How to Plan Catering Quantities

Formula

Portions = Guests × Portions/Guest;
Cost = (Food + Beverage) × Guests

Buffet events need 15-20% more food than plated events since guests serve themselves and take larger portions. Cocktail receptions use lighter fare.

Plan 2-3 beverages per guest for a 2-hour event and add 1 drink per additional hour. Offer both alcoholic and non-alcoholic options.

Common use cases:

  • Wedding reception planning
  • Corporate event catering
  • Party food budgeting
