I Buy Lavender, Coffee, Rose and Oud at Different Prices — How Do I Calculate Fragrance-Specific COGS While Keeping the Same Candle Size?

Hold the candle still and move one bottle

The phrase "fragrance-specific COGS" sounds like four separate exercises and is really one. If the candle size is the same across your range — and your question says it is — then the wax, the vessel and the wick are constants, and a constant does not need costing four times. Fix them once, and the per-scent sheet becomes a single multiplication repeated down a column: grams of oil × that oil's rate per gram.

Getting the grams right is the only part with a trap in it. Fragrance load is a percentage of wax weight — that is how CSI product pages state it and it is the convention of this series — so a candle holding 200 g of wax at 8% takes 16 g of fragrance and the vessel receives 216 g, not 200 g. Sixteen grams is the figure this page carries into every table below. If your own candle is measured by finished weight instead, a 200 g fill at 8% is 185.19 g of wax and 14.81 g of oil; use that figure consistently rather than mixing the two readings inside one sheet.

With the fill fixed, the base is arithmetic you do once. 200 g of Luxury Soy Wax CSI 464 at ₹507.40 a kilogram is ₹101.48. A Green Iridescent Jar is ₹150.00. An Eco Candle Wicks Thin (C1) is ₹5.90, the same rate at the 20, 50, 100, 500 and 1000 packs. Total: ₹257.38, under every scent you will ever pour in that format. Write it at the top of the sheet and never recalculate it while you are comparing scents.

Two things in that table are worth a second look. The first is the ordering. The four scents in your question sound like a price ladder — lavender the everyday one, oud the luxury one — and the arithmetic does not agree. Woody Oud at ₹4.53 a gram sits below Lavender at ₹5.22. A scent family is a description of how something smells, not a statement about what it costs, and the only honest ranking comes from dividing each pack price by its grams. The second is the share row: fragrance is between 16.0% and 24.5% of this candle, which sets a ceiling on how much any amount of scent-shopping can ever change your cost.

The spread, stated three ways so it cannot mislead

The difference between your cheapest and dearest scent is ₹34.45 a candle. That single figure can be expressed three ways, and the three sound so different that choosing one carelessly will distort a decision. As a share of the fragrance line it is 70.2% — Lavender costs that much more to scent than British Rose. As a share of the finished cost of goods it is 11.24%. And in rupees it is ₹34.45 a candle, ₹3,444.80 across a hundred, ₹861.20 across a 25-candle run.

All three are true. The one that belongs in a purchasing conversation is the rupee figure, because that is what leaves your account. The percentage of the fragrance line is the one that makes makers panic, and it is the least useful of the three: it compares a part against a part and silently drops the ₹257.38 that both candles carry. The percentage of cost of goods is the one that belongs on the cost sheet, because it is the only version that is proportional to the thing you will eventually price.

The spread is fixed in rupees and moves as a share

If you take one thing from the percentage arithmetic, take this: the gap between two scents is fixed in rupees and completely unfixed as a percentage. It is ₹34.45 a candle whatever else you build around it, because the only thing that decides it is 16 g and two rates. But as a share of the candle it depends entirely on how expensive the rest of the candle is — which, in practice, means the vessel.

The table below runs the same two extremes against three real CSI vessels at three genuinely different price points, priced per piece. It is not a recommendation of any of them, and it is deliberately not a claim about what any of them holds: CSI publishes no fill weight for these vessels and this page will not invent one. The wax is the same 200 g throughout, so the rows are comparable as arithmetic even though the vessels are not comparable as objects.

Look at the last column. The same ₹34.45 is 16.91% of a candle in the cheapest vessel and 8.47% in the dearest. Nothing about the fragrances changed. If you report per-scent cost differences to yourself as percentages and then change vessel, the percentages will move for a reason that has nothing to do with your scents, and you will draw a conclusion about fragrance from a fact about glass. Report the rupees; derive the percentage when you need it, from that candle's own cost of goods.

Four pages, one ceiling, and one scent that will tint your wax

Everything above rests on an assumption stated once and worth testing: that 8% is a load all four of these oils can actually be used at. Two published figures govern that, and the lower of them always wins. Luxury Soy Wax CSI 464 states a maximum fragrance load of 10% of total wax weight. Each of the four oil pages states its own candle range — British Rose soy use up to 10%, Roasted Coffee 6–10% for soy, Woody Oud 6–10%, Lavender 6–10% of total wax weight. Both ceilings land on 10%, so 8% sits comfortably inside all four and the comparison is a fair one.

That agreement is convenient and it is not guaranteed. Change the wax or add a fifth scent and you may find an oil whose page publishes a narrower range, or one whose page publishes none at all — in which case the wax grade's stated maximum is the only published limit and there is no second figure to take the lower of. Say that plainly in your own sheet rather than assuming a number, and ask on WhatsApp for MSDS and IFRA documentation before committing a batch.

One line in that table has a cost consequence the arithmetic does not show. The Roasted Coffee page states that its vanilla and caramel base notes contain vanillin, which can tint pale wax over time. That is cosmetic, not a fault, and it is a known property of vanillin-carrying fragrances in general candle-making practice. It matters to a cost sheet in one indirect way: if the tint makes you reject candles that a customer would have accepted, the real cost of that scent is higher than ₹59.81 a candle. British Rose states 0% vanillin and no discolouration in white wax, which is why it is often the safe scent in a pale range. Test both in your own wax before you build a reject rate into anything.

The same table at the scale you actually pour

Per-candle figures are for comparing. Batch figures are for buying. Take the same four scents to 25 candles each — a 100-candle run across the range, which is a realistic single pour session for a small Indian maker building stock before a festive month — and the sheet turns into quantities you can order against. Each scent needs 400 g of oil and 5 kg of wax, so the run needs 20 kg of Luxury Soy Wax CSI 464 in total and 100 vessels and wicks.

The run total, ₹32,361.28 in materials from CSI, is the figure to hold against your own blank rows rather than against any of the per-candle numbers. And notice what 400 g per scent implies: it is less than a 500 gm pack and well under a kilogram, so the rates used in this table assume you are buying at kilogram pricing for a quantity you will use over several runs. That is normal and it is also a cash decision rather than a costing one, so this page states the rate it used and leaves the buying question alone.

Building the sheet for your own scents, in four steps

What a cost of goods figure is not

The four figures above are materials CSI sells, priced from live stock. They are not a full cost of goods sold and they are certainly not a product cost. Everything below is real money and none of it is a CSI product, so no honest figure for it exists on this page. Copy the rows, fill in your own, and total the sheet as materials from CSI plus your own costs.

Delivery is the blank most often treated as zero, and it is not zero. The 1 kg pack of British Rose stores a packed weight of 1.5 kg, and the cheapest published band covering that weight in September 2026 is ₹180.00 on Standard Shipping. Ordering four scents in four separate weeks pays that band four times; ordering them together pays one band for the consolidated weight. Rates are the published flat bands as at September 2026 and can change, and the linked product pages carry the stored weights.

Two of the store's own reviews say plainly that delivery charges feel high, and one says the cost at checkout was a surprise once the weight was calculated. That is fair criticism and the answer to it is arithmetic rather than reassurance: put the delivery of a consolidated order into your own blank row, divide it by the candles that order will make, and you will have a figure that belongs in your cost of goods instead of a vague sense that shipping is expensive.
