Enter your guest count and desired cooked serving size to see how much raw brisket to buy.
Brisket loses a significant amount of its raw weight during a long smoke as fat renders and moisture evaporates — commonly estimated at around 45%. To get a target amount of cooked, sliced brisket per guest, you need to buy meaningfully more raw weight to account for that loss.
Source: Based on standard barbecue-catering guidance of about 1/2 pound of cooked brisket per person, with a typical 45% cooking weight loss during smoking.
Brisket typically loses around 40–50% of its raw weight during a long smoke, as rendered fat and moisture cook off over many hours — this calculator uses 45% as a middle estimate.
A common barbecue-catering estimate is about 1/2 pound of cooked, sliced brisket per person as a main course serving.
A whole packer (flat plus point) is more forgiving to cook and yields more usable meat per raw pound after trimming, though it costs more upfront than buying just the leaner flat.
