Choose reliable inputs
Plan materials, travel and crew time before committing to a price. For this restoration service calculation, use a completed job sheet, supplier quotes and a crew schedule and a consistent definition of one restoration job.
- Equipment rental: include the portion belonging to this restoration job or reporting period, and record where the value came from.
- Monitoring: include the portion belonging to this restoration job or reporting period, and record where the value came from.
- Crew time: include the portion belonging to this restoration job 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 can I afford to pay for a lead?
A negative ceiling means the required retained contribution already exceeds the sale contribution. Repeat revenue is excluded.
What if this input changes?
If first-sale revenue rises by 10%, this example changes by 20 per qualified lead. 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.
