To price a sandwich or coffee profitably in a UK cafe, work out your food cost per item, divide it by your target food cost percentage (usually 25–35%), and add VAT where it applies. For most cafes that means a sandwich costing you £1.80 in ingredients should sell for around £5.50–£6.50, and a flat white costing you 45–55p should sell for £3.00–£3.50. The exact number depends on your rent, labour, waste, and how busy you are — but those ratios are where you start.
Here's how to do it properly, without guessing.
Most cafe owners price by looking at what the place down the road charges. That's a guess, not a strategy. Real pricing starts by costing a single portion.
For a coffee, add up:
So a takeaway flat white costs you roughly 55–70p in raw materials. Dine-in (no disposable cup) is cheaper, around 45–55p.
For a sandwich, cost every component by weight, not by "a bit of this":
That's roughly £1.70–£1.85 for the sandwich. Build a similar breakdown for every item you sell.
Once you know the cost of one item, divide it by your target food cost percentage to get your selling price (excluding VAT):
Selling price = item cost ÷ target food cost %
A common UK cafe target is 30% food cost, meaning ingredients should be about a third of the price. So:
Coffee almost always runs at a lower food cost than 30% — often 18–22% — because the market will bear it and the margin subsidises lower-margin food. That's why a flat white that costs you 55p sells for £3.30, not £1.83. Coffee is your profit engine. Food builds footfall and average spend.
This is where UK cafes get caught out. VAT (currently 20%) applies to:
A cold sandwich taken away is zero-rated for VAT. So the same sandwich can carry very different real margins depending on where the customer eats it.
If you're VAT-registered, your menu price includes VAT, and you hand 1/6th of every hot-drink sale to HMRC. A £3.30 coffee gives you £2.75 of actual revenue. You must cost against the ex-VAT price, or your margins are an illusion.
Quick rule: to find the ex-VAT figure from a VAT-inclusive price, divide by 1.2. £3.30 ÷ 1.2 = £2.75.
Food cost percentage only covers ingredients. Your real profit has to survive three other big costs:
1. Labour — typically 25–35% of revenue in a cafe. With the National Living Wage rising, this is the number that quietly kills margins.
2. Fixed overheads — rent, business rates, utilities, insurance, card fees, cleaning. Often 20–25%.
3. Waste and shrinkage — prepped sandwiches that don't sell, milk that goes off, mistakes. Budget 4–8%.
A rough healthy cafe P&L looks like:
If your food cost creeps to 38% and labour to 35%, you're losing money on every busy day and don't realise until the quarterly accounts arrive.
Two practical adjustments make a real difference:
Round up with confidence. If the maths says £5.80, charge £6.00. Customers don't notice 20p, but across 80 sandwiches a day that's £16 — over £4,000 a year of pure profit on one line.
Use anchor and add-ons. A £3.30 coffee feels normal next to a £4.50 speciality drink. A 60p extra shot or 50p oat milk costs you pennies and lands almost entirely as profit. These upsells often matter more than the base price.
The biggest pricing mistake isn't the first calculation — it's never doing it again. Ingredient prices in the UK have moved sharply: butter, cheese, coffee beans and energy have all jumped. A sandwich you costed at £1.80 eighteen months ago might cost £2.30 today, quietly turning a 30% food cost into 38%.
To stay on top of it:
This is exactly the kind of admin that gets skipped because it's tedious in a spreadsheet — and skipping it is where margins disappear.
