Quick ratio
`max(churnedArr, 1)` avoids divide-by-zero when you mirror board slides where churn rounds to zero.
Example scenario
Finance pulls quarterly bookings where new-logo ARR totals $310,000 and expansion including seat adds lands $185,000 while churn-plus-contraction dollars removed from the install base equal $92,000 after reconciling credits. Gross bookings added sum to $495,000 against $92,000 lost, producing a quick ratio near 5.38× at defaults. Net new ARR after leakage is $403,000, which leadership reads beside pipeline coverage because quick ratio ignores acquisition spend efficiency.

How to use the quick ratio
- Input new logo ARR added ($) from CRM bookings tied to first-time customers within the measurement quarter.
- Input expansion or upsell ARR ($) booked from existing accounts according to your RevOps definition before recognition spreads.
- Input churned plus contraction ARR lost ($) covering cancellations and hard downgrades net of saves captured as expansion elsewhere.
- Read quick ratio and net new ARR; compare trailing quarters before tying results to sales efficiency or burn-multiple conversations.
SaaS quick ratio context
- Venture commentary bands
- Operating metrics commentary often treats SaaS quick ratios around 4× or higher as a healthy gross growth-to-churn cushion, though segment and contract length shift acceptable ranges.
- Churn denominator completeness
- Best-practice denominators fold contraction and downgrade ARR into churned dollars so the ratio reflects net leakage from the prior revenue base.
- Period alignment
- Investor decks usually compute quick ratio on the same ARR booking window as numerator additions—typically quarterly—before annualizing for comparisons.
Best use cases
- Forecasting and scenario planning
- Client education and pre-qualification
- Budget and performance decision support
Frequently asked questions
Should voluntary churn differ from contraction in the denominator?
Combine them when contraction represents ARR walking out of the base; splitting labels matters for diagnostics but quick ratio math wants total dollar leakage.
Why not subtract expansion from the numerator like net retention?
Quick ratio deliberately compares gross new-plus-expansion bookings against churn dollars as a pace metric; net retention focuses on cohort retention economics instead.
Does professional services revenue belong in ARR lines?
Exclude non-recurring PS unless your firm books subscription bundles that qualify under revenue policy; mixing one-time dollars skews both numerator and denominator.
What happens when churn rounds near zero?
Mathematically the ratio spikes; use caution and disclose min(churn) floors because tiny denominators exaggerate headline multiples.
