Managing restaurant reservations is like playing chess with invisible pieces. No-show percentage reveals how many reserved guests don't show up, helping you adjust your reservation policy and limit revenue loss. An average no-show rate of 5-15% is normal, but anything higher means you're losing too much potential revenue.
What is no-show percentage?
No-show percentage is the number of reserved guests who don't show up, divided by the total number of reservations. It gives you insight into how reliable your reservations are and helps you make overbooking decisions.
Formula:
No-show % = (Number of no-shows / Total number of reservations) × 100
💡 Example:
Last month you had:
- 120 reservations
- 18 no-shows
No-show percentage: (18 / 120) × 100 = 15%
Why no-show percentage matters
A high no-show percentage costs you money directly. Every empty table that was reserved could've generated revenue. At 15% no-show, you're potentially losing 15% of your reserved revenue.
- Revenue loss: Empty tables generate no income
- Labor costs: You've scheduled staff for more guests
- Purchasing: You may have ordered too many ingredients
- Opportunity costs: You've turned away other guests
💡 Example:
Restaurant with 40 seats, average check €35:
- 10% no-show = 4 empty seats per evening
- Revenue loss per evening: 4 × €35 = €140
- Per month (25 days): €140 × 25 = €3,500
Annual revenue loss: €42,000
Benchmarks by restaurant type
No-show percentages vary by type of establishment and reservation policy:
- Fine dining: 5-10% (guests plan more carefully)
- Casual dining: 10-15% (less commitment)
- Bistro/brasserie: 8-12% (mix of spontaneous and planned)
- Special occasions: 15-25% (weather/circumstances dependent)
⚠️ Note:
Above 15% no-show is problematic. You're losing too much potential revenue and need to take action.
Using no-show percentage for reservation strategy
With your no-show data, you can make smarter decisions:
1. Calculate overbooking
If you historically have 10% no-show, you can overbook by 10%. With 40 seats, you'd accept 44 reservations. But this is the kind of thing you only learn after closing your first month at a loss – start conservatively.
💡 Overbooking example:
40 seats, 12% average no-show:
- Overbooking: 40 × 1.12 = 45 reservations
- Expected occupancy: 45 × 88% = 40 guests
Risk: if everyone shows up, you have 5 extra guests.
2. Adjust confirmation policy
High no-show percentage? Implement a confirmation policy:
- Call guests the day before
- Send confirmation SMS
- Request credit card guarantee
- Implement cancellation fee
3. Time slot-specific strategy
Analyze no-show by time slot. You'll often see patterns:
- Early slots (5:30-6:30 PM): Lower no-show
- Prime time (7:00-8:30 PM): Average no-show
- Late slots (9:30 PM+): Higher no-show
Reducing no-show percentage
Concrete actions to reduce no-shows:
- Request confirmation: SMS or email the day before
- Reservation terms: Clear cancellation policy
- Credit card guarantee: For groups of 6 or more
- Waitlist management: Call waitlist if you get no-shows
- Flexible policy: Easy rescheduling encourages honest communication
⚠️ Note:
Too strict a policy can scare away guests. Find a balance between no-show prevention and hospitality.
Collecting no-show data
To use no-show percentage as a KPI, you need to collect data systematically:
- Record every reservation with date/time
- Note which guests don't show up
- Distinguish between no-shows and last-minute cancellations
- Track by day of week and time slot
- Keep at least 6 months of data for trends
Many restaurants use their reservation system for this, but you can also track it manually in a food cost calculator like KitchenNmbrs under 'Daily checks'.
How do you calculate and use no-show percentage? (step by step)
Collect reservation data
Record all reservations from the past month: date, time, number of people, and whether they actually showed up. Distinguish between no-shows (didn't come, didn't call) and cancellations.
Calculate your no-show percentage
Divide the number of no-shows by the total number of reservations and multiply by 100. For example: 15 no-shows out of 100 reservations = 15% no-show rate.
Analyze patterns by time slot
Check if certain time slots, days, or seasons have higher no-show percentages. This helps you take targeted measures.
Set your overbooking strategy
If you consistently have 10% no-show, you can overbook by 10%. Start cautiously with 5% overbooking and build up gradually.
Monitor and adjust monthly
Check your no-show percentage every month and adjust your strategy. Seasons, weather, and events can affect your numbers.
✨ Pro tip
Track your no-show percentage by day of the week over 8 weeks minimum. Friday and Saturday often have lower no-show rates because guests plan more carefully, while weekdays can spike up to 20%.

Frequently asked questions
What is an acceptable no-show percentage?
For most restaurants, 5-15% is normal. Fine dining is often lower (5-10%), casual dining higher (10-15%). Above 15%, you need to take action.
Can I overbook if I have no-shows?
Yes, overbooking is allowed as long as you're transparent. Start cautiously with 5-10% overbooking and build experience. Always have a backup plan: quick alternative tables, contacts at other restaurants, or compensation for guests who have to wait.
Should I count no-shows differently than cancellations?
Yes, only count true no-shows (didn't come without notice). Timely cancellations aren't no-shows, even though they cost revenue. This distinction is crucial for accurate tracking and strategy development.
