What this calculation means
An item food-cost percentage expresses a menu item’s ingredient cost as a share of its selling price. It compares one serving or item with the matching sale.
Packaging, labor, and overhead are outside the ingredient numerator unless a separately labelled direct-cost task is used.
How to use this calculator
Enter the ingredient cost and selling price for the same item. Use a selling-price basis that excludes sales tax, tips, and fees.
Formula and variables
Item food-cost percentage = Food cost ÷ Selling price × 100
- Food costUSD
- Ingredient cost for the stated serving or item.
- Selling priceUSD
- Price charged for the same serving or item.
The percentage display uses one decimal place. Intermediate ratios retain their precision before the displayed result is rounded.
Understand your result
The result is the ingredient share of that item’s price. It does not describe inventory-based food use over a period.
Worked example
Food cost is $4.50 and selling price is $15.
Food cost: 4.5 USD
Selling price: 15 USD
- Divide $4.50 ingredient cost by a $15 tax-exclusive price = 0.30.
- Multiply by 100 = 30.0% item food cost.
Example result: 30.0%
Frequently asked questions
Is a 30% result also a 70% net profit margin?
No. The remainder has not paid for packaging, labor, rent, or other operating costs. This ratio measures the stated ingredient scope only.
Can I compare it with the period inventory ratio?
Only after naming the difference. A menu item ratio and a period food-used ratio have different numerators and represent different decisions.
