Universal Food Portion Calculator
Professional catering tool for calculating precise portions of ANY food product with yield percentages, AP/EP conversions, buffet scaling, and multi-currency cost estimation.
What Is This Universal Food Portion Calculator?
This is a professional-grade catering calculator designed to work with any food product you’re planning to serve. Whether you’re catering a wedding, planning a family dinner, meal prepping for the week, or running a commercial kitchen, this tool provides precise calculations based on industry-standard professional catering mathematics.
How This Universal Tool Works:
Unlike basic portion calculators that only give you generic “servings,” this advanced tool accounts for the real-world complexities of food preparation:
- Yield Percentages: Meat shrinks when cooked (typically 25% loss), vegetables lose weight when trimmed and cooked (10-45% loss), and grains expand dramatically (150-500% increase).
- AP vs EP Calculations: “As Purchased” (AP) weight includes bones, peels, shells, and inedible parts. “Edible Portion” (EP) is what guests actually eat.
- Service Style Adjustments: Plated meals = 100% standard portions. Buffet style = 85% portions. Cocktail hour = 60% portions.
- Appetite Weighting: Adjust portions from 70% (children, seniors) to 150% (athletes, heavy eaters).
- Dietary Substitutions: If 20% of guests are vegetarian, meat portions are automatically reduced.
- Smart Grocery Rounding: Converts precise amounts into practical shopping quantities.
- Safety Margin Buffer: Adds 0-30% buffer (standard 10%).
- Multi-Currency Cost Estimation: USD, GBP, or EUR.
Why This Tool Is Truly Universal:
Includes 54 pre-programmed foods across 6 categories with accurate professional yield data. The methodology can be applied to any food product.
