Unit Economics & LTV/CAC Health Checker

Analyzes your startup's financial inputs to audit key metrics like LTV, CAC, Payback Period, and churn risks.

Use Case

Use this when preparing reports for investors, auditing your marketing spend efficiency, or preparing for a board meeting.

AI Prompt

Act as a veteran CFO and SaaS metrics specialist. Analyze the following financial inputs from my startup to assess our unit economics health and identify risks. My current inputs: Average Revenue Per Account (ARPU): [Insert value, e.g., $150/month], Customer Acquisition Cost (CAC): [Insert value, e.g., $450], Gross Margin %: [Insert value, e.g., 80%], Monthly Churn Rate: [Insert value, e.g., 3%]. Calculate and provide a detailed analysis of: 1. Customer Lifetime Value (LTV) and the LTV:CAC ratio. 2. CAC Payback Period (in months). 3. An assessment of whether this engine is scalable or risky, plus 3 targeted strategies to optimize these metrics.

How to Use

1Calculate your average ARPU, CAC, Gross Margin, and Churn.
2Input these raw numbers into the prompt's variables.
3Analyze the feedback to find areas where you can reduce churn or optimize CAC.

Example Output

With an ARPU of 150 dollars and a monthly churn rate of 3 percent, your Customer Lifetime Value is calculated at 5000 dollars. Given your Customer Acquisition Cost of 450 dollars, your LTV to CAC ratio is an exceptional 11.1 to 1. Your CAC Payback Period is exactly 3.75 months, meaning you recoup your spend quickly. While these are highly efficient metrics, keep an eye on your churn rate, as even a minor increase to 5 percent will drop your LTV significantly. Focus on scaling your acquisition spend safely while monitoring long-term cohort retention.
