Managing Food Costs: Templates That Help

Why this matters

Cafes live and die on margins thinner than most owners realise. A flat white might sell for £3.80, but once you’ve counted the milk, the cup, the lid, the sleeve, the coffee, and the 12% of shots that get poured down the sink during dial-in, the margin is not what you think. And pastries, the other half of most cafes’ revenue, spoil daily by design. Cafe food cost isn’t one big problem; it’s a hundred small leaks. Finding them requires the same discipline as a restaurant, applied to smaller numbers that add up fast at volume.

Practical steps

1. Know your true cost per drink

Coffee margins look generous until you do the maths properly. Cost out each drink:

  • Coffee: grams per shot × cost per kilo of beans. A 18g double shot from £22/kg beans costs about 40p, but re-cost when bean prices move, because they do, often.
  • Milk: millilitres per drink × cost per litre, per milk type. Oat milk typically costs 2–3× dairy, if your oat flat white is priced the same as dairy, you’re donating margin on every one.
  • The cup, lid, sleeve, napkin, and stirrer for takeaway drinks. Packaging on a takeaway coffee routinely costs 25–40p, that’s 10% of a £3.50 sale before you’ve poured anything.
  • Waste: dial-in shots, remade drinks, spilled milk. Track it for a week and add a waste percentage to every drink cost. Most cafes waste 5–10% of coffee; pretending it’s zero just hides the loss.

Once you have the true cost, check your prices. The drink with the worst margin is usually the large takeaway with alternative milk, exactly the drink your regulars order most.

2. Attack pastry and food waste, it’s your biggest leak

Day-old pastries are the cafe’s structural waste problem. You can’t sell yesterday’s croissant, and you can’t perfectly predict today’s demand:

  • Log daily waste: what, how many, value. “12 croissants binned” means nothing; “12 croissants = £14.40 cost, £42 in lost revenue” drives decisions.
  • Track waste against weather, day of week, and local events. Patterns emerge fast, rainy Tuesdays need a smaller order, market Saturdays need more.
  • Negotiate with your bakery supplier: smaller, more frequent deliveries beat one big daily drop if waste is high. And ask about a stale-stock policy, some suppliers credit or discount day-old product.
  • Consider end-of-day discounting rather than binning. Selling at half price recovers cost; the bin recovers nothing. (Check your local food safety regulations on time limits for displayed food first.)

3. Compare suppliers quarterly

Cafes tend to stay loyal to their roaster, often rightly, since coffee defines the brand. But loyalty should be a choice, not a habit:

  • Beans: get a quote from one other roaster per quarter. Even if you stay, the quote is negotiating leverage.
  • Milk and alternatives: these are commodities with real price spread between suppliers. A penny a litre across hundreds of litres a week is real money.
  • Pastries and cakes: compare on price per unit and waste rates. A cheaper croissant that goes stale by noon is more expensive than a better one that sells through.
  • Always compare delivered cost, delivery charges and minimum orders included.

4. Watch the small numbers monthly

Once a month, review: total food and beverage purchases vs. revenue, waste log totals, and margin per drink category. In a cafe this is a 20-minute job, the numbers are small enough to hold in your head, which is exactly why owners skip it and let the leaks run for a year.

Common mistakes

  1. Pricing alternative-milk drinks the same as dairy. Oat and soy cost multiples of dairy milk. If there’s no price difference on your menu, every alternative-milk drink is a margin donation. Charge for it, customers expect it.
  2. Forgetting packaging in drink costs. The cup, lid, and sleeve are part of the product cost. Cafes that cost “coffee + milk” and ignore 35p of packaging are understating every takeaway drink by ~10%.
  3. Ordering pastries on gut feel. “We usually sell about that many” is not a ordering system. Two weeks of waste logs turn gut feel into data, and the data almost always says: order less on weekdays.
  4. Never re-costing after supplier price rises. Milk goes up 3p a litre and nobody updates anything. Across a thousand drinks a week, that’s £30 a week, £1,500 a year, silently gone.

Templates that help

Bottom line

Cafe margins are made or lost in pennies per drink and pastries per day. Cost every drink including packaging and waste, log pastry waste with values attached, and check supplier prices quarterly. The cafes that survive aren’t the ones with the best coffee, they’re the ones that know what each cup actually costs.
