BBQ Calculator
Calculate the ideal amount of meat, drinks and sides for your barbecue.
About this tool
The BBQ Calculator automatically estimates the quantity of each item needed for a Brazilian barbecue based on the number of adult and child guests. It covers beef, sausage (linguiça), chicken, garlic bread, charcoal, soda, water, ice, and optionally beer — with quantities adjusted for standard or long-duration events.
To use it, enter how many adults and children will attend, choose whether the barbecue will run long (more than 5 hours), and check whether to include beer in the estimate. The tool recalculates everything instantly and shows each item with the recommended weight or volume. Estimates for children use half the adult consumption, and the long-duration option applies a 1.5× factor across all quantities.
Organizing a barbecue without a reference like this is a challenge: buying too little disappoints guests, while buying too much leads to waste and unnecessary cost. The calculator serves as a starting point for shopping, whether for a Sunday family cookout, a company team event, a birthday party, or a larger gathering.

Are the quantities exact or estimates?
They are estimates based on average consumption patterns. Actual appetite varies greatly by group and context — use these as shopping guidelines, not exact measures.
Why is there a 'long barbecue' option?
Barbecues lasting more than 5 hours tend to have higher meat and drink consumption. The option applies a 1.5× factor across all quantities to reflect that pattern.
