If you’re running lead generation campaigns that produce MQLs (Marketing Qualified Leads), you’ve probably been asked:
What’s the ROI?
It’s a fair question—and one that many marketers struggle to answer clearly.
In 2025, it’s no longer enough to say “we generated 100 leads.” Decision-makers want to know if those leads turned into revenue. They want to know if your campaign drove real business results—not just form fills.
This article breaks down how to calculate the ROI of your MQL campaigns in a way that’s both practical and rooted in business performance. Whether you’re reporting to stakeholders or optimizing your next campaign, this framework will help you connect the dots between lead generation and revenue.
What Is an MQL and Why It Matters for ROI
A Marketing Qualified Lead (MQL) is someone who has engaged with your business in a way that indicates interest—but who’s not yet ready for a sales conversation.
Examples include:
- Downloading a gated asset
- Subscribing to a newsletter
- Attending a webinar
- Completing a service interest form
- Visiting key landing pages multiple times
MQLs help fill your funnel and guide warm prospects toward becoming paying customers. But unless you track how many of those MQLs convert and what they’re worth, you won’t have a true picture of your return on investment.
The ROI Formula for MQL Campaigns
Let’s start with the basic formula:
ROI = (Revenue Attributed to MQLs – Cost of Campaign) ÷ Cost of Campaign
To apply this formula, you need three inputs:
- Total number of MQLs generated
- Conversion rate from MQL to Customer
- Average Revenue per Customer
- Total campaign costs (ad spend, content creation, software, etc.)
Step-by-Step Breakdown
✅ Step 1: Track the Number of MQLs
Use your CRM or marketing automation platform (HubSpot, Marketo, Salesforce, etc.) to define and track MQLs.
Make sure your MQL definition is clear and tied to real engagement—not just vanity metrics.
📍 Example: A Florida-based software company ran a Google Ads campaign offering a downloadable pricing guide. They generated 120 MQLs over 30 days by defining MQLs as users who downloaded the guide and visited the pricing page at least once.
✅ Step 2: Calculate the MQL-to-Customer Conversion Rate
Use your CRM to track how many MQLs eventually became paying customers.
Formula:
MQL-to-Customer Rate = (Number of Customers ÷ Total MQLs) x 100
If 120 MQLs resulted in 12 customers, your conversion rate is 10%.
✅ Step 3: Determine the Average Revenue per Customer
You can pull this data from your accounting or billing system. Focus on revenue generated over the first 6–12 months (especially if you offer subscription services).
If each new customer brings in $1,000 in revenue on average, multiply by the number of closed deals.
12 customers × $1,000 = $12,000 in revenue
✅ Step 4: Calculate Total Campaign Costs
Include everything:
- Ad spend (Google Ads, Facebook Ads, LinkedIn)
- Creative and design costs
- Content writing and landing page development
- Software/tools used specifically for the campaign
- Freelancer or agency fees
Let’s say your total investment was $3,000.
✅ Step 5: Plug Into the ROI Formula
Now you can calculate ROI:
ROI = ($12,000 – $3,000) ÷ $3,000 = 3.0 or 300%
That means for every $1 spent, your campaign returned $4 ($3 profit + $1 original investment).
ROI Benchmarks for MQL Campaigns
What’s a “good” ROI? That depends on your business model and sales cycle, but general benchmarks include:
| ROI % | Performance |
|---|---|
| 0–100% | Break-even or needs work |
| 100–300% | Solid for long-cycle offers |
| 300–500% | Strong for most B2B models |
| 500%+ | Excellent (often includes lifetime value) |
Note: ROI on MQL campaigns tends to improve over time, especially if you continue nurturing leads that didn’t close right away.
Bonus Tips to Improve and Track ROI More Accurately
🎯 Align MQL Criteria With Sales Readiness
If your MQLs aren’t converting, your qualification criteria may be too loose. Focus on behavioral signals that show buying intent, not just content interest.
📊 Set Up Attribution Reporting
Use UTM tracking, GA4, and CRM integration to follow leads from first click to closed deal.
💬 Get Sales Feedback
Talk to your sales team about lead quality. Are they actually closing MQLs from your campaign? If not, adjust targeting or messaging.
🔁 Consider Multi-Touch Attribution
Especially in longer sales cycles, use models that attribute value across multiple touchpoints—not just first click.
If you’re generating MQLs but not tracking ROI, you’re only seeing half the picture. Measuring the return on your lead gen campaigns helps you justify budgets, improve targeting, and align your team around what actually drives revenue.
