Bicycle repair Sales Volume for Target Profit
Required volume = ceiling((fixed costs + target profit) / unit contribution)
Gather repair orders, parts invoices and technician time logs. Include parts, workshop time, and collection handling. The starting figures are examples. Replace them with your own records.
Formula and worked example
Required volume = ceiling((fixed costs + target profit) / unit contribution)
| Input | Example |
|---|---|
| Period fixed costs | 8,000 |
| Target operating profit | 4,000 |
| Revenue per repair order | 500 |
| Variable cost per repair order | 300 |
| Calculated result | 60 sales |
Choose reliable inputs
Separate parts, technician time and bay availability for each repair order. For this bicycle 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.
- Workshop time: include the portion belonging to this repair order or reporting period, and record where the value came from.
- Collection handling: 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.
How many sales are needed beyond break-even?
The unit contribution must be positive. Check whether delivery capacity can support the resulting volume.
What if this input changes?
If period fixed costs rises by 10%, this example changes by 4 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.
