What is SaaS Quick Ratio?

The SaaS quick ratio compares recurring revenue inflows (new, expansion, and reactivation MRR) with revenue outflows (churned and contraction MRR) over the same period. It shows how many dollars of new and expanded MRR you create for every dollar you lose, making it a fast proxy for growth quality, unit economics, and long-term value creation.

A high quick ratio means your go-to-market motion, product, and retention are working together to compound MRR; a low ratio warns that acquisition spend may be propping up a leaky subscription base. Founders, CFOs, and investors use it alongside ARR growth, NRR, gross margin, and cash runway to judge whether growth is efficient or just expensive.

Formula

Core definition using MRR components:

SaaS Quick Ratio = (New MRR + Expansion MRR + Reactivation MRR) / (Churned MRR + Contraction MRR)

Where you can also define:

Growth MRR = New MRR + Expansion MRR + Reactivation MRR
Churn MRR = Churned MRR + Contraction MRR
SaaS Quick Ratio = Growth MRR / Churn MRR

Net new MRR for the period is:

Net New MRR = Growth MRR − Churn MRR

Example

Assume a SaaS business reports the following MRR movements this month:

  • New MRR: $10,000
  • Expansion MRR: $4,000
  • Reactivation MRR: $1,000
  • Churned MRR: $3,000
  • Contraction MRR: $2,000

First compute growth and churn:

Growth MRR = 10,000 + 4,000 + 1,000 = 15,000
Churn MRR = 3,000 + 2,000 = 5,000

Now the quick ratio and net new MRR:

SaaS Quick Ratio = 15,000 / 5,000 = 3.0
Net New MRR = 15,000 − 5,000 = 10,000

A quick ratio of 3× means the company adds $3 of growth MRR for every $1 lost to churn and downgrades—typically read as healthy but with room to improve retention and expansion toward best-in-class benchmarks around 4× and above.

How to Use the SaaS Quick Ratio Calculator

Enter your MRR movements for a given month (or quarter), and the calculator will show your SaaS Quick Ratio, Net New MRR, and a simple health category.

Choose your time period

  • Decide which period you’re analyzing (e.g., last month) and make sure all MRR figures come from that same period.

Enter growth MRR

  • Fill in New MRR, Expansion MRR, and Reactivation MRR based on your billing or revenue reports for the chosen period.

Enter churn and contraction

  • Add your Churned MRR (cancellations) and Contraction MRR (downgrades/discounts) so the tool can compute lost revenue.

Review the results table

  • Check Growth MRR, Churn MRR, Net New MRR (Growth − Churn), and the calculated SaaS Quick Ratio with its health label (e.g., “Healthy”).

Interpret and compare over time

  • Track this ratio every period to see if growth is strengthening or if churn/contraction is starting to erode your net MRR.

Frequently Asked Questions

What is considered a “good” SaaS Quick Ratio for B2B subscription companies?

As a rule of thumb, <1 means churn is winning (red flag), 1–2 is weak/fragile growth, 2–4 is acceptable but needs improvement, and 4+ is typically viewed as healthy, investor-friendly growth for SaaS.

Over what period should I plug in my MRR numbers (monthly, quarterly, annual)?

This metric is normally tracked monthly using MRR, but many teams also roll it up quarterly; the key is to keep the same period across all inputs so growth and churn are comparable.

Should I include reactivated customers in New MRR or treat them separately?

In this calculator, reactivated customers are entered as “Reactivation MRR” and counted as part of growth in the numerator; that keeps them visible while still measuring how well total inflows offset churn and contraction.
