Event rental Sales Volume for Target Profit
Required volume = ceiling((fixed costs + target profit) / unit contribution)
Gather rental contracts, asset records and maintenance logs. Include transport, setup, and cleaning. The starting figures are examples. Replace them with your own records.
Formula and worked example
Required volume = ceiling((fixed costs + target profit) / unit contribution)
| Input | Example |
|---|---|
| Period fixed costs | 8,000 |
| Target operating profit | 4,000 |
| Revenue per rental booking | 500 |
| Variable cost per rental booking | 300 |
| Calculated result | 60 sales |
Choose reliable inputs
Account for turnaround, maintenance and available inventory before accepting another booking. For this event rental calculation, use rental contracts, asset records and maintenance logs and a consistent definition of one rental booking.
- Transport: include the portion belonging to this rental booking or reporting period, and record where the value came from.
- Setup: include the portion belonging to this rental booking or reporting period, and record where the value came from.
- Cleaning: include the portion belonging to this rental booking or reporting period, and record where the value came from.
Use the same currency for every money input. Do not mix weekly costs with monthly revenue, or count the same expense in both an itemised cost and allocated overhead.
How many sales are needed beyond break-even?
The unit contribution must be positive. Check whether delivery capacity can support the resulting volume.
What if this input changes?
If period fixed costs rises by 10%, this example changes by 4 sales. This shows the effect of one change; it does not predict what will happen.
Open the calculator, save your baseline, then change the input supported by the least reliable estimate in your records. Compare both scenarios before committing to a price or capacity promise.
