A free calculator that estimates how much MRR you're losing each month to involuntary churn, failed payments, and trial drop-off. Broken down by source. No signup, no Stripe required.

## What this page covers
A standalone tool to quantify hidden revenue losses across the three most common leak sources for SaaS companies.

## What it computes
- Monthly leak total — dollars of MRR lost per month across all three sources
- Annual impact — leak total × 12 plus compounding effects
- Breakdown by source:
- Involuntary churn (customers who fail to renew due to payment issues, not cancellation)
- Failed payments (charges that decline and aren't recovered)
- Trial drop-off (free trials that don't convert)
- Peer comparison — how your leak rate compares to median SaaS at your stage

## Inputs
- Average customer LTV
- Monthly churn rate
- Payment failure rate (% of charges that decline)
- Trial-to-paid conversion rate (if you run trials)

## What the agents do with these leaks
Revenue Leak is a static calculator. North Metric's Pro agents act on each leak source in production:

• Payment Recovery scans failed payments and expiring cards, scores each by recovery probability per failure code, and recommends retry windows.
• Churn Radar identifies at-risk customers before cancellation using engagement and payment health signals.
• Trial Closer surfaces expiring trials with conversion likelihood and recommended nudges.
