Think of your restaurant like a theater where each seat has earning potential. The average spend per guest shows exactly how much value each customer brings to your business. Most restaurant owners focus only on total revenue, missing crucial opportunities to maximize what each guest spends.
What is the average spend per guest?
The average spend per guest (also called 'average spend per head') equals your total revenue divided by the number of guests. This metric reveals the true value each customer brings through your doors.
Formula:
Average spend per guest = Total revenue / Number of guests
💡 Example:
Yesterday in your restaurant:
- Total revenue: €2,400
- Number of guests: 80
Average spend per guest: €2,400 / 80 = €30.00 per guest
Why this number drives your success
Your average spend per guest reveals more than just money coming in. It shows:
- Efficiency: Are you earning enough per guest to stay profitable?
- Trends: Are guests ordering more expensive items or cutting back?
- Performance: How do you stack up against last month or last year?
- Capacity planning: Can you hit revenue targets with fewer covers?
⚠️ Note:
Only count paying guests. Children under 3 who eat for free don't count, but children with a kids menu do.
Benchmarks by restaurant type
From analyzing actual purchasing data across different restaurant types, the average spend varies dramatically by concept:
- Fast casual: €12-18 per guest
- Bistro/brasserie: €25-35 per guest
- Casual dining: €30-45 per guest
- Fine dining: €65-120+ per guest
- Lunch restaurants: €15-25 per guest
These numbers include beverages. Without drinks, expect 20-30% lower averages.
💡 Comparison example:
Two bistros with identical revenue:
- Bistro A: €3,000 revenue, 120 guests = €25 per guest
- Bistro B: €3,000 revenue, 85 guests = €35 per guest
Bistro B runs more efficiently: less kitchen chaos, lower staff costs, same revenue.
Daily vs. weekly calculation
Track your average spend per guest at multiple levels:
Daily: Reveals daily patterns. Monday's usually lower than Saturday.
Weekly: Shows real trends and smooths out slow/busy day variations.
Monthly: Perfect for comparing against previous periods.
How to boost your average spend per guest?
- Upselling: Suggest appetizers, sides, desserts
- Beverage pairing: Recommend wine with specific dishes
- Menu engineering: Position high-margin items prominently
- Daily specials: Feature premium options
- Portion choices: Offer small/large alternatives
💡 Impact of a €2 increase:
If your average spend per guest jumps from €28 to €30:
- 80 guests per day = €160 extra daily
- 6 days per week = €960 extra weekly
- 52 weeks = €49,920 extra annually
Small increase, massive yearly impact.
Digital help with tracking
Modern POS systems calculate this automatically. If you don't have an integrated system, you can track it manually in Excel or specialized apps.
The benefits of digital tracking:
- Automatic calculation
- Comparison with previous periods
- Trends by day of the week
- Easy sharing with your team
How to calculate the average spend per guest? (step by step)
Gather your daily figures
Note the total revenue from yesterday (including VAT) and count the exact number of paying guests. Use your POS system or manually count your receipts.
Apply the formula
Divide your total revenue by the number of guests. For example: €2,400 revenue / 80 guests = €30.00 average spend per guest.
Compare and analyze
Compare with the same day last week or last month. Is it higher or lower? Look for patterns: which days perform better and why?
✨ Pro tip
Track your average spend by 2-week periods instead of monthly. You'll catch trends faster and can adjust your upselling strategy within 14 days rather than waiting a full month to see results.

Frequently asked questions
Do I count children as separate guests?
Yes, if they order a kids menu they count. Children who eat for free (often under 3 years old) don't count toward the number of guests.
Should I include VAT in the calculation?
For the average spend per guest, you use the price including VAT, as the guest pays it. For cost price calculations, you calculate excluding VAT.
What is a good average spend per guest for my type of restaurant?
That depends on your concept. Fast casual runs around €12-18, bistros around €25-35, and fine dining from €65. Most importantly, compare yourself to last month.
How often should I calculate this?
Daily for operational management, weekly for trends, and monthly for comparison with previous periods. Daily fluctuations are completely normal.
What if my average spend per guest is declining?
Analyze the root cause: are more lunch guests coming and fewer dinner guests? Are people ordering fewer drinks? Adjust your offering or service based on these insights.
Should I track this separately for lunch and dinner service?
Absolutely. Lunch typically runs 30-40% lower than dinner service. Tracking separately helps you understand each service's performance and set realistic targets.
How do group bookings affect this calculation?
Large groups often have lower per-person spends due to shared dishes or set menus. Track group bookings separately or note their impact on your daily averages.
