SaaS Growth Health Calculator
Enter your cash position, revenue growth, and MRR movement once, and see the four numbers that together answer whether a SaaS business is growing sustainably or just growing fast.
Cash Position
Growth & Profitability
Revenue Retention
Results
Burn Rate
Runway
Rule of 40
Net Revenue Retention
What This Means
Burning $40000 a month leaves about 14.0 months of runway at the current pace. Revenue is growing 30.0% with a 15.0% profit margin, for a Rule of 40 score of 45, above the healthy threshold. Net revenue retention is 101.0%, meaning the existing customer base is growing even before any new sales.
Why It Matters
Burn rate and runway answer how much time is left. Rule of 40 and net revenue retention answer whether growth is actually healthy. Checked separately, a company can look fine on any one of these while the full picture, cash running out in 8 months while retention quietly erodes, only shows up when all four are read together.
Example
A company starts the month with $600,000 in cash and ends with $560,000, is growing revenue 30% a year with a 15% profit margin, and its MRR moved from $100,000 to $105,000 after $8,000 in expansion, $3,000 in downgrades, and $4,000 in churn. Burn rate is $40,000 a month, giving 14 months of runway. Rule of 40 comes out to 45, above the healthy threshold. Net revenue retention is 101%, meaning the existing base is growing even before new sales, a company with real time on the clock and fundamentally sound growth.
