This calculator tells you exactly how much raw meat, sides, buns, and drinks to buy for any backyard cookout. Here is how to get an accurate shopping list:
- Enter your guest count. Separate adults and kids. Children under 12 are counted at half a portion, which reflects typical real-world eating habits at cookouts.
- Set your party length. Drink quantities scale with time: guests consume 2 drinks in the first hour and 1 per hour after that. A 3-hour party for 10 adults means 40 drinks total.
- Read your shopping list. The calculator gives raw meat weight (accounting for the 30% shrinkage from cooking), sides in pounds, bun count, drink count, and ice. All values round up so you do not run short.
The meat estimate uses 0.7 lbs of raw meat per adult equivalent, which yields approximately 0.5 lbs of cooked meat per person, a generous serving for a main course. Use the Share button to send your shopping list to a co-host.
About the BBQ Party Calculator
The standard rule for BBQ planning is half a pound of cooked meat per adult. Because raw meat loses about 30% of its weight during cooking (from moisture and fat rendering), you need to purchase roughly 0.7 lbs of raw meat per adult. Children eat about half that amount. Side dishes like potato salad, coleslaw, and beans typically weigh about a third of a pound per person in total.
The drink formula accounts for the common pattern where guests are thirstiest in the first hour of a cookout, then settle into a slower pace. Ice estimates assume approximately 1 lb of ice per drink, which keeps a well-insulated cooler cold throughout the event. All calculations run in your browser with no data stored or transmitted.
Frequently Asked Questions
How much meat do I need for a BBQ for 20 people?
For 20 adults, plan to buy about 14 lbs of raw meat. This accounts for the 30% shrinkage from cooking and yields roughly half a pound of cooked meat per person. If you are serving ribs, which have more bone weight, increase the raw purchase to about 1 lb per person. For a mix of adults and kids, enter the exact counts into the calculator for a precise number.
Why does raw meat shrink so much when grilled?
Meat is primarily water. When heat is applied, moisture evaporates and fat renders out, which reduces the total weight by 25-35%. Leaner cuts like chicken breast shrink less (around 20-25%), while fattier cuts like pork shoulder or brisket can shrink 30-40% or more. The calculator uses a 30% average, which works well for a mixed grill. If you are cooking mostly lean poultry, you can reduce the estimate slightly.
How many drinks should I plan per person for a backyard BBQ?
A good rule is 2 drinks per person for the first hour and 1 drink per person for each additional hour. For a 3-hour cookout with 10 adults, that is 40 drinks. This formula works for any mix of beer, soda, and water. If the weather is hot or your guests are active, add 10-20% more. Always have extra water on hand, especially in summer.
What sides should I plan for a BBQ party?
Classic BBQ sides include potato salad, coleslaw, baked beans, corn on the cob, and pasta salad. Plan about a third of a pound of side dishes per person in total. For 20 guests, that is roughly 7 lbs of prepared sides. A standard deli container of potato salad or coleslaw holds about 3 lbs, so you would need 2-3 containers for 20 people. Corn on the cob is a separate count: plan 1-2 ears per person.
