Choose reliable inputs
Include preparation, delivery and post-production rather than shoot or event time alone. For this event planning calculation, use production schedules, vendor quotes and editing logs and a consistent definition of one event.
- Coordination hours: include the portion belonging to this event or reporting period, and record where the value came from.
- Vendors: include the portion belonging to this event or reporting period, and record where the value came from.
- Travel: include the portion belonging to this event 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.
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.
