roi-calculator
Use when the user asks to "calculate influencer ROI", "prove campaign value", or "what was our ROAS"; produces direct ROI/ROAS, earned media value, attribution-modeled revenue, LTV-based ROI, and a stakeholder-ready summary. Not for building the full slide/written report — use report-generator.
Why this skill is useful

What this skill does
ROI Calculator This skill helps you calculate and communicate the return on investment for influencer marketing campaigns using various methodologies appropriate for your goals and available data. Cross-discipline (paid ads): this is the shared return-math engine for paid ads — paid-measurement-loop, attribution-reconciler, and budget-optimizer delegate ROAS/CPA/payback ratios here rather than recomputing them. Save paid runs under memory/ad/roi-calculator/. Quick Start Shortest invocation: Common scenario — compare methods before reporting: Skill Contract Reads: campaign spend breakdown, results data (reach, impressions, engagements, clicks, conversions, revenue, new customers), AOV and repeat-rate data if LTV is in scope, any prior performance output from performance-analyzer. Writes: ROI calculation file at memory/influencer/roi-calculator/YYYY-MM-DD-<topic>.md containing direct ROI/ROAS, EMV, cost-efficiency metrics, attribution-modeled revenue, LTV-based ROI, by-influencer ROI, and a summary report block. Promotes: only with separate authorization, durable headline numbers with their attribution window, source, and uncertainty; a calculation request alone does not authorize hot-cache writes. Done when: 1. At least one ROI methodology is computed with the inputs and formula shown. 2. Each headline metric is stated against a declared, source-dated comparison target; no universal benchmark is invented. 3. A bottom-line assessment (profitable / break-even / loss) and 1-3 recommendations are written. Primary next skill: report-generator Handoff Summary Emit the standard shape from skill-contract.md §Handoff Summary Format. Data Sources This family is Tier 1 — it works with no live integrations. Ask the user for spend and results data and compute everything from those inputs. Connectors below can pull the numbers automatically when available: ~~social platform analytics — reach, impressions, engagements, video views per platform for EMV and cost-per-metric math. …
