BBQ & Party Planner Calculator

BBQ food quantity planning uses per-person serving estimates to calculate total food needed for a group, then scales by expected appetite levels and number of sides.

Main Protein Formula:

Raw meat to buy = Guests × raw serving per person

The serving sizes below are already raw weights, which is what you hand over at the counter, so nothing else needs multiplying in. Where shrinkage matters is on the other side of the cook: it tells you how much actually reaches the plate.

Cooked yield = raw weight × (1 − shrinkage)

Typical losses, which come from rendered fat, evaporated moisture, and bone:

• Ground beef, sausages: 20–25% loss, so 10 lbs raw serves about 7.5 to 8 lbs
• Chicken, bone-in: 30–35% loss
• Bone-in ribs: 35–40% loss
• Pork shoulder: 35–40% loss, so a 10 lb butt gives roughly 6 to 6.5 lbs of pulled pork
• Brisket: 40–50% loss, the heaviest of the lot because so much fat is trimmed or renders out

Brisket catches people out every time. Buy it by the cooked weight you want to serve and you end up close to half short.

Recommended serving sizes, raw weight per person:

Worked example, 20 guests at a full BBQ: The full-dinner setting plans 8 oz of raw meat a head, matching the large-appetite column. 20 × 8 oz = 160 oz = 10 lbs raw. If that is all burgers, expect about 7.8 lbs on the plate once they are cooked. If it is brisket, expect nearer 5.5 lbs, which is why a brisket party has to start from a bigger raw number in the first place.

Side dishes per person:

• Coleslaw: 4 oz (1/2 cup)
• Potato salad: 5 oz
• Corn on the cob: 1 ear
• Baked beans: 4 oz

Practical tip: Prepare 10–15% more than the numbers say. BBQ guests consistently outeat their own average, especially when the food is laid out and the afternoon is long. Leftover brisket is a good problem; running out at 4pm with half the guests still hungry is not.
