Revenue shows how busy you are, margin shows how profitable you are. Many restaurant owners chase big sales numbers while their actual earnings stay flat—focus on what you keep, not just what you earn.
A packed Friday night brings in €3,200, but your bank account barely budges by Monday morning. Revenue shows how busy you were, margin reveals how much you actually earned. Most restaurant owners chase the wrong number and wonder why they're always broke despite being 'successful'.
What is revenue?
Revenue is every euro that comes through your till. Food sales, drinks, service charges—everything your customers pay, VAT included.
💡 Revenue example:
Your restaurant serves 50 guests on Tuesday:
- Average spend per guest: €32.00
- Total revenue: 50 × €32.00 = €1,600
That's your revenue for the shift.
But revenue tells you nothing about profit. You could hit €10,000 in sales and still lose money if your costs eat up €11,000.
What is margin?
Margin is what remains after you pay for everything. Different margins tell different stories:
- Gross margin: Revenue minus direct costs (food, drinks)
- Net margin: Revenue minus everything (staff, rent, utilities)
- Dish margin: Menu price minus ingredient cost
💡 Margin calculation example:
Same Tuesday with €1,600 revenue:
- Food costs: €480 (30% food cost)
- Drink costs: €160 (10% beverage cost)
- Gross margin: €1,600 - €640 = €960
Gross margin percentage: €960 / €1,600 × 100 = 60%
The difference in practice
Too many operators get excited about big revenue nights. "We smashed it—€2,500 in sales!" But if your ingredients cost €900, you've only got €1,600 left to cover wages, rent, and everything else.
This is the kind of thing you only learn after closing your first month at a loss despite record sales figures.
⚠️ Reality check:
Massive revenue with thin margins means you're running a very expensive hobby. Better to serve fewer covers with healthy margins.
Which number matters more?
Both matter, but margin decides if you'll still be open next year. You can't chase revenue forever if it's not translating to actual profit.
- Revenue: Measures your popularity
- Margin: Measures your profitability
- Together: They show the full picture
💡 Tale of two restaurants:
Restaurant A: €8,000 revenue, 25% net margin = €2,000 profit
Restaurant B: €12,000 revenue, 10% net margin = €1,200 profit
Restaurant A makes more money with lower sales.
How do you improve your margin?
Several levers can boost your margins:
- Negotiate better supplier prices
- Standardise portion weights
- Strategic menu price adjustments
- Cut food waste ruthlessly
- Push high-margin dishes through staff training
Track your numbers consistently. Know which dishes make you money and which ones just make you busy.
How do you calculate revenue and margin? (step by step)
Calculate your total revenue
Add all sales from a period together, including VAT. This is your gross revenue. Use your POS system or manually add up all receipts.
Subtract direct costs for gross margin
Subtract ingredient costs and beverage costs from your revenue. Formula: Gross margin = Revenue - Food cost - Drink cost. This gives you gross margin in euros.
Calculate margin percentage
Divide your margin by revenue and multiply by 100. Formula: Margin % = (Margin / Revenue) × 100. You can compare this percentage with other periods.
✨ Pro tip
Track your margin per seat hour, not just per service. A Tuesday lunch with 20% fewer covers but 8% higher margins often generates more profit per hour than your packed Friday nights.

Frequently asked questions
What's considered a healthy margin for restaurants?
Aim for 60-70% gross margin and 15-25% net margin. Fine dining can push higher margins, while fast-casual operations often run leaner. Location and concept heavily influence these numbers.
Should VAT be included in margin calculations?
Include VAT in your revenue figures since that's what customers actually pay. For cost calculations and dish margins, work excluding VAT—that money belongs to the tax office anyway.
Can I boost margins without raising menu prices?
Absolutely. Focus on supplier negotiations, portion control, waste reduction, and promoting your most profitable dishes. Sometimes a 50g reduction in protein portions can add 3-4% to your gross margin.
Why am I busy but still losing money?
High volume with low margins is a classic trap. You're probably underpricing dishes, over-portioning, or focusing on low-margin items that keep you busy but broke.
How frequently should I monitor my margins?
Check gross margins weekly and net margins monthly. Any sudden drops need immediate investigation—they usually signal portion creep, waste issues, or supplier price increases.
What's the biggest margin killer most restaurants miss?
Inconsistent portioning by kitchen staff. A chef who's generous with expensive ingredients can destroy your food cost without you realising until month-end. Standardised recipes and regular portion checks are essential.
