What Is Food Cost and How to Reduce It Without Cutting Quality

The food cost formula

Food cost is the percentage of your selling price that goes into raw ingredients. The formula: food cost % = (ingredient cost / selling price before tax) × 100. The crucial detail is 'before tax': VAT or sales tax is not your revenue — you collect it for the tax office, so it must stay out of any margin calculation.

Example: a dish costs 4.20 € in ingredients and sells at 16.50 € including 10% VAT. The price before tax is 16.50 / 1.10 = 15.00 €, so the food cost is 4.20 / 15.00 × 100 = 28%. Calculated on the tax-inclusive price it would look like 25.5% — a 2.5-point illusion.

You can measure it dish by dish (theoretical food cost, from your recipe costings) or for the whole business: food purchases for the period, adjusted by the change in inventory, divided by food sales before tax. Comparing theoretical against actual tells you how much money escapes between the spec sheet and the reality of the kitchen.

Healthy ranges by type of restaurant

There is no universally 'correct' food cost: it depends on your business model, average ticket and labour structure. As a general industry reference, most healthy restaurants sit between 25% and 35%. Roughly:

• Fast food and fast casual: 25-30%. High volume, highly standardised portions.
• Fixed-price lunch menus: 30-35%. Tight margin compensated by turnover.
• Mid-range casual dining: 28-32%. The most common band.
• Fine dining: 32-38%, sometimes more. The product is the star and the ticket supports it.
• Bars and cafés: 20-28% blended, because drinks carry far higher margins than food.

The trend matters more than the number

More telling than the absolute value is its direction: a stable 30% is better news than a 27% that has been creeping up for three months for reasons nobody can name. Small, sustained drifts destroy the most margin precisely because they never hurt enough to trigger an investigation.

Watch the gap between theoretical food cost (what your costings say) and actual food cost (what your purchases say). A 1-2 point difference is normal operational waste; beyond 3 points there is a specific leak to hunt down.

The 5 typical leaks that inflate your food cost

When actual food cost persistently runs above theoretical, the money is escaping through one of these five routes:

• Unmeasured waste: trim loss, expired stock and over-production that ends up in the bin without being recorded anywhere.
• Inconsistent portions: without scales and spec sheets, every cook plates by eye and the deviation can reach 10-20% per serving.
• Theft and internal waste: uncontrolled staff meals, unrecorded comps and product walking out the back door.
• Outdated supplier prices: you cost dishes with months-old prices while the supplier has quietly raised 8-15%, line by line.
• An unbalanced menu: the floor team pushes dishes that sell well but earn little, while your most profitable items sit buried in the menu.

How to reduce it without cutting quality

Lowering food cost does not mean buying worse product. The most effective levers are exactly the ones guests never notice:

• Standardise portions with spec sheets and a scale: the best effort-to-result ratio on this whole list.
• Benchmark and renegotiate suppliers 2-3 times a year: in commodity categories (oil, dairy, dry goods) prices for the same product vary 10-20% between suppliers.
• Use the whole product: fish bones become stock, trimmings become croquettes, yesterday's bread becomes dessert.
• Adjust portion size before ingredient quality: going from 200 g to 180 g of protein cuts the cost 10% and almost nobody notices; a cheaper ingredient is noticed immediately.
• Rebalance the menu: give your highest-margin dishes the best position, the best description and the server's recommendation.

Monitor food cost every week

Cost control in a restaurant does not work as a yearly audit — it works as a weekly habit. A 30-minute routine every Monday is enough to catch deviations while they are still cheap to fix.

The minimum routine: log the week's purchase invoices and update any price that changed; check that the costings of your 10 best-selling dishes still reflect current prices; calculate the weekly global food cost (purchases ± inventory change, over sales before tax); and compare theoretical against actual.

A single missed price increase does real damage: if olive oil goes from 4.50 to 6.00 €/l and you use it in 40 dishes, that is hundreds of euros a month evaporating before the monthly close ever tells you. Weekly frequency exists to catch exactly that.

Frequently asked questions

What is a good food cost percentage for a restaurant?

As a general reference, between 25% and 35% of the selling price before tax, depending on the business model: fast food sits at the low end and fine dining at the high end. More important than the number itself is that it stays stable and that you can explain every deviation.

Is food cost calculated with or without VAT?

Always without VAT. Tax is money you collect for the government, not revenue. Divide the menu price by 1.10 (at 10% VAT) to get the real selling price before computing the percentage — otherwise you credit yourself 2-3 points of margin that do not exist.

What is the difference between theoretical and actual food cost?

Theoretical comes from your recipe costings: what the dishes sold should have cost. Actual comes from purchases adjusted by inventory: what you really spent. A 1-2 point gap is normal; above 3 points there is a leak — waste, portions, theft or stale prices — to track down.
