How to Price a Sandwich or Coffee and Actually Make a Profit in a UK Cafe

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 30–35%), 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.

Start with the actual cost of one item

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:

• Coffee beans — a double shot is roughly 18–20g. At £20/kg of beans, that's about 36–40p per drink.
• Milk — a flat white uses around 150ml of steamed milk. At 80p/litre, that's about 12p. A latte uses more.
• Cup, lid, sleeve — for takeaway, 12–18p depending on quality.
• Sugar, stirrer, napkin — call it 2–3p.

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":

• 2 slices of sourdough at £2.20/loaf (12 slices) = ~37p
• 80g of cheddar at £7/kg = 56p
• 40g of ham at £9/kg = 36p
• Butter, salad, mayo = ~25p
• Packaging (if takeaway) = 15–30p

That's roughly £1.70–£1.85 for the sandwich. Build a similar breakdown for every item you sell.

Apply your target food cost percentage

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:

• Sandwich costing £1.80 ÷ 0.30 = £6.00
• Flat white costing £0.55 ÷ 0.30 = £1.83

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.

Don't forget VAT — it changes everything

This is where UK cafes get caught out. VAT (currently 20%) applies to:

• All hot drinks — eat in or takeaway
• Hot food — eat in or takeaway
• Anything eaten on the premises — including a cold sandwich eaten at your table

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.

Cover the costs that aren't on the plate

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:

• Food/drink cost: 28%
• Labour: 30%
• Overheads: 25%
• Net profit: ~15%

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.

Price for the margin you keep, not the price that looks fair

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.

Build a prep sheet, then re-cost it every season

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:

• Cost recipes by weight, not by eye.
• Track yield — a roast chicken loses weight when cooked; cost the usable yield, not the raw bird.
• Re-cost quarterly or whenever a supplier price changes.
• Scale your batches so a tray of 24 sandwiches reflects real per-unit cost, including the offcuts.

This is exactly the kind of admin that gets skipped because it's tedious in a spreadsheet — and skipping it is where margins disappear.
