Measure your SaaS growth efficiency
The SaaS quick ratio measures how efficiently a subscription business grows, weighing gains against losses. This calculator computes it as new plus expansion revenue divided by churn plus contraction, so you can gauge growth quality.
Why the quick ratio reveals growth quality
Two businesses can grow revenue at the same rate while being very different underneath: one adding a lot and losing a lot, another adding steadily and losing little. The quick ratio captures this by dividing the revenue gained, new customers plus expansion, by the revenue lost, churn plus contraction. A high ratio means efficient growth where gains far outweigh losses; a low one means you are filling a leaky bucket, adding revenue almost as fast as you lose it. This exposes the leaky-bucket problem that headline growth hides.
A planning estimate
This is an estimate for planning from the figures you enter, not financial or business advice. Real outcomes depend on factors beyond any single calculation, so treat the result as a guide. The calculation runs entirely in your browser, so your figures are never uploaded and stay on your own machine, which matters for business numbers you would not want to share.

Frequently Asked Questions
What is the SaaS quick ratio?
New plus expansion revenue divided by churn plus contraction. It measures how efficiently a subscription business grows relative to what it loses.
What does a high quick ratio mean?
Efficient growth, where the revenue gained far outweighs the revenue lost. A common benchmark for strong performance is around four or above.
What does a low ratio reveal?
A leaky bucket: you are adding revenue almost as fast as you lose it, so headline growth masks poor retention underneath.
Why does it matter beyond growth rate?
Because two businesses can grow at the same rate very differently. The quick ratio exposes whether growth is efficient or offset by heavy losses.
