What is the SaaS Quick Ratio Calculator?
The SaaS Quick Ratio Calculator measures the ratio of revenue growth from new and expansion MRR relative to revenue lost from churned and contraction MRR. A quick ratio above 4 is considered excellent, meaning the company is growing MRR four times faster than it is losing it. This metric is widely tracked by SaaS investors and leadership teams.
How does it work?
Enter your new MRR from newly acquired customers, expansion MRR from upgrades and cross-sells, churned MRR from customers who canceled, and contraction MRR from downgrades. The calculator adds new and expansion MRR, adds churned and contraction MRR, then divides growth by loss to produce the quick ratio.
Formula
(new MRR + expansion MRR) / (churned MRR + contraction MRR)
How the calculation works
How the calculation works
- 1Enter new MRR and expansion MRR.
- 2Enter churned MRR and contraction MRR.
- 3Add the growth drivers and the loss drivers separately.
- 4Divide total growth by total loss to get the quick ratio.
Worked example
Worked Example
A fictional help desk SaaS called DeskOps reviews its monthly MRR movements: new customers added $10,000, expansions $3,000, churn removed $4,000, and downgrades $1,000.
- 1MRR growth = $10,000 + $3,000 = $13,000.
- 2MRR loss = $4,000 + $1,000 = $5,000.
- 3Quick ratio = $13,000 / $5,000 = 2.6x.
- 4DeskOps grows MRR 2.6 times faster than it loses it, a good but improvable result.
Result
DeskOps has a quick ratio of 2.6x, meaning it grows MRR 2.6 times faster than it loses it, a solid result below the 4x elite threshold.
Interpretation guide
How to read your result
MRR losses exceed MRR gains, so the business is shrinking month over month.
Investigate churn and contraction causes first; growth spend is wasted while the leak is open.
Growth barely outpaces loss; one bad month of churn can flip the business into decline.
Attack churn and contraction before scaling acquisition, and track the ratio's trend monthly.
Healthy balance between growth and loss; the classic target for growing SaaS companies.
Keep expanding the ratio through expansion revenue, which adds growth without acquisition cost.
Efficient growth with controlled losses; typical of strong product-led SaaS companies.
Maintain the discipline and investigate what is driving the low loss side so it persists.
MRR grows more than four times faster than it leaks; the benchmark top SaaS companies sustain.
Beware distortion from a single large deal and validate that the ratio is structural, not luck.
Benchmarks
SaaS quick ratio benchmarks
| Metric | Typical | Strong |
|---|---|---|
| Quick ratio (all SaaS) | 2-3x | 3-4x |
| Quick ratio (product-led SaaS) | 3-5x | 5x+ |
| Quick ratio (sales-led SaaS) | 1.5-3x | 3x+ |
| Investor target zone | 3x+ | 4x+ |
Common mistakes
- - Including one-time revenue in recurring revenue calculations
- - Not separating churned MRR from contraction MRR in the analysis
- - Ignoring the quick ratio trend and focusing only on the current month value
Practical tips
Practical tips
Pull new, expansion, churn, and contraction MRR from your billing system's monthly reconciliation, not from revenue, so one-time fees stay out.
Watch the trend: one strong month from a big enterprise deal can flatter the ratio, so use a 3-month average.
Segment the ratio by plan or customer segment to see where losses concentrate.
Tackle contraction before churn; reducing downgrades is often easier than preventing cancellations.
Pair the quick ratio with net revenue retention, since a 4x ratio with falling NRR usually means expansion is carrying the story.
When should you use it?
- - Monthly SaaS growth health reviews with the executive team
- - Evaluating whether growth is outpacing churn at a sustainable rate
- - Comparing growth efficiency across different time periods or segments
- - Reporting SaaS growth metrics to investors and board members
Benefits
- - Provides a single number that captures both growth and retention performance
- - Helps identify when growth is masking underlying retention problems
- - Enables quick comparison of growth health across periods and segments
Use cases
- - SaaS growth health monitoring
- - Investor reporting and board presentations
- - Recurring revenue performance analysis
Step-by-step example
Pull new and expansion MRR from your billing system's monthly reconciliation. Calculate churned and contraction MRR from cancellation and downgrade records. Add new and expansion to get total MRR growth. Add churned and contraction to get total MRR loss. Divide growth by loss to find your quick ratio.
Real-world example
A SaaS company reports $10,000 in new MRR, $3,000 in expansion MRR, $4,000 in churned MRR, and $1,000 in contraction MRR. Their quick ratio is 2.6 ($13,000 growth divided by $5,000 loss). This means they are growing MRR 2.6 times faster than they are losing it. A ratio above 4 is ideal for most SaaS businesses.
