Gross margin shows profit after ingredient costs, while net margin reveals what's left after all expenses. Both matter, but the gap between them exposes whether your overhead is killing profits despite good food costs.
Your restaurant could be bleeding money even with perfect ingredient costs. Gross margin shows profit after direct costs like ingredients, while net margin reveals what's left after everything—rent, staff, utilities. Most operators track one but ignore the other, missing where their profits actually disappear.
What is gross margin?
Gross margin is the percentage remaining after you subtract direct costs. For restaurants, that's primarily ingredients and beverages.
💡 Gross margin example:
You sell a pasta for €18.50 (incl. 9% VAT)
- Selling price excl. VAT: €16.97
- Ingredient costs: €5.10
- Gross margin: €16.97 - €5.10 = €11.87
Gross margin %: (€11.87 / €16.97) × 100 = 69.9%
Gross margin formula:
Gross margin % = ((Selling price - Direct costs) / Selling price) × 100
What is net margin?
Net margin reveals what remains after every expense gets paid. Rent, staff wages, insurance, energy bills, depreciation—everything.
💡 Net margin example:
Restaurant with €500,000 annual revenue
- Revenue: €500,000
- Direct costs: €150,000 (30%)
- Fixed costs: €300,000 (60%)
- Net profit: €50,000
Net margin: (€50,000 / €500,000) × 100 = 10%
Net margin formula:
Net margin % = (Net profit / Revenue) × 100
The big difference
The gap between gross and net margin exposes your cost structure. High gross margin paired with low net margin? Your overhead is crushing you.
⚠️ Watch out:
Many owners obsess over gross margin while ignoring fixed costs. You might achieve a gorgeous 70% gross margin, but excessive rent and payroll can still sink your business.
Typical margins in hospitality
Standard restaurant margins for comparison:
- Gross margin: 65-75% (after ingredient costs)
- Net margin: 3-8% (after all expenses)
The difference gets consumed by payroll (25-35% of revenue), rent (6-10%), utilities, insurance, and other overhead expenses. Something most kitchen managers discover too late is that a 2% shift in labor costs can completely eliminate net profit.
How do you use both figures?
Gross margin helps optimize your menu. Dishes with poor gross margins drain your profits. Net margin evaluates your entire operation's health.
💡 Practical example:
Your gross margin hits 70%, but net margin limps at 2%
- Ingredient costs aren't the problem
- Examine payroll, rent, utilities
- Consider price increases
Flip side: modest gross margin (60%) with solid net margin (6%) means you've mastered overhead control.
How do you calculate gross and net margin?
Calculate your gross margin
Subtract your direct costs (ingredients, beverages) from your selling price. Divide the result by your selling price and multiply by 100 for the percentage.
Gather all costs for net margin
Add up all costs: ingredients, staff, rent, energy, insurance, depreciation, marketing. These are your total costs.
Calculate your net margin
Subtract your total costs from your revenue to get your net profit. Divide the net profit by your revenue and multiply by 100 for the percentage.
✨ Pro tip
Track gross margin weekly but net margin monthly—fixed costs change slowly while ingredient costs fluctuate daily. Focus your weekly reviews on the dishes that generate 60% of your revenue.

Frequently asked questions
What is a good gross margin for restaurants?
Standard gross margin runs 65-75%. Below 65% makes covering fixed costs nearly impossible.
Why is my net margin so low despite good gross margin?
Your overhead is probably excessive. Target maximum 35% of revenue for labor and 10% for rent.
Should I calculate margins including or excluding VAT?
Always exclude VAT from margin calculations. VAT belongs to the tax authority, not your profit calculations.
