How does this calculator work?
For G adults and K children over H hours: buy (G × 0.5 + K × 0.25) lb raw meat, G × 2 + K × 1 burgers and the same in sausages, G × H drinks, 1.5 lb ice per person, and one condiment bottle per six guests. Multiply by 1.3 for a hearty crowd. Always buy 10–15 % extra for seconds.
Formula
How this is calculated
The standard catering rule for BBQ events is about 0.5 lb (225 g) of raw meat per adult and 0.25 lb (115 g) per child. Raw meat loses roughly 25–30 % of its weight during cooking, so 0.5 lb raw yields around 0.35 lb cooked — a satisfying single serving. For a hearty crowd (hungry workers, sports teams) increase to 0.65–0.75 lb per adult; for lighter casual events, 0.35–0.4 lb is usually enough.
Burgers and sausages are estimated at two per adult and one per child, which matches typical consumption when both are available alongside sides and salads. Sides (coleslaw, potato salad, corn, bread rolls) add about 0.5 lb per person. Ice is estimated at 1.5 lb per person — enough to fill coolers for drinks over a 4-hour event, with some margin for a warm day.
Drinks follow the rule of one serving per guest per hour, which balances those who drink little with those who drink more. Condiment bottles are budgeted at one per six guests (ketchup, mustard, relish). All quantities scale by the appetite multiplier, so a "hearty" crowd gets 30 % more of everything. These are planning estimates — real consumption varies with weather, time of day and crowd preferences.
Frequently asked questions
Plan for about 0.5 lb (225 g) of raw meat per adult — burgers plus any sausages or steaks combined. Children typically eat about half that. Raw meat shrinks by 25–30 % during cooking, so 0.5 lb raw delivers roughly a third-pound serving cooked. Increase to 0.65–0.75 lb per adult for a particularly hungry crowd.
Two burgers per adult is the standard estimate for a BBQ where burgers are the main protein alongside sausages and hot dogs. If burgers are the only meat, increase to three per adult. For children, one burger each is usually sufficient. Always have a few extras in case some people want seconds.
A good rule is 1–2 lb of ice per person for a 4-hour event. Use 1 lb per person in mild weather, 1.5–2 lb on a hot day or if the cooler will be opened frequently. Ice blocks last longer than cubed ice; for a 50-person party, plan 75–100 lb of ice across your coolers.
