Local delivery Rework Cost Exposure
Rework cost = sales × rework rate × (hours × labour cost + extra materials)
Gather completed route logs, fuel receipts and delivery records. Include driver hours, vehicle cost, and route density. The starting figures are examples. Replace them with your own records.
Formula and worked example
Rework cost = sales × rework rate × (hours × labour cost + extra materials)
| Input | Example |
|---|---|
| Completed monthly sales | 80 |
| Sales needing rework | 5 % |
| Extra hours per rework | 3 |
| Burdened hourly cost | 40 |
| Extra materials per rework | 50 |
| Calculated result | 680 per month |
Choose reliable inputs
Compare route time, vehicle cost, delivery density and collection timing. For this local delivery calculation, use completed route logs, fuel receipts and delivery records and a consistent definition of one delivery.
- Driver hours: include the portion belonging to this delivery or reporting period, and record where the value came from.
- Vehicle cost: include the portion belonging to this delivery or reporting period, and record where the value came from.
- Route density: include the portion belonging to this delivery 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 does rework matter beyond the replacement material?
Extra labour consumes both cash and capacity that could otherwise deliver new work.
Excludes customer churn and reputational effects; rates must be measured or labelled scenarios.
What if this input changes?
If completed monthly sales rises by 10%, this example changes by 68 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.
