How to Calculate Buffet Quantities
Formula
Total Entree (raw) = Guests x Portion x 1.3 (shrinkage) x 1.15 (buffet buffer) / 16
Total Sides = Guests x Side Options x Portion per Side x 1.15 / 16
The Buffet Buffer
Buffets need 15-20% more food than plated service because:
Distribution Across Entrees
With 2 entree options, expect a roughly 60/40 split. With 3 options, expect 40/30/30. Prepare each entree for at least 60% of the guest count to avoid running out of the popular option.
Example Calculation
40 guests, 2 entrees at 6 oz, 4 sides at 3 oz each.
- 01Total entree raw = 40 x 6 x 1.3 / 16 x 1.15 = 22.4 lbs, round to 22 lbs
- 02Per entree option = 22 / 2 = 11 lbs each
- 03Total sides = 40 x 4 x 3 / 16 x 1.15 = 34.5 lbs, round to 35 lbs
- 04Per side dish = 40 x 3 / 16 x 1.15 = 8.6 lbs each
