About this tool
What the Menu Allergen Coverage Calculator does
Guests with food allergies need enough safe choices. Counting how many dishes contain each major allergen shows the share of the menu that is suitable for each allergy and highlights gaps. The defaults list the nine major food allergens recognised in the US.
It also works as a allergen tracking calculator.
Formula
- Safe dishes = dishes on the menu − dishes containing the allergen
- Share safe = safe dishes ÷ dishes on the menu
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Dishes on the menu | 40 |
| Dishes containing each allergen | 9 entries |
| Minimum safe options you want | 10 |
| Result | Value |
|---|---|
| Allergen with fewest safe options | Wheat |
| Safe options for it | 20 |
| Allergens below your minimum | 0 |
How to read the result
“Free from” on the menu also requires controlling cross-contact in the kitchen: separate equipment, prep areas and procedures.
Labelling rules differ by country; the UK and EU recognise 14 allergens, for example, so adjust the list for your location.
