Over 60% of restaurant failures stem from poor cost control, yet most owners focus solely on revenue. Gross profit - your sales minus direct food and beverage costs - reveals what you actually have left to cover staff, rent, and other expenses. This metric determines if you're building wealth or bleeding money each month.
What exactly is gross profit?
Gross profit shows what remains after you subtract direct product costs from your sales. For restaurants, this means your food and beverage expenses.
💡 Example:
Restaurant De Smaak had last month:
- Revenue: €45,000
- Food costs: €13,500
- Beverage costs: €3,600
Gross profit: €45,000 - €17,100 = €27,900
The formula for gross profit
The math is straightforward:
Gross Profit = Revenue - Cost of Goods Sold (COGS)
For restaurants this breaks down to:
- Revenue: All food and beverage sales (excluding VAT)
- COGS: Purchase costs of ingredients and beverages you actually sold
⚠️ Note:
Always calculate using revenue excluding VAT. VAT collected goes straight to tax authorities - it was never yours to begin with.
Calculate gross profit percentage
The absolute amount matters less than your gross profit percentage. This reveals your true margin:
Gross Profit % = (Gross Profit / Revenue) × 100
💡 Example:
Using the figures from above:
- Gross profit: €27,900
- Revenue: €45,000
Gross profit %: (€27,900 / €45,000) × 100 = 62%
What's a good gross profit for restaurants?
Typical gross profit percentages vary by restaurant type:
- Fine dining: 65-72%
- Casual dining: 65-70%
- Fast casual: 70-75%
- Café with food: 65-70%
Fast casual operations often achieve higher percentages due to lower labor costs and simpler ingredients.
💡 Comparison example:
Two restaurants with €50,000 revenue:
- Restaurant A: 60% gross profit = €30,000 left for fixed costs
- Restaurant B: 70% gross profit = €35,000 left for fixed costs
Restaurant B has €5,000 more room for rent, staff and profit.
Why gross profit matters more than revenue
Many operators obsess over sales figures, but that creates a dangerous blind spot. High revenue with poor gross profit leads straight to bankruptcy.
- Gross profit reveals your actual earning power
- It guides menu optimization decisions
- You'll catch margin erosion before it kills you
- It enables meaningful period-to-period comparisons
This is the kind of thing you only learn after closing your first month at a loss - revenue vanity can cost you everything.
Using gross profit to make smarter decisions
Monthly gross profit tracking reveals critical patterns:
- Declining gross profit: Supplier price increases outpaced your menu adjustments
- Rising gross profit: You've successfully raised prices or found better suppliers
- Seasonal fluctuations: Ingredient costs vary throughout the year
⚠️ Note:
Gross profit doesn't guarantee net profit. You still face staff wages, rent, utilities and other expenses. But without healthy gross profit, there's zero room for actual profit.
Tools to track gross profit
Manual calculations work but consume valuable time. Food cost calculators automatically compute per-dish costs and display daily or monthly gross profit. This gives you instant visibility into your targets.
How do you calculate gross profit? (step by step)
Gather your revenue excl. VAT
Get your POS system or accounting records and note your total revenue for the period you want to calculate. Make sure you use revenue excl. VAT - at 9% VAT divide by 1.09.
Add up all your purchase costs
Collect all invoices from your suppliers for the same period. Add up the costs of all ingredients, beverages and other products you resold directly to guests.
Subtract purchase costs from revenue
Gross profit = Revenue excl. VAT - Total purchase costs. For the percentage: divide gross profit by revenue and multiply by 100. This gives you your gross profit percentage.
✨ Pro tip
Check your gross profit margin within 48 hours of any supplier price increase - inflation can kill your margins before you even notice. Your food costs might look fine on paper while your actual profitability gets destroyed.

Frequently asked questions
What's the difference between gross profit and net profit?
Gross profit is revenue minus direct costs (food/beverage). Net profit subtracts all remaining expenses like staff, rent and utilities from gross profit. Gross profit shows your margin potential, while net profit reveals your actual bottom line.
Should I include VAT in my gross profit calculation?
No, always use revenue excluding VAT. The VAT you collect belongs to tax authorities, not your business. With 9% VAT, divide your till total by 1.09 to get the true revenue figure.
How often should I calculate my gross profit?
Monthly calculations provide the optimal balance of insight and effort. Weekly tracking helps during peak seasons or after price changes. Daily calculations rarely justify the time investment unless you're troubleshooting specific issues.
What if my gross profit percentage drops suddenly?
Check supplier invoices first - they may have raised prices without notice. Examine portion control in your kitchen for oversized servings. Consider menu price adjustments or substitute expensive ingredients with cost-effective alternatives.
Do packaging costs count toward gross profit calculations?
Yes, takeaway containers and delivery packaging are direct costs that must be subtracted from revenue. Like ingredients, packaging costs directly correlate with each sale you make.
How do I handle waste and spoilage in gross profit calculations?
Include all food purchases in your COGS, whether sold or wasted. This gives you true cost visibility and motivates waste reduction. Track waste separately to identify problem areas, but don't exclude it from gross profit calculations.
