Most restaurants see wildly different profit margins between lunch and dinner service, yet many owners never bother to measure the gap. While lunch crowds grab quick bites, dinner guests linger over wine and appetizers. Tracking these differences reveals which service actually drives your bottom line.
What is average margin per guest?
Average margin per guest shows the actual profit you pocket from each person after covering food costs and direct expenses. The lunch-dinner split usually comes down to three factors:
- Average check value: dinner guests typically order more
- Beverage sales: more alcohol flows in the evening
- Dish selection: lunch stays simple, dinner gets complex
Gather the right data
You'll need these numbers for each service to get accurate results:
💡 Example data lunch vs. dinner:
Lunch service (past week):
- Number of guests: 240
- Total revenue: €3,600 (incl. VAT)
- Food cost: €1,080
- Beverage sales: €480
Dinner service (past week):
- Number of guests: 180
- Total revenue: €4,500 (incl. VAT)
- Food cost: €1,350
- Beverage sales: €1,200
Calculate the margin per service
Start with total margin for each service, then divide by guest count. Simple math, but the devil's in the details.
Formula: Margin per guest = (Revenue excl. VAT - Food cost - Beverage cost) / Number of guests
💡 Lunch calculation:
- Revenue excl. VAT: €3,600 / 1.09 = €3,303
- Food cost: €1,080
- Beverage cost (estimated 25%): €480 / 1.09 × 0.25 = €110
- Total direct costs: €1,190
- Margin: €3,303 - €1,190 = €2,113
Margin per guest: €2,113 / 240 = €8.80
💡 Dinner calculation:
- Revenue excl. VAT: €4,500 / 1.09 = €4,128
- Food cost: €1,350
- Beverage cost (estimated 22%): €1,200 / 1.21 × 0.22 = €218
- Total direct costs: €1,568
- Margin: €4,128 - €1,568 = €2,560
Margin per guest: €2,560 / 180 = €14.22
⚠️ Note:
Beverages carry 21% VAT for alcohol, 9% for non-alcoholic drinks. Get your beverage cost percentages right - alcohol typically runs 18-25%, soft drinks 30-40%.
Analyze the difference
Here's what most kitchen managers discover too late: that €5.42 gap per guest between dinner and lunch adds up fast over a month. The drivers behind this difference include:
- Higher average check: €25.00 vs €15.00 per person
- More beverage sales: €6.67 vs €2.00 per person
- Different dish selection: pricier ingredients hit the dinner menu
Armed with these insights, you can:
- Boost lunch profitability strategically
- Schedule staff based on actual margins
- Focus marketing spend where it counts
Track this weekly
Run these numbers every week to catch shifting patterns. Bad weather might suddenly make lunch your profit star, or a new dinner menu could change everything.
Tools like KitchenNmbrs automate this tracking, so you'll spot which service performs without the spreadsheet headaches.
How do you calculate average margin per guest per service?
Gather data per service
Record separately for lunch and dinner: number of guests, total revenue, food cost, and beverage sales. Measure over at least a week for reliable figures.
Calculate total margin per service
Subtract all direct costs from revenue (excl. VAT): food cost and beverage cost. Pay attention to different VAT rates for food (9%) and alcohol (21%).
Divide by number of guests
Divide the total margin by the number of guests per service. Now you see exactly how much you earn on average per lunch versus dinner guest.
✨ Pro tip
Track your table turnover rate for each service over the next 30 days. If lunch guests turn tables in 45 minutes versus 90 minutes for dinner, that lower per-guest margin might actually generate more hourly profit through volume.

Frequently asked questions
Should I include labor costs in this calculation?
Start with food and beverage costs for quick comparisons. Once you've got that rhythm down, layer in labor costs for the complete profit picture. Most operators find the food-cost-only version gives them 80% of the insights with 20% of the work.
What if I don't have separate figures per service?
Set up lunch and dinner tracking in your POS system starting today. After just one week, you'll have enough data to run meaningful comparisons.
What's a realistic difference between lunch and dinner margins?
Expect dinner to generate €3-8 more per guest due to higher checks and wine sales. Many successful restaurants treat lunch as volume business and dinner as margin business - both strategies work if you know your numbers.
How can I improve my lunch margin without losing customers?
Focus on beverage upsells like specialty coffee or fresh juices, train servers to suggest appetizers, and audit your lunch pricing against current food costs. Small moves here add up quickly across high lunch volumes.
