How to calculate key SaaS metrics like ARR and churn rate?

Calculate ARR by multiplying monthly recurring revenue by 12, and churn rate by dividing customers lost in a period by total customers at period start.

Understanding and calculating key SaaS metrics is crucial for measuring business health and growth. Here are the essential calculations:

Annual Recurring Revenue (ARR): Multiply your Monthly Recurring Revenue (MRR) by 12. For example, if your MRR is $50,000, your ARR is $600,000. ARR represents predictable revenue from subscriptions over a year.

Monthly Recurring Revenue (MRR): Sum all recurring subscription revenue normalized to a monthly amount. Include upgrades and exclude one-time fees.

Churn Rate: Calculate customer churn by dividing customers lost during a period by total customers at the beginning of that period. If you start with 100 customers and lose 5, your churn rate is 5%. Revenue churn follows the same formula but uses revenue instead of customer count.

Customer Acquisition Cost (CAC): Divide total sales and marketing expenses by the number of new customers acquired in the same period.

Lifetime Value (LTV): Calculate as (Average Revenue Per User × Gross Margin) ÷ Churn Rate. A healthy LTV:CAC ratio is typically 3:1 or higher.

Net Revenue Retention (NRR): Measure revenue retention from existing customers, including upgrades and downgrades. Above 100% indicates expansion revenue exceeds churn.

Regularly tracking these metrics helps identify trends, optimize pricing, and make data-driven decisions about growth strategies.
