What is SaaS Quick Ratio?
The SaaS Quick Ratio measures the efficiency of a SaaS company's growth by comparing new and expansion MRR against churned and contraction MRR. It answers: "For every dollar of MRR lost, how many dollars are gained?" A ratio above 4 indicates efficient, healthy growth; below 1 means the company is shrinking.
The Formula
Quick Ratio = (New MRR + Expansion MRR) ÷ (Churned MRR + Contraction MRR)
New MRR comes from new customers. Expansion MRR comes from upgrades and upsells. Churned MRR is from cancellations. Contraction MRR is from downgrades.
Worked Example
A SaaS company has $30,000 new MRR, $8,000 expansion MRR, $6,000 churned MRR, and $2,000 contraction MRR.
- Growth MRR = $30,000 + $8,000 = $38,000
- Lost MRR = $6,000 + $2,000 = $8,000
- Quick Ratio = $38,000 ÷ $8,000 = 4.75
- Net new MRR = $38,000 − $8,000 = $30,000
📌 A Quick Ratio of 4.75 means for every $1 lost, $4.75 is gained, indicating highly efficient growth. The company is growing while maintaining strong retention.
Why This Matters
Growth quality assessment
A company adding $100K MRR while losing $80K has a Quick Ratio of 1.25, technically growing but barely. Another adding $100K and losing $20K has a 5.0 ratio, much healthier growth with better retention.
Investor metric
VCs increasingly use Quick Ratio alongside growth rate. A 100% growth rate with a 1.5 Quick Ratio is less attractive than 60% growth with a 5.0 ratio because the latter is more sustainable.
Strategic direction
Low Quick Ratio? Invest in retention before growth. High Quick Ratio? You can afford to increase growth spending. It tells you whether to fix the bucket or pour in more water.
Common Mistakes
❌ Ignoring contraction MRR
Downgrades are a form of revenue loss. Companies that only track cancellation churn miss 20-40% of their MRR erosion from plan downgrades.
❌ Not separating expansion from new MRR
Lumping expansion and new MRR together masks whether growth comes from new customers or existing customer expansion. Both are important but require different strategies.
❌ Calculating over too short a period
Monthly Quick Ratio can be volatile due to one-time events. Use 3-month or 6-month rolling averages for strategic decision-making.
