About this calculator
Use this as a rough shopping scenario, not a serving standard. The model assigns 0.33, 0.5 or 0.66 lb of meat per meat-eating guest; estimates 1.5 buns and 2 side servings per guest; and estimates 2 beverages plus 0.75 per event hour per guest, with 0.75 lb of ice per guest. Adjust for your menu, serving sizes, weather and actual beverage choices.

Frequently asked questions
How are the food and supply amounts estimated?
The model uses fixed shopping assumptions: 0.33, 0.5 or 0.66 lb of meat per meat eater; 1.5 buns and 2 side servings per guest; 2 beverages plus 0.75 per event hour per guest; and 0.75 lb of ice per guest.
