01 / Production economics
What does the work need to cover?
Use one currency throughout. Labour is an internal allowance, not a tax treatment. Expenses are additional direct costs for this batch; delivered clips are accepted outputs.

Contribution = gross revenue × (1 − fee / 100) − cost
Break-even gross = cost / (1 − fee / 100)
Contribution is not net profit: this simplified model excludes tax, fixed overhead, refund uncertainty, payment timing and opportunity cost unless you include them explicitly. It is not a sponsor-rate recommendation or an income forecast. A 100% fee makes break-even unattainable for positive costs.

What changed across the posts?
Enter the same metric and unit for two groups. Match platform, format, observation window, paid/organic status and approximate length. Commas separate observations, not thousands.
A difference is not a cause
Relative change = (B median − A median) / A median × 100
The example deliberately contains an outlier. The mean moves more than the median. These are descriptive summaries, not a significance test, causal estimate or guarantee. A small or uneven sample, different audiences and changing topic demand can explain a difference. Do not pool platform metrics with different definitions. At a zero baseline median, relative change is undefined.
