Level versus movement
ARR is the size of the recurring base at a moment; net new ARR is how much that base moved over a period. Annual recurring revenue is a snapshot: the total recurring revenue you hold today. Net new ARR is the delta: new bookings plus expansion, minus churn and contraction, across the quarter or year. Confusing the two obscures the story, because a large ARR level says nothing about whether growth is accelerating, stalling, or being eaten from within.Net new ARR shows the quality of growth
| ARR | Net new ARR | |
|---|---|---|
| Type | Level (snapshot) | Movement (over a period) |
| Answers | How big is the base? | How fast is it growing, and how? |
| Components | Sum of all recurring revenue | New + expansion - churn - contraction |
| Hidden risk | Can rise while growth decays | Exposes the source of growth |
The efficient path is expansion
Net new ARR does not have to come from new sales. Reducing churn and contraction preserves more of the base, and growing existing accounts adds ARR without new acquisition cost. A company with strong net revenue retention generates net new ARR from expansion alone, which is more capital-efficient than buying every dollar of growth through new logos. Watching ARR and net new ARR together, the level and the movement, is how you tell durable growth from a number that looks healthy until the churn catches up.
Frequently Asked Questions
What is the difference between ARR and net new ARR?
ARR is the total recurring revenue you have right now, a snapshot level. Net new ARR is how much that total changed over a period: new bookings plus expansion, minus churn and contraction. One tells you how big the recurring base is; the other tells you how fast and in which direction it is moving.
Why track net new ARR separately from ARR?
Because total ARR can keep rising while the quality of growth deteriorates. Net new ARR breaks the movement into its parts, showing whether growth comes from new logos, expansion, or is being eaten by churn. A healthy ARR level built on shrinking net new ARR is a warning the total number hides.
How do you improve net new ARR without more new sales?
Through expansion and retention. Reducing churn and contraction keeps more of what you have, and growing existing accounts adds ARR without new acquisition. Strong net revenue retention means the base contributes net new ARR on its own, which is more efficient than buying all growth through new logos.
