Pool maintenance Sales Volume for Target Profit
Required volume = ceiling((fixed costs + target profit) / unit contribution)
Gather a completed job sheet, supplier quotes and a crew schedule. Include chemicals, driving time, and seasonal demand. 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 pool visit | 500 |
| Variable cost per pool visit | 300 |
| Calculated result | 60 sales |
Choose reliable inputs
Plan materials, travel and crew time before committing to a price. For this pool maintenance calculation, use a completed job sheet, supplier quotes and a crew schedule and a consistent definition of one pool visit.
- Chemicals: include the portion belonging to this pool visit or reporting period, and record where the value came from.
- Driving time: include the portion belonging to this pool visit or reporting period, and record where the value came from.
- Seasonal demand: include the portion belonging to this pool visit 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.
