Tire shop Growth Funding Gap
Funding gap = extra monthly sales × upfront cost × collection delay − allocated cash
Gather repair orders, parts invoices and technician time logs. Include tires, consumables, and fitting labour. The starting figures are examples. Replace them with your own records.
Formula and worked example
Funding gap = extra monthly sales × upfront cost × collection delay − allocated cash
| Input | Example |
|---|---|
| Additional monthly sales | 30 |
| Upfront cash cost per sale | 200 |
| Months until collection | 2 |
| Cash allocated to growth | 5,000 |
| Calculated result | 7,000 |
Choose reliable inputs
Separate parts, technician time and bay availability for each repair order. For this tire shop calculation, use repair orders, parts invoices and technician time logs and a consistent definition of one service order.
- Tires: include the portion belonging to this service order or reporting period, and record where the value came from.
- Consumables: include the portion belonging to this service order or reporting period, and record where the value came from.
- Fitting labour: include the portion belonging to this service 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 higher sales increase the cash gap?
Yes, when delivery costs are paid before customers settle. More sales can consume more working cash before collections catch up.
Assumes a steady additional volume and identical costs and delays; capacity investment is excluded.
What if this input changes?
If additional monthly sales rises by 10%, this example changes by 1,200 . 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.
