Setting a restaurant price isn't guessing what someone might pay. It's working out what each ingredient costs you, deciding how much profit you need, and building a price that covers both. The difference between getting it right and getting it wrong is the difference between keeping real money at the end of the month and wondering why there's nothing left.
This article walks you through the method step by step: how to calculate ingredient cost, how to choose your margin, and how to build the final price with arithmetic you can check yourself.
Calculate the real ingredient cost of each dish
Start with one dish. Write down every ingredient you use and how much of each. No guesswork: weigh the tomato, measure the oil, count the olives. Then note what each ingredient costs you per unit (per kilo, per litre, per dozen) from your last supplier invoice.
Multiply the quantity you use by the unit price. Add up all the ingredients. That total is the ingredient cost of the dish. It doesn't include gas, rent or labour yet — just the raw material that goes on the plate.
Example: imagine you're making a Spanish omelette. You use a handful of potatoes, some eggs, a little oil and salt. You look up what you paid per kilo of potatoes, per dozen eggs and per litre of oil on the invoice. You weigh what you actually use, do the multiplication and add it up. That's your ingredient cost.
Decide your target profit margin
The margin is the part of the selling price you keep after paying for ingredients. That money has to cover everything else: rent, wages, electricity, water, repairs, taxes and the profit you take home.
A simple way to express it: if ingredient cost represents a small fraction of the selling price (say, a quarter or a third), the rest is your margin. The smaller that fraction, the more margin you keep. The bigger, the less.
There's no single correct figure: it depends on your type of business. A street stall with few fixed costs can work with a tighter margin than a café with high rent in central Dublin. What matters is that the margin covers your real costs and leaves some profit.
Build the selling price with visible arithmetic
Now you build the price. You decide what fraction of the selling price ingredients will represent. Then you work backwards: if ingredient cost is that fraction, what does the total price need to be?
The formula is simple: Selling price = Ingredient cost ÷ Target fraction.
Example (illustrative round numbers):
| Item | Amount (£) | Calculation |
|---|---|---|
| Ingredient cost (omelette) | 2.00 | Sum of all ingredients |
| Target cost fraction | 1/3 | You decide ingredients should be one third of the price |
| Calculated selling price | 6.00 | 2.00 ÷ (1/3) = 2.00 × 3 = 6.00 |
| Gross margin | 4.00 | 6.00 − 2.00 = 4.00 |
That margin has to pay for everything else. If you've got nothing left at the end of the month, you need to raise the price, lower the ingredient cost or sell more dishes.
Common mistakes that cost you money
Forgetting small ingredients. The oil, salt, herbs, sauce. They seem insignificant, but if you use decent olive oil and cook many dishes a day, those litres add up. Write down everything.
Not updating prices when ingredients go up. You bought cheaper potatoes last month. This month they went up. If you don't recalculate, you're selling with a margin that no longer exists. Review costs every time you get an invoice with a different price.
Copying the neighbour's prices. They've got a different supplier, different rent, different recipe. Their price doesn't work for you. Calculate your own.
Adjust the price for real-world context
The arithmetic gives you a minimum price you need to survive. But then you look around: what are people charging for similar dishes in your area? Is your dish bigger, smaller, better, different? Are you on the Cornish coast, in central Manchester or at a neighbourhood market in Cork?
If your calculated price is much higher than what people are willing to pay, you've got three choices: lower ingredient cost (buy cheaper, change the recipe, reduce portion size), raise perceived value (better presentation, local ingredients, clear story) or accept that dish doesn't work and cook something else.
If your calculated price is lower than the market rate, good. Raise it to where the market will bear it and keep the extra margin.
Practical steps you can do today
Pick your best-selling dish. Weigh every ingredient you use and find it on your last invoice. Note the unit cost and multiply. Add it all up. Decide what fraction of the price you want cost to represent (one third is a good starting point for many small businesses). Divide cost by that fraction. That's your minimum price.
Compare it with what you charge now. If you're below, you're giving money away. If you're above, work out how much margin you're keeping and check whether it covers your real monthly expenses.
Repeat the exercise with three or four more dishes. Then you know which ones leave profit and which ones cost you money.
Frequently asked questions
How often should I recalculate the price?
Every time a major ingredient price goes up or when you notice the margin getting too tight. At minimum, review costs every quarter.
Do I include VAT in the selling price?
Depends on your situation. In the UK, most hot food served in a restaurant carries VAT (currently at the standard rate, though some items may be exempt or zero-rated under HMRC rules). In the European Union, VAT on catering varies by country. Always calculate the price excluding VAT first, check it covers your costs and margin, then add VAT according to what you're required to declare.
What if my ingredient cost changes every week?
Use the most recent high price or average the last few invoices. Better to calculate with a slightly inflated cost and keep extra margin than to calculate with an old cost and lose money without realising.
