SaaS Quick Ratio Calculator
Free SaaS quick ratio calculator. (New MRR + Expansion) ÷ (Churn + Contraction). Growth health metric.
How SaaS Quick Ratio Calculator Works
Quick Ratio = (New MRR + Expansion MRR) ÷ (Churned MRR + Contraction MRR). A ratio above 4 means you're adding 4x more revenue than you're losing. Popularised by Mamoon Hamid at KPCB, this metric isolates growth momentum. Unlike NRR (which tracks existing customers), Quick Ratio captures all new revenue being added vs. all revenue being lost, providing a more direct efficiency signal.

Frequently Asked Questions
What is SaaS Quick Ratio?
SaaS Quick Ratio measures growth efficiency by comparing revenue being added (new + expansion MRR) against revenue being lost (churn + contraction MRR). Popularised by Mamoon Hamid at KPCB, it answers: for every dollar of MRR lost, how many dollars are being added?
What is a good SaaS Quick Ratio?
Mamoon Hamid's original benchmark is 4+ for top-tier SaaS. A ratio of 1 means you're exactly replacing what you lose. Below 1 means the business is shrinking. Between 1–4 is average; above 4 is where high-growth SaaS companies typically sit.
How is Quick Ratio different from NRR?
NRR looks at a cohort of existing customers. Quick Ratio compares all new and expansion revenue against all lost revenue in the same period — including new customer churn. Quick Ratio captures new business momentum more directly.
