Costing
If you don't know what a dish costs, you don't know what it earns
The price on the menu is a guess until you know the cost behind it. Costing a recipe takes a few minutes — and it changes every pricing decision you make afterwards.
The evidence base
The costing mechanics here are arithmetic you can check against your own invoices. The scale of what's at stake is measured, and comes from:
- WRAP — the UK's food-waste body: what waste costs the hospitality sector, per year and per outlet. See [1]
- WRAP's sector waste audit — where hospitality food waste actually arises: preparation, spoilage and the plate. See [2]
- HMRC VAT Notice 709/1 — the official rule that catering is standard-rated, so margin is earned on the price after VAT. See [3]
- Marn & Rosiello (1992) — the classic Harvard Business Review analysis of how hard a small price or cost move hits operating profit. See [4]
No public dataset records how many operators cost their recipes, so this piece doesn't claim one. It sticks to what the sources above measure: the cost of waste, the VAT rules and the profit leverage of a few points of margin.
There's a number most menus are missing, and it's hiding in plain sight. Not the price — everyone has a price. The cost. Plenty of good operators set prices by glancing at the competition, rounding to a tidy figure, or carrying last year's number forward. That decides what the dish brings in. It says nothing about what's left underneath.
Cost is more than the ingredients
The sticker price of the ingredients is only the start. By the time a dish reaches a plate, several quieter costs have taken a bite out of it:
- Waste and trim — you buy a whole thing and use part of it. The bit you bin is still cost.
- Packaging — boxes, lids, cutlery and bags, especially for takeaway and delivery, add up fast.
- VAT — the headline price includes it; your margin is calculated on what's left after it comes out.[3]
- Royalty or commission — if your business pays one, it comes off every single sale.
The waste line alone deserves respect: food waste costs UK hospitality about £3.2 billion a year — roughly £10,000 per outlet[1] — and WRAP's sector audit found 45% of it arises in preparation, before a plate ever reaches a guest.[2] Trim, spoilage and over-prep are not a rounding error; they are a cost line.
Add those in and a dish that looked like a comfortable 70% gross profit on the ingredients alone can turn out to be a good deal thinner. The margin you think you have and the margin you actually keep are rarely the same number.
Cost once, decide for the life of the dish
The good news is it's a one-off effort with a long payoff. Once you know what a dish truly costs, you can set its price to hit a target margin instead of hoping. You can see at a glance which dishes don't earn their place on the menu. And when a supplier raises a price — as they always do — you can see in seconds what it does to your gross profit, rather than finding out at the month end.
A few minutes that protects the year
A few points of gross profit on every dish is the difference between a comfortable year and a hard one. That is not rhetoric: the classic HBR analysis puts a 1% improvement in realised price at roughly an 11% lift in operating profit for a typical large company — and mis-costing works the same lever in reverse.[4] With so little room to spare, knowing your true cost is what turns pricing from a hopeful round-number into a deliberate decision. It's the protection that lets you stay profitable when costs move, instead of being moved by them.

Enter the ingredients, add a waste allowance and packaging, then set your price and target. The recipe cost calculator works out the true plate cost, your gross profit, and whether the dish is within budget — for food or drink. Toggle a royalty or commission on if you pay one.
