Net new ARR is the annualized recurring revenue gained from new customers minus revenue lost to churn, measured over a specific period.
Net new ARR is the annualized recurring revenue gained from new customers minus revenue lost to churn, measured over a specific period. It's the single number that tells you whether your business is actually growing: customers acquired minus customers lost, all in annual dollars.
On a real call, this comes up when you're forecasting quarter-end revenue or explaining why a big win still didn't move the needle. A company closes two $50K ARR deals but churned three $40K customers. That's $100K in new ARR minus $120K in churn, for a net new ARR of negative $20K. You grew your customer count but shrank your revenue base—a red flag the board will catch immediately.
People confuse net new ARR with related concepts because they all touch revenue, but they measure different things:
| Term | What it includes | Why it matters |
|---|---|---|
| Net new ARR | New customer ARR minus churn | Tells you if your revenue base is actually growing |
| Gross new ARR | Only new customers, ignores churn | Shows sales productivity but hides retention problems |
| Net Dollar Retention | Expansion revenue, upsell, cross-sell within installed base | Shows how well you monetize existing customers |
| Annual Contract Value | Total annual value of one deal, regardless of whether it's new or renewal | Describes deal size, not portfolio health |
| Expansion revenue | Revenue from selling more to customers you already have | Part of net dollar retention, separate from net new ARR |
Net new ARR is the only metric that forces you to account for both sides of the growth equation. A sales team can hit quota on gross new ARR while the company loses money to churn.
Your forecast matters if it predicts actual revenue. When you commit to a number at deal stage, you're implicitly committing to what that customer's net impact will be on the business. A $100K ACV deal looks identical in the pipeline whether the customer will stay three years or three months—but the net new ARR impact is vastly different.
Account executives who own existing customers (whether through expansion or retention) often feel disconnected from pipeline metrics. Net new ARR forces alignment: if you close expansion deals or prevent churn, that shows up in the number that matters most to the CFO. Sales leaders use net new ARR to decide whether to hire hunters (who generate gross new ARR) or farmers (who protect net new ARR through retention and expansion).
Teams treat net new ARR as a lagging indicator—something you calculate after the quarter closes. But for forecasting accuracy, you need to predict churn month by month within your quarter. If you have $2M in deals closing this quarter but $800K in customers who are likely to churn, your honest net new ARR forecast is $1.2M, not $2M. Many teams forecast only the new side and get surprised when churn hits.
Gross new ARR counts only revenue from new customers. Net new ARR subtracts churn. If you close $100K in new ARR but lose $30K to churn, gross new ARR is $100K and net new ARR is $70K. Net new tells you what actually stuck.
If your quota measures bookings or gross new ARR (new customers only), you can hit it while losing more revenue to churn than you bring in. You grew headcount but lost portfolio value. This is why mature SaaS companies often weight retention into quota.
Look at historical churn patterns by cohort and segment. If you know that customers from a certain source or use case churn at 5% per month, apply that to your installed base. Your net new forecast is new bookings minus predicted churn for the period.
No. Net new ARR measures new revenue minus churn across your entire book. Net dollar retention measures how much revenue you keep and grow from the customers you had at the start of the period—it includes expansion but excludes new logos.
