Calculator Inputs
Enter hotel arrival and revenue assumptions. This calculator uses booked arrivals after cancellations to measure operational and financial no show impact.
Plotly Graph
This chart compares booked arrivals, actual shows, no shows, and revenue protection drivers.
Example Data Table
Use this example to understand how different arrival patterns affect no show rate and financial exposure.
| Scenario | Total Reservations | Cancellations | Effective Booked Arrivals | Checked In Booked | Walk Ins | No Shows | No Show Rate | ADR |
|---|---|---|---|---|---|---|---|---|
| Weekday Business Mix | 140 | 12 | 128 | 118 | 7 | 10 | 7.81% | $145 |
| Weekend Leisure Mix | 180 | 24 | 156 | 147 | 10 | 9 | 5.77% | $172 |
| Event Peak Day | 220 | 10 | 210 | 190 | 16 | 20 | 9.52% | $248 |
Formula Used
Effective Booked Arrivals = Total Reservations − Cancellations
No Shows = Effective Booked Arrivals − Checked In Booked Guests
No Show Rate = (No Shows ÷ Effective Booked Arrivals) × 100
Unfilled Arrivals = No Shows − Walk Ins − Overbooking Buffer
If negative, the result is treated as zero.
Lost Room Nights = Unfilled Arrivals × Average Length of Stay
Gross Lost Revenue = Lost Room Nights × ADR
Estimated Fee Recovery = No Shows × Average Stay × ADR × Fee Recovery % × Collection Success %
Net Profit Impact = (Gross Lost Revenue − Estimated Fee Recovery) − Avoidable Variable Cost

Frequently Asked Questions
1) What is a hotel no show rate?
A hotel no show rate measures how many booked arrivals failed to check in after cancellations were removed. It helps revenue teams forecast demand leakage and set smarter arrival controls.
2) Why are cancellations excluded from the formula?
Cancellations should not count as no shows because the reservation was released before arrival. Excluding them gives a cleaner view of guest behavior and operational forecasting accuracy.
3) Do walk ins reduce the no show rate?
No. Walk ins do not change the no show rate itself. They reduce revenue damage by filling gaps created by missing arrivals, which is why they are included in the financial analysis.
4) Why does this calculator include fee recovery?
Some hotels charge first-night penalties or partial retention fees for missed arrivals. Fee recovery shows how much lost revenue may be clawed back when collection policies actually succeed.
5) What does overbooking buffer mean?
Overbooking buffer represents rooms intentionally sold above expected occupancy to offset predictable no shows. This calculator uses it as a protection layer before counting any arrival gaps as unfilled demand.
6) Why include variable cost per room night?
When a room stays unsold, some service costs are avoided. Including variable cost helps estimate profit impact more realistically instead of focusing only on revenue loss.
7) Can I use this daily, weekly, or monthly?
Yes. The formula works for any period as long as the inputs match the same timeframe. Many hotels track it daily for arrivals and monthly for planning trends.
8) What if checked in booked guests exceed effective booked arrivals?
The calculator automatically limits booked check-ins to effective arrivals. This avoids negative no shows and usually signals input inconsistency or mixed reporting between booked guests and walk ins.
