How to measure SaaS Quick Ratio

The ratio of revenue gained (new + expansion) to revenue lost (churn + contraction) in a period.

Quick Ratio = (New MRR + Expansion MRR) ÷ (Churned MRR + Contraction MRR)

Why it matters: A single number for growth efficiency: above 4 means you add four dollars for every dollar you lose. It exposes the 'leaky bucket' a top-line growth rate can hide.

6 tools that produce Quick Ratio

Side-by-side: how each tool produces this number, what to read before adopting, and where to find the official docs. Saasly does not integrate with these tools — this is a reference so you can pick the right one for your stack.

Per-tool: what to know before you plug it in

Stripe

Computed (SQL / export)

Billing platform

Subscription billing platform with built-in dashboards and SQL analytics (Sigma).

Before you adopt: Requires splitting MRR movements into new, expansion, contraction, and churn — Stripe's dashboard doesn't break these out cleanly, so derive them in Sigma from subscription change events. Mis-bucketing a downgrade as churn distorts the denominator.
Pricing: Pay-as-you-go (2.9% + $0.30 per charge). Sigma analytics: free up to 1K charges/mo, then $0.02/charge.

Chargebee

Computed (SQL / export)

Billing platform

Subscription billing platform with deep enterprise feature set and analytics module.

Before you adopt: Chargebee's Analytics module exposes new, expansion, contraction, and churned MRR — combine them for the Quick Ratio. Decide first whether paused subscriptions count as churn; treating pauses as churn inflates the denominator and understates the ratio.
Pricing: Free up to $250K ARR; from $599/mo (Performance) for established SaaS.

ChartMogul

Automatic

SaaS analytics

Subscription analytics platform built for funded SaaS with Stripe/Recurly/Chargebee billing.

Before you adopt: ChartMogul exposes SaaS Quick Ratio directly from its MRR movement data. The result is only as clean as your movement classification — if plan changes aren't mapped to expansion/contraction correctly upstream, the ratio inherits the error.
Pricing: Free up to $10K MRR; then from $129/mo (Launch) to $799+/mo (Volume).

Baremetrics

Automatic

SaaS analytics

Stripe-native subscription analytics with cancellation surveys and dunning.

Before you adopt: Baremetrics surfaces SaaS Quick Ratio natively off its Stripe-derived MRR movements. Stripe-only data is the constraint — if any revenue runs outside Stripe, the new/expansion/churn inputs (and thus the ratio) are incomplete.
Pricing: From $129/mo (Metrics) to $429+/mo (Business) — seat and MRR limits.

ProfitWell (Paddle)

Computed (SQL / export)

SaaS analytics

Free Stripe-connected subscription metrics, now Paddle-owned.

Before you adopt: ProfitWell tracks the new/expansion/contraction/churn MRR movements the Quick Ratio needs, but doesn't always badge the ratio itself — read it off the MRR movement breakdown. Free tier covers the inputs; accuracy still depends on clean plan-change tracking in Stripe.
Pricing: Metrics are free; Retain (failed payment recovery) and Price Intelligently are paid add-ons.

Saasly Calculator

Manual entry

Manual calculator

Manual-entry calculator that computes the core SaaS metrics with Skok-tier classification.

Before you adopt: Enter new, expansion, churned, and contraction MRR — get the SaaS Quick Ratio with its growth-efficiency band. A sanity check when you don't yet have an analytics tool computing it from movement data.
Pricing: Free forever, no signup.
