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.
What changes when lead quality falls?
A lower close rate requires more leads for the same customer target and raises the acquisition budget.
Cost per lead and conversion rate are entered assumptions, not auction-price forecasts.
What if this input changes?
If target new customers rises by 10%, this example changes by 450 . 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.
