SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Measuring the return on investment of influencer marketing campaigns is difficult because value comes from multiple sources: direct sales, earned media, and long-term customer value. This Skill provides structured methodologies to calculate, compare, and communicate campaign ROI to stakeholders. ## Core Features & Use Cases - Multiple ROI Methodologies: Computes direct ROI, ROAS, earned media value (EMV), cost efficiency metrics (CPM, CPE, CPA, CAC), and LTV-based ROI. - Attribution Modeling: Applies first-touch, last-touch, linear, time-decay, and position-based attribution to allocate revenue across influencers. - Influencer-Level Analysis: Ranks individual influencers by ROI, ROAS, and budget efficiency, segmented by tier (macro, micro, nano). - Use Case: Given a $25K campaign that generated $72K revenue and 2.1M reach, produce a full ROI report showing 188% ROI, 2.88:1 ROAS, EMV estimates, and an executive-ready summary with recommendations. ## Quick Start Calculate the ROI for my influencer campaign with a $25,000 budget that generated $72,000 in revenue and 2.1 million reach.

Frequently Asked Questions about roi-calculator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I calculate ROI for an influencer marketing campaign?▼

Calculate direct ROI by subtracting total investment from revenue, dividing by investment, and multiplying by 100. For example, $72K revenue on $25K spend yields 188% ROI and a 2.88:1 ROAS, meaning $2.88 returned per dollar spent.

What is earned media value and how is it calculated?▼

Earned media value estimates what the same reach and engagement would cost through paid media. It is computed by multiplying impressions by industry CPM rates or engagements by cost-per-engagement rates, then comparing the total against campaign spend.

Which attribution model should I use for influencer campaigns?▼

The choice depends on your customer journey: last-touch suits conversion-focused campaigns, first-touch suits awareness goals, and linear or position-based models distribute credit across multiple influencer touchpoints. The skill compares all models side by side.

What is a good ROAS benchmark for influencer marketing?▼

Benchmarks vary by industry: beauty averages 3:1 with 5:1 considered good, fashion averages 2.5:1, and food and beverage averages 2:1. A ROAS above 2:1 is generally the minimum threshold for a profitable campaign.

What are the limitations of EMV-based ROI measurement?▼

EMV is an estimate that varies significantly by methodology and assumed CPM or CPE rates. It should be used for directional comparison rather than absolute measurement, and paired with direct revenue metrics for a complete picture.
