What is Quick Ratio?
Quick Ratio measures the efficiency of your MRR growth by comparing revenue gained to revenue lost. A Quick Ratio of 4.0 means you added $4 of recurring revenue for every $1 lost to churn and contraction.
It distills the entire MRR waterfall into a single number. A company adding $50K in new MRR but losing $40K has a Quick Ratio of 1.25 — growing, but barely. Another adding $50K and losing $12.5K has a ratio of 4.0 — efficient, sustainable growth.
Unlike Net MRR Churn Rate (which measures net loss as a percentage of starting MRR), Quick Ratio focuses purely on the ratio of inflows to outflows — how hard your growth engine is working relative to what you’re losing.
The Quick Ratio formula
Worked example
July 2026: Your MRR movements for the month:
| Component | Amount | Side |
|---|---|---|
| New Business MRR | $8,000 | Growth |
| Expansion MRR | $3,000 | Growth |
| Churn MRR | $4,000 | Loss |
| Contraction MRR | $1,500 | Loss |
A Quick Ratio of 2.0 means for every $1 lost, $2 was gained. Growth outpaces losses, but there’s room to improve — either by reducing churn or accelerating acquisition and expansion.
What excellent looks like
If churn dropped to $2,000 and contraction to $750:
A Quick Ratio of 4.0 means $4 gained per $1 lost — the same growth engine now runs four times more efficiently because losses halved. This is the threshold where most benchmarks shift from “healthy” to “excellent.”
How it’s computed
Quick Ratio draws on the same state-comparison engine used by all MRR metrics. It compares your subscription base at the start and end of each period, classifies every change into one of five categories (new, expansion, reactivation, contraction, churn), then selects four of the five for its ratio:
Why reactivation stays out
Quick Ratio answers: “How efficiently are you generating net new growth?” Reactivation is a returning customer — revenue you already had, lost, and recovered. Including it conflates recovery with genuine growth, making the ratio look better without reflecting actual acquisition or expansion capability. This follows Mamoon Hamid’s original definition.
The relationship to NRR
Quick Ratio and NRR both capture the growth-vs-loss balance, but from different angles. NRR measures what percentage of starting MRR was retained from existing customers only — new business is excluded. Quick Ratio includes new business in the numerator and ignores the size of the starting base entirely. A company can have a strong Quick Ratio from aggressive acquisition even with poor NRR.
Zero denominator
When there’s no churn or contraction in a period, the formula returns 0 rather than dividing by zero. This represents perfect growth efficiency — all growth, no losses — but the numeric value is a safe fallback rather than a true measurement.
Quick Ratio vs Net MRR Churn Rate
Both metrics measure the balance between growth and loss, but from fundamentally different perspectives. Quick Ratio is about overall growth efficiency; Net MRR Churn Rate is about existing customer retention.
| Quick Ratio | Net MRR Churn Rate | |
|---|---|---|
| What it measures | Growth efficiency (ratio of inflows to outflows) | Net revenue change from existing customers (%) |
| Includes new business | Yes (in numerator) | No (existing customers only) |
| Includes reactivation | No | Yes (offsets losses) |
| Relative to starting MRR | No (purely a flow ratio) | Yes (denominator is starting MRR) |
| Best outcome | As high as possible (4+ is excellent) | Deeply negative (expansion outpaces losses) |
| Best for | Evaluating total growth engine efficiency | Measuring existing customer retention health |
Common Quick Ratio mistakes
- Including reactivation in the numerator. Some tools count reactivation as growth. This inflates the ratio and conflates recovery with new growth. The original definition excludes it — if your Quick Ratio looks higher elsewhere, check whether reactivation is included.
- Treating a high Quick Ratio as proof of healthy retention. A Quick Ratio of 4.0 can come from strong acquisition masking high churn. If your ratio is high but NRR is below 100%, your growth depends entirely on new sales — a dangerous position.
- Using all five MRR components. Quick Ratio uses only four: New + Expansion in the numerator, Churn + Contraction in the denominator. Adding reactivation to either side distorts the measurement.
- Over-indexing on small-account ratios. On accounts with minimal churn ($5/month lost), a single new subscription can produce a ratio of 100+. The math is correct, but the signal is weak — Quick Ratio is most meaningful when both sides have material values.
SaaS Quick Ratio benchmarks
Quick Ratio benchmarks are segmented by MRR tier. Higher is better — a ratio above 4 means your growth engine is highly efficient. Median Quick Ratios range from 1.8× at Seed to 2.5× at Early and Growth, with top performers reaching 4× or higher.
| Stage · MRR | Bottom 25% | Median | Top 25% |
|---|---|---|---|
| Seed · < $10K | 1.00 | 1.80 | 4.00 |
| Early · $10K – $50K | 1.50 | 2.50 | 4.00 |
| Growth · $50K – $100K | 1.50 | 2.50 | 3.50 |
| Scale · $100K – $500K | 1.50 | 2.20 | 3.50 |
| Enterprise · $500K+ | 1.50 | 2.00 | 3.00 |

Frequently asked questions
What is a good Quick Ratio for SaaS?
Above 4.0 is excellent — your growth engine adds $4 for every $1 lost. Between 2.0 and 4.0 is healthy, meaning growth outpaces losses but there’s room to improve retention or accelerate acquisition. Below 2.0 means losses are eating significantly into growth. Below 1.0 means you’re shrinking — MRR is actively declining because churn and contraction exceed new business and expansion combined.
Why doesn’t Quick Ratio include reactivation MRR?
Quick Ratio follows the original definition by Mamoon Hamid, which counts only genuinely new revenue: new business and expansion. Reactivation is recovery of previously lost revenue, not net new growth. Including it inflates the ratio and can mask weak acquisition. If another tool reports a higher Quick Ratio, check whether reactivation is included in their numerator.
What does a Quick Ratio below 1.0 mean?
A Quick Ratio below 1.0 means your business is contracting — you’re losing more MRR to churn and downgrades than you’re adding through new business and expansion. At exactly 1.0 you’re treading water: every dollar gained replaces a dollar lost, with zero net growth. To recover, focus on reducing churn or accelerating new customer acquisition and upsells.
How is Quick Ratio different from NRR?
Quick Ratio includes new business MRR in the numerator — it measures total growth efficiency across all revenue sources. NRR only measures existing customer behavior: what percentage of last period’s MRR you retained through expansion, contraction, and churn. A company can have a strong Quick Ratio from high new sales even with poor retention, while NRR would expose the weakness.
Can Quick Ratio be misleading on small accounts?
Yes. On accounts with very low churn — say $5/month lost — even a small new subscription can produce a Quick Ratio of 100 or higher. The math is correct but not indicative of a strong growth engine. Similarly, when the denominator is zero (no losses at all), the formula returns 0 instead of infinity. Quick Ratio is most meaningful when both the numerator and denominator have material values.
