I'll admit something most restaurant owners won't - I used to think revenue was everything. But GOP (Gross Operating Profit) changed my perspective completely. It reveals what your restaurant actually earns from daily operations, stripping away the noise to show real profitability.
What exactly is GOP?
GOP stands for Gross Operating Profit. It's your revenue minus all operational costs (food, staff, rent, energy), but before interest and depreciation. GOP gives you the clearest picture of how your restaurant's core operations perform.
💡 Example:
Restaurant with €45,000 revenue in March:
- Revenue: €45,000
- Food cost: €13,500 (30%)
- Staff costs: €15,750 (35%)
- Rent: €4,500
- Energy & other: €3,600
GOP: €45,000 - €37,350 = €7,650 (17%)
The GOP formula
GOP = Revenue - (Food cost + Staff costs + Rent + Energy + Other operational costs)
Every cost directly tied to running your restaurant gets subtracted from revenue. What remains is your GOP - the money your operations actually generate.
⚠️ Note:
Interest on loans and depreciation on equipment aren't part of GOP calculations. Those expenses come later.
Which costs do you include?
For accurate GOP calculations, capture every operational expense:
- Food cost: All ingredients and beverages
- Staff costs: Wages, social contributions, temporary staff
- Rent: Premises, possibly equipment lease
- Energy: Gas, water, electricity
- Other: Cleaning, insurance, maintenance, marketing
Calculate GOP percentage
GOP % = (GOP / Revenue) × 100
The percentage reveals your actual profit margin. Healthy GOP ranges from 15-25% for most restaurants. Anything below 10% signals trouble ahead.
💡 Calculation example:
Bistro with monthly revenue €38,000:
- Food cost: €11,400 (30%)
- Staff: €13,300 (35%)
- Rent: €3,800
- Energy: €1,900
- Other: €2,280
GOP: €38,000 - €32,680 = €5,320
GOP%: (€5,320 / €38,000) × 100 = 14%
Compare GOP with previous months
GOP's real value emerges through monthly comparisons. Track your GOP every month and analyze the trends. Rising or falling percentages? Find the root cause.
- Lower GOP: costs increased or revenue dropped?
- Higher GOP: what changes drove improvement?
- Seasonal patterns: which months consistently underperform or excel?
This pattern we see repeatedly in restaurant financials - owners who track GOP monthly make faster adjustments and maintain healthier margins than those who don't.
⚠️ Note:
High revenue with low GOP creates more risk than moderate revenue with healthy GOP. Focus on percentage, not just dollar amounts.
Improve your GOP
Low GOP? You've got three paths forward:
- Boost revenue: More guests, higher average bill
- Cut food costs: Smarter purchasing, reduced waste
- Trim other expenses: Efficient scheduling, energy conservation
Food costs often offer the quickest wins. Dropping 3 percentage points (from 33% to 30%) instantly adds 3% to your GOP.
💡 Impact example:
Restaurant with €40,000 monthly revenue:
- Food cost from 33% to 30% = €1,200 savings
- GOP rises from €6,000 to €7,200
- GOP% rises from 15% to 18%
Annual impact: €14,400 extra profit
GOP vs EBITDA
GOP and EBITDA appear similar but serve different purposes. EBITDA follows official financial standards, while GOP functions as a practical hospitality metric. For day-to-day restaurant management, GOP delivers more actionable insights.
How do you calculate GOP step by step?
Gather your monthly revenue
Get your POS system or administration and note the total revenue for the month. Add up all sales, including beverages and any extras.
Sum all operational costs
Add food cost, staff costs, rent, energy and other costs together. Leave out interest and depreciation - those don't belong in GOP.
Subtract costs from revenue
GOP = Revenue minus all operational costs. The result is your Gross Operating Profit in euros for that month.
Calculate the GOP percentage
Divide your GOP by your revenue and multiply by 100. You can compare this percentage with other months and benchmarks.
✨ Pro tip
Track your GOP weekly rather than monthly for faster problem detection. Calculate it every Tuesday morning using the previous week's data - this 7-day rhythm catches issues before they compound into bigger losses.

Frequently asked questions
What is a healthy GOP for a restaurant?
Healthy GOP typically ranges from 15-25% for most restaurants. Anything below 10% signals serious sustainability issues, while above 25% indicates excellent performance.
Should I include VAT in my GOP calculation?
Never include VAT in GOP calculations. Both revenue and costs should exclude VAT to ensure accurate results. Including VAT distorts your true operational performance.
What if my GOP is negative?
Negative GOP means you're losing money on core operations - an unsustainable situation. Immediately analyze where costs exceed reasonable levels or revenue falls short. Swift action prevents deeper financial problems.
