Buffet Cost Calculator
Calculate buffet food quantities and costs, incorporating entree choices, side stations, chafing equipment rentals, and a 12% over-catering buffer.
Buffet Sizing & Preparation Formula
Prepared Portions = Guests × (1 + Safety Buffer %); Buffet Total = (Guests × Price/Person) + Chafing Rentals; Servers = Ceil(Guests / 30)- Safety Buffer: Self-service buffets require 10%–15% extra food to ensure chafing pans never run empty for late table calls.
- Entree Complexity: Adding a 2nd or 3rd protein increases ingredient waste and station setup fees ($5–$8/person).
- Staffing Ratio: 1 attendant per 30 guests to replenish chafers and clear plates.

Frequently Asked Questions
Why do buffets require more food than plated dinners?
Plated dinners have exact portion control (e.g. exactly 6 oz chicken per plate). On buffets, early guests often take 1.3 to 1.5 portions, requiring a 10% to 15% over-catering buffer so the final tables still have full selections.
