Choose reliable inputs
Compare route time, vehicle cost, delivery density and collection timing. For this freight brokerage calculation, use completed route logs, fuel receipts and delivery records and a consistent definition of one shipment.
- Carrier charges: include the portion belonging to this shipment or reporting period, and record where the value came from.
- Admin time: include the portion belonging to this shipment or reporting period, and record where the value came from.
- Claim handling: include the portion belonging to this shipment 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.
Does every missed call represent a lost sale?
Some callers are duplicates, existing customers, or poor fits. Use unique qualified enquiries and a measured conversion rate.
Recovery and conversion rates are hypothetical unless measured; do not treat this as guaranteed revenue.
What if this input changes?
If missed enquiries per month rises by 10%, this example changes by 90 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.
