FAQ

MRR (Monthly Recurring Revenue) is the predictable revenue your business earns each month from active subscriptions. ARR is simply MRR × 12 — the standard for annual planning, fundraising, and benchmarking.

For B2B SaaS, monthly churn below 1% is healthy. Best-in-class is 0.5% or less. B2C tolerates 2–3%. Above 3% monthly churn is a serious retention problem that will stunt growth.

An LTV:CAC ratio above 3 is the industry benchmark. Below 1 means losing money on each customer. 1–3 is marginal. Above 5 may indicate under-investment in growth.
