## Description

When you're scaling a business, it's easy to get buried in spreadsheets and lose sight of whether a new ad campaign is actually profitable. You need to know if the money coming in from a customer over their lifetime actually covers what you spent to find them in the first place. This Connector handles that heavy lifting by pulling your spend and revenue data into clear financial metrics. Instead of guessing, you can see the exact cost per customer and the projected value of every user you sign up. It's about moving from a feeling of growth to a fact of profitability. By connecting this to the Vinkius catalog, you give your agent the ability to run these numbers on the fly, helping you spot unsustainable growth before it drains your budget. It turns raw data into a clear verdict on your health, allowing you to pivot your strategy with confidence.

## Tools

### calculate_cac
Calculates the cost to acquire a customer for each marketing channel based on your spend and new user counts. This helps you identify which sources are the most efficient for your budget.

### calculate_ltv
Estimates the total revenue a customer generates by factoring in ARPU, churn, and gross margins. It helps you understand the long-term value of your user base.

### evaluate_profitability
Combines LTV and CAC data to give you a payback period and a clear profitability rating. Use it to get a final verdict on your current growth strategy.

## Prompt Examples

**Prompt:** 
```
I spent $5,000 on TikTok and got 50 new users. What's my CAC?
```

**Response:** 
```
Based on your spend of $5,000 and 50 new customers, here is your CAC breakdown:

* **Channel:** TikTok
* **Total Spend:** $5,000
* **New Customers:** 50
* **CAC:** $100.00

This means it currently costs you $100 to acquire one paying user from TikTok.
```

**Prompt:** 
```
My ARPU is $100, churn is 2%, and my gross margin is 70%. What's my LTV?
```

**Response:** 
```
Using your revenue and retention data, here is your projected Lifetime Value:

* **ARPU:** $100
* **Churn Rate:** 2%
* **Gross Margin:** 70%
* **Projected LTV:** $3,500.00

This represents the total value a customer brings over their lifetime based on your current metrics.
```

**Prompt:** 
```
I have an LTV of $500 and a CAC of $400. Is my growth profitable?
```

**Response:** 
```
Here is the profitability evaluation for your current growth strategy:

* **LTV:** $500
* **CAC:** $400
* **LTV:CAC Ratio:** 1.25:1
* **Verdict:** Warning

**Analysis:** A ratio of 1.25:1 is quite low. You are barely covering your acquisition costs. You should look for ways to reduce your CAC or improve your retention to reach an Optimal ratio (usually 3:1 or higher).
```

A marketer sees high spend on Facebook but low conversion. They ask the agent to run calculate_cac to see if the cost per lead justifies the budget.

### Predicting SaaS Retention Value
A founder wants to know if their churn rate is killing their growth. They use calculate_ltv to see how much revenue they lose every month.

### Launching a New Product
A team wants to see if a new product is viable. They use evaluate_profitability to see if the projected LTV:CAC ratio meets their minimum requirements.

### Comparing Organic vs Paid Growth

## Frequently Asked Questions

**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` tool. 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 tool track CAC by channel?**
Yes. The `calculate_cac` tool 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.
