BestSaaSMetrics is a free financial modeler for SaaS founders and CFOs to calculate true gross-margin and churn-adjusted CAC payback periods, simulate unit economic scenarios, and benchmark against 8 real-world SaaS verticals in under 60 seconds.
Hey Product Hunt community! 👋
I'm Haris, maker of BestSaaSMetrics.
When reviewing financial models for early-to-growth stage SaaS businesses, one pattern kept showing up: standard CAC Payback formulas are dangerously oversimplified.
The textbook formula:
assumes that 100% of revenue goes toward paying off customer acquisition and that customer retention is 100%. In the real world, hosting costs, transaction fees, customer support (COGS), and churn decay push real breakeven dates 4 to 8 months further out.
If you don't model this, you risk scaling marketing before your unit economics are actually sustainable.
🛠️ What we built:
⚡ Gross-Margin & Churn-Adjusted Engine: Accounts for COGS, churn drag, and sales cycle latency to give your true cash breakeven month.
📊 Cumulative Cash Flow Trajectory: Visualizes the exact point your customer cohorts turn cash positive over a 36-month timeline.
🎯 8 Vertical Benchmark Presets: Compare your numbers instantly with Enterprise B2B, Micro-SaaS, PLG, FinTech, HealthTech, EdTech, SalesTech, and DevTools.
⚖️ Side-by-Side Scenario Modeling: Test whether a pricing increase or a retention improvement creates more runway.
🔓 100% Free & Ungated: No signup, no email capture, no hidden paywalls.
I’d love to hear your feedback:
What CAC payback window is your company currently targeting?
What SaaS metrics would you like us to build into our next release?
Thank you so much for the support! 🙏
