FAQ

SaaS metrics questions answered

What's the most important SaaS metric?+
For early-stage startups: Runway. For growth-stage: LTV:CAC ratio and NRR (Net Revenue Retention). For public companies: NRR and Gross Margin. Investors prioritize LTV:CAC > 3x and NRR > 100%.
What's a healthy LTV:CAC ratio?+
Target LTV:CAC > 3x. Below 3x means you're spending too much to acquire customers. Between 3x-5x is healthy. Above 5x means you may be under-investing in growth.
What's good monthly churn for SaaS?+
B2B SaaS: 1-2% monthly churn is healthy. B2C: 3-5% is typical. Under 1% is exceptional. Enterprise SaaS can be under 0.5%. Reducing churn by 1% can double LTV.
How do I calculate NRR?+
NRR = (Starting MRR + Expansion - Churn - Contraction) / Starting MRR. Top SaaS companies have NRR > 120%, meaning existing customers spend 20%+ more over time.
What's a good gross margin for SaaS?+
Target >75% gross margin. Top SaaS companies achieve 80-85%. Lower margins indicate high hosting costs, support costs, or third-party fees.
How much runway should a startup have?+
Best practice: 18-24 months of runway after a raise. Start fundraising when you have 6-9 months left. Less than 6 months is "danger zone."
What's CAC payback period?+
Payback period = CAC / (Monthly ARPU × Gross Margin). Best-in-class SaaS: <12 months. Acceptable: 12-18 months. Concerning: >24 months.
Are these calculators accurate for my business?+
Yes — all calculators use standard SaaS formulas. For best results, use actual financial data. Our tools are used by thousands of SaaS companies for board reporting and investor updates.
