SaaS Metrics Box
Free SaaS calculators and growth metrics tools
Hey IH community! 👋
Like many of you here, I’ve spent way too much time trying to model basic unit economics—MRR, LTV, CAC, Churn, and payback periods—for SaaS projects.
Whenever I needed a quick sanity check on my numbers, I usually ended up with two frustrating choices:
Digging through messy, half-broken Excel formulas.
Signing up for a 14-day trial of an expensive analytics tool just to run a few basic numbers.
So I decided to build SaaS Metrics Box.
💡 What is SaaS Metrics Box?
It’s a lightweight, 100% free toolkit of interactive calculators built specifically for early-stage SaaS founders, bootstrappers, and growth teams. No signups, no paywalls, no setup friction.
🛠️ What you can calculate right now:
MRR / ARR Trajectory: Project recurring revenue growth.
LTV & CAC Ratio: Check if your unit economics and payback periods are healthy.
Churn Dynamics: Model customer and revenue retention loss over time.
ROAS & Acquisition Costs: Estimate your marketing ROI quickly.
🚀 What’s Next & Seeking Feedback
I’m actively adding new tools (like SaaS Runway Calculators and Benchmark comparisons) and would love to hear from this community:
Are there any specific metrics or calculations you wish were easier to run?
What’s the biggest pain point in your current financial planning workflow?

Brutal honesty, feature requests, and feedback are all super welcome! 🙌

The no-signup, no-paywall approach makes sense for something founders usually just want to calculate quickly.
Curious which calculator people have actually been using most so far. I’d imagine the usage pattern might be pretty different from what you expected when you built the toolkit.
