TLDR: Menu costing is where profit starts or disappears. If you’re still estimating, you’re bleeding margin.
Introduction
Costing isn’t admin. It’s survival. If you don’t know what every dish actually costs, you’re gambling with your business. Our costing sheet gives chefs instant clarity, what to charge, what to fix, and where you’re losing money. Used right, it changes how you build menus.

1. Why Costing Still Gets Ignored
Most chefs think they can guess. Or round up. Or use last year’s numbers. That worked when margins were fat. Today, it’s reckless. Pricing without real costing turns kitchens into busy loss-makers.
A chef in Glasgow switched from guesswork to this sheet and caught £900 in missing margin on one menu cycle.

- Dish Costing Tab – Enter ingredients, units, prices, yield, and it calculates cost per portion.

- Repeat for every dish. Then adjust.
4. Example: Flash Food Costing In Action
Here’s a quick formula any chef can use, anytime:
(Ingredient Cost ÷ Yield) × Portion Size = Cost per Portion
Example: £18 lamb shoulder ÷ 10 = £1.80 per portion.
Add £0.30 veg + £0.20 seasoning + £0.15 oil + £0.25 packaging = £2.70 total cost.
Charging £10? After VAT and labour, you’re not making much.
5. AI Prompt for Instant Costing Help
“Give me the cost per portion for a dish using 2kg of lamb at £9/kg, 300g of veg at £1.20/kg, £2 spices, and £1.50 in packaging. Yields 10 portions.”
Paste this into ChatGPT and get your figures instantly. It’s not cheating. It’s efficient.
6. Real Costs You’re Probably Missing
Too many chefs forget the small stuff. But they add up fast:
- Seasoning – Salt, pepper, spice blends
- Oil – Fryer top-ups, finishing oils
- Packaging – Takeaway boxes, foil, containers
- Service Add-ons – Napkins, cutlery, condiments
Ignore them, and your ‘cost per dish’ becomes fantasy.

What is a good food cost percentage for chefs in the UK?
A typical food cost target for chefs in the UK is 28–32%. This allows room for profit after accounting for labour, overheads, and VAT, while still delivering high-quality dishes.
How can I calculate recipe costs quickly without software?
Use a basic formula: Ingredient Cost ÷ Portion Yield = Cost per Portion. Or use a free AI prompt to itemise by weight, price, and yield. Just make sure to include extras like oil, salt, napkins, and takeaway packaging.
What should chefs include in their costing sheets besides ingredients?
Costing sheets should also cover cooking oils, seasoning, garnishes, packaging, napkins, condiments, and any extras like bread or butter. These add up fast and eat into margin if left out.
