/aaron-marketing:roi-calculator <campaign name or spend> [revenue] [results data]When to use
Use when measuring or projecting influencer campaign ROI, justifying or defending budgets, comparing ROI across campaigns or channels, evaluating individual influencer or tier value, or preparing executive-level ROI numbers. Activate when the user supplies spend and results data and wants ROI, ROAS, EMV, CPA/CAC, attribution, or LTV impact computed.

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.

Shortest invocation:
Calculate ROI for our influencer campaign: $25K spend, $72K revenue, 2.1M reach
Common scenario — compare methods before reporting:
What's the ROI of our campaign using direct revenue, EMV, and LTV-based methods?
performance-analyzer.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.memory/hot-cache.md.Emit the standard shape from skill-contract.md §Handoff Summary Format.
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.~~ecommerce / analytics — revenue, conversions, link clicks, and AOV for direct ROI and attribution.~~CRM — new-customer counts, repeat-purchase rate, and lifetime value for LTV-based ROI.~~influencer database — per-influencer fees and tier data for by-influencer ROI.With zero integrations, supply the investment and results tables by hand and the skill still produces every calculation. See CONNECTORS.md for the free/keyless recipe per category.
When a user requests ROI calculation, work the steps below. Each step has a fill-in template in references/roi-templates.md — link the step number to its block there.
Gather ROI inputs — campaign details, the investment (total spend) table, and the results-data table. (template)
Calculate direct ROI — Simple ROI = (Revenue − Investment) / Investment × 100; ROAS = Revenue / Investment. State profit and a Profitable/Break-even/Loss assessment. (template)
Calculate Earned Media Value (EMV) — impression-based (Impressions × CPM / 1000) and engagement-based (Engagements × CPE), then average. Flag EMV as directional, not absolute. (template)
Calculate cost-efficiency metrics — CPM, CPR, CPE, CPV, CPC, CPA, CAC, each against a benchmark; rate the campaign and compare CPA to other channels. (template)
Apply attribution modeling — run first-touch, last-touch, linear, time-decay, and position-based; recommend the model that fits the customer journey. (template)
Calculate customer lifetime value impact — LTV-Based ROI = (New Customers × Avg LTV − Investment) / Investment; project short- vs. long-term and compare customer quality to organic/paid. (template)
Calculate by-influencer ROI — per-influencer ROI/ROAS rank, investment efficiency, and ROI by tier (macro/micro/nano). (template)
Generate the ROI report summary — investment, returns, ROI by methodology, key metrics vs. benchmark, bottom line, and 1-3 recommendations. (template)
Roll up into the C³ Campaign Value Index (CVI)
This skill emits the ROI scope score of C³ and the CVI rollup. Score ROI on the 0–100 rubric in c3/roi-campaign-benchmark.md (Return · Orchestration · Impact, each on Pass/Partial/Fail → scaled to 0–100). This 0–100 ROI score is not the financial ROI % from steps 1–8 — feed the rubric score into the formula, never the percentage (R1 simply consumes your ROI%/ROAS as one of its inputs). Then combine it with the Creator and Content scope scores — from fit-scorer (ACE) and content-reviewer (ART) — as a geometric mean:
CVI = ( ACE_avg × ART_avg × ROI )^(1/3)
ACE_avg is the budget-weighted mean of the campaign's creator ACE scores; ART_avg is the simple mean of its content ART scores (per scoring-architecture §8). Keep the three scope scores beside the CVI — the index ranks and alerts, the three scores diagnose. If ACE or ART is unavailable, emit the ROI score and mark CVI pending (needs ACE/ART) rather than guessing. A blocked scope (e.g. an ART T1/T2 veto on the content, or an ACE A2/C1/E2 veto on the creator) caps the rollup — surface it, don't average it away.
