What is the SaaS Quick Ratio?
The SaaS Quick Ratio measures the efficiency of your revenue growth by comparing the MRR you add (from new and expansion revenue) to the MRR you lose (from churn and contractions). A Quick Ratio of 4 or higher is considered excellent and indicates that for every dollar of MRR lost, you are adding four dollars of new MRR. A ratio below 1 means you are shrinking. This metric helps you understand whether your growth is sustainable or if it is being eroded by customer losses.

The Formula
SaaS Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)
Worked Examples
High Quick Ratio (Efficient Growth)
New MRR: $30K. Expansion: $10K. Churned: $5K. Contraction: $3K.
- Numerator: $30K + $10K = $40K
- Denominator: $5K + $3K = $8K
- Quick Ratio = $40K / $8K
Low Quick Ratio (Leaky Bucket)
New MRR: $20K. Expansion: $2K. Churned: $15K. Contraction: $5K.
- Numerator: $20K + $2K = $22K
- Denominator: $15K + $5K = $20K
- Quick Ratio = $22K / $20K
What Is a Good SaaS Quick Ratio? Industry Benchmarks
| Stage / Context | Typical Value | What It Means |
|---|---|---|
| < 1 | Shrinking | Losing more MRR than adding. Business is contracting. |
| 1 – 2 | Low efficiency | Growing very slowly. High churn is eroding new sales. |
| 2 – 4 | Acceptable | Moderate growth efficiency. Improve retention to unlock faster growth. |
| 4+ | Excellent | Gold standard. Growth is efficient and churn is under control. |
How to Improve SaaS Quick Ratio
Reduce Churned MRR
Churned MRR directly shrinks the denominator and increases the quick ratio. Every $1K of monthly churn prevented has the same impact on the ratio as adding $4K in new MRR at a 4x Quick Ratio.
Build a Strong Expansion MRR Engine
Expansion MRR contributes to the numerator at zero incremental CAC. Companies with usage-based pricing or seat-based models naturally generate expansion as customers grow.
Tighten New Customer Qualification
Acquiring customers who churn within 90 days is worse than not acquiring them — it adds to your denominator next period without meaningful LTV. Better ICP qualification improves the Quick Ratio by reducing early churn.
Track Quick Ratio by Segment
Your overall Quick Ratio may look healthy while specific segments (SMB, a certain vertical) drag it down. Segment-level analysis reveals where your leaky bucket actually leaks.
SaaS Quick Ratio vs. Related Metrics
SaaS Quick Ratio vs. Net Revenue Retention (NRR)
NRR measures the revenue retained from an existing cohort as a percentage. Quick Ratio measures the efficiency of overall MRR growth by comparing gains to losses. NRR focuses on existing customers; Quick Ratio spans both new and existing.
SaaS Quick Ratio vs. Churn Rate
Common Mistakes When Calculating SaaS Quick Ratio
Excluding Contraction MRR from the Denominator
Many teams only track churned MRR and ignore contraction (downgrades). Including contraction gives a more honest view of revenue quality. A business with low churn but heavy contraction can have a misleadingly high Quick Ratio if contraction is excluded.
Confusing the SaaS Quick Ratio with the Financial Quick Ratio
The financial Quick Ratio (current assets / current liabilities) is a liquidity metric. The SaaS Quick Ratio is an MRR growth efficiency metric. They are completely different — don't confuse them in investor conversations or financial models.
Using Annual instead of Monthly MRR Movements
Quick Ratio should be calculated on monthly MRR movements to track trends in real time. Annual calculation obscures monthly variation and delays the detection of deteriorating churn patterns.
