In today’s digital landscape, brands invest heavily in influencer collaborations — but few know how to measure whether those partnerships actually work. Tracking the right influencer marketing ROI metrics is the difference between guesswork and strategic growth.
According to a 2025 Influencer Marketing Hub study, 60% of brands measure ROI based on engagement alone, while top-performing marketers combine financial and brand-lift metrics to uncover the true impact of influencer campaigns.
In this article, we’ll unpack the essential ROI metrics your brand should track, how to interpret them, and how tools like Referwo make tracking real-time performance effortless.
1. Why Tracking Influencer Marketing ROI Matters
Influencer marketing isn’t just about likes and views — it’s about tangible business outcomes like sales, engagement, and customer acquisition. Without ROI tracking, brands risk pouring thousands into campaigns with no clear sense of what’s driving growth.
By measuring influencer ROI effectively, brands can:
- Identify top-performing influencers
- Optimise campaign spend
- Understand audience engagement trends
- Scale campaigns that deliver the best results sa
On Referwo’s all-in-one platform, brands can track campaign ROI in real-time — including influencer-driven sales, discount code redemptions, and engagement performance — helping you make smarter, data-backed marketing decisions.

2. Core Influencer Marketing ROI Metrics You Need to Track
A. Engagement Rate
Engagement Rate (ER) measures how actively followers interact with influencer content — including likes, comments, shares, and saves. It’s one of the strongest indicators of audience authenticity.
Formula:
(Total Engagements ÷ Total Followers) × 100
Why it matters: A high engagement rate (typically 3–6%) signals that an influencer’s audience is active and invested — a key factor in predicting content performance.
B. Conversion Rate
This is the ultimate ROI metric — how many followers took action after engaging with influencer content.
Actions include clicks, signups, or purchases tracked via UTM links or discount codes.
Formula:
(Conversions ÷ Total Clicks) × 100
According to Statista, influencer-driven conversions outperform paid ads by up to 4x due to higher trust and authenticity.
On Referwo, you can track every sale or discount code redemption automatically — no spreadsheets, no manual data entry.
C. Cost Per Engagement (CPE)
CPE reveals how much you pay for each engagement — helping you evaluate campaign efficiency.
Formula:
(Total Campaign Cost ÷ Total Engagements)
Tracking this ensures your influencer partnerships deliver strong engagement for the money spent.
Referwo’s analytics dashboard consolidates campaign data, letting you compare influencers by cost-efficiency to maximise ROI.
D. Return on Investment (ROI)
ROI measures overall profitability. It shows how much revenue your campaign generated relative to its cost.
Formula:
((Revenue – Campaign Cost) ÷ Campaign Cost) × 100
A positive ROI means your influencer campaigns are driving profitable results.
Research by the Influencer Marketing Hub 2025 Report found that brands earn an average of $4.12 for every $1 spent on influencer marketing — a figure that climbs higher when campaigns are tracked effectively.
E. Earned Media Value (EMV)
EMV quantifies the total value of exposure generated from influencer campaigns — including social mentions, tags, and content reuse.
While EMV doesn’t directly measure revenue, it’s crucial for understanding overall brand visibility and social buzz.
How to Measure EMV
There’s no single industry-wide formula, but most marketers calculate EMV by assigning a monetary value to each engagement and impression, based on average advertising costs for similar outcomes.
Formula Example:
EMV=(Impressions×CPM)+(Engagements×CPE)+(Shares×CPS)
Where:
- CPM = Cost per 1,000 impressions (average for your ad platform, e.g. $10–$15)
- CPE = Cost per engagement (likes/comments, typically $0.05–$0.10 each)
- CPS = Cost per share (usually $0.50–$1.00 per share)
Example Calculation:
Let’s say one influencer generates:
- 100,000 impressions
- 5,000 engagements
- 200 shares
If your averages are CPM = $10, CPE = $0.08, CPS = $0.75:
(100×10)+(5,000×0.08)+(200×0.75)=1,000+400+150=$1,550 EMV
This means the influencer’s post created $1,550 worth of equivalent advertising exposure — without you paying for that ad placement.
F. Click-Through Rate (CTR)
CTR reveals how effective influencer content is at driving traffic to your landing pages or eCommerce store.
Formula:
(Clicks ÷ Impressions) × 100
A strong CTR indicates well-crafted influencer content that sparks curiosity and action — especially when aligned with targeted CTAs or unique discount codes.
G. Customer Acquisition Cost (CAC)
CAC helps brands understand how much it costs to acquire a new customer via influencer marketing.
Formula:
(Total Campaign Cost ÷ Number of New Customers Acquired)
Tracking CAC enables smarter budgeting and highlights which influencers deliver the highest-value customers.
3. Advanced ROI Metrics for Scaling Influencer Campaigns
A. Lifetime Value (LTV) of Influencer-Referred Customers
Influencer-acquired customers often have higher retention rates and spend more over time due to stronger brand trust.
Comparing LTV across influencer channels helps you identify which creators bring in the most loyal, long-term customers — allowing for smarter reinvestment.
B. Content Performance & Repurposing Value
Influencer content has value beyond initial posting. High-performing UGC (user-generated content) can be repurposed into ads, website visuals, or email campaigns.
Referwo helps brands collect and reuse influencer-generated content legally and efficiently, ensuring every dollar spent on collaborations goes further.
