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

  1. 1Enter new MRR and expansion MRR.
  2. 2Enter churned MRR and contraction MRR.
  3. 3Add the growth drivers and the loss drivers separately.
  4. 4Divide total growth by total loss to get the quick ratio.
newMrrMRR added from newly acquired customers in the month.
expansionMrrMRR added from upgrades, cross-sells, and seat additions in the month.
churnedMrrMRR lost from customers who canceled completely in the month.
contractionMrrMRR lost from downgrades and seat reductions in the month.
resultQuick ratio: the multiple of MRR growth versus MRR loss.

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.

New MRR10000
Expansion MRR3000
Churned MRR4000
Contraction MRR1000
  1. 1MRR growth = $10,000 + $3,000 = $13,000.
  2. 2MRR loss = $4,000 + $1,000 = $5,000.
  3. 3Quick ratio = $13,000 / $5,000 = 2.6x.
  4. 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

Negative net growthBelow 1x

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.

Fragile1-2x

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.

Good2-3x

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.

Strong3-4x

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.

Elite4x+

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.

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.

FAQ

What if churned MRR is zero for the month?

With zero loss, the denominator is zero and the ratio is mathematically undefined. If you have positive growth, treat the ratio as effectively infinite, which is excellent but rare; verify the data before celebrating a month with no churn.

What counts as contraction MRR?

Contraction is recurring revenue lost without a full cancellation: downgrades to cheaper plans, fewer seats, or removed add-ons. DeskOps's $1,000 downgrade was contraction, distinct from the $4,000 in full cancellations that count as churn.

Is the quick ratio more important than net revenue retention?

They answer different questions. NRR shows whether existing customers expand faster than they contract, while the quick ratio adds new business to the picture. A strong quick ratio with weak NRR means acquisition is masking retention problems, which is a red flag.

What is a good SaaS quick ratio?

A quick ratio above 4 is considered excellent, meaning the company is growing MRR more than 4x faster than losing it. A ratio between 2 and 4 is healthy. Below 2 indicates that growth is barely outpacing churn, and below 1 means the company is shrinking.

How often should the quick ratio be calculated?

The quick ratio should be calculated monthly alongside other core SaaS metrics. Monthly tracking reveals trends and seasonality. If your business has significant seasonal variations, compare the same month year over year for a more accurate trend assessment.

What is the difference between quick ratio and net MRR growth rate?

The quick ratio focuses on the balance between growth and loss drivers, while net MRR growth rate measures the percentage change in total MRR. Both are valuable: quick ratio shows the efficiency of growth, while net MRR growth rate shows the magnitude of growth.

Methodology

ApproachThe calculator adds new MRR and expansion MRR to form total growth, adds churned MRR and contraction MRR to form total loss, and divides growth by loss. The quotient is the quick ratio, a measure of how many dollars of MRR growth are generated for each dollar lost.
SourceThe quick ratio is a widely used SaaS growth efficiency metric popularized by venture capital firms including Bessemer Venture Partners.
UpdatedJuly 2026
RoundingResults are rounded to 1 decimal place and reported as a multiple (x).
UnitsAll MRR inputs are in a single currency; the result is a unitless multiple.
ExclusionsExcludes one-time fees, setup charges, and professional services revenue, which are not recurring and would distort growth efficiency.
LimitationsA single month can be distorted by one large deal or one large churn event. The ratio also says nothing about the size of growth in dollars, so pair it with net MRR growth rate.
