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.

Can repair upsells rescue an underpriced plan?

Treat uncertain upsells separately. First test whether the committed included service covers its own costs.

Excludes optional repair upsells and fixed business costs unless included explicitly.

Compare a different assumption

What if this input changes?

If annual plan price rises by 10%, this example changes by 36 per member per year. 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.
