Expected contribution is a ceiling before overhead and desired profit, not a recommended bid. Averages can hide low-quality leads.
Try this with your own numbersFormula and worked example
Lead value = close rate × (sale revenue − variable cost)
| Input | Example |
|---|---|
| Lead-to-sale rate | 20 % |
| Average first detail package revenue | 1,000 |
| Variable first-sale cost | 650 |
| Calculated result | 70 per lead |
Choose reliable inputs
Separate parts, technician time and bay availability for each repair order. For this auto detailing calculation, use repair orders, parts invoices and technician time logs and a consistent definition of one detail package.
- Consumables: include the portion belonging to this detail package or reporting period, and record where the value came from.
- Technician hours: include the portion belonging to this detail package or reporting period, and record where the value came from.
- Bay occupancy: include the portion belonging to this detail package 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 much can I afford to pay for a lead?
Expected contribution is a ceiling before overhead and desired profit, not a recommended bid. Averages can hide low-quality leads.
Excludes repeat purchases, fixed costs, and acquisition spend.
What if this input changes?
If lead-to-sale rate rises by 10%, this example changes by 7 per 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.
