Auto detailing Monthly Delivery Capacity
Capacity = staff × hours × utilization / hours per sale
Gather repair orders, parts invoices and technician time logs. Include consumables, technician hours, and bay occupancy. The starting figures are examples. Replace them with your own records.
Formula and worked example
Capacity = staff × hours × utilization / hours per sale
| Input | Example |
|---|---|
| Delivery staff | 4 |
| Available hours per staff member | 160 |
| Billable utilization | 65 % |
| Hours per detail package | 8 |
| Calculated result | 52 sales per month |
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.
Why is headcount alone not enough to predict capacity?
Availability, nonbillable time, and hours required per sale determine the delivery throughput.
Assumes interchangeable skills and a stable average job duration.
What if this input changes?
If delivery staff rises by 10%, this example changes by 5.2 sales per month. 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.
