An event food calculator determines how many pounds of protein, sides, appetizers, and desserts to buy for DIY catering. It accounts for cooking shrinkage — the 25-40% weight lost during roasting, smoking, or grilling — so you buy enough raw weight to serve the correct cooked portions.
Calculate exactly how much raw meat to buy for your event. We account for cooking shrinkage (yield loss) so you don't end up short on food. All calculations happen instantly in your browser. Your data never leaves your device.

Catering Efficiency Gear
When cooking for 50+ people, guessing when the meat is done will ruin the event. You absolutely must use a multi-probe wireless meat thermometer to monitor internal temperatures without constantly opening the smoker or oven. For serving, keep your carefully calculated portions at safe temperatures (above 140°F) for hours by investing in stainless steel chafing dish setsthey look professional and prevent foodborne illness.
How to Calculate Meat Portions for a Party
The biggest mistake DIY caterers make is forgetting about cooking shrinkage (yield loss). A standard dinner portion requires about 7 ounces of cooked meat per adult. However, if you buy 7 ounces of raw brisket per person, you will run out of food. Brisket loses about 50% of its weight during trimming and the long smoking process. Pork shoulder loses about 55%, and bone-in ribs lose a massive 60% due to bone weight. CaterMath works backward from the required cooked portions to tell you exactly how many pounds of raw meat you need to buy at the grocery store, eliminating the stress of under-catering your wedding or backyard BBQ.
Frequently Asked Questions
How many pounds of meat per person for a BBQ?
Plan for 1/3 to 1/2 pound of cooked meat per adult when protein is the main course with sides. However, you must buy more raw weight because meat shrinks during cooking: brisket loses 40%, pulled pork loses 40%, ribs lose 30%, and chicken loses 25%. For 50 guests wanting brisket, buy at least 42 pounds raw.
How much food do you need per person for a buffet?
A full dinner buffet needs approximately 1.5 pounds of total food per person: 6-8 oz protein, 4-6 oz starch/grain, 3-4 oz vegetables, 2-3 oz salad, and 2-3 oz dessert. For appetizer-only events, plan 8-12 pieces per person over 2-3 hours. Increase quantities by 15% if there are no other food options.
What is cooking shrinkage and why does it matter for catering?
Cooking shrinkage is the weight lost to moisture evaporation and fat rendering during cooking. A 10-pound beef brisket yields only about 6 pounds of sliceable meat after smoking. Ignoring shrinkage is the #1 reason DIY caterers run out of protein. Always calculate raw purchase weight from desired cooked serving weight.
