Growth marketing implements a data-driven approach to business growth, so having clear KPIs and measurable metrics is key to your success.
As a growth marketer, 5 metrics you should be tracking are:
✅ CAC
✅ LTV
✅ Conversion Rate
✅ Churn Rate
✅ Marketing ROI
These will give you a clear view of efficiency, retention, and profitability—helping you scale smarter and faster.
Check out below for more info, as well as some formulas 📈 you can add to your toolkit ⛏️.
Customer Acquisition Cost (CAC)
Use CAC to determine the efficiency of your campaigns. Keeping CAC low is essential for profitability and scaling the business sustainably.
How to calculate
Add marketing and sales expenses over a specific period and divide by the # of new customers acquired in the same period.
Customer Lifetime Value (LTV)
This is the total revenue a single customer is expected to generate over the entire course of your relationship. It allows you to determine if customer acquisition efforts are cost-effective long term.
How to calculate
Multiply a customer's average purchase value by their purchase frequency and average customer lifespan.
Conversion Rate
The percentage of website visitors or potential customers who complete a desired action such as making a purchase, completing a form on a landing page or downloading an app.
How to calculate
The number of conversions divided by the total number of visitors, multiplied by 100.
Churn Rate
This is the rate at which customers stop doing business with you. A high churn rate shows a potential problem with customer retention. Lowering churn is critical for long-term growth and profitability, as retaining customers is often more cost-effective than acquiring new ones.
How to calculate
Divide the number of customers lost during a time period by the number of customers at the beginning of that period.
Return on Marketing Investment (ROI)
Tracking ROI helps you understand which marketing activities are driving the best profitability for the business, allowing you to allocate budget and resources to the most effective channels and tactics.
How to calculate
Try this formula:
[(Revenue Generated by Campaign - Campaign Cost) / Campaign Cost] x 100%.
