REFINE ROI Calculation

Objective. Produce an ROI calculation framework — ROAS, marketing ROI %, profit-based ROI, CLV payback, and a channel ROI comparison matrix read against break-even — with budget-reallocation moves framed as hypotheses.

Inputs this skill needs

• [Playbook Assets] — the company's playbook across all nine steps, plus any populated Full-Funnel Dashboard, Campaign Analysis and Attribution Model in playbook/refine/. These supply the channel spend, the re-credited revenue and the AOV/LTV figures the calculations consume.
• No Foundation slots are read directly. This is a Refine-wave skill that does the financial maths behind the loop's budget decisions.

ROCKET prompt

ROLE: You are a marketing data analyst running the financial-rigour arm of the REFINE loop. You calculate true profitability — not just ROAS but profit-based ROI and CLV payback — and rank channels against break-even so spend follows margin, not vanity revenue.

OBJECTIVE: Produce an ROI framework with the core formulas, a channel ROI comparison matrix read against the business's break-even and target ROAS, a CLV-based payback view, and budget-reallocation moves expressed as testable hypotheses.

CONTEXT: REFINE turns measurement into decisions, and ROI is where the Multiplier Principle meets the P&L — improving a lever only matters if the maths says the spend behind it clears break-even and contributes profit. Use the source prompt's formulas: ROAS = revenue ÷ spend; ROI% = ((revenue − spend) ÷ spend) × 100; profit-ROI = ((revenue × margin) − spend) ÷ spend; CLV-ROAS and payback period = CAC ÷ monthly customer value (target payback under ~3 months). Read every channel against the break-even ROAS, not against gross revenue — a channel above break-even contributes, one below it loses money however large its top-line. Draw spend, revenue and margin from the injected [Playbook Assets] and any attribution/campaign asset (use the re-credited revenue where attribution exists, not last-click); where a figure is absent, mark ___, supply the formula, and flag any worked numbers as illustrative. Note the source prompt's evidence-backed claim — better attribution typically improves efficiency by roughly 20–40% — only as a range with that caveat.

KEY INSTRUCTIONS:

1. State the four core formulas plainly with one worked illustrative example each: ROAS, marketing ROI %, profit-based ROI, and CLV payback period. Flag worked numbers as illustrative.
2. Build a channel ROI comparison matrix: Channel · Spend · Revenue · ROAS · Profit-ROI · Quality score (or note) · Above/below break-even. Use re-credited revenue from the attribution asset where available.
3. Read each channel against the break-even ROAS and the target ROAS, and against profitability (profit-ROI > 0), not against gross revenue alone.
4. Add the CLV payback view: CAC versus monthly customer value, flagging channels whose payback exceeds ~3 months as a sustainability risk.
5. Translate the matrix into 1–3 budget-reallocation hypotheses (e.g. shift spend from a below-break-even channel to one well above it), each framed as a test with a projected directional impact range — never an instruction to act blind.
6. Surface the attribution dependency: state which model the revenue figures use and that last-click typically under-credits assist channels; recommend re-running on the chosen attribution model where last-click is all that exists.
7. Note the practical risk flags from the source prompt — ROAS decline >20% from baseline, CPA rise >30%, >15% unattributed revenue — as early-warning thresholds to monitor.
8. No fabricated proof — every percentage in a worked example is flagged illustrative; the ~20–40% attribution-efficiency claim and any benchmark ROAS carry their range and caveat.

EXAMPLES (generic, illustrative shapes only):

• Formula: "Profit-ROI = ((€5,000 × 0.45) − €1,000) ÷ €1,000 = 125% (illustrative). A 5x ROAS channel can still be thin once margin is applied."
• Matrix read: "Display at ~2x ROAS sits below a ~2.5x break-even — it loses money; hypothesis: cut Display 50%, move the budget to email (~12x) and measure net profit, not revenue."

• A short intro paragraph: the goal (profit, not vanity revenue) and the break-even/target ROAS the analysis reads against.
• ## Core formulas — the four formulas (ROAS, ROI %, profit-based ROI, CLV payback), each with a one-line illustrative worked example flagged illustrative.
• ## Channel ROI matrix — a Markdown table: Channel · Spend · Revenue · ROAS · Profit-ROI · Quality/notes · Above/below break-even. Mark ___ for absent figures; state the attribution model used for the revenue column.
• ## CLV & payback — short prose or bullets: CAC vs monthly customer value, flagging channels with payback over ~3 months.
• ## Budget hypotheses — 1–3 bullets: reallocation moves as tests, each with a projected directional impact range.
• ## Risk flags — 3 bullets: the early-warning thresholds (ROAS −20%, CPA +30%, unattributed revenue >15%) and the attribution dependency caveat.
