SaaS viability score
Your SaaS viability score is a single 0–100 number that tells you whether your early-stage SaaS holds up financially. Enter your cash, MRR, growth, churn and burn to see your score and which of the five pillars — survival, unit economics, retention, growth, efficiency — are strong or weak.
Enter your cash and your monthly costs to continue.
How the score works
The score combines five pillars, weighted by how much they decide survival. Survival counts most (it is the metric that actually kills startups), followed by unit economics and retention. Each pillar is judged against healthy ranges for pre-seed/seed SaaS — the same ranges the full model uses — so the number never contradicts the detail. A business that runs out of cash before profitability is capped: it can never read as “on track”.
FAQ
What is a SaaS viability score?
A single 0–100 number that summarises whether an early-stage SaaS holds up financially. It weighs five pillars — survival (runway and default-alive), unit economics (LTV:CAC and payback), retention (churn and net revenue retention), growth, and capital efficiency — against pre-seed/seed SaaS ranges. It is orientative by stage, not an absolute grade.
How is the viability score calculated?
Each pillar is scored against healthy ranges for early-stage SaaS and combined with weights — survival counts most (35%), then unit economics and retention (20% each), growth (15%) and efficiency (10%). A business that runs out of cash before profitability is capped so it can never read as “on track”, no matter how good the other pillars look.
What is a good viability score?
Above 80 is strong, 60–80 is on track, 40–60 is fragile and below 40 is at risk. Early-stage numbers are noisy, so read the score by stage: a pre-seed startup that is default-alive with healthy churn and unit economics is doing well even if growth is modest.
Is the free score accurate?
It is a quick estimate from seven inputs. The full model recomputes the same score from your real cost structure, headcount, gross-margin breakdown and funding rounds, and shows exactly what to change to lift each weak pillar.
