I've watched too many restaurant owners launch gorgeous new menus only to discover months later they're bleeding money on every plate. The excitement of creating new dishes often overshadows the brutal math of food costs. You can't afford to guess what your dishes actually cost.
Why food cost control before launch is crucial
Launching a menu without knowing your costs is financial suicide. You're essentially gambling with every order that comes through your kitchen. Most kitchen managers discover too late that their most popular dishes were the ones draining their profits - sometimes for entire seasons before anyone notices the damage.
⚠️ Watch out:
A dish with 40% food cost that you sell 100 times per week costs you €2,600 extra per year compared to 30% food cost.
Gather all ingredients and current prices
Build a complete ingredient breakdown for each dish. And I mean everything - that pinch of sea salt, the microgreens, the drizzle of truffle oil. Those "small" additions add up fast.
💡 Example: Grilled salmon with vegetables
- Salmon fillet 180g: €5.40
- Vegetable mix 120g: €1.20
- Butter 15g: €0.18
- Spices and oil: €0.35
- Lemon and garnish: €0.42
Total ingredient costs: €7.55
Pull your latest supplier invoices - not the ones from six months ago. Prices shift constantly, especially for proteins and seasonal ingredients. That salmon might've jumped 15% since your last order.
Calculate food cost percentage per dish
Here's where the rubber meets the road. Use this formula: Food cost % = (Ingredient costs / Selling price excl. VAT) × 100
Always work with prices excluding VAT. Your menu shows prices including that 9% food VAT, but your calculations need the real number.
💡 Example calculation:
You sell salmon for €26.50 incl. VAT
- Selling price excl. VAT: €26.50 / 1.09 = €24.31
- Ingredient costs: €7.55
- Food cost: (€7.55 / €24.31) × 100 = 31.1%
That's a healthy food cost for fish.
Check your food cost against benchmarks
Different dishes have different cost tolerances. Don't expect your wagyu steak to hit the same percentages as your pasta primavera.
- Fish and meat: 28-35%
- Pasta and vegetarian: 22-30%
- Salads: 25-32%
- Desserts: 20-28%
- Soups: 18-25%
Exceed these ranges? You're probably hemorrhaging money with every order. Time to make some hard choices about pricing or portions.
⚠️ Watch out:
A food cost of 40% means you only keep €0.60 from every euro in sales for all other costs (staff, rent, energy, profit).
Optimize dishes with too high food cost
Got dishes pushing 40% food cost? You've got three moves:
- Raise selling price: Usually the quickest fix
- Adjust recipe: Swap expensive ingredients or trim portions
- Cut the dish: Sometimes you can't save them all
💡 Example optimization:
Your risotto has 38% food cost at €18.50 selling price
- Option 1: Raise to €21.50 → 28% food cost
- Option 2: Replace expensive cheese with cheaper alternative
- Option 3: Reduce rice portion from 100g to 85g
Test your new prices before launch
Before you send that menu to the printer, run the numbers one final time. Calculate your overall menu food cost average - aim for 28-33% across all dishes.
But also gut-check your pricing logic. Guests notice when your appetizer costs more than your entree. That's a red flag that screams "we don't know what we're doing."
Tools like KitchenNmbrs can automate these calculations and show you exactly which dishes will make money before you commit to printing thousands of menus.
How do you check food cost before menu launch? (step by step)
Create complete ingredient list per dish
Write down all ingredients including garnishes, sauces and spices. Check current purchase prices with your suppliers. Add up everything that goes on the plate.
Calculate food cost percentage per dish
Use the formula: (Ingredient costs / Selling price excl. VAT) × 100. Always calculate excluding VAT - divide your menu price by 1.09.
Compare with benchmarks and optimize
Check if your food cost stays below 35% for most dishes. Adjust prices or optimize recipes for dishes that score too high.

Frequently asked questions
Should I include VAT in my food cost calculation?
Never include VAT in your food cost calculations. Always divide your menu price by 1.09 to get the excluding-VAT price first. Including VAT will make your food costs look artificially low and mess up your entire pricing strategy.
What if my food cost is higher than 35%?
You're losing money on every plate. Either raise your selling price, reformulate the recipe with cheaper ingredients, or cut the dish entirely. There's no magic trick - the math doesn't lie.
How often should I check my food cost?
Monthly at minimum, weekly if you're using volatile ingredients like seafood or seasonal produce. Supplier prices change constantly, and your costs need to reflect reality, not last quarter's invoices.
Can I use different food cost percentages per dish?
Absolutely - and you should. Premium proteins naturally run higher (28-35%) while pasta dishes should hit lower percentages (22-30%). What matters is your weighted average across the entire menu.
What if my competitor sells the same dish cheaper?
Don't assume your competitor is profitable - many restaurants sell below cost without realizing it. Focus on your own margins first. You can't compete if you're bleeding money on every order.
How do I handle seasonal price fluctuations for ingredients?
Build seasonal pricing into your menu strategy from day one. Either use variable pricing throughout the year or price based on peak-season costs to maintain consistent margins.
Should I calculate food cost on the exact portion size or add waste factor?
Always include waste factor in your calculations. Add 3-5% for prep waste, trim loss, and kitchen mistakes. Your theoretical portion cost isn't what you'll actually spend per dish.
