My Wax Supplier Offers a 25 Kg Price Break — How Many Candles Do I Need to Sell Before the Larger Purchase Meaningfully Reduces My Cost Per Unit?

A rate break does not wait for a volume

Take the question at face value first. Your supplier quotes a lower rate per kilogram at 25 kg. That rate is a property of the wax you now own, not a reward that unlocks later. Divide the invoice by the kilograms, multiply by the 0.2 kg in a 200 g candle, and that is your wax line from the very first pour. If somebody has told you that a break only starts paying after a certain number of sales, they have quietly substituted a different question — usually a good question, but a different one.

The three real questions hiding inside yours are worth separating, because they have different answers and different sizes. Conversion: a saving is only banked on wax that becomes a sold candle, and 25 kg at 200 g is 125 candles. Cash: those 125 candles' worth of wax has to be paid for on day one and released one candle at a time. Carriage: 25 kg is heavy enough that how it travels costs more than what it cost. This page takes them in that order, and it uses one fill reading throughout — 200 g of wax plus 16 g of oil at 8% of wax weight, 216 g poured — because a load stated as a percentage of the finished candle would change every candle count on the page.

One quantity that gets forgotten in every 25 kg conversation: the fragrance. At 8% of wax weight, 25 kg of wax needs 2.0 kg of oil to become 125 scented candles. If you buy the wax and not the oil, you have committed to a production plan you cannot yet execute; if you buy both, the cash number roughly doubles on most fragrance rates. Decide both together or neither.

On this store, the ladder is finished by 5 kg

CSI publishes no quantity-discount ladder as a policy, and reading the live variants grade by grade gives a sharper fact than that. Where a rate does move, it has finished moving by the 5 kg pack. Luxury Soy Wax CSI 464 is ₹520.00 a kilogram in the 500 g pack and ₹507.40 in the 1 kg pack and in every pack above it. Natural Soy Pearl Wax is ₹450.00 at 1 kg and ₹424.80 at 5 kg and above. Premium Coconut Soy Wax CSI 468 is ₹650.00 at 500 g and at 1 kg, and ₹637.00 at 5 kg and above.

Five kilograms of wax is 25 candles at 200 g. So on this store the honest answer to “how many candles before the larger purchase reduces my cost per unit” is 25 — and it is 25 because that is where the ladder ends, not because anything improves after it. Buying 25 kg rather than 5 kg changes your rate by ₹0.00 on all three of those grades. Whatever a 25 kg commitment buys you here, it is not a lower rate per kilogram.

One grade runs the other way, which is worth knowing before you scale up a favourite. Luxury Soy Wax Chunks is ₹598.00 a kilogram in the 500 g pack and ₹599.90 in the 10 kg pack. Buying 25 kg of it in the largest packs comes to ₹14,993.00; buying the same 25 kg as fifty 500 g packs comes to ₹14,950.00 — ₹43.00 less, or ₹0.34 a candle. That is a trivial sum, and that is the point of quoting it: on a store with flat ladders, the difference between the best and worst way to buy 25 kg of wax is under a rupee a candle, while the difference between the best and worst way to ship it is nearly fifteen.

Deciding what “meaningfully” means, in rupees

“Meaningfully” is your word, and it is the right one, because a step of a few paise a candle is arithmetically real and commercially invisible. Give it a rupee value you would actually notice — say ₹1,000.00 a month — and the volume question becomes answerable: divide your threshold by the per-candle step and you have the number of candles a month that step has to carry before it earns its place in a decision.

Run it on CSI's own published steps, since your question supplies no rates of its own. The steepest is Natural Soy Pearl Wax at ₹5.04 a candle; at that step you would need 199 candles a month before it is worth ₹1,000.00 to you. Premium Coconut Soy Wax CSI 468 at ₹2.60 a candle needs 385. Now put the routing saving from this page's last section on the same scale: ₹6.96 a candle needs only 144. That comparison is the whole argument for reading a delivery profile as carefully as a price list.

What 125 candles of wax does to your cash

Twenty-five kilograms of Luxury Soy Wax CSI 464 is ₹12,685.00 at September 2026 pricing. The same money buys five 5 kg packs at ₹2,537.00 each, and those can be bought one at a time, which is the real difference between the two plans. Not the rate, which is identical, but when the money leaves. Spreading the purchase across a quarter keeps roughly four fifths of it available for jars, a festive fragrance, or the order that arrives when you are out of stock.

Spoilage is not the risk here, which is worth saying plainly so you can weigh the right thing. The Luxury Soy Wax CSI 464 page states a shelf life of 60 months in cool, dry storage away from sunlight and moisture — longer than any sales plan you are making today. The risk with 25 kg is commitment: you have chosen your wax grade for the next 125 candles, and if a burn test six weeks from now tells you a different grade suits your fragrance load better, the sack does not care.

The 25 kg decision that is actually worth money

CSI charges flat rates by weight band and a parcel bills on its stored packed weight, not on the number on the label. Twenty-five kilograms of Luxury Soy Wax CSI 464 bought as two of the largest packs and one 5 kg pack presents 11.0 kg, 11.0 kg and 6.0 kg — 28.0 kg if it all goes in one consignment. The cheapest published band covering 28.0 kg is the 25–35 kg Expedited one at ₹3,500.00.

Now try it as two. Put the two largest packs together and they present 22.0 kg, whose cheapest covering band is the 20–25 kg Expedited one at ₹2,000.00. Send the 5 kg pack on its own and it presents 6.0 kg, covered by the 5–7 kg Standard band at ₹630.00. The pair comes to ₹2,630.00 — ₹870.00 less than the single consignment, or ₹6.96 across 125 candles. Three parcels, one per pack, would be ₹3,030.00, so two is the right number rather than as many as possible. Every figure is a published September 2026 flat band and can change.

Put the worst routing beside the best and the size of this becomes hard to ignore. Twenty-five kilograms bought a kilogram at a time across twenty-five separate orders bills ₹4,500.00, because each 1 kg pack presents 1.5 kg packed and falls in the 1–2 kg Standard band at ₹180.00. Against ₹2,630.00 for the two-parcel plan, that is ₹1,870.00, or ₹14.96 a candle. The entire quantity prize CSI's steepest published wax ladder offers across the same 25 kg is ₹630.00. The routing is worth about three times the ladder.

The Chunks rows make the same point with different weights, which is the best evidence that this is a rule rather than a coincidence. Its largest pack stores 12.0 kg and its 5 kg pack stores 5.0 kg, so 25 kg presents 29.0 kg as one consignment at ₹3,500.00 and 24.0 kg plus 5.0 kg as two parcels at ₹2,450.00 — a difference of ₹1,050.00, or ₹8.40 a candle. Different grade, different packed weights, same answer: past 15 kg, adding the bands for two parcels is usually cheaper than paying one band for the lot.

What this page will not put a number on

CSI sells raw materials and publishes its delivery rates, so the wax line, the fragrance line, the wick line and the carriage can all be quoted from a live store. Nothing below is a CSI product. A 25 kg purchase changes several of them — storage most obviously — and putting a plausible-looking figure in a blank would quietly turn this page's arithmetic into a forecast. Copy the rows, fill them in yourself, and total the sheet as materials from CSI plus your own costs.

One of those blanks changes size specifically because of this decision, and it is the storage row. Five kilograms of soy lives in a cupboard. Twenty-five kilograms needs somewhere dry, off a concrete floor, out of direct sun, and sealed — which in a coastal Indian August is not a trivial requirement, and in a Delhi May means keeping it away from a west-facing wall. Decant into containers you can actually lift. The wax will keep for years if you treat it properly and clump within a monsoon if you leave the sack open, and either outcome dwarfs the ₹630.00 a quantity step was ever going to be worth.
