Quick Ratio (SaaS)
A growth-efficiency metric that measures how much gained MRR (new + expansion) is added for every dollar of lost MRR (churn + contraction): Quick Ratio = (New MRR + Expansion MRR) ÷ (Churned MRR + Contraction MRR). A quick ratio above 4 is a sign of a healthy, compounding SaaS business; below 1 means the business is shrinking. It is a better diagnostic than top-line growth because it exposes retention weaknesses that gross new-logo numbers hide.
How Quick Ratio (SaaS) works in practice
The SaaS Quick Ratio is the clearest single-number answer to “is this business actually growing or just running on a treadmill?” A quick ratio of 4 means four dollars of new or expansion MRR arrive for every dollar lost to churn and contraction — plenty of room to compound. A quick ratio of 1 means the business is perfectly flat despite whatever the top-line growth chart shows, because expansion is only covering churn. It is a particularly good diagnostic for later-stage SaaS where gross new-logo numbers look healthy but net revenue retention is quietly degrading; the quick ratio surfaces the deterioration before it shows up in ARR growth. Pair it with NRR and gross revenue retention to separate expansion strength from churn discipline.

Let's talk →This term sits in the SaaS category, which means it is most useful when evaluating subscription growth, activation, retention, expansion, and revenue efficiency. The goal is not to memorize the label. The goal is to know when it should change a decision, a page, a campaign, or a measurement setup.

The predictable, recurring revenue a SaaS company generates each month from active subscriptions. MRR growth rate and MRR breakdown (new, expansion, churned) are primary indicators of subscription business health.
The percentage of customers who cancel or do not renew within a given period. High churn erodes MRR growth and increases CAC payback period, making retention optimisation as important as acquisition for sustainable growth.
The percentage of recurring revenue retained from an existing customer cohort over a period, including expansion from upsells and cross-sells, minus churn and contraction. NRR > 100% means the business grows revenue from its existing customer base without any new customer acquisition. Companies with NRR above 120% typically command premium SaaS valuation multiples.
Revenue generated from existing customers through upsells, cross-sells, seat additions, or usage increases — as opposed to new customer acquisition. Expansion revenue carries near-zero CAC and is the most capital-efficient growth lever in SaaS. When expansion MRR exceeds churned MRR the business achieves negative net churn, growing revenue without increasing customer count.
