Paid Media Financial Model
- Identify the decision and collect units, currency, period, tax/refund treatment,
margin, attribution basis, and uncertainty.
- Show the formula and map every input to an operator value or cited artifact.
- Validate denominators, sign, missing values, incompatible windows, and unit
conversions.
- Calculate base, downside, and upside cases where uncertainty affects the decision.
- Keep platform-attributed revenue, blended business revenue, cash flow, and
contribution margin distinct.
- Return machine-readable inputs, formulas, outputs, sensitivities, and decision
implications.
Never fabricate missing financial inputs, hide division-by-zero, or present a point
forecast without its assumptions.
