Before you connect
Questions about LTV:CAC Calculator API.
The practical details behind the request, access and result.
What does the LTV:CAC Calculator MCP actually do?
It calculates the cost to acquire a customer and the value they bring over time. It then gives you a clear verdict on whether your current marketing spend is profitable.
Can I use the LTV:CAC Calculator MCP for my e-commerce store?
Yes. It works for any business model that has a cost to acquire a customer and a measurable revenue per user, including e-commerce and SaaS.
How do I find out which marketing channel is most profitable?
You can provide your agent with spend and customer data for multiple channels. The Connector will calculate the CAC for each one so you can see which source is the most efficient.
What is a good LTV:CAC ratio?
While it varies by industry, a 3:1 ratio is often considered a healthy target. This Connector helps you identify if you are hitting that goal or if your growth is at risk.
Does the LTV:CAC Calculator MCP handle my actual ad spend?
No, it does not connect to your ad accounts. You provide the spend and customer numbers, and it performs the financial analysis for you.
Can this help me see my payback period?
Yes. It calculates how many months it takes for a customer to generate enough revenue to cover the cost of acquiring them.
What is the most critical ratio to monitor?
The LTV:CAC ratio is paramount. You can use evaluate_profitability by feeding it the results from calculate_ltv and calculate_cac. A healthy ratio (5:1 or higher) confirms that your acquisition spending generates sufficient long-term revenue.
How do I calculate LTV?
Use the calculate_ltv capability. You must provide three inputs: ARPU, gross margin percentage (as a decimal), and the annual churn rate (also as a decimal). The resulting projected LTV is critical for subsequent steps.
Does this capability track CAC by channel?
Yes. The calculate_cac capability accepts a JSON array of channel data, allowing you to calculate the specific Cost per Customer (CAC) for every source--be it paid search or social media.
