81% of brands say influencer ROI is impossible to measure. But it's not. With proper UTM tracking, promo codes, affiliate commission structures, and CRM attribution, you can calculate exact revenue per influencer. This calculator + framework walks through the entire process.

The ROI Formula: What You Need to Track

ROI = (Revenue - Cost) / Cost × 100. Example: Campaign costs Rs. 50,000. Generates Rs. 180,000 in attributed revenue. ROI = (180K - 50K) / 50K × 100 = 260% ROI. But only if you're tracking attribution properly. Most brands skip this step and declare campaigns "successful" without knowing if they actually drove sales.

Key Metrics Every Brand Should Track

Cost per influencer: Total budget divided by number of creators. Reach & impressions: Total audience reached via influencer posts. Engagement rate: Likes, comments, shares as % of total reach. Click-through rate: UTM clicks as % of reach. Cost per conversion: Total campaign budget divided by actual conversions. Revenue per influencer: Attributed revenue assigned per creator. Customer lifetime value: Long-term value of customers acquired through that influencer. ROAS: Revenue divided by ad spend (most important metric).

4 Methods to Track Influencer Revenue Attribution

1. UTM Parameters: Add unique UTM tracking to each influencer's link — utm_source=influencer, utm_medium=social, utm_campaign=[creator_name]. Track all traffic through Google Analytics. 2. Promo Codes: Generate unique discount codes per influencer. When applied at checkout, you know that customer came from that creator. 3. Affiliate Links: Pay influencers a commission on sales they drive. E-commerce platforms (Shopify, WooCommerce) integrate affiliate tracking natively. 4. CRM Attribution: Tag leads as "influencer_[name]" in your CRM. Track deal progression, close rates, and customer lifetime value per influencer.
