SaaS Quick Ratio Calculator
The SaaS Quick Ratio is a growth-efficiency metric that reveals how much healthy revenue growth you generate for every dollar of revenue you lose. It divides the MRR you gained in a period — new plus expansion — by the MRR you lost — churned plus contraction. A Quick Ratio of 4 means you added four dollars of new and expansion revenue for every dollar that leaked out to churn and downgrades. Popularized by investor Social Capital, it exposes a truth that headline growth hides: two companies can grow MRR at the same rate, but the one with a higher Quick Ratio is doing it far more efficiently and durably, while the other is masking heavy churn with expensive new sales. Enter your MRR movements to measure your growth efficiency.

The Formula
Quick Ratio = (New MRR + Expansion MRR) ÷ (Churned MRR + Contraction MRR)
Understanding the SaaS Quick Ratio Calculator
A Quick Ratio of 4 or higher is generally considered the mark of an efficient, healthy growth-stage SaaS business — it means your growth engine is producing far more than it loses. As companies scale and churn naturally grows in absolute terms, maintaining a high Quick Ratio becomes harder, so the metric is especially revealing for early and growth-stage startups where efficiency should be strong.
The real power of the Quick Ratio is diagnostic. A falling ratio warns that churn and contraction are creeping up relative to your gains, even while total MRR still rises — a problem that headline growth rate completely obscures. Pair it with the individual MRR components to see whether the issue is rising churn, weakening expansion, or slowing new sales, and act before leaky retention quietly caps your growth and inflates your effective CAC.
Frequently Asked Questions
What is a good SaaS Quick Ratio?
A Quick Ratio of 4 or higher is the widely cited benchmark for an efficient growth-stage SaaS company — four dollars of new and expansion MRR for every dollar lost to churn and contraction. Above 4 is excellent; below 1 means you are losing more revenue than you are adding.
Why is the Quick Ratio better than growth rate alone?
Growth rate tells you how fast MRR is rising but hides how efficiently. Two companies with identical growth can have very different Quick Ratios — one growing durably with low churn, the other masking heavy churn with expensive new sales. The Quick Ratio exposes the quality and sustainability behind the headline number.
How is the SaaS Quick Ratio calculated?
Divide the MRR you gained — new MRR plus expansion MRR — by the MRR you lost — churned MRR plus contraction MRR — over the same period. The result shows how many dollars of growth you generate for each dollar of revenue that leaks out.
