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 days of payments does my cash cover?
This excludes future receipts and uses historical average payments, so it differs from net-burn runway.
What if this input changes?
If available unrestricted cash rises by 10%, this example changes by 6 days. 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.
