Track food costs religiously, focus on your top 5 sellers first, and remember that small improvements compound into massive annual profit gains.
Running a restaurant without tracking menu profitability is like driving blindfolded through rush hour traffic. You might survive for a while, but eventually you'll crash. Most restaurant owners can tell you their busiest dishes but have no clue which ones actually make money.
Check your food cost per dish
Food cost shows you what percentage of each sale goes straight to ingredients. It's your profit compass.
💡 Example:
You sell a risotto for €22.50 incl. 9% VAT:
- Selling price excl. VAT: €20.64
- Ingredient costs: €7.20
- Food cost: (€7.20 / €20.64) × 100 = 34.9%
That's bleeding money for a risotto.
Food cost formula: (Ingredient costs / Selling price excl. VAT) × 100
⚠️ Note:
Always calculate with the price excluding VAT. Your menu shows prices with 9% VAT included. Divide by 1.09 to get the real selling price.
Analyze your profit margins
Food cost tells part of the story. But you need the full picture to avoid nasty surprises.
Gross margin: What's left after paying for ingredients
Net margin: What actually hits your bank account after all expenses
💡 Example:
Steak for €32.00 incl. VAT (€29.36 excl.):
- Ingredient costs: €10.50
- Gross margin: €18.86
- Food cost: 35.8%
- Other costs (70% of revenue): €20.55
Net result: €18.86 - €20.55 = -€1.69 LOSS per steak!
Identify your best-selling dishes
Start with your top 5 sellers. These dishes control most of your profit destiny. Based on real restaurant P&L data, fixing just these five can turn a struggling restaurant profitable.
- Which dishes fly out of your kitchen daily?
- What's each dish actually costing you?
- How much profit does each portion generate?
- Which dishes contribute the most to your monthly profit?
Benchmark your food cost percentages
Here's what sustainable restaurants typically hit:
- Meat/fish dishes: 28-35%
- Pasta dishes: 20-28%
- Salads: 25-32%
- Desserts: 15-25%
- Appetizers: 20-30%
⚠️ Note:
These ranges work for most restaurants, but your numbers might differ based on location, concept, or customer expectations.
Calculate the annual impact
Small food cost improvements create massive yearly gains. The math is beautiful once you see it.
💡 Example:
You serve 50 steaks weekly:
- Current food cost: 38%
- Target: 32%
- Improvement: 6 percentage points on €29.36 = €1.76 per steak
- Annual impact: €1.76 × 50 × 52 = €4,576 extra profit

Digital vs. manual tracking
Excel looks free but costs you hours every week. Plus, one wrong formula can hide profit leaks for months.
Digital systems deliver:
- Automatic calculations (zero math mistakes)
- Real-time profit visibility
- Alerts before food costs spiral
- Trend data to spot problems early
How do you check if your menu generates enough profit?
Calculate the food cost of your top dishes
Take your 5 best-selling dishes. Add up all ingredient costs (including garnish, sauce, oil). Divide by selling price excl. VAT and multiply by 100 for the percentage.
Compare with healthy benchmarks
Check if your food cost falls within normal ranges: meat/fish 28-35%, pasta 20-28%, salads 25-32%. Dishes above these percentages are probably costing you money.
Calculate the gross margin per dish
Subtract ingredient costs from selling price excl. VAT. This is what's left for all other costs (staff, rent, energy). A minimum of €8-12 per main course is healthy.
Analyze total profit per dish
Multiply gross margin by number of sales per week. Dishes with low margin but high sales can still be profitable through volume.
Optimize or replace loss-makers
Dishes with food cost above 35% and low sales figures are loss-makers. Adjust the recipe, raise the price, or replace with a more profitable alternative.
✨ Pro tip
Run a 'profit autopsy' every quarter: pick your 3 lowest-performing dishes and either fix them or kill them. Dead dishes are stealing money from your winners.

Frequently asked questions
What is a healthy food cost for restaurants?
Most profitable restaurants keep food costs between 28% and 35%. Pasta runs lower at 20-28%, while premium meat dishes can hit 35% and still work.
Should I include VAT in my food cost calculation?
Never include VAT in your calculations. Always use the selling price excluding VAT. Divide your menu price by 1.09 to get the correct base number.
How often should I check my food cost?
Check your top-selling dishes monthly at minimum. With volatile ingredient prices, weekly checks prevent nasty surprises. Many successful owners do this every week.
What if my food cost exceeds 40%?
You're losing money on every sale. Fix it by adjusting portions, switching ingredients, or raising prices. Don't wait - high food costs kill restaurants fast.
Do small ingredients like herbs and spices matter?
Absolutely. Those "cheap" garnishes, oils, and seasonings add up to 3-5% of your food cost. Track everything or you'll have mysterious profit leaks.
Can seasonal ingredients mess up my food cost tracking?
Yes, seasonal price swings can destroy your margins if you're not watching. Update your costs monthly during high-volatility seasons like winter for vegetables.
