Below one and the bucket's winning. Term : SaaS Quick Ratio Popularized : Social Capital / Mamoon Hamid (2015-era) Formula : (New + expansion MRR) ÷ (churned + contracted MRR) Bands : >4 strong; <1 shrinking ## Forms & parts of speech quick ratio · noun (SaaS sense) Growth-to-leak efficiency. "Our **quick ratio** dropped to 1.5 — we're adding revenue but the churn faucet's open wide." ## Definition in plain terms The SaaS quick ratio (distinct from the accounting liquidity ratio of the same name) measures growth efficiency: new MRR plus expansion MRR, divided by churned MRR plus contracted MRR. It answers 'for every dollar of recurring revenue we lose, how many do we gain?' A quick ratio of 4 means $4 added for every $1 lost — efficient growth; a ratio of 1 means the bucket fills exactly as fast as it leaks. ## The mechanics Popularized by investor Mamoon Hamid (then Social Capital) around 2015, the bands run: above 4 is strong (especially for early-stage), 2-4 is healthy, and below 1 means the company is shrinking despite adding customers — the leak beats the inflow. Its power is showing the GROSS flows the net MRR number hides: two companies with identical net growth can have wildly different quick ratios, and the one growing $5 to lose $4 is far more fragile than the one growing $2 to lose $0.50. It exposes the leaky-bucket trap that net metrics paper over. ## When it matters The quick ratio matters as the leaky-bucket detector — the diagnostic for companies that look like they're growing (positive net MRR) but are actually running hard to stay in place. For marketers it reframes the retention-versus-acquisition argument with arithmetic: a low quick ratio means plugging churn returns more than adding acquisition (a dollar of saved churn improves the ratio more than a dollar of new MRR at the margin). It pairs with NDR and logo churn as the gross-flow complement to net metrics. **Worked example.** A SaaS celebrates steady net MRR growth until the quick ratio exposes the truth: 1.3 — it's adding $1.30 for every dollar lost, sprinting to inch forward. The gross flows reveal a churn faucet the net number hid. The board reprioritizes: the churn-reduction projects (onboarding fixes, at-risk-account intervention, failed-payment recovery) that improve the DENOMINATOR get funded ahead of acquisition. Quick ratio climbs to 3.1 over three quarters — and the same acquisition spend now produces real growth instead of bucket-refilling, because the leak finally got plugged. **Failure modes to watch.** Confusing it with the accounting quick ratio; trusting net MRR while the quick ratio reveals the leak; ignoring that plugging churn improves the ratio faster than adding MRR at the margin; and reading it without stage context (early companies should run high). ## Synonyms & antonyms ### Synonyms SaaS quick ratiogrowth quick ratio ### Antonyms leaky-bucket growthnet-MRR complacency ## Origin & history Popularized for SaaS by investor Mamoon Hamid (co-founder of Social Capital, later Kleiner Perkins) around 2015 — borrowing the 'quick ratio' name from accounting for a growth-efficiency gauge; it spread through the metrics-driven SaaS-investing community as a leaky-bucket detector.
