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.
Why can a small invoice discount have a high annualized cost?
It buys only a short acceleration in cash receipt. Annualizing that short interval can produce a large percentage.
Simple annualization assumes repeatable terms and is not an APR or loan quote.
What if this input changes?
If discount offered rises by 10%, this example changes by 3.8083 % annualized. This shows the effect of one change; it does not predict what will happen.
