How it works
Buying the right amount of meat for a gathering prevents both shortages and waste, and this calculator does the math. You enter the number of guests and the serving size per person, and it returns the total meat needed in pounds, kilograms, and ounces. The calculation multiplies guests by the per-person serving, then converts the total to common units. The per-person amount is the key judgment and depends on the meal: as a main course with modest sides, plan about 8 ounces (half a pound) of cooked meat per adult; with hearty sides and appetizers, 6 ounces may suffice; for big eaters or a meat-centric barbecue, 10 to 12 ounces or more. Remember these are typically cooked-weight guidelines, and meat loses weight during cooking, so if you buy by raw weight, buy more, roughly 25 to 30 percent extra for shrinkage, and even more for bone-in cuts where the bone is not eaten. Children eat less than adults, so adjust if many guests are kids. This calculator helps hosts plan barbecues, roasts, holiday dinners, and catered events, and combined with a price per pound it helps budget. When in doubt, round up a little, since leftover meat keeps and running out is worse. For a mix of meats, split the total across them. Enter your guest count and serving size to find how much meat to buy.
Total meat = guests × ounces per person
Multiply the number of guests by the serving size per person in ounces to get the total ounces of meat, then convert to pounds (divide by 16) and kilograms. Adjust the per-person amount for whether meat is the main course and how filling the sides are.

Frequently asked questions
How much meat should I buy per person?
As a main course with modest sides, plan about 8 ounces, half a pound, of cooked meat per adult. With hearty sides, 6 ounces may be enough; for big eaters or a barbecue, 10 to 12 ounces or more. The calculator multiplies your per-person amount by the guest count to give the total to buy.
Should I account for cooking shrinkage?
Yes. Meat loses roughly 25 to 30 percent of its weight during cooking as fat and moisture render out. The per-person amounts are usually cooked-weight guidelines, so if you buy by raw weight, increase the amount accordingly. Bone-in cuts need even more raw weight since the bone adds weight but is not eaten.
How much meat for bone-in cuts?
For bone-in cuts like ribs, wings, or bone-in roasts, buy more per person because a significant portion of the weight is bone that is not eaten. A common approach is to roughly double the boneless amount, or plan around one pound of bone-in meat per person, adjusting for how meaty the specific cut is.
Do children count the same as adults?
Usually not. Children typically eat about half to two-thirds of an adult portion, so if your guest list includes many kids, reduce the total accordingly rather than counting everyone at the full adult serving. For a rough adjustment, count two children as one adult when estimating the total meat needed.
Should I buy extra meat?
A small buffer is wise. Leftover cooked meat keeps well and can be used later, while running out at an event is disruptive and hard to fix. Rounding the total up slightly, especially for barbecues and celebrations where appetites run high, ensures everyone is well fed without significant waste.
