How It Works

How Much Meat Per Person

Formula

Raw Weight = Cooked Serving / (1 - Shrinkage %)

Meat loses weight during cooking due to water and fat loss.

Typical Shrinkage

  • Lean poultry breast: 15%
  • Roasts, steaks: 25%
  • Burgers, fatty cuts: 35%
  • Ribs, bone-in: 40%
  • General Guidelines

  • Boneless: 170-225 g raw per person
  • Bone-in: 280-340 g raw per person
  • Worked Example

    Buy roast beef for 6 people, targeting 200 g cooked per person.

    people = 6cooked_serving_g = 200shrinkage_pct = 25
    1. 01Cooked serving: 200 g per person.
    2. 02Shrinkage: 25% (medium).
    3. 03Raw per person: 200 / (1 - 0.25) = 200 / 0.75 = 267 g.
    4. 04Total raw: 267 x 6 = 1600 g = 3.5 lbs.

    Frequently Asked Questions

    How much does meat shrink when cooked?

    Typically 15-40% depending on fat content, cut, and cooking method. High-heat grilling causes more shrinkage than slow roasting.

    Should I buy extra?

    Yes, buy 10-15% extra as a buffer, especially for events. Leftover meat is easy to use, but running short is difficult to fix.

    Does bone-in meat need more per person?

    Yes. Bones add weight but are not edible. Buy about 50% more raw weight per person for bone-in cuts compared to boneless.
