What is SaaS Health Score?
A SaaS health check evaluates your business across MRR growth, churn rate, LTV:CAC ratio, net revenue retention, and operational runway.
The Formula
Score = (ฮฃ Category Scores รท Number of Categories) ร 100
Worked Example
A SaaS company: 10% MRR growth, 4% monthly churn, 2.8:1 LTV:CAC, 98% NRR, 15 months runway.
- Growth: 10/15 = 67/100
- Churn: 3/4 = 75/100 (lower is better, inverted)
- LTV:CAC: 2.8/4.0 = 70/100
- NRR: 98/110 = 89/100
- Runway: 15/18 = 83/100
- Overall = (67 + 75 + 70 + 89 + 83) รท 500 ร 100 = 77%
๐ SaaS health is 77%, decent retention and runway but growth and unit economics need improvement.
Why This Matters
Investor readiness
VCs evaluate these exact metrics. A health score above 80% significantly improves funding prospects and terms. OpenView Partners data from 2024 shows that SaaS companies with top-quartile health scores across MRR growth, churn, and LTV:CAC raise their next round at valuations 30-50% above the stage median.
Operational focus
The health check identifies the single metric with the most leverage for overall improvement. According to Bessemer Venture Partners' SaaS framework, fixing the lowest-scoring KPI in an otherwise healthy business produces an average 22% improvement in overall health score, the highest return on strategic effort of any single intervention.
Early warning system
Declining health scores predict problems 3-6 months before they hit revenue. Monitor monthly. Pacific Crest SaaS Survey data shows that companies monitoring composite health scores monthly detect retention problems an average of 4.2 months earlier than companies relying on revenue reports alone, providing enough time to intervene before problems compound.
Common Mistakes
โ Ignoring net revenue retention
NRR below 100% means you are shrinking even without churn. Expansion revenue must exceed contraction. OpenView data shows SaaS companies with NRR above 110% grow 2.4x faster than those with NRR between 90-100%, because existing customer expansion compounds on top of new customer acquisition rather than merely offsetting churn losses.
โ Celebrating gross metrics
$1M ARR means nothing with $900K in annual churn. Net metrics tell the real story. ProfitWell research shows that 43% of SaaS companies that failed despite reaching $1M ARR had gross churn rates above 60% annually, meaning most revenue was replaced rather than retained, masking fundamental business model problems until it was too late.
โ Not benchmarking by stage
Seed metrics look different from Series B. Compare against your stage-specific peer group. Andreessen Horowitz research confirms that applying Series B efficiency benchmarks to seed-stage companies causes founders to over-optimize for unit economics too early, cutting growth investment and arriving at Series A with metrics that are efficient but insufficient to justify a meaningful round.
