Every BBQ buying disaster starts the same way: someone reads "half a pound of meat per person," buys exactly that in raw brisket, and serves a crowd of twenty about eleven portions. The missing concept is yield — the gap between what you buy and what comes off the smoker. For some cuts that gap is nearly half the weight.
The serving baseline
Caterers plan ½ lb (225 g) of cooked meat per adult as the main, with kids under ~12 counted as half portions. Meat-focused crowds run 25% higher; a table crowded with sides runs 20% lower. Those are the toggles in the BBQ calculator.
The yield table — what you actually buy
| Cut | Yield (cooked ÷ raw) | Raw to buy per adult | Where the weight goes |
|---|---|---|---|
| Brisket (whole packer) | 50–55% | ~1 lb / 450 g | fat trim, rendered fat, moisture |
| Pork shoulder (pulled) | ~60% | ~0.75 lb / 340 g | bone, fat, moisture |
| Pork ribs | — | half rack (6–7 ribs) | portioned by rack, not weight |
| Chicken, bone-in | ~65% | ~0.75 lb / 340 g | bones, rendering |
| Chicken, boneless | ~75% | ~0.6 lb / 270 g | cooking loss only |
| Steak (individual) | ~85% | ~0.7 lb / 320 g | trim, cooking loss |
| Burgers | — | 1.5 × ¼-lb patties | counted, not weighed |
| Hot dogs / sausages | — | 1.5 each | counted |
Worked example: BBQ for 20 adults and 8 kids
Effective eaters: 20 + (8 × 0.5) = 24. Serving pulled pork as the single main: 24 × 0.45 lb cooked = 10.8 lb cooked → at 60% yield, buy an 18 lb bone-in shoulder (or two 9-pounders, which cook faster and give more bark). Add buns at 1.5 per eater plus 20% spare = 44 buns, and 4 oz of each side per guest.
Serving two meats
The instinct is to halve each. In practice people take some of both and eat about 20% more total, so run each meat at 60% of your headcount. Brisket + chicken for 20 adults = brisket for 12, chicken for 12.
Three mistakes that survive every summer
- Buying brisket by cooked-weight math. The most expensive way to under-feed people. If the raw number feels alarmingly large, it's probably right.
- No hold plan. Brisket and shoulder finish when they finish — build in a 2-hour buffer; wrapped in towels in a dry cooler they hold beautifully for 4+.
- Forgetting the drinks scale with the smoke time. A 6-hour backyard smoke session is a 6-hour party. The drink calculator and ice calculator use hours for exactly this reason.
