Food Cost Calculator: How to Track Cost in Your Restaurant

A food cost calculator does one job brilliantly: it tells you exactly how much each dish costs to make, so you can price it for profit instead of hoping.

The core calculation

For any dish:

Food cost % = (total ingredient cost ÷ selling price) × 100

If a pasta dish costs 28 in ingredients and sells for 95, that's a 29% food cost — healthy. The trouble starts when you have 80 dishes and prices keep moving.

What a good calculator tracks

• Per-ingredient cost in the unit you buy (per kg, per litre, per piece).
• Recipe quantities for each dish, so cost rolls up automatically.
• Portion and packaging costs, which owners often forget.
• Live updates — when one ingredient's price rises, every dish that uses it should re-cost instantly.

Why spreadsheets break down

A spreadsheet is fine for ten items. Past that, one supplier price change means editing dozens of formulas by hand — so most owners simply stop updating, and their "food cost" slowly drifts away from reality. That gap is where profit leaks.

The smarter way

Wizzora is a food cost calculator built for real kitchens: store each recipe once, and when an ingredient price changes you update it in one place — every affected dish re-costs automatically and flags anything that crept above your target margin.
