Auto repair Funnel Sales Forecast
Sales = visits × enquiry rate × qualified share × close rate
Gather repair orders, parts invoices and technician time logs. Include parts, technician time, and shop overhead. The starting figures are examples. Replace them with your own records.
Formula and worked example
Sales = visits × enquiry rate × qualified share × close rate
| Input | Example |
|---|---|
| Relevant visits | 5,000 |
| Visit-to-enquiry rate | 3 % |
| Qualified share of enquiries | 60 % |
| Qualified lead close rate | 25 % |
| Calculated result | 22.5 expected sales |
Choose reliable inputs
Separate parts, technician time and bay availability for each repair order. For this auto repair calculation, use repair orders, parts invoices and technician time logs and a consistent definition of one repair order.
- Parts: include the portion belonging to this repair order or reporting period, and record where the value came from.
- Technician time: include the portion belonging to this repair order or reporting period, and record where the value came from.
- Shop overhead: include the portion belonging to this repair order 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 I multiply rates from different customer cohorts?
Only combine aligned cohorts and time windows. Mixing unrelated stages can create a misleading forecast.
Fractional expected sales are averages, not guaranteed individual outcomes.
What if this input changes?
If relevant visits rises by 10%, this example changes by 2.25 expected 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.
