Charcoal cost per hour, not per bag: what a restaurant really pays for fuel

Charcoal is bought by the pound and burned by the hour. Comparing price per bag tells you very little about what a station costs to run. Here is how to compare fuels the way your P&L sees them.

The number that matters: cost per service

Your fuel cost for one service is simple:

pounds burned per service × price per pound

A cheap fuel that burns out fast can cost more per service than an expensive one that lasts. The price per pound is only half the formula.

How to compare CHARBLOX with lump

One pound of CHARBLOX does the work of about 3–5 pounds of average charcoal: 3–4× for Classic Hardwood and 4–5× for Dragon Fire Bamboo. Our load planner uses 3.5 for hardwood and 4.5 for bamboo.

So the fair comparison is not CHARBLOX's price per pound against lump's. It is CHARBLOX's price per pound divided by that ratio, against lump's price per pound:

CHARBLOX price per lb ÷ 3.5 (hardwood) or 4.5 (bamboo)
vs.
your lump price per lb

A worked example using our own retail price: the 10 lb Classic Hardwood bag is $33.99, about $3.40 a pound. Divided by 3.5, that is about $0.97 for each pound of lump it replaces. Typical US lump sells for $1–3 a pound. Trade and case pricing for kitchens is lower than retail.

These ratios are starting points. Your real numbers depend on the station, airflow and how tightly you choke the fire at close. Weigh what you burn for a week on each fuel and use your own figures.

The costs that are not on the invoice

Dust and small pieces. Lump is sold by weight, and every bag includes fines and chips that burn off before the grill is useful. You pay for them anyway. CHARBLOX logs are uniform, so the whole bag is fuel.
Reloading. Every top-up is a cook's time and a dip in temperature mid-service. A load that lasts through service means fewer interruptions.
Ash. Low-ash fuel means less to clean out of the box and less to haul at close.
Leftovers. Dense logs can be choked at close and relit next service. What is left over is the first part of tomorrow's load, so count it as fuel you did not have to buy. See how to reuse charcoal.
Consistency. When every log is the same size and density, every cook builds the same fire. That makes training easier and your fuel spend predictable.

Run your own numbers

Write down how many pounds of charcoal the station burns in a typical service.
Put that into the load planner on our home page. It estimates the CHARBLOX load per service, the pounds saved per week, and the weekly order in bags.
Multiply each fuel's pounds per service by its price per pound.
