How to calculate food cost percentage (with the simple formula)

Food cost percentage is the share of a menu item's price that goes to the ingredients used to make it. It is the fastest way to see whether a dish is pulling its weight, and it is the number lenders, landlords, and buyers look at first.

The formula

Food cost percentage = (cost of ingredients / menu price) x 100.

Two more worked examples

A taco plate: two tortillas ($0.30), a carnitas portion ($1.60), onion, cilantro, and salsa ($0.45), plus packaging ($0.15) comes to $2.50. Sold at $9.00, that is 2.50 / 9.00 = 0.278, a 27.8 percent food cost. Comfortably inside range.

A carbonara: pasta ($0.55), guanciale ($1.90), eggs and pecorino ($1.75), and pantry items ($0.30) comes to $4.50. Sold at $17.00, that is 4.50 / 17.00 = 0.265, a 26.5 percent food cost. The same dish at $13.00 would run 34.6 percent, which is why the price point matters as much as the recipe.

Working backwards: from target to menu price

The same formula sets prices. Divide the dish cost by your target food cost percentage as a decimal: a $4.00 dish at a 30 percent target is 4.00 / 0.30 = $13.33, then round to a clean menu number like $13.50.

What is a good food cost percentage?

Most full-service restaurants aim for 28 to 35 percent. Bars and cafes with high-margin drinks often run lower. The right target depends on your concept, your labor model, and your rent, so treat these as a starting range, not a rule.

How to actually track it

1. 1Build a recipe for each dish with exact quantities, including packaging and add-ons.
2. 2Price every ingredient from your real vendor invoices, not last year's guess.
3. 3Divide ingredient cost by menu price for each dish.
4. 4Re-check whenever a vendor price changes, because a 12 percent produce hike can quietly push a dish over target.

The hard part is not the math, it is keeping ingredient prices current. That is exactly what Smooth Ops automates: upload an invoice and every dish that uses those items re-costs itself.
