Closing Contracted Annual Recurring Revenue

What it measures

The point-in-time sum of every signed contract's annualized recurring value as of the last day of the reporting period, including deals closed but not yet live. The closing balance is calculated as the opening balance plus all inflows (new contracts signed and expansion amendments effective during the period) minus all outflows (customer downgrades and cancellations effective during the period). One-time fees, services, and usage overages are excluded — only committed annual run-rate counts.

Why it matters

Closing CARR is your end-of-period revenue snapshot and the starting point for next period's P&L forecast. Because CARR counts all signed contracts regardless of activation status, it represents the total revenue your team has locked in and can expect to realize over the next 12 months. The waterfall components tell you whether growth came from new logos or expansion, or whether it was held back by churn — essential diagnostic data for board updates, quarterly guidance, and the Sales and CS playbooks.

How to read it

Always read Closing CARR as a period-over-period trend, never as a single month in isolation. If Closing CARR is growing each period, your bookings machine is winning; if flat or declining, you have a revenue crisis. Compare Closing CARR to Opening CARR to understand the net movement — a healthy period shows strong inflows (New + Upsell) outrunning outflows (Downsell + Churn). Also track Closing CARR versus live ARR: the gap is your signed-but-not-live backlog. A widening gap suggests onboarding or activation delays; a stable gap suggests a healthy pipeline-to-activation engine.

Watch-outs

• Mixing up Closing CARR with cash collected. A healthy Closing CARR can sit alongside weak cash flow if contracts are signed but not yet invoiced, or customers are on long payment terms. CARR is contractually committed revenue, not cash in the bank.
• Forgetting to annualize multi-year deals. A three-year contract for $300K is $100K of Closing CARR, not $300K. Always normalize to the one-year run-rate or closing CARR will spike on mega-deals and become impossible to trend month over month.
• Ignoring the components. A flat Closing CARR month over month can hide churn: $500K of new bookings offset by $500K of churn is a crisis in disguise. Always review New, Upsell, Downsell, and Churned CARR to diagnose what moved.
• Not tracking the CARR-to-ARR gap. Closing CARR minus live ARR is your pre-activation backlog. If this gap is widening faster than your typical onboarding cycle, you have an activation bottleneck. If it collapses suddenly, you have a large cohort activating — both matter for cash and headcount planning.
