Calculate Your Unit Economics in 2 Minutes

For founders who need a quick gauge as to whether customer acquisition is profitable or losing money.

🎯 Why Unit Economics Matter

Revenue growth means nothing if you're losing money on every customer.

Most SaaS founders I work with are growing fast, but they don't actually know if they're making or losing money on each customer acquisition.

They see MRR climbing. They're closing deals. But are they building something sustainable or just accelerating toward a cash crisis?

This calculator tells you in 2 minutes.


👨‍💻 Built for Founders Who:

✓ Are scaling without an FP&A team

✓ Need to know if their acquisition strategy is sustainable

✓ Are making budget decisions without a CFO

✓ Think in code, not spreadsheets

✓ Know that "profitable customer acquisition" isn't optional


What You'll Discover

Get instant clarity on the metrics that actually matter for sustainable growth

💰 Customer Acquisition Cost (CAC)

Exactly what you're spending to acquire each customer—broken down from your total sales & marketing spend

📈 Lifetime Value (LTV)

How much revenue each customer generates over their lifetime—adjusted for churn and gross margins

⚖️ LTV: CAC Ratio

The critical metric investors look at. Are you in the healthy 3:1+ zone or burning cash?

⏱️ CAC Payback Period

How many months until you recover acquisition costs. Under 12 months? You're efficient. Over 24? You've got a problem.

👥 ARPA & Retention Analysis

Average revenue per account and how customer lifetime impacts your economics

🎯 Benchmark Comparison
