What is
SaaS Quick Ratio
?
The SaaS Quick Ratio measures a subscription company’s ability to grow recurring revenue in spite of churn. It is calculated by taking the sum of New MRR and Expansion MRR and dividing it by the sum of Churned MRR and Contraction MRR. Essentially, it answers the question: 'For every dollar we lose to churn, how many dollars are we adding?' A Quick Ratio of 4.0 or higher is considered exceptional, indicating highly efficient growth. A ratio of 1.0 or lower means the business is stagnant, as every new dollar gained is simply replacing a dollar lost. The Quick Ratio is a favorite metric for VCs because it provides a holistic view of both the 'growth engine' and the 'retention engine' in a single number. It exposes companies that have high top-line growth but suffer from a massive churn problem, which would otherwise be hidden if only looking at gross new sales.
Benchmarks
The SaaS Quick Ratio was popularized by Mamoon Hamid at Social Capital. A score above 4 signals highly efficient growth; above 2 is considered fundable at Series A/B. Below 1 means your customer base is net-shrinking — a critical signal.
Tier | Benchmark | What It Means |
|---|---|---|
World-class | > 4 | For every $1 lost to churn/contraction, you add $4 of new/expansion MRR. Hypergrowth. |
Strong | 2–4 | Healthy and fundable. Common in well-run Series A/B companies. |
Acceptable | 1–2 | Positive but inefficient. Growth is slow relative to revenue lost. |
Danger | < 1 | You are losing more than you are gaining. Net revenue is shrinking. |
Frequently asked questions.

It measures the efficiency of growth; a ratio below 1.0 means the 'leaky bucket' is bigger than the pump.

Yes, the denominator is the sum of Churn MRR and Contraction MRR.
How often should I measure this?
Monthly measurement is essential to catch retention shifts before they become trends.
Is it better for SMB or Enterprise?
