Quick answer
Calculating your menu prices before opening can make the difference between profit and loss. Many new restaurants fail because they don't know what their dishes really cost. Proper pricing calculations are essential for survival and profitability.

Calculating your menu prices before opening can make the difference between profit and loss. Many new restaurants fail because they don't know what their dishes really cost. Proper pricing calculations are essential for survival and profitability.

Why calculating is so crucial

Opening a restaurant without calculating your menu prices is like driving with a blindfold on. You don't know where you're going and the chance of a crash is huge.

⚠️ Heads up:

70% of restaurants that close within 2 years had no idea what their dishes really cost. They guessed on their prices.

By calculating your menu prices in advance, you avoid these pitfalls:

  • Prices too low: You're selling every dish at a loss
  • Unrealistic expectations: You think you're making profit, but you're not
  • Cashflow problems: Your money runs out before you know it
  • Wrong focus: You promote dishes that cost you money

The real cost of a dish

Many starting entrepreneurs only think about the main ingredients. But a dish costs much more than that. I've seen this mistake cost the average restaurant EUR 200-400 per month in overlooked ingredient expenses.

? Example: Pasta Carbonara

What you probably calculate:

  • Pasta: €0.80
  • Bacon: €1.20
  • Egg: €0.40
  • Cheese: €0.90

Subtotal: €3.30

What you forget:

  • Olive oil: €0.15
  • Pepper: €0.05
  • Salt: €0.02
  • Garlic: €0.10
  • Parsley: €0.20
  • Butter for pan: €0.08

Real costs: €3.90

That difference of €0.60 seems small, but at 100 portions per week you're spending €3,120 more per year than you thought.

Calculate food cost percentage

The food cost is the percentage of your selling price that goes to ingredients. This is your most important number.

Formula: Food cost % = (Ingredient costs / Selling price excl. VAT) × 100

? Example: Food cost calculation

Your Pasta Carbonara:

  • Ingredient costs: €3.90
  • Menu price: €16.50 (incl. 9% VAT)
  • Price excl. VAT: €16.50 / 1.09 = €15.14

Food cost: (€3.90 / €15.14) × 100 = 25.8%

That's great! Under 30% is good for pasta.

Realistic pricing

If your food cost comes out too high, you have two options: buy ingredients cheaper or raise your price.

⚠️ Heads up:

A food cost above 35% usually means you're losing money on that dish. Your other costs (staff, rent, energy) are then not covered.

Different standards apply to different dishes:

  • Pasta, pizza: 20-28% food cost
  • Meat, fish: 28-35% food cost
  • Salads: 25-32% food cost
  • Desserts: 15-25% food cost

Calculate break-even point

Besides food cost, you need to know how many covers you need at minimum to cover your fixed costs.

? Example: Break-even calculation

Your monthly fixed costs:

  • Rent: €4,000
  • Staff: €8,000
  • Energy: €1,200
  • Insurance: €500
  • Other: €800

Total: €14,500 per month

Average bill: €25 excl. VAT
Average food cost: 30%
Gross margin per guest: €25 × 0.70 = €17.50

Break-even: €14,500 / €17.50 = 829 covers per month

That's about 28 guests per day at 30 days open. Achievable? Then you can start. If not, you need to adjust your concept.

What you need for calculating

To properly calculate your menu prices, you need this information:

  • Exact recipes: All ingredients with quantities
  • Purchase prices: What you really pay per kilo/liter
  • Portion sizes: How many grams/ml per person
  • Trim loss: How much you throw away during preparation
  • Fixed costs: Rent, staff, energy per month

This seems like a lot of work, but it can save you thousands of euros. A food cost calculator helps keep this organized and calculates automatically.

How do you calculate your menu prices? (step by step)

1

Create exact recipes for each dish

Write down exactly which ingredients go into each dish and how much. Don't forget anything: also oil, spices, garnish and everything that goes on the plate. Measure everything in grams or milliliters.

2

Look up all purchase prices

Go to your suppliers and ask for the exact prices per kilo or liter of all ingredients. Also factor in trim loss: if you buy whole fish but serve fillets, it becomes more expensive per kilo of usable product.

3

Calculate the cost price per dish

Add up all ingredient costs for one portion. Divide this by your selling price excluding VAT and multiply by 100 for your food cost percentage. Aim for 25-35% depending on your type of dish.

✨ Pro tip

Calculate your entire opening menu within the first 30 days of planning. You'll discover which dishes work financially before you commit to equipment, suppliers, or marketing materials.

Frequently asked questions

Do I really need to include every ingredient in my calculation?
Yes, absolutely. Even that splash of olive oil or pinch of salt counts. Over a whole year, small ingredients can cost hundreds of euros that you'd otherwise forget.
What's a good food cost for a new restaurant?
For most restaurants, 28-35% is a healthy food cost. Pasta and pizza can be lower (20-28%), meat and fish can be higher (up to 35%). Above 35% becomes difficult to be profitable.
How do I handle seasonal price fluctuations in ingredients?
Build in a 5-10% buffer for price increases and review your costs monthly during peak season changes. Consider seasonal menu adjustments to maintain your target food cost percentages.
