Revenue per available seat per hour reveals the brutal truth about restaurant efficiency that most owners ignore. This metric cuts through vanity numbers to show exactly how much money each seat generates during operating hours. You'll spot profit leaks during slow periods faster than any other calculation.
What is revenue per available seat per hour?
This KPI measures euros earned per seat during each hour you're open. It reveals capacity utilization better than total sales figures alone.
Formula: Revenue per seat per hour = Total revenue / (Number of seats × Number of opening hours)
💡 Example:
Restaurant with 40 seats, open 8 hours per day, revenue €2,400 per day:
- Total revenue: €2,400
- Number of seats: 40
- Opening hours: 8 hours
€2,400 / (40 × 8) = €7.50 per seat per hour
Why this KPI matters
Total revenue tells you nothing about efficiency. A packed restaurant earning €5 per seat hourly underperforms a half-empty place generating €12 per seat.
- Identify your slowest periods instantly
- Compare performance across different shifts
- Make data-driven decisions about operating hours
- Evaluate expansion opportunities accurately
Benchmarks for different restaurant types
Revenue per seat hourly varies dramatically by concept and positioning:
- Fine dining: €15-25 per seat per hour
- Casual dining: €8-15 per seat per hour
- Bistro/brasserie: €6-12 per seat per hour
- Fast casual: €4-8 per seat per hour
⚠️ Note:
These figures serve as guidelines only. Your location, menu pricing, and service style determine realistic targets for your operation.
How to improve this KPI
Low revenue per seat hourly? You've got several levers to pull:
- Boost average check size: Train staff on upselling, add premium options
- Speed up table turns: Streamline service, optimize kitchen workflow
- Fill more seats: Targeted marketing, reservation system optimization
- Cut unprofitable hours: Close during consistently slow periods
💡 Improvement example:
Restaurant increases average check from €30 to €35 per guest:
- Was: €7.50 per seat per hour
- Becomes: €8.75 per seat per hour
- Difference: +€1.25 per seat per hour
With 40 seats, 8 hours per day = €400 extra revenue per day
Analyze different time slots
Don't measure just daily totals - break down performance by time periods. This exposes your most and least profitable hours:
- Lunch (12:00-15:00): Typically generates lower per-seat revenue
- Happy hour (17:00-19:00): Can produce surprisingly high returns
- Dinner (19:00-22:00): Usually your strongest earning window
- Late evening (22:00+): Often drinks-focused with reduced revenue
💡 Practical example of time slots:
Bistro analyzes per time slot:
- Lunch: €4.50 per seat per hour
- Happy hour: €12.00 per seat per hour
- Dinner: €15.00 per seat per hour
Conclusion: Focus marketing on happy hour and dinner service, evaluate lunch profitability.
Understanding hourly seat revenue represents one of the most common blind spots in kitchen management - operators track daily sales but miss the granular insights that drive real profitability improvements. And that's exactly where money gets left on tables, literally.
Tools for revenue tracking
Modern restaurant management systems can automatically calculate seat-hour revenue without manual spreadsheet work. These platforms track sales data and generate reports showing which days and time periods deliver the strongest performance, saving hours of number-crunching.
How do you calculate revenue per seat per hour? (step by step)
Count your available seats
Count all seats in your restaurant where guests can sit. Don't count bar stools or waiting areas, only actual dining seats.
Determine your opening hours per day
Note how many hours your restaurant is open. From first guest to last guest. If you want to measure lunch and dinner separately, split your opening hours.
Calculate your total 'seat-hours'
Multiply number of seats × opening hours. This gives you total capacity. For example: 40 seats × 8 hours = 320 seat-hours per day.
Divide your revenue by seat-hours
Take your total revenue and divide by the number of seat-hours. This gives you revenue per available seat per hour. Use revenue excluding VAT for an accurate picture.
✨ Pro tip
Track your revenue per seat during your busiest 3-hour dinner window separately from daily averages. Most restaurants see 40-60% higher hourly rates during peak service, revealing your true earning potential.

Frequently asked questions
Should I use revenue including or excluding VAT?
Use revenue excluding VAT for accurate performance measurement. VAT belongs to the tax authority, not your actual earnings. This gives you a cleaner picture of what you're really generating per seat.
What if I have different prices for lunch and dinner?
Calculate separate KPIs for each service period. Lunch and dinner operate as distinct businesses with different cost structures and customer expectations. You'll spot which daypart needs attention and where opportunities exist.
Do terraces and outdoor seating count too?
Yes, include all revenue-generating seats in your calculation. Seasonal seating like terraces should be counted during months they're operational. Just track them separately if weather significantly impacts availability.
How often should I measure this?
Weekly measurements provide the sweet spot between actionable insights and trend analysis. Daily numbers fluctuate too much, while monthly reviews miss opportunities for quick corrections.
