Optimising Food Cost: Reducing Goods Cost Without Sacrificing Quality

Goods cost is the largest variable expense block in the restaurant industry. Labour costs are often harder to move in the short term — collective agreements, employment contracts, and the structural skills shortage leave little room. Food cost, by contrast, has slack in most businesses that goes untapped — not through negligence, but because day-to-day operations leave little time for systematic analysis.

This article describes concrete measures for food cost optimisation. Not abstract recommendations, but steps that can be applied in practice.

What Is Food Cost — and What Is a Good Figure?

Food cost is the ratio of goods cost to revenue, expressed as a percentage:

Food cost (%) = goods cost / net revenue × 100

A business with €10,000 net revenue and €3,000 goods cost has a food cost of 30%.

Benchmark figures in hospitality:

• Full-service restaurant: 28–35%
• Quick service / snack bar: 25–30%
• Fine dining: 30–40% (higher goods cost, higher margins through price positioning)
• Catering: 30–38%

These benchmarks are reference points, not laws of nature. What matters is not the absolute figure, but whether it is proportionate to the concept — and whether it is actually known. Many operators estimate their food cost; they do not know it monthly from reliable figures.

Step 1: Measure Before Optimising

Every measure is ineffective without a baseline. Food cost cannot be optimised from gut feeling alone.

Inventory as the Foundation

Anyone who genuinely wants to know their food cost runs a monthly stock-take. That sounds onerous, but for most businesses it is achievable in half a day if items are systematically recorded. Without a stock-take, the goods cost calculation is inaccurate — too much purchased in the previous month, too little consumed, all of which distorts the figure.

Formula with stock-take: Goods cost = opening stock + purchases − closing stock

Product-Group Analysis

Not every product group has the same food cost. Meat and fish typically carry higher goods costs than side dishes or soups. When the overall figure is too high, it helps to know which product group is driving it.

POS systems with an inventory module can provide this breakdown. Businesses without an integrated inventory system can at least build a rough product-group split from supplier invoices.

Step 2: Recipe Costing — What Is Actually Being Earned

A common problem in restaurant businesses: menu prices have grown historically. A dish has cost €14.90 for years because it always has — not because a current calculation produces that figure.

Recipe-Based Costing

Every dish should have a raw-ingredient calculation: which ingredients are used in what quantity, at what current purchase price? The result is the goods cost per portion.

Example (simplified):

• 200g chicken breast: €1.80
• 150g vegetables: €0.60
• Side dishes, seasoning: €0.40
• Total: €2.80

At a selling price of €13.90 (net), food cost for this dish is 20.1%. That is good. If the same dish cost €8.90, food cost would be 31.5% — still acceptable, but noticeably less profitable.

Many businesses regard this calculation as too labour-intensive. In practice, a spreadsheet covering the main dishes is sufficient. Whoever finds the largest deviations from the target food cost there has concrete starting points.

Price Adjustments for Rising Purchase Prices

Raw material prices change. Businesses that last calculated their menu in 2022 are working from outdated figures. Meat and fish prices, oil, energy for preparation — many input costs have risen, and not all have been passed through to the menu.

An annual calculation review — or triggered by significant price changes from the main supplier — is not an optional measure; it is basic commercial hygiene.

Step 3: Implement Portioning Consistently

Portioning errors are invisible but cost-relevant. If a dish is calculated with 200g of meat and the team routinely serves 230g, the actual food cost is 15% above the calculated figure. At high throughput, this accumulates considerably over the course of a month.

Scales and Aids

Portioning scales, pre-portioned ingredients, standardised containers for side dishes — this sounds like industrial catering, but is equally appropriate in restaurants. A chef with ten years of experience portions by eye reliably. A temporary or substitute who joined two weeks ago does not.

A snack bar operator in North Rhine-Westphalia standardised portioning of kebab ingredients — meat, salad, sauces — through prepared containers. The result was not only a more consistent food cost but a more consistent product. Regular customers complained less frequently about varying portion sizes.

Accounting for Trimming and Processing Losses

Fresh ingredients incur losses through cleaning, cutting, and cooking. 1 kg of raw potatoes yields around 700–750g after peeling and cooking. Anyone calculating 1 kg of ingredients at purchase price but only able to process 750g is calculating incorrectly.

Processing losses (yield) must be factored into recipe calculations. This is particularly relevant for meat and fish, where trimming losses can vary significantly depending on quality and supplier.

Step 4: Review Supplier Strategy

“We’ve had the same butcher for ten years” is frequently heard in hospitality. Supplier loyalty is not inherently wrong — reliability and quality have value. But a regular comparison of terms is not disloyalty; it is professional procurement management.

Comparing Without Unnecessary Effort

A comparison does not need to be a full tender every time. Three times a year, request quotes for the most important lines — meat, fish, staple ingredients — from an alternative supplier and compare. This gives a picture of whether purchasing is at market rates.

Cash-and-carry wholesalers (e.g. Metro, Selgros) can also be cheaper for certain product groups than delivery services — without the benefit of delivery. Businesses with the logistical capacity to purchase from a mix of sources often save 5–10% on standard items.

Optimising Order Frequency

Frequent small orders increase workload and sometimes costs. Many suppliers have minimum order values or charge delivery fees for small quantities. A structured ordering schedule — twice a week rather than daily — reduces transaction costs and enables better quantity planning.

Too infrequent ordering, on the other hand, leads to excess stock that results in spoilage. The right frequency depends on the concept, storage capacity, and shelf life of the ingredients.

Step 5: Menu Rationalisation

A long menu has tradition in hospitality. It also has disadvantages: more ingredients to stock, more spoilage, more complex mise en place, greater cognitive load on the kitchen team.

ABC Analysis for the Menu

POS systems with analytics functions show which dishes are ordered how often. A typical distribution has 20% of dishes accounting for 80% of revenue.

Dishes that are ordered infrequently and simultaneously carry high goods costs or complex preparation are candidates for removal. This is a decision that operationally tends to meet resistance (“But some people like it”), yet can make economic sense.

A rule of thumb: if a dish is ordered fewer than once a week and requires specialist ingredients used only for that dish, its contribution to the menu is not worth the effort.

Seasonal Menus Reduce Permanent Overhead

Seasonal dishes have the advantage that seasonal ingredients are cheaper. They have the disadvantage that a menu change means training effort. A good balance: a stable core range plus a handful of seasonal additions.

What Does Not Work: Quality Cuts as a Measure

Food cost optimisation does not mean buying cheaper raw materials without understanding the quality impact. Cheaper meat often has different water content, different cooking behaviour, and a different flavour. If guests notice, it shows up in reviews — damage that is harder to quantify than the goods cost saved.

A more sensible approach: make quality decisions consciously and with documentation. When an alternative product is introduced, define clear criteria for the minimum quality requirement — and verify these before the product is used permanently.

Conclusion: Food Cost Optimisation Is a Process, Not a One-Off

The measures described here — recipe costing, portioning, supplier comparison, menu rationalisation — only work if applied systematically and regularly. A one-off calculation review two years ago contributes nothing today.

Businesses that know their food cost figures monthly, review their calculations quarterly, and rationalise their menu annually have a foundation on which sound decisions are possible. This is not an effort that paralyses the business — it is a few hours per month that pays off in any business with sufficient volume.

The most important measure is the first: start measuring.
