Key Concepts
Customer Lifetime Value (LTV)
Customer Lifetime Value measures the total revenue a business can expect from a single customer account throughout their entire relationship. LTV is calculated by multiplying average revenue per account by gross margin and customer lifespan. This metric is foundational for SaaS economics because it determines how much you can afford to spend acquiring customers (CAC) while remaining profitable. High LTV indicates strong product-market fit, effective retention strategies, and successful expansion revenue programs.

Churn rate measures the percentage of customers or revenue lost over a given period, typically monthly or annually. Customer churn counts accounts lost, while revenue churn captures the dollar impact including downgrades. Even small improvements in churn create compounding effects on growth—reducing churn preserves existing revenue, extends customer lifetimes, and improves LTV. High churn often signals product-market fit issues, onboarding problems, or competitive pressure that require strategic intervention.

Net Revenue Retention measures how much revenue you retain and expand from existing customers, expressed as a percentage. NRR above 100% means expansion revenue (upgrades, seat additions, cross-sells) exceeds contraction and churn. Strong SaaS companies target 110-130% NRR, meaning their existing customer base grows even without new acquisition. NRR is considered one of the most important SaaS health metrics because it demonstrates product stickiness and customer success effectiveness.

CAC Payback Period measures how many months it takes to recover customer acquisition costs through gross margin contribution. Shorter payback periods indicate more efficient growth and faster return to profitability on each customer. The calculation divides fully-loaded CAC by monthly gross margin per customer. Most SaaS companies target 12-18 month payback for SMB and 18-24 months for enterprise. Payback period helps determine sustainable growth rates and investment levels in sales and marketing.

LTV CAC ratio compares customer lifetime value to customer acquisition cost, indicating unit economics efficiency. A ratio of 3:1 or higher is considered healthy for most SaaS businesses—meaning you earn $3 in lifetime value for every $1 spent acquiring a customer. Ratios below 1:1 indicate unsustainable growth where you're spending more to acquire customers than they generate. This metric helps calibrate sales and marketing spend relative to customer quality and retention.
