💡 Practical Example
For example, evaluating a SaaS startup starting at $85,000 MRR that adds $14,000 New MRR, $6,500 Expansion MRR, $1,500 Reactivation MRR, while suffering $2,800 Contraction MRR and $4,200 Churn MRR ($7,000 total loss): Total gains are +$22,000.00. Net New MRR is \, lifting Ending MRR to $100,000.00/month ($1.20M ARR) with a SaaS Quick Ratio of \ and an NRR of 101.76% (Negative Net Churn).
📖 About Monthly Recurring Revenue (MRR
SaaS Metrics: The SaaS Quick Ratio
The SaaS Quick Ratio measures a subscription company's ability to generate new recurring revenue relative to its revenue leakage:
- Why It Matters: If a startup adds 10k in new MRR but loses 8k to churn, it is on a 'treadmill' and burning cash to stay in place.
- The Rule of 4.0x: Top-tier venture capital firms look for a Quick Ratio of 4.0x or higher, proving that new bookings and organic expansion dominate cancellations.
How to Use This Calculator
Enter your Starting Beginning MRR ( at Month Start) (e.g. 85000), New Customer MRR ( from new signups) (e.g. 14000), Expansion / Upsell MRR ( from existing accounts) (e.g. 6500), Reactivation MRR ( from returned churned accounts) (e.g. 1500), Contraction MRR ( from plan downgrades) (e.g. 2800), and Churned MRR ( from cancellations) (e.g. 4200).

The Formula
SaaS MRR Waterfall, ARR & Quick Ratio equations: New MRR = (New MRR + Expansion MRR + Reactivation MRR) - (Contraction MRR + Churned MRR) MRR = Starting MRR + Net New MRR Recurring Revenue (ARR) = Ending MRR × 12 Quick Ratio = (New MRR + Expansion MRR + Reactivation MRR) / (Churned MRR + Contraction MRR) Revenue Retention (NRR \%) = ((Starting MRR + Expansion MRR - Contraction MRR - Churned MRR) / (Starting MRR)) × 100\%

Understanding Your Result
Revenue forecasts are only as reliable as their assumptions. Bottom-up forecasting (units × price) is more accurate than top-down (% of market) for early-stage businesses. Build three scenarios: conservative (50th percentile), base (expected), and optimistic (90th percentile). If your conservative case does not reach break-even, the business model needs revision before scaling investment. Venture-backed companies typically target 3× annual revenue growth in early years; mature SaaS businesses target 20–40% annual growth.
