My Fragrance Oil Costs ₹500 for 100 g but ₹4,000 for 1 Kg — How Much Do I Save Per Candle by Moving to the Kilogram Pack?

₹1.00 a gram, and why that is the only number to keep

Pack prices are not comparable and rates are. ₹500.00 for 100 g and ₹4,000.00 for 1 kg look like different kinds of number until you divide each by its grams: ₹5.00 a gram and ₹4.00 a gram. Those are your supplier's figures, used here exactly as you wrote them and never presented as CSI prices. The step between them is ₹1.00 a gram, which is the happiest possible coincidence for a costing page, because it means the saving on any candle is simply the grams of fragrance in it.

Fragrance load in this series is a percentage of wax weight, which is how CSI product pages state it, so a 200 g pour of wax at 8% carries 16 g of oil and 216 g goes in the jar. At ₹1.00 a gram that is ₹16.00. Change either the size or the load and the saving moves with the grams, not with the candle: a 100 g wax pour at 8% is 8 g and ₹8.00; the same 200 g pour taken to 10% is 20 g and ₹20.00; a 300 g pour at 10% is 30 g and ₹30.00. Nothing else on the candle moves at all — the wax, the wick and the vessel cost exactly what they cost whichever bottle the fragrance came out of.

The cash side deserves a line before we go further. The kilogram costs ₹3,500.00 more on the day than the 100 g pack does, and it commits that money to one scent. A kilogram at 16 g a candle is 62.5 candles of a single fragrance. If it is your bestseller, that is a sensible use of ₹4,000.00. If it is a scent you launched last month, the 100 g pack is the cheaper mistake, and the ₹16.00 a candle you gave up is the price of finding out.

The same move on CSI's own oils, one at a time

CSI publishes no quantity-discount ladder as a policy, and reading the live variants oil by oil shows why that matters more than a policy would. Each of the 92 fragrance pages carries its own ladder, and the ladders do not all point the same way. Here is the identical move — 16 g of oil bought at the 100 g pack rate against the 1 kg pack rate — on five of them, with the cheapest published rung named where it is neither.

Read the Sage and Cedarwood row slowly, because it is the whole argument of this page in one line. Its 500 gm pack works out at ₹5.17 a gram and its 1 kg pack at ₹6.87 a gram. Buy a kilogram of it as two 500 gm packs and you pay ₹5,168.40; buy it as one kilogram pack and you pay ₹6,867.60. Identical contents, ₹1,699.20 apart, and the larger pack is the dearer one. Per candle at 16 g that is ₹27.19 — more than your whole stated step is worth, pointing the wrong way.

Spicy Raspberry makes a quieter version of the same point. Its 50g pack is ₹5.98 a gram and its 1kg pack is ₹6.00 a gram, so the kilogram is ₹0.14 a candle dearer — a difference so small it barely matters commercially and matters enormously as a habit, because it tells you the ladder cannot be assumed. And the other direction is just as real: Citronella runs ₹7.67 a gram at 100 gm and ₹2.89 at a kilogram, a fall of ₹76.46 on one candle, which is nearly five times your own step.

Reading an oil ladder in thirty seconds

The saving the pack change is usually standing in for

CSI charges flat rates by weight band and bills on the stored packed weight, not on the grams on the label. A 100 gm pack of British Rose stores 0.2 kg packed, a 500 gm pack stores 0.8 kg and the 1 kg pack stores 1.5 kg. A fragrance bottle ships far heavier than it weighs, and that is where most of the money in this decision actually sits.

Buy a kilogram of that oil a hundred grams at a time, across ten separate orders, and each parcel falls in the 0–0.5 kg Standard band at ₹80.00: ₹800.00 in total. Buy it as one kilogram pack and the parcel bills ₹180.00. The difference is ₹620.00, which across the 62.5 candles that kilogram scents is ₹9.92 a candle. Set that beside your own pack step of ₹16.00 and it is not a footnote, it is most of the prize.

And here is the honest qualification, because it changes what you should actually do. Ten 100 gm packs ordered together weigh 2.0 kg packed and fall in the 1–2 kg Standard band at ₹180.00 — the same as the single kilogram pack. So the ₹620.00 is a reward for placing one order rather than ten, not for choosing the big bottle. The same applies to Sage and Cedarwood: two 500 gm packs store 1.6 kg together and bill ₹180.00, exactly what the 1 kg pack bills at 1.5 kg. You can collect its ₹1,699.20 rate advantage and pay nothing extra to carry it.

Before you take “consolidate everything” as the lesson, check the direction, because the bands punish that too. Standard Shipping stops at 15 kg. Three 1 kg oils store 4.5 kg between them and one 10 kg pack of Luxury Soy Wax CSI 464 stores 11.0 kg, so together they present 15.5 kg — just past the edge, into the 15–20 kg Expedited band at ₹2,400.00. Sent as two consignments the oils bill ₹450.00 in the 4–5 kg Standard band and the wax ₹1,200.00 in the 10–15 kg Standard band, ₹1,650.00 for the pair. Splitting is ₹750.00 cheaper. Add the stored packed weights, look up the band, then look up the two bands a split would use, and take the smaller number.

Before the kilogram: check the ceiling, not just the rate

Every figure on this page assumes 16 g of oil on 200 g of wax, which is 8% of wax weight. That is comfortably inside what the pages state for most of these oils, but the check is worth making before you commit to a kilogram, because a load you cannot use is a rate you cannot collect. Two published figures apply: the wax grade's stated maximum and the oil page's stated candle range. Where they differ, the lower one governs. Luxury Soy Wax CSI 464 states a maximum of 10% of total wax weight; the British Rose page states soy use up to 10%, the Citronella page up to 10%, the Sage and Cedarwood page up to 10% for soy and up to 6% for paraffin, and the Mango Coconut page 6–10% of total wax weight for soy candles.

One of the five behaves differently and it is worth stating exactly rather than guessing. The Spicy Raspberry page publishes no candle usage range at all. Where an oil page publishes no range, the wax grade's stated maximum is the only published limit — so on Luxury Soy Wax CSI 464 that is 10% of total wax weight, and there is no second figure to take the lower of. Ask on WhatsApp for the documentation before you buy a kilogram of any oil whose page does not print a range, and burn-test at your own load before you scale.

The load matters commercially as well as technically, because the saving scales with it. At 8% of 200 g your step is worth ₹16.00 a candle; at 10% it is worth ₹20.00. That is a reason to settle the load first and cost second, never the other way round. A load chosen to make a fragrance cost calculation look better is a load chosen for the wrong reason, and it shows up in a burn test as sweating, a drowned wick or a sooty flame long before it shows up on a margin sheet.

What this page will not put a number on

This page prices one line of a candle — the fragrance — plus the published cost of getting it to you. That is deliberate: it is the only line your question is about, and it is the only line a pack change moves. Everything below is either a cost CSI does not sell or a figure only you can supply. Copy the rows, fill them in, and total the sheet as materials from CSI plus your own costs.

The residue row is the one worth measuring, because it is the only line on that list that a kilogram pack genuinely changes. A 100 g bottle leaves a film behind, and ten of them leave ten films; one kilogram bottle leaves one. Nobody publishes a figure for that and this page will not invent one, but weigh an empty bottle against a full one on the same scale once and you will have your own number — which at ₹4.00 a gram on your figures, or ₹3.07 a gram on British Rose, is worth knowing before you decide that small packs are harmless.
