax you started with against the candles you finished with — and the percentage you get is worth more than any figure quoted online. Your labour is the line makers leave blank longest, and leaving it blank is a decision rather than a neutral act: a candle holding ₹124.50 of mixture and forty minutes of a Sunday is not a ₹124.50 candle.

One last honest note on the load. Natural Soy Pearl Wax does not publish a maximum fragrance load on its product page, so this page does not state one for it. The governing published figure on this pairing is the Lavender Fragrance Oil page's 6–10% of total wax weight for soy candles, and the 8% used throughout sits in the middle of it. Where a wax ceiling and an oil range differ, it is the lower of the two that binds. Before working above the oil's stated range on any pairing, ask on WhatsApp and burn-test the result — the cost sheet will not tell you that a load is too high, but a sweating candle in an Indian May will.
