03 / THE WORKING MODEL

Assumptions and limitations

Assumptions

  • Buffet baseline: 200 g main, 220 g sides, 4 appetiser pieces, 1 dessert, and 2 beverage servings per guest.
  • Plated baseline: 180 g main, 180 g sides, 3 appetiser pieces, 1 dessert, and 2 beverage servings per guest; reception baseline is 10 appetiser pieces, 1.5 desserts, and 2 beverages.
  • Beverages increase by 0.75 serving per guest for each hour after two hours, and the entered buffer applies to every category.

Check before using

  • Guest appetite varies with age, event timing, menu richness, alcohol, weather, and culture.
  • The estimate does not replace confirmed dietary requirements, allergen controls, or safe service planning.
  • Units are planning quantities, not purchasing pack recommendations.

04 / QUICK ANSWERS

Frequently asked questions

What does the buffer do?

It increases every baseline category by the entered percentage to help cover uncertainty.

Are children counted differently?

No. Enter an adult-equivalent guest count after applying your own adjustment for children or other groups.

Does this handle dietary restrictions?

No. Dietary and allergen-safe quantities must be planned separately from the overall volume estimate.
