Key Takeaway
UK restaurant food cost target: 28–32% of net (ex-VAT) revenue. Always calculate against net revenue — using gross (VAT-inclusive) revenue understates your food cost% by approximately 17% and gives you false confidence. If you’re running above 35%, you’re losing more than £35 from every £100 of food revenue to ingredient cost before a single wage, utility or rent payment.

Food cost percentage tells you what share of every pound of food revenue was spent on ingredients. The UK industry target for casual dining and food pubs is 28–32%. At 32%, you retain 68p of every £1 as gross profit to cover labour, rent and overheads. At 40%, you retain only 60p — and most independent restaurant cost structures make that gap impossible to recover.
What Is the Food Cost Percentage Formula?
Food Cost % = (Cost of Ingredients Sold ÷ Net Food Revenue) × 100
Cost of Ingredients Sold = Opening Stock + Purchases during the period − Closing Stock. This is not your invoice total for the week. It is what was actually consumed in production. If you over-order and waste 15% of your stock, that waste is captured here — your food cost% reflects real usage, not just what you bought.
Worked example: Opening stock £4,100 + weekly purchases £6,900 − closing stock £4,400 = Cost of ingredients sold: £6,600. Net food revenue for the week: £21,000. Food cost% = £6,600 ÷ £21,000 × 100 = 31.4% — within target.
The VAT Trap: Why Most Operators Overstate Their Position
This is the most common food cost calculation error I see. Many operators run their food cost% against the till total — the gross receipt including 20% VAT. This inflates the denominator and makes food cost% appear lower than it actually is.
Example: Your till shows £25,200 food revenue. Your actual net revenue (ex-VAT) is £21,000. If your food cost is £6,600:
Wrong (gross including VAT): £6,600 ÷ £25,200 × 100 = 26.2% — looks well under target.
Right (net excluding VAT): £6,600 ÷ £21,000 × 100 = 31.4% — still within benchmark, but the picture is very different.
The same VAT trap applies to your weekly P&L and your GP% calculation. Always strip VAT before running any operational percentage.
UK Food Cost Benchmarks by Operation Type
| Operation Type | Food Cost % Target | GP % Target | Red Flag |
|---|---|---|---|
| Fast casual / QSR | 25–30% | 70–75% | >33% |
| Casual dining | 28–32% | 68–72% | >35% |
| Food pub | 28–32% | 68–72% | >35% |
| Fine dining | 30–35% | 65–70% | >38% |
Fine dining runs higher food cost because premium ingredients — aged beef, hand-picked seafood, specialist cheeses — carry a higher purchase cost. The model compensates through significantly higher revenue per cover (£60–120+) rather than volume.
What Pushes Food Cost Above Target?
Over-ordering and wastage. This is the single biggest driver. Ordering based on habit rather than forecast covers means you carry stock that expires before it sells. A weekly stock check against par levels — taking 20–30 minutes every Sunday morning — typically cuts food cost by 2–4 percentage points within a month at most operations.
Portion control inconsistency. Spec every dish with weights. A chicken breast portion specced at 180g that your kitchen serves at 220g costs you 22% more per plate than your pricing model assumes. Over 200 portions a week, that’s the equivalent of giving away 40 portions free. Weighed portioning with a kitchen spec sheet is non-negotiable at scale.
Supplier price increases not passed to the menu. UK food inflation has been significant. If your chicken breast cost £3.20/kg 18 months ago and is now £4.10/kg, and your menu price hasn’t moved, your food cost% on every chicken dish has drifted upward by 5–8 percentage points. Quarterly menu price reviews against actual cost data are essential.
Staff meals not tracked separately. Staff meals are a legitimate cost — but they should be tracked as a separate line item, not absorbed into your kitchen food cost. Untracked staff meals inflate food cost% and give you an inaccurate picture of your kitchen’s actual performance.
Theft. Industry research consistently shows that stock theft affects approximately 60% of hospitality businesses, typically costing 2–5% of food revenue annually. This is an uncomfortable truth but a real operational cost. Restricted store access, daily stock counts for high-value items (spirits, premium cuts), and regular spot-checks are the most effective controls. If your food cost% is consistently 3–4% above target with no obvious explanation, theft is worth investigating.

Frequently Asked Questions
What is a good food cost percentage for a UK restaurant?
28–32% of net (ex-VAT) food revenue for casual dining and food pubs. Fast casual and QSR operations target 25–30%. Fine dining may run 30–35% due to premium ingredient requirements. Above 35% in any format is a red flag requiring immediate investigation.
How do I calculate restaurant food cost percentage?
Food Cost % = (Opening Stock + Purchases − Closing Stock) ÷ Net Food Revenue × 100. Always use net (ex-VAT) revenue. Using gross revenue including VAT understates your food cost% by approximately 17% and creates a false picture of performance.
Does theft really affect food cost in restaurants?
Yes. Industry data suggests theft affects approximately 60% of hospitality businesses, typically costing 2–5% of food revenue annually. If your food cost% is consistently above target with no obvious operational explanation, restricted store access and increased stock count frequency are the first controls to implement.
How often should I check restaurant food cost percentage?
Weekly minimum — with a weekly stock check to calculate cost of ingredients sold accurately. Monthly food cost figures arrive too late to act on. Weekly tracking lets you catch a bad purchasing week before it compounds into a bad month.
What is the difference between food cost percentage and gross profit percentage?
They are inverses: Food Cost % + Food GP% = 100%. A 31% food cost gives you a 69% food gross profit. The UK food GP% target of 68–72% corresponds to a food cost target of 28–32%. See our full guide to restaurant GP% calculation.
