Choose reliable inputs
Compare route time, vehicle cost, delivery density and collection timing. For this courier service calculation, use completed route logs, fuel receipts and delivery records and a consistent definition of one delivery.
- Mileage: include the portion belonging to this delivery or reporting period, and record where the value came from.
- Dispatch time: include the portion belonging to this delivery or reporting period, and record where the value came from.
- Handling: 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.
Is contribution the same as net profit?
Contribution still needs to cover rent, management, software, and other fixed costs before there is net profit.
Include variable costs only here; fixed overhead is not deducted.
What if this input changes?
If revenue per delivery rises by 10%, this example changes by 80 . 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.
