Understanding SaaS MRR Metrics
MRR (Monthly Recurring Revenue) = Customers × ARPU. It's the predictable revenue a SaaS business earns each month from subscriptions.
Net New MRR = New MRR + Expansion MRR − Churned MRR. Positive net new MRR means the business is growing.
LTV (Lifetime Value) = ARPU ÷ Monthly Churn Rate. It estimates how much revenue an average customer generates before they cancel.
Healthy SaaS benchmarks: monthly churn under 5% (ideally 2-3%), LTV/CAC ratio above 3:1, and positive net new MRR.
Frequently Asked Questions
MRR (Monthly Recurring Revenue) is the predictable revenue a subscription business earns each month. It equals the number of paying customers multiplied by the average revenue per user (ARPU).
For B2B SaaS, 2-5% monthly churn is typical. Under 2% is excellent. B2C SaaS often sees higher churn (5-10%). Enterprise SaaS with annual contracts may have less than 1% monthly churn.
NRR measures revenue from existing customers over time, including expansions and contractions. NRR above 100% means expansion revenue exceeds churn — a sign of a very healthy SaaS business.
LTV = ARPU / Monthly Churn Rate. For example, $49 ARPU with 3% churn = $1,633 LTV. A common target is LTV/CAC ratio of 3:1 or higher.
