Step-by-Step Examples
Example 1
50-Person Buffet
50 guests, 4 hours, full buffet.
- Protein: 50 x 0.4 = 20 lbs
- Sides: 50 x 0.3 = 15 lbs per side
- Drinks: 50 x 4 x 0.75 = 150 units
✓ 20 lbs protein / 15 lbs per side
Example 2
Wedding Dinner 100
100 guests, formal dinner.
- Protein: 100 x 0.38 = 38 lbs
- Sides: 100 x 0.25 = 25 lbs each
✓ 38 lbs protein
Example 3
BBQ 30 People
30 guests, BBQ.
- Protein: 30 x 0.5 = 15 lbs raw meat
- 15 lbs raw → ~10-11 lbs cooked
✓ 15 lbs raw meat

Common Mistakes to Avoid
⚠️
Forgetting cooking loss
Raw meat loses 25-40% when cooked. For 10 lbs of cooked protein, buy 13-15 lbs raw.
⚠️
Not buffering
Always add 10-15% to every estimate. Running out of food at a party is far worse than having leftovers.
