Plumbing service Delivery Cost per Stop
Cost per stop = (hours × driver cost + distance × vehicle cost) / stops
Gather a completed job sheet, supplier quotes and a crew schedule. Include fittings, access time, and travel. The starting figures are examples. Replace them with your own records.

Choose reliable inputs
Plan materials, travel and crew time before committing to a price. For this plumbing service calculation, use a completed job sheet, supplier quotes and a crew schedule and a consistent definition of one service visit.
- Fittings: include the portion belonging to this service visit or reporting period, and record where the value came from.
- Access time: include the portion belonging to this service visit or reporting period, and record where the value came from.
- Travel: include the portion belonging to this service visit 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.
Do shorter routes always mean cheaper deliveries?
Compare completed stops and total paid time. Vehicle cost must exclude driver pay to avoid double counting.
What if this input changes?
If paid route hours rises by 10%, this example changes by 0.625 per stop. 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.
