Ehsan's Analysis
The SaaS Quick Ratio (new MRR + expansion MRR) ÷ (churned MRR + contraction MRR) measures whether your business is growing or shrinking in absolute terms. A ratio above 4 is excellent (for every $1 lost, you add $4). Between 2-4 is healthy. Below 2 signals a leaky bucket. Mamoon Hamid of Kleiner Perkins popularized this metric, and it remains one of the cleanest health signals for SaaS boards. The quick ratio reveals something growth rate hides: a company growing 50% annually with a quick ratio of 1.5 is barely staying ahead of churn and will decelerate rapidly. A company growing 30% with a quick ratio of 5 has minimal churn and sustainable momentum. Track quick ratio monthly and investigate immediately if it dips below 3 — this usually signals either a competitive displacement (accounts churning to a specific competitor) or a pricing problem (customers downgrading).
