Tired of messy Excel sheets for MRR & LTV? I built SaaS Metrics Box (100% Free Toolkit)

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:

1. Digging through messy, half-broken Excel formulas.

2. 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:

1. Are there any specific metrics or calculations you wish were easier to run?

2. What’s the biggest pain point in your current financial planning workflow?
