How is Monthly Recurring Revenue (MRR) calculated?

MRR = Customers × ARPU (Average Revenue Per User). For subscription businesses, this represents the predictable monthly revenue. The calculator shows MRR, including new MRR, expansion MRR (upgrades), contraction MRR (downgrades), and churn MRR (cancellations).

What's the difference between MRR and ARR?

MRR is monthly recurring revenue. ARR (Annual Recurring Revenue) = MRR × 12. For annual contracts, ARR is the primary metric. The calculator shows both, helping you understand your revenue scale.

How is churn rate calculated?

Churn Rate = (Lost Customers / Total Customers) × 100. For example, 1,000 customers losing 50 = 5% churn. The calculator shows both customer churn and revenue churn (lost revenue percentage), helping you understand the full impact.

What's the difference between customer churn and revenue churn?

Customer churn is percentage of customers lost. Revenue churn is percentage of revenue lost. Revenue churn can differ from customer churn if lost customers had different revenue levels. The calculator shows both, as revenue churn is more important for profitability.

What is Net Revenue Retention (NRR)?

NRR = (End MRR - Expansion MRR) / Start MRR. It shows revenue retention including expansion. A NRR above 100% means you're growing revenue from existing customers. The calculator shows NRR and benchmarks for your industry.

What are good SaaS metric benchmarks?

Growth Stage: MRR growth 10-20% monthly, Churn 3-5%, LTV:CAC 4:1. Mature: MRR growth 5-10%, Churn 1-3%, LTV:CAC 5:1. The calculator includes industry-specific benchmarks to help you evaluate your performance.

How does the CAC payback period work in SaaS?

Payback period = CAC / (ARPU × Gross Margin %). It shows how long it takes to recoup acquisition costs. SaaS businesses target 6-12 months payback. The calculator shows your payback period and suggests improvements.

What's the relationship between churn and growth in SaaS?

Growth rate = Net New MRR / Start MRR. Churn slows growth. For example, 10% new customer growth with 5% churn yields 5% net growth. The calculator shows this relationship, helping you understand the impact of churn reduction.

How do I calculate customer lifetime value in SaaS?

LTV = ARPU × (1 / Churn Rate). For example, $50 ARPU with 5% churn = $1,000 LTV. The calculator shows LTV and the LTV:CAC ratio, helping you evaluate customer economics.

What's the difference between subscription revenue and one-time revenue?

Subscription revenue is recurring (monthly/annually). One-time revenue is non-recurring (setup fees, consulting). The calculator separates these, showing MRR for recurring revenue and total revenue for the business.
