For a lounge, charcoal is a constant cost line. To avoid overpaying or running out, calculate consumption and buy for real turnover. Step by step.
How much per bowl
On average a session uses 3–4 cubes of 25 mm plus 1–2 for reheating. At ~11–12 g per cube that’s roughly 50–70 g of charcoal per session. Large bowls and dense packs sit near the top of the range.
Monthly estimate
Simple formula:
Sessions per day × days per month × 60 g = monthly consumption.
Example: 40 sessions/day × 30 days × 60 g = 72 kg per month — about 72 packs of 1 kg. Add 10–15% buffer for peaks and waste.
How volume affects price
The bigger the batch, the lower the price per kilo. For a venue it’s cheaper to buy 1 kg packs by the case rather than piece by piece. With steady turnover it pays to lock in a regular supply — you hold the price and avoid stock-outs.
What else affects consumption
- Charcoal quality. Cheap, high-ash, short-burning charcoal is used up faster — the price saving turns into overuse.
- Heat management device. An HMD cuts consumption by 20–30%.
- Staff training. Correct lighting and service reduce waste.
Takeaway
Base consumption on session count, buy with a buffer and order by volume — that lowers the cost per bowl. Contact us — we’ll size the volume to your turnover and send IZZY COCO prices.
