Assess Unit Economics with Precision

The challenge for any growing business is knowing if spending money to acquire a customer actually generates profit. Many companies struggle to connect their marketing spend (CAC) directly to the long-term value of that customer (LTV). This gap in understanding leads to inefficient spending and unsustainable growth projections.

Our MCP provides a clear mechanism to bridge this financial intelligence gap by running three sequential, interconnected calculations:

  1. Calculate Initial Profitability: Start with calculate_contribution_margin. You input the Gross Price, COGS per Customer, and Support Cost per Customer to determine the immediate profit generated in one billing cycle.
  2. Estimate Lifetime Value (LTV): Next, use calculate_payback_period's underlying logic (or a dedicated LTV estimation tool) by feeding the monthly contribution margin and the expected Churn Rate into the model to project the total potential revenue over time.
  3. Determine Payback & Net Value: Finally, run calculate_payback_period. This step takes the projected LTV and the amortized CAC to give you two critical numbers: the exact number of months required to recover your acquisition cost, and the resulting net residual margin--the true measure of sustainable profitability.

The result is not just a number; it's an actionable blueprint for financial health. You can immediately determine if your marketing spend supports profitable growth by systematically modeling unit economics from initial margins to long-term viability.

The gross price is $100, COGS is $30, and support costs $5. The CAC is $400. Estimate the payback period.

First, I'll call `calculate_contribution_margin` with (100, 30, 5) to get a monthly margin of $65. Then, I will use `calculate_payback_period` with CAC=$400 and Margin=$65. The payback period is approximately 7 months.

I need to know if a $2,000 CAC is viable given a monthly margin of $150 and an estimated LTV of $3,000.

Running the numbers through `calculate_payback_period` shows that with a $150 margin, recovering a $2,000 CAC requires about 14 months. This is crucial for assessing long-term viability.

What if my COGS increases to $45? Calculate the new unit margin and rate the health.

I will first use `calculate_contribution_margin` (Revenue, $100; Costs, $45 + $5) to get a lower margin. Then, using that new margin, I can evaluate the unit economics health with `rate_health`.

You must first use `calculate_contribution_margin` by providing the Gross Price, COGS, and Support Cost. This establishes the core monthly profit before considering long-term effects.
