I Have to Produce 5,000 Candles in the Same Jar — How Do I Calculate Wax, Fragrance, Wick and Jar Requirements Including Reasonable Wastage?

The 5,000-candle bill of materials

The scenario: a retail or corporate client wants 5,000 identical candles in one jar, one scent, over a production run of several weeks. You choose the 200 ml Salsa Glass Jar because it arrives with its own golden lug cap, Orchard Pear at 8% as a value fruit scent, and Luxury Soy Wax CSI 464, rated up to 10% fragrance load (the wax maker's stated formulation maximum). CSI doesn't publish a fill weight for the jar. We use 170 g of finished candle as a working assumption — plausible for 200 ml of soy poured below the rim — and show later what 160 g and 180 g do.

That's ₹173.64 of CSI materials per sellable candle, with the 20 test candles and every wastage line spread across the 5,000 your client pays for. On pack rates alone — oil and wax at the listed per-kilo prices, one jar, one wick, one sticker — a candle costs ₹168.10; the difference is the tests and wastage. Labels, outer boxes, labour, freight and GST are yours to add. Which costs fall with volume is the next question most clients ask at this size.

The 20 test candles are four per thousand: two approval and reference candles at the start, then burn tests spread through the run so a drift in wick, fill or scent shows up while there is still time to correct it. They are counted before any wastage percentage, because they are candles you decided to make, not losses.

Reasonable wastage, material by material

One flat percentage across the whole list is the most common shortcut and the most common source of shortfalls. Materials fail in different ways, so each gets its own rate. All of these are working assumptions for planning — the usual guide is to plan 3–5% extra for pour loss and test burns on oil and wax — and your own records should replace them.

Soy wax that goes into a faulty candle is usually recoverable — in general practice a sunk or cracked-surface candle can be re-melted into the same scent — so wax wastage is mostly residue, not rejects. Glass is the opposite: a cracked jar is gone. That's why jars get a count-based allowance (75 jars here) and why it's worth inspecting every carton on arrival rather than on the day you pour.

Going from 3% to 5% on oil and wax adds ₹13,217.00. On a first run at this scale, especially poured by hand, 5% is defensible. On a repeat run with a melter and measured losses, 3% or even 2% is realistic. Buffers for a strict delivery date covers the separate question of spare stock against supplier delays.

One gram per candle is five kilos

Ten grams of fill moves this run by about 47.6 kg of wax and 4.1 kg of oil — together ₹40,322.00. That's more than the whole 3% wastage line on oil. So the order of work is: weigh the fill first, set the wastage second. Fill one jar to the line you will sell, let it set, weigh it, subtract the empty jar with its cap off.

Which wax at 800 kg?

At 809 kg, wax is the biggest line on the bill, and the per-kilo price matters more than anywhere else in the cluster. CSI's three container soy waxes price very differently at this volume:

Natural Soy Pearl would save ₹66,906.00 on this run against CSI 464 — the only listed wax with a bulk break (5.6% from 5 kg). But its fragrance-load ceiling isn't in our data, so it isn't a like-for-like swap until you have checked the product page and burn-tested it in the Salsa jar at your load. CSI 464 has a stated 10% maximum, which the 8% here sits inside. Choose the wax on the burn test and the client's approved sample, then compare prices — never the other way round, and never mid-run.

Buying a run this size

Every line on this list is beyond a normal cart: 70 kg of one oil against a listing that stops at 1 kg, 810 kg of wax in 10 kg bags, 5,100 jars. The listed prices are the starting point, but a run this size should go through WhatsApp: for stock confirmation, for a quote on the whole list (no volume discount figure is published), and to ask whether the oil and wax can come from single batches.

Staging deliveries is different from staging purchases. Buying the whole quantity at once — even if it arrives in two or three drops — keeps the oil and wax from the same batches and fixes your price. Buying in pieces as you go exposes you to price changes and lot changes mid-run. Buying all the wax from one batch explains why that matters, and production capacity whether you can pour 5,000 in the time you have.

The materials

If this is your first run above a few hundred candles, start smaller in the cluster: costing a 100-candle order and sizing a 500-piece inventory use the same method with fewer zeros. Wax overage for 1,000 Diwali candles breaks the wax allowance into its parts, and which materials to secure first helps sequence a run this size.
