Mastering SaaS Unit Economics

Building a sustainable B2B SaaS business requires more than just a great product; it requires a math equation that works. This calculator helps you visualize your marketing funnel and understand the unit economics that determine your startup's viability.

The Funnel: Traffic to Revenue

Traffic Sources & Conversion

Your growth engine starts with Visitors. We separate Paid (Ads) from Organic traffic because they have different costs. The efficiency of your funnel is measured by conversion rates: Visitor-to-Trial and Trial-to-Paid. Small improvements here compound significantly over time.

The Golden Metrics

CAC (Customer Acquisition Cost)

How much do you spend to get one customer? This includes ad spend, tools, and team salaries. If your CAC is too high, you burn cash too fast.
Formula: (Marketing Spend + Salaries) / New Customers

LTV (Lifetime Value)

How much is a customer worth? LTV is the total revenue you expect from a single customer before they churn. Higher retention (longer lifespan) and higher pricing (MRR) drive this up.
Formula: Average MRR × Average Lifespan (Months)

The LTV:CAC Ratio

This ratio tells you if your business model is scalable. A 3:1 ratio (3x return on spend) is the industry benchmark for a healthy SaaS.

  • < 1:1: You lose money on every customer.
  • 3:1: Healthy growth.
  • > 5:1: You might be under-investing in growth.
