Choose reliable inputs
Include software licences, delivery time, revisions and ongoing support when costing a project. For this graphic design calculation, use project time logs, licence invoices and retainer scopes and a consistent definition of one design project.
- Creative hours: include the portion belonging to this design project or reporting period, and record where the value came from.
- Revisions: include the portion belonging to this design project or reporting period, and record where the value came from.
- Licensed assets: include the portion belonging to this design project 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.
How much revenue depends on my largest client?
Use the same reporting period. Revenue exposure does not directly measure profit or replacement probability.
What if this input changes?
If revenue from largest customer rises by 10%, this example changes by 3 %. 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.
