MRR is total monthly recurring revenue, while churn rate is the percentage of customers lost in a period divided by total customers at period start.
Calculating B2B SaaS metrics is crucial for understanding business health and growth trajectory. Here are the essential formulas:
Monthly Recurring Revenue (MRR): Sum all subscription revenue normalized to a monthly amount. For annual plans, divide by 12. Track New MRR, Expansion MRR, and Churned MRR separately.
Churn Rate: (Customers lost during period / Customers at start of period) × 100. Calculate both customer churn and revenue churn, as losing high-value customers impacts revenue churn more significantly.
Customer Acquisition Cost (CAC): Total sales and marketing expenses divided by new customers acquired in the same period.
Lifetime Value (LTV): Average revenue per user (ARPU) divided by churn rate, or more precisely: (ARPU × Gross Margin %) / Monthly Churn Rate.
LTV/CAC Ratio: Should typically be 3:1 or higher for healthy unit economics.
Annual Recurring Revenue (ARR): MRR × 12, useful for tracking yearly growth trends.
Laurens De Jonghe from Open recommends tracking these metrics monthly and segmenting by customer cohorts to identify patterns. Use tools like ChartMogul or ProfitWell for automated tracking, but understand the underlying calculations to make informed decisions.
