About this calculator
The Barbecue Calculator helps you plan the ideal amount of meat, charcoal, and sides for your event. It considers the number of adults and children, applying average consumption per person: 400 grams of meat for adults and 200 grams for children. Charcoal is calculated based on total meat weight, multiplied by 1.5 to ensure enough coals. Additionally, the tool suggests portions for sides like farofa, vinaigrette, and garlic bread, adjustable to your guests' profile. It's perfect for avoiding waste or shortage at parties, gatherings, and family reunions.
To use it, simply enter the number of adults and children. The calculator processes the data and displays recommended quantities in kilos or liters. Keep in mind that appetite may vary depending on the event type (lunch or dinner) and the presence of other dishes. The tool also allows customizing sides, drinks, and desserts based on market averages. Remember that factors like weather and barbecue duration influence consumption. Use the values as a guide and adjust according to your experience.
Common use cases include weekend barbecues, birthdays, and holidays. For example, for 10 adults and 5 children, the calculator suggests 5 kg of meat (4 kg for adults + 1 kg for children) and 7.5 kg of charcoal. Sides like 2 kg of farofa and 3 liters of soda are estimated. Be careful not to overestimate: if there are many snack options, reduce the meat. Also consider bone-in cuts, which yield less. The tool is a practical starting point, but the host's common sense is essential.
Frequently asked questions
How does the calculator determine the amount of meat per person?
It uses averages: 400 g for adults and 200 g for children. This considers common cuts like picanha, chicken, and sausage.
Do I need to buy exactly the calculated charcoal?
The calculation is an estimate. Buy a little extra to be safe, as factors like wind and grill type affect consumption.
Does the calculator include drinks?
Yes, it suggests amounts of soda, beer, and water based on guest count, but you can adjust manually.
What if there are many appetizers before the barbecue?
Reduce the meat by about 20% if there is a heavy starter. The calculator only considers the main course.
Does the calculator work for any type of meat?
Yes, but remember that bone-in cuts (like ribs) yield less. Adjust the quantity if you use mostly those cuts.
