Key SaaS metrics include MRR, CAC, LTV, and churn rate, calculated using subscription revenue, acquisition costs, and customer behavior data.
Essential SaaS metrics provide insights into business health, growth trajectory, and profitability potential. Accurate calculations enable data-driven decisions and investor communication.
Monthly Recurring Revenue (MRR) = Sum of all monthly subscription values. For annual plans, divide by 12. Track new MRR, expansion MRR, contraction MRR, and churned MRR separately.
Customer Acquisition Cost (CAC) = Total sales and marketing expenses ÷ Number of new customers acquired in the same period. Include salaries, advertising, tools, and overhead costs.
Customer Lifetime Value (LTV) = (Average Revenue Per User × Gross Margin %) ÷ Churn Rate. Alternatively: ARPU × Average customer lifespan × Gross margin.
Churn Rate = (Customers lost during period ÷ Customers at start of period) × 100. Calculate both customer churn and revenue churn monthly.
LTV:CAC Ratio should exceed 3:1 for healthy unit economics. Payback Period = CAC ÷ (Monthly ARPU × Gross Margin %) indicates how long to recover acquisition costs.
Net Revenue Retention = (Starting MRR + Expansion MRR - Contraction MRR - Churned MRR) ÷ Starting MRR × 100. Values above 100% indicate growth from existing customers.
Regular tracking using tools like ChartMogul or building custom dashboards ensures accurate monitoring. As Joni Van Langenhoven notes, consistent metric calculation methodologies are crucial for trend analysis. For personalized guidance, consult a SaaS Business Models specialist on TinRate.
