The SaaS quick ratio measures growth efficiency by comparing revenue gained (new plus expansion) to revenue lost (churn plus contraction) in a period. A ratio above 1 means you are growing faster than you are losing. It reveals whether growth is healthy or being undermined by churn.

The quick ratio cuts through a flattering top-line number to ask a blunt question: for every dollar of revenue you add, how much are you losing out the back? A ratio of 4 means strong, efficient growth. A ratio near 1 means you are adding and losing at nearly the same rate, which is exhausting and fragile, however good the growth number looks.

Example:

Adding $400k in new and expansion revenue while losing $100k to churn gives a quick ratio of 4, meaning growth strongly outpaces losses.

What is a good SaaS quick ratio?

Above 1 means growth outpaces losses. A ratio of 4 or higher signals efficient, healthy growth; near 1 signals churn is undermining new revenue.

What does the quick ratio reveal that growth rate hides?

Whether your growth is efficient. A healthy growth rate can mask heavy churn if you are adding and losing revenue at similar rates.
