About Catering Calculator

Calculate catering quantities, portions, and costs for events. Part of the DevTools Surf developer suite. Browse more tools in the Event Planning collection.

Use Cases

• Estimate food quantities and costs for a corporate event or wedding
• Calculate per-head catering costs for budget approval
• Plan portion sizes across multiple dietary categories (vegan, gluten-free)
• Generate a catering brief for RFP submission to catering vendors

Tips

• Enter guest count with a 10% buffer for unexpected attendees — catering quantities that run out cannot be recovered mid-event
• Use the meal-type selector (buffet, plated, cocktail) — quantity estimates differ significantly: buffet requires 1.5-2x more food than plated service
• The cost breakdown separates food, staffing, equipment rental, and gratuity — export it as a PDF for vendor quote comparison

Fun Facts

• The modern catering industry traces to 19th-century England, where firms like Ring & Brymer provided food services for state banquets and royal events. The term 'caterer' appears in English texts from the 14th century as a person who 'bought provisions.'
• The rule of thumb for cocktail party food is 12-15 bite-sized pieces per person per hour. For a 3-hour party, that is 36-45 pieces — a quantity consistently underestimated by first-time event planners.
• Food waste at large events averages 30-40% of prepared portions, according to waste audits by organizations like WRAP (UK). Precision catering calculators emerged partly in response to sustainability pressure from event clients.

FAQ

How much food should I plan per person?

Buffet dinner: 6-8 oz protein, 4-6 oz starch, 3-4 oz vegetables per person. Plated dinner: smaller portions, typically 4-6 oz protein. Cocktail reception (no dinner): 12-15 bites/person/hour. Always add 10-15% overage.

What is the difference between catering and food service?

Catering typically implies a contracted, full-service provider handling planning, preparation, delivery, and service for a specific event. Food service is the broader category including restaurants, cafeterias, and institutional feeding.

Should I tip catering staff?

Gratuity is sometimes included in catering contracts (check the fine print). If not, 15-20% of the food and labor total is standard. Pass-through costs (equipment rental, venue fees) are not typically tipped.
