Measure growth efficiency in one number.

What is Quick Ratio?

SaaS Quick Ratio (pioneered by Social Capital) measures growth efficiency by comparing revenue gains to revenue losses. It's a single number that tells you if your SaaS is healthy, stalling, or dying.

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

Numerator (Growth): All new revenue — new customers, upgrades, reactivations
Denominator (Loss): All lost revenue — churned customers, downgrades

How to Interpret

< 1.0
Dying — Revenue shrinking
1.0 - 2.0
Stalling — Growing but fragile
2.0 - 4.0
Healthy — Sustainable growth
> 4.0
Excellent — Hypergrowth

Example Calculation

Monthly MRR Movements
📈 Gains:
New customers: +$15,000
Expansion (upgrades): +$5,000
Resurrected (reactivations): +$2,000
Total Gains: $22,000

📉 Losses:
Churned customers: -$8,000
Contraction (downgrades): -$3,000
Total Losses: $11,000

Quick Ratio = $22K / $11K = 2.0
✅ Healthy, but not hypergrowth

Quick Ratio by Stage

Pre-PMF: Don't focus on Quick Ratio yet. Fix retention first.
Early Growth ($1M-$5M ARR): Target > 2.0. Below 1.5 means churn is killing you.
Scale ($5M-$20M ARR): Target > 3.0. Should have product-market fit + efficient acquisition.
Hypergrowth ($20M+ ARR): Target > 4.0. Expansion revenue should exceed churn.

Improving Your Quick Ratio

Increase numerator:

• Better lead generation (higher new MRR)
• Usage-based pricing (expansion MRR)
• Win-back campaigns (resurrected MRR)

Decrease denominator:

• Reduce churn (better onboarding, customer success)
• Prevent downgrades (usage alerts, plan optimization)
• Annual contracts (reduce monthly churn)
