I'm Making Small Batches of 10 Candles and My Cost Per Unit Seems High — How Much Could the Cost Change When I Produce 100 or 500 at Once?

What actually moves when the batch grows

Before any arithmetic, fix the unit. This page costs 200 g of wax at an 8% fragrance load, which on the series convention means 16 g of oil and 216 g poured — the load is a percentage of wax weight, not of the finished candle. The vessel is priced per piece and this page does not claim a 216 g fill fits it; measure your own jar with water to your wax line before you trust any capacity. The batch sizes — 10, 100 and 500 — are yours, from your question.

Now the five lines of a unit cost, and what each does when the batch grows. Wax does nothing: Luxury Soy Wax CSI 464 is ₹507.40 a kilogram in the 1 kg, 5 kg and 10 kg packs and ₹520.00 a kilogram in the 500 g pack, so 200 g costs ₹101.48 whether you buy one kilogram or ten. Fragrance moves the wrong way on this oil: Spicy Raspberry is ₹5.99 a gram in the 100 gm pack and ₹6.00 a gram in the 1 kg, so 16 g costs ₹0.14 more in the bigger pack. The vessel is where a real step exists: ₹40.12 a piece in the 5 pack against ₹29.50 in the 100 pack, ₹10.62 a candle. The wick is flat at ₹5.90 at every pack size from 10 to 1,000.

That is the whole of the price-list story, and it comes to ₹10.48 a candle between ten and a hundred. If you were expecting scale to take twenty or thirty rupees off the materials, the honest answer is that on this store it does not, because most wax and oil ladders here are the same rate at every pack size. The money is elsewhere, and the rest of this page is about where.

The fragrance line, and the pack that is cheapest per gram

Run the ladder on Spicy Raspberry and it does not behave the way scaling stories say it should. The 15g pack is ₹6.60 a gram. The 50g pack is ₹5.98 a gram — the lowest rate on the whole ladder. The 100g is ₹5.99, the 500g is ₹6.00 and the 1kg is ₹6.00. In other words, everything from 50 g upward sits within two paise a gram of everything else, and the largest pack is not the cheapest one. Sixteen grams of oil costs ₹95.68 at the 50g rate and ₹95.98 at the 1kg rate.

That does not make the 50 g pack the right purchase for a hundred-candle batch. A hundred candles need 1.6 kg of oil, and buying that in 50 g packs means thirty-two of them, thirty-two seals to open and thirty-two chances to lose a gram. The 1 kg pack is the sane purchase and it costs ₹0.14 more a candle than the 100 gm rate. The point is smaller and more useful: check the ladder on the oil you actually buy, because on this store the per-gram rate is flat from 50 g upward on most oils and a handful are dearer in the largest pack. Never assume the big pack is the cheap one.

One more honest note about this particular oil. Spicy Raspberry does not publish a candle usage range, a flash point or an IFRA claim on its product page, so this page does not state one — ask on WhatsApp if you need the documentation. The 8% used throughout sits inside the stated maximum of 10% of total wax weight for Luxury Soy Wax CSI 464. Where a wax ceiling and an oil range differ the lower one governs; here only the wax ceiling is published, so it is the one to work to, and a test burn at your own load is the only thing that settles it.

Freight per candle, which is the real small-batch penalty

Inbound freight is a flat rate by weight band, so it divides across whatever the parcel contains. A ten-candle batch needs 2 kg of wax and 160 g of oil: two 1 kg packs of Luxury Soy Wax CSI 464 and two 100 gm packs of Spicy Raspberry. Those bill at their stored packed weights, not their label weights — 1.5 kg each for the wax and 0.1 kg each for the oil — so the parcel is 3.2 kg and the cheapest published band covering it is ₹360.00 on Standard Shipping. Across ten candles that is ₹36.00 a candle.

A hundred-candle batch needs 20 kg of wax and 1.6 kg of oil: two 10 kg packs at 11 kg packed each and two 1 kg oils at 1.1 kg each, a 24.2 kg parcel. Standard stops at 15 kg, so the cheapest band that covers it is ₹2,000.00 on Expedited Shipping — more than five times the rupees for ten times the candles, which is ₹20.00 a candle. That single line is ₹16.00 of your saving, and it is the part of small-batch economics nobody puts on a cost sheet.

Two consequences worth taking seriously. First, the glass travels separately in weight terms: a 100-piece jar pack alone stores 110 kg of packed weight, which is above every published band, so the freight on a hundred jars is a conversation rather than a checkout figure. Second, splitting an order costs money. Ordering wax this week and oil next week means two parcels in two bands instead of one, and the difference is real on every split. Several customers have said on the store that these charges feel high; that is fair criticism, and consolidating into one order is the honest answer to it rather than leaving the line out of the sheet.

Test candles and wastage: the lines that shrink fastest

This page assumes two test candles per batch, whatever the batch size, and that each of them costs the full unit materials figure. That is an assumption, stated as one, not measured data — use your own number. On that assumption the testing line is ₹48.67 a candle at ten, ₹4.66 at a hundred and ₹0.93 at five hundred. It is the single biggest mover in the whole comparison, worth ₹44.01 between your ten and a hundred, and it falls not because anything got cheaper but because the same two candles are divided by more units.

Wastage behaves the same way for a different reason. Wax left in the jug, a pour abandoned, a jar chipped: a good deal of that is fixed per session rather than per candle, so a small batch carries it badly. This page assumes 5% at ten candles, 3% at a hundred and 2% at five hundred, applied to the wax and oil lines only — the jar and wick do not evaporate. Those three percentages are assumptions chosen to show the shape of the effect, not measurements, and replacing them with your own is the single most valuable thing you can do to this table. On these figures the wastage line is ₹10.39, ₹6.11 and ₹4.03 a candle.

Working out whether the bigger batch is worth it

The shape of the answer, once the arithmetic is done, is usually this. Moving from ten to a hundred is worth doing when you can sell a hundred inside a season, because ₹74.76 a candle is 22.09% of your unit cost and most of it is money you are currently burning on freight and testing. Moving from a hundred to five hundred does almost nothing to the unit cost on these packs — ₹243.63 to ₹237.83 before freight — and buys a large inventory position in one scent and one vessel instead. That is a sales decision, not a costing one, and this page will not pretend otherwise.
