Controlling food costs comes down to the levers you actually own: how much you waste, how you price each dish, how tightly you manage stock and suppliers, and whether you price to a target food-cost percentage. You can't control beef prices or your electricity bill — but you can control the gap between what your ingredients cost and what your menu charges. This guide walks through how to do exactly that, with euro figures and a worked example you can apply this week.
Key takeaways
- Food inflation has eased, but the squeeze hasn't. Food and non-alcoholic beverage inflation fell from +4.6% in the year to June 2025 to +2.0% in the year to April 2026 (CSO, 2026) — yet four years of stacked rises pushed food costs from 28% to over 34% of turnover (RAI, 2025).
- Know your number first. You can't manage a food-cost percentage you don't measure. Calculate it monthly using opening stock, purchases and closing stock against food sales.
- Waste is the cheapest win. Irish restaurants and food services generate around 175,000 tonnes of food waste a year — 21% of the national total (EPA, 2025).
- Menu engineering protects margin without raising every price. Sort dishes by popularity and gross profit, then promote your stars and fix or cut your dogs.
- Price to a target, not to a feeling. Set a food-cost percentage you need to hit, cost every plate, and review pricing as supplier prices move.
What is actually happening to Irish food costs?
Food inflation has cooled, but the damage was already done. The headline rate for food and non-alcoholic beverages eased from +4.6% in the 12 months to June 2025 to +2.0% in the year to April 2026, while overall CPI rose 3.7% (CSO, 2026). So why does the bill still hurt?
Because a falling rate of increase isn't a fall in price. The damage is cumulative. The Restaurants Association of Ireland reports that since 2022, beef has risen by 96%, fruit and vegetables by nearly 50%, and chocolate by a staggering 157% (RAI, 2025). Even staples kept climbing into mid-2025: the CSO recorded a pound of butter up €1.10 to €4.83 and Irish cheddar up 95c to €11.34/kg in the year to June 2025 (CSO, 2025).
The result is a structural squeeze. Food costs now run at over 34% of turnover, up from 28%, and 65% of operators reported a decline in financial performance in 2024 (RAI, 2025). The point of this guide is the part you can do something about: rent, energy and wages are largely fixed, but food cost is the line you can actively manage.
What food-cost percentage should an Irish restaurant aim for?
A common industry benchmark is a food cost of around 28–35% of food sales — meaning a gross profit of roughly 65–72%. That is a general hospitality rule of thumb, not a regulated figure, and the right target depends on your format: a wet-led gastropub, a casual takeaway and a fine-dining room will all sit in different places. The Ireland-specific reality check is that the sector now averages over 34% of turnover on food (RAI, 2025) — so if you're above that, you're losing margin your competitors are keeping.
What matters more than hitting a magic number is knowing your number and moving it in the right direction. Below is how to calculate it, then five levers to bring it down.
Step 1: Track and calculate your food-cost percentage
Start here, because every other lever depends on it. Your food-cost percentage is your cost of goods sold divided by your food sales, over the same period:
Food cost % = (Opening stock + Purchases − Closing stock) ÷ Food sales × 100
Worked example for one month:
- Opening stock (value of food on hand at the start): €8,000
- Purchases (everything bought in): €22,000
- Closing stock (value of food on hand at the end): €7,000
- Cost of goods sold = 8,000 + 22,000 − 7,000 = €23,000
- Food sales for the month (excluding VAT): €70,000
- Food cost % = 23,000 ÷ 70,000 × 100 = 32.9%
Do this every month, not once a year. A monthly stocktake on the same day each period is the single discipline that turns food cost from a guess into a managed number. If the percentage drifts up two months running, you investigate before it becomes a habit. Track it alongside your other fixed-cost lines — many operators run it next to the energy, insurance and rent review covered in our guide to cutting Irish restaurant overheads.
Step 2: Cut waste first — it is the cheapest margin you have
Waste is the lever with the fastest payback, because every binned ingredient was bought at full price and earns nothing. Irish restaurants and food services generate around 175,000 tonnes of food waste a year — 21% of the national total of 835,000 tonnes (EPA, 2025). Nationally, Ireland wastes "over one million meals a day" (EPA, 2024). A meaningful share of that is commercial, and most of it is preventable.
Practical steps that move the number:
- Measure what you throw out. Keep a simple waste log by station for two weeks — spoilage, prep trim, over-production and plate returns. You can't cut what you don't see.
- Tighten ordering to your covers. Over-ordering perishables to "be safe" is how the walk-in fills up and the bin fills faster. Order to forecast, not to comfort.
- Use first-in, first-out (FIFO) religiously. Date and rotate stock so older product is used first.
- Re-engineer prep for trim. Carrot peelings, beef trim and bones become stock, staff meal or a special instead of waste.
- Right-size portions. Consistent, correctly portioned plates cut both food cost and plate returns — and a scale at the pass pays for itself.
Step 3: Engineer your menu around gross profit
Menu engineering means deciding what to sell, not just what to cook — and it protects margin without raising every price. Cost every dish to get its plate cost and gross profit in euro, then sort the menu into four groups by popularity and profitability:
- Stars — popular and high-margin. Feature them: prime menu position, server recommendations, photography.
- Workhorses — popular but low-margin. Tweak the recipe, portion or price to lift profit without killing demand.
- Puzzles — high-margin but slow sellers. Reposition, rename or describe them better, or move them to specials.
- Dogs — unpopular and low-margin. Cut them; they tie up stock, prep time and menu space.
Worked plate example: a main that costs €5.40 in ingredients and sells for €18 (excluding VAT) runs a 30% food cost and a €12.60 gross profit. The same dish at €4.80 of ingredients — achieved by swapping one premium component or tightening the portion — drops to 26.7% food cost and adds €0.60 of margin on every plate. Across a few hundred covers a week, that is real money.
The discipline is to keep costing dishes as supplier prices move. A recipe that worked at last year's beef price may be underwater now.
Step 4: Tighten supplier and stock control
Suppliers and stock are where small leaks add up to a big number. You buy from your suppliers every week, so even modest improvements compound:
- Review supplier pricing regularly. Get line-by-line pricing, compare across two or three suppliers, and re-tender your biggest spend lines at least twice a year. Loyalty is fine; blind loyalty is expensive.
- Check every delivery against the docket. Weigh and count what arrives. Short deliveries, substitutions and price creep on the invoice are common and quietly inflate your food cost.
- Consolidate where it earns you a better price, but keep a backup supplier for your critical lines so one shortage doesn't force a panic buy at retail prices.
- Lock your par levels. Set minimum and maximum stock for each line so you reorder to a number, not a hunch — this is what stops both stockouts and over-ordering.
- Secure high-value stock. Spirits, premium proteins and other "shrinkage-prone" items belong under tighter control and regular counts.
Step 5: Price to a target food-cost percentage — and review it
Pricing is the lever most owners under-use, because raising prices feels risky. The fix is to price to a target rather than to a feeling. Decide the food-cost percentage you need to hit, then set each price so the plate cost divided by the price lands on it. If your target is 30% and a dish costs €5.40, the floor price is €18 (5.40 ÷ 0.30).
Then revisit it. When a key ingredient jumps — as beef and dairy have — recost the affected dishes and adjust. You don't have to move every price; often it's enough to nudge a handful of high-volume items by 30–50c, or to redesign the dish, to recover the margin. Customers rarely notice a small, well-timed change across a few items; they always notice when a tired business finally hikes everything 15% at once.
Step 6: Protect the margin beyond the kitchen
Food cost isn't the only thing eating your gross profit — and it's worth closing the other leaks while you're at it. The most common one is delivery-app commission: at 14% to as much as 30% per order, an aggregator can cost you more on a transaction than the ingredients did. We break the maths down in our guide to what Deliveroo and Just Eat really cost Irish restaurants.
Encouraging direct orders is one of the cleanest ways to keep that margin. A simple, always-current online menu and ordering page on your own website lets regulars order without an aggregator's cut on top of your rising food cost — and modern tools like DineHere build one from a photo of your menu in minutes, so it's a job you set up once rather than a website you have to keep logging into. The principle is the same as everything above: control the costs you can actually control.
Frequently asked questions
What is a good food-cost percentage for a restaurant in Ireland?
A common industry benchmark is around 28–35% of food sales, but the right target depends on your format. The Irish sector currently averages over 34% of turnover on food (RAI, 2025), so anything well below that is a sign of strong control.
How do I calculate my food-cost percentage?
Use: (Opening stock + Purchases − Closing stock) ÷ Food sales × 100, over the same period. For example, €23,000 of cost of goods sold against €70,000 of food sales is a food cost of 32.9%. Run it monthly from a regular stocktake.
Why are my food costs still rising if inflation has fallen?
Because a lower inflation rate still means prices are rising, just more slowly — and they're rising from an already-high base. Food and non-alcoholic beverage inflation eased to +2.0% in the year to April 2026 (CSO, 2026), but since 2022 beef is up 96% and food cost has climbed from 28% to over 34% of turnover (RAI, 2025).
What is the fastest way to cut food costs?
Cutting waste, because every binned ingredient was already paid for. Start a two-week waste log by station, tighten ordering to your forecast covers, and enforce FIFO stock rotation. Irish restaurants and food services waste around 175,000 tonnes a year (EPA, 2025), most of it preventable.
What is menu engineering?
It's costing every dish for its gross profit, then sorting the menu by popularity and profitability into stars, workhorses, puzzles and dogs — so you promote what makes money and fix or cut what doesn't. It protects margin without raising every price.
How often should I do a stocktake?
Monthly at a minimum, on the same day each period, so your food-cost percentage is comparable month to month. High-value items like spirits and premium proteins benefit from more frequent counts.
Should I raise my prices or cut my costs first?
Do both, but measure first. Recost your dishes as ingredient prices move, then decide whether to adjust the recipe, the portion or the price. Small, well-timed changes on high-volume items recover margin with less customer pushback than an across-the-board hike.
How do delivery apps affect my food costs?
They don't change your ingredient cost, but commissions of 14–30% per order erode the gross profit those ingredients earn — sometimes by more than the food cost itself. Encouraging direct orders protects that margin; see our Deliveroo and Just Eat cost breakdown.
How do I reduce food waste in a busy kitchen?
Measure it first with a waste log, order to forecast rather than "to be safe", rotate stock FIFO, repurpose trim into stock or specials, and standardise portions. Most kitchen waste is over-production and prep trim, both of which respond quickly to tighter routines.
What other costs should I tackle alongside food cost?
Energy, insurance, rent and waste-collection charges are the other big levers — many are re-tenderable. Our overheads guide covers nine of them, and delivery-app commission is often the largest hidden leak of all.
