The Formula
SaaS Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)Add up the recurring revenue you gained from new customers and from existing customers expanding. Divide by the recurring revenue you lost to cancellations and downgrades. If you added 120,000 dollars and lost 40,000 dollars, your quick ratio is 3.0: you added three dollars for every one you lost.
What It Reveals That Growth Rate Hides
Two companies can post the same growth rate with completely different quick ratios, and they are not the same business. One adds 120 and loses 20 for net 100. Another adds 200 and loses 100 for the same net 100. The first is an efficient machine; the second is pouring water into a leaky bucket and compensating with brute-force acquisition. Headline growth treats them as identical. The quick ratio exposes the difference.| Component | Direction | Source |
|---|---|---|
| New MRR | Adds | New-logo customers |
| Expansion MRR | Adds | Upsell, cross-sell, seat growth |
| Contraction MRR | Subtracts | Downgrades |
| Churned MRR | Subtracts | Cancellations |
Why Efficiency Matters More as You Scale
A leaky growth engine gets more expensive every quarter, because the bigger the base, the more revenue churns in absolute terms, and the harder acquisition has to work just to stay flat. A high quick ratio means your growth compounds; a low one means it grinds. Watching the ratio trend is an early warning that shows up before it reaches the headline revenue line.
Pair It With Retention and Efficiency Metrics
The quick ratio is strongest alongside its neighbors. Net revenue retention isolates the existing base, the burn multiple measures how much you are spending to grow, and churn rate breaks down what you are losing. The combination answers how fast you are growing and how cleanly. Growth that survives the quick-ratio test is growth a board can underwrite.
Frequently Asked Questions
What is the SaaS quick ratio formula?
SaaS Quick Ratio equals (New MRR plus Expansion MRR) divided by (Churned MRR plus Contraction MRR). If you added 120,000 dollars of new and expansion MRR and lost 40,000 dollars to churn and contraction, your quick ratio is 3.0. It measures how efficiently growth outpaces losses.
What is a good SaaS quick ratio?
A ratio above 1.0 means you are growing rather than shrinking, but efficient SaaS businesses target meaningfully higher because some inefficiency is expected. The more useful read is the trend: a falling quick ratio means losses are catching up to your gross additions even if total revenue still rises.
How is the quick ratio different from net revenue retention?
Net revenue retention looks only at the existing customer base. The quick ratio includes new-logo revenue too, so it measures total growth efficiency rather than just base retention. They are complementary: NRR shows base health, the quick ratio shows whether the whole engine is adding faster than it leaks.
