Understanding Pub COGS in the UK: The Operator’s 2026 Guide

Last updated: 12 April 2026

Most UK pub landlords throw away £2,000 to £5,000 a year without realising it—and the culprit isn’t theft or waste. It’s a misunderstanding of cost of goods sold (COGS). You can run a packed bar, serve good food, and still lose money because you’re calculating your margins wrong. This guide shows you exactly what COGS is, what belongs in it, how to calculate it for pubs (which is different from restaurants), and how to use it to actually fix profit leaks. By the end, you’ll know whether your pub is performing at industry standard or if you’re leaving money on the table every single week.

What Is Cost of Goods Sold for Pubs?

Cost of goods sold (COGS) is the total cost of the drinks and food your pub sells during a period. It’s the starting material cost before any staff time, overheads, or profit. Understanding COGS is the foundation of understanding your real margins.

In a pub context, COGS includes:

• Draught beer, lager, cider, and stout purchased from your supplier
• Bottled and canned drinks (beer, soft drinks, energy drinks)
• Spirits and liqueurs
• Wine (by the glass and bottle)
• Mixers, juices, and cordials
• Food ingredients and prepared meals (if you serve food)
• Non-alcoholic beverages (coffee, tea, soft drinks sold at retail)

COGS does not include:

• Staff wages or National Insurance
• Rent or mortgage
• Utilities (electric, gas, water)
• Marketing or advertising
• Equipment or furniture
• Insurance or professional fees
• Licenses or compliance costs

Why does this matter? Because if you’re calculating your profit margin and you accidentally include labour costs in COGS, you’ll think your margins are worse than they actually are. You’ll make wrong decisions about pricing, supplier negotiations, or menu mix. I’ve watched licensees cut their food offering entirely because they thought their COGS was 45% when it was actually 32%—they’d just miscategorized their kitchen wages.

A pub profit margin calculator that separates COGS from operating expenses will catch this mistake immediately.

What Actually Goes Into Pub COGS

This is where most operators go wrong. They think COGS is simple. It’s not—not because the concept is hard, but because pubs have complex supply chains.

Opening Stock + Purchases − Closing Stock = COGS

The formula is straightforward, but the execution determines whether you’re profitable or not.

Let’s say it’s the end of January:

• Opening stock (1 January): You did a full cellar audit and dry stores count. Total cost of all drinks and food in the building: £8,200
• Purchases (January 1–31): All supplier invoices for drinks and food delivered in January: £12,500
• Closing stock (31 January): You count everything again. Total value: £7,800
• COGS = £8,200 + £12,500 − £7,800 = £12,900

If your January sales were £38,000 (drinks and food revenue combined), your COGS percentage is £12,900 ÷ £38,000 = 33.9%.

Industry standard for a wet-led pub is 28–32%. You’re at 33.9%, which means you’re leaking money. Not much—maybe £300 that month. But across a year, that’s £3,600. Over five years, £18,000.

The problem is the closing stock count. If you got it wrong by just £300 (which happens when you skip the top shelves or don’t count the kitchen dry store properly), your COGS drops to 31.8% and suddenly you look like you’re performing. You’re not. You’re just measuring wrong.

Why Closing Stock Matters More Than Opening Stock

When I audit stock at Teal Farm Pub in Washington, Tyne & Wear—a busy venue handling wet sales, dry sales, quiz nights, and match day events—the cellar count is where I find the most errors. Most operators count the bars and till points accurately but skip the cellar because it takes time and feels less immediate.

Here’s what gets missed:

• Empty bottles and casks still on the racks (cost already paid, shouldn’t be counted as closing stock)
• Damaged or expired stock (should be written off, not counted)
• Stock held in the kitchen that was never entered into the bar system
• Promotional stock or staff drinks (if you’re accounting for these separately, which you should)
• Spirits in optics that haven’t been rung through the till yet

If your EPOS system doesn’t integrate with your cellar management, you’re doing this manually. Manual processes create gaps. That’s why pub IT solutions that link your till to your stock system save time and accuracy.

How to Calculate Your Pub COGS

Here’s the real process, step by step.

Step 1: Decide Your Accounting Period

Monthly is standard for pubs. Weekly is too granular and creates too much counting work. Quarterly misses too much variation. Monthly lets you spot trends and fix problems quickly.

Step 2: Count Opening Stock

At the start of your period (usually the first trading day of the month), count everything:

• Every bottle, keg, and cask in the cellar
• Every spirit optic and measure behind the bar
• Every can, bottle, and carton in the dry store and kitchen
• Wine racks (by bottle and partial bottles opened during the period)

Assign a cost to each item based on your last supplier invoice. If you bought a case of lager at £28 and you have 6 bottles left, that’s £4.67 per bottle. Do this for everything.

Total this up. That’s your opening stock value.

Step 3: Record All Purchases

Every invoice from every supplier goes on the list. Your main beverage supplier, your food supplier, your specialist wine merchant, your cash-and-carry runs—all of it. Total it all up.

One mistake: some operators include non-COGS items on supplier invoices (new glassware, cleaning chemicals, staff uniforms). These should be removed and categorised as overheads or assets, not COGS.

Step 4: Count Closing Stock

At the end of your period, count everything again using the same method. This is where accuracy matters most.

Step 5: Calculate COGS

Opening stock + Purchases − Closing stock = COGS.

Then: COGS ÷ Total Revenue = COGS %

Record this. Month after month. You’re building a data series that shows you whether your margins are stable, improving, or deteriorating.

COGS for Wet-Led vs Food-Led Pubs

Wet-led pubs and food-led pubs have completely different COGS profiles, and most comparison sites miss this entirely. This is critical because it determines whether you’re actually performing well or not.

Wet-Led Pubs (Mostly Drinks, Little or No Food)

Industry benchmark: 25–32% COGS.

A wet-led pub focuses on draught, spirits, wines, and packaged drinks. Food might be crisps, nuts, or microwaved snacks—low-cost, high-margin items.

When you’re selling primarily drinks with high markup potential, your COGS should be lower because:

• Draught margins are typically 65–75% (you buy a pint at £0.90 and sell it at £3.50)
• Spirit margins are 70–80% (bottle costs £15, you sell 25 measures at £2.80 each)
• Snacks are bought at cost but sold at high margins (£0.50 bag of crisps sells for £1.20)

If your wet-led pub is running COGS at 35%, you have a problem. Either your supplier costs are too high, your pricing is too low, or you have significant stock loss (waste, theft, or measurement error).

Food-Led Pubs and Gastropubs

Industry benchmark: 28–35% COGS.

A food-led pub generates significant revenue from meals—think jacket potatoes, pies, burgers, salads. Food has much lower margins than drinks (typically 60–70% vs 70–80% for drinks), so your overall COGS will be higher.

Why? Because food ingredients cost more relative to selling price. A portion of fish and chips might cost £2.80 to produce and sell for £9.50 (a 71% margin), whereas a pint of draught costs £0.90 and sells for £3.50 (a 74% margin). The difference is small but compounds across hundreds of transactions.

A food-led pub at 36% COGS is performing normally. A wet-led pub at 36% COGS is bleeding money.

When you use a pub drink pricing calculator, make sure it accounts for your pub type, because the benchmark changes everything.

Benchmarking Your COGS Against Industry Standards

Now you know what COGS is and how to calculate it. The question becomes: is yours any good?

The British Institute of Innkeeping publishes regular data on pub performance, and while the benchmarks shift year to year, the structure is consistent:

Wet-led pubs typically see COGS of 25–32%. This means for every £100 of drinks sold, you’re spending £25–£32 on the actual drinks. The rest covers labour, rent, utilities, profit, and everything else.

Food-led pubs and gastropubs typically see COGS of 28–35%. Higher because food margins are lower.

High-volume, low-margin operations (chain pubs, Wetherspoon-style venues) often run 20–25% COGS. They achieve this through massive supplier negotiation power and efficient portion control. You probably can’t match them.

The question is not “what is the benchmark?” but “what is the benchmark for my type of pub in my location?” A wet-led pub in Central London will have different supplier costs and pricing power than a wet-led pub in a market town. You need to know your own benchmark, then see if you’re above or below it.

If you’re consistently above benchmark, investigate these areas:

• Supplier pricing: Are your unit costs competitive? Talk to other licensees off the record. Call three competing suppliers and ask for quotes.
• Waste and stock loss: Are you counting stock accurately or missing spillage, spillage, breakage, and theft?
• Menu mix: Are you selling enough high-margin items or too many low-margin specials?
• Portion control: Are kitchen staff giving away portions larger than the recipe card calls for?
• Till accuracy: Is every drink rung through or are staff giving away free pints?

Practical Ways to Improve Your COGS

Lowering COGS is not about cutting costs. It’s about optimising what you sell, how much you pay for it, and how much waste you lose.

Negotiate Supplier Terms

Your main beverages supplier has flexibility. They’re not going to change their base price dramatically, but they can offer:

• Volume discounts: If you commit to higher purchases or longer terms
• Free goods: 1 free case per 10 ordered (common practice)
• Marketing support: Joint promotion budgets that reduce your advertising spend
• Shelf space rental: Some suppliers will discount products if you guarantee space and visibility

A 2–3% reduction in your per-unit cost on your top 10 products (the ones that drive 70% of your revenue) saves thousands a year. Don’t accept “that’s our price”—push back.

Implement Portion Control

Food waste happens in two places: in the kitchen and on the plate.

In the kitchen, establish a recipe card for every dish. Specify:

• Exact ingredients and quantities
• Cooking method and temperature
• Expected portion weight or size
• Cost per portion and selling price

Print these and laminate them at the pass. Your kitchen staff need to see them daily. When I evaluated EPOS systems for Teal Farm Pub, the test was simple: could the system track which staff members ring which dishes, and flag when portion size drifts? Most couldn’t. That visibility is where money gets found.

For drinks, this is easier—a standard spirit measure is a standard measure. But free pours are a disaster. Train staff to use jiggers, optics, and electronic measures. A single free pour given away each shift—just one—costs you £900 a year.

Reduce Stock Waste

Stock loss happens through:

• Spillage and breakage: Normal in a busy pub. Can’t eliminate, but can reduce through staff training and non-slip flooring.
• Evaporation: Draught kegs lose product through the line. Check your draught system annually.
• Expired stock: Implement FIFO (first in, first out) in your kitchen. Old stock gets used first. Train staff to check dates.
• Theft: Real, underestimated, and often internal. Mystery shopper programmes and regular till audits help.
• Measurement error: Your stock count is off. Do it again more carefully. Train whoever does it.

A well-run cellar loses 2–3% of stock to waste. A poorly-run cellar loses 5–8%. That difference is £50–£100 a month in a medium pub. Over a year, that’s £600–£1,200.

Optimise Menu Mix

Not all drinks and dishes are equal. Some have much higher margins than others.

Identify your top 20% of products by revenue. Calculate the margin on each. Are you selling lots of low-margin items and few high-margin items? If so, adjust:

• Price the high-margin items more prominently on the menu
• Train staff to recommend them first (“Can I start you off with a spirit?”)
• Bundle them with lower-margin items
• Reduce portion size on low-margin items or phase them out entirely

A premium lager costs you £0.95 and sells for £3.80 (75% margin). A budget lager costs you £0.75 and sells for £3.20 (77% margin). The budget has a slightly better margin, but the premium has higher absolute profit. Sell more premium, and your overall COGS improves.

Use Technology to Track Margin Drift

When you’re managing 17 staff across FOH and kitchen at Teal Farm, manual stock counts and margin calculations become impossible to do consistently. An pub management software system that integrates your EPOS, cellar management, and supplier invoicing does this automatically.

You should see, every single day:

• Yesterday’s COGS percentage vs last week vs last month vs last year
• Which products have drift (costing more than expected)
• Which staff ring which products (to spot free pours)
• Waste reports by product type

Real-world pressure during peak trading—a Saturday night with a full house, card-only payments, kitchen tickets, and bar tabs running simultaneously—is where margins either hold or collapse. Most systems that look good in a demo struggle when three staff are hitting the same terminal during last orders. That real-world performance is where this matters.

Common Objections to COGS Management

My Current Till Works Fine, Why Change It?

Your current till probably records sales accurately. It probably doesn’t tell you anything useful about COGS. It doesn’t integrate with stock counts, doesn’t flag portion drift, doesn’t track waste by product. A till that “works fine” for sales recording might be costing you thousands in margin leaks.

COGS Management Sounds Complicated

The formula is simple. The execution requires discipline, not complexity. One person does the monthly count. One person enters purchases. One calculation. You don’t need an accountant. You need a system and consistency.

Is It Worth Doing for a Wet-Led Only Pub with No Food?

Yes. Especially. Food-led pubs have higher COGS naturally, so a percentage point variation is less noticeable. In a wet-led pub, a single percentage point is hundreds of pounds a month. Wet-led pubs need COGS discipline more than anyone.

My Pubco Tells Me What My COGS Should Be

Your pubco gives you a benchmark, not a constraint. They’re not incentivised to help you optimise—they want you to buy at their price. Track your own COGS independently. Use it in negotiations. If they’re telling you your COGS should be 35% and you’re at 28%, you’ve found negotiation leverage.
