Formula and methodology
Formula: Base food = adults × adult serving + children × adult serving × child fraction; planned food = base × (1+waste rate).
The estimate exposes portion and planning assumptions instead of presenting one universal serving rule.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Adult guests — minimum 0; maximum 100000
- Child guests — minimum 0; maximum 100000
- Adult serving — kg; minimum 1.0E-6; maximum 100
- Child serving as adult fraction — %; minimum 0; maximum 1000
- Planning allowance — %; minimum 0; maximum 1000
Worked example
| Input | Value |
|---|---|
| Adult guests | 10 |
| Child guests | 4 |
| Adult serving | 0.3 |
| Child serving as adult fraction | 60 |
| Planning allowance | 10 |
Base food = 3.72 kg; planned food ≈ 4.092 kg.
Assumptions and limits
- Guests are whole people and portion weights use kilograms.
- Child fraction and allowance are planning inputs, not dietary or catering standards.
- Menu composition, appetite, leftovers, allergies, storage, and food safety are not modeled.
