A board slide says ARRARRAnnual Recurring Revenue (ARR) is the normalized, predictable revenue a subscription business expects to earn from active contracts over a single year.View full definition → grew 40% year over year. Nobody claps until someone asks: how much of that came from new customers versus existing ones paying more? That question separates a durable business from one quietly leaking customers while sales scrambles to backfill the hole with new logos. The answer lives in an bridge.

The bridge (also called an ARRARRAnnual Recurring Revenue (ARR) is the normalized, predictable revenue a subscription business expects to earn from active contracts over a single year.View full definition → waterfall) decomposes the change into components.

As of recent industry surveys (treat as estimates, methodologies vary by source):
Regional nuance: European SaaS benchmarks (commonly referenced via reports from firms like Dealroom or local VCs) tend to skew slightly lower on average NRRNRRNet Revenue Retention measures the percentage of recurring revenue retained and grown from existing customers over a period, including upsell and expansion, net of downgrades and churn.View full definition → than top US comparables, partly reflecting smaller average contract values and more price-sensitive SMB (small and medium business) segmentssegmentsDividing a market into distinct groups of customers who share similar needs, characteristics or behaviours, so each group can be served with a tailored approach.View full definition → in fragmented markets.

Gross Revenue Retention (GRR) is the stricter cousin: same formula as NRRNRRNet Revenue Retention measures the percentage of recurring revenue retained and grown from existing customers over a period, including upsell and expansion, net of downgrades and churn.View full definition → but capping expansion at zero, so it only measures what you kept, not what you grew.
GRR = (Starting ARRARRAnnual Recurring Revenue (ARR) is the normalized, predictable revenue a subscription business expects to earn from active contracts over a single year.View full definition → − Contraction − Churn) / Starting ARRARRAnnual Recurring Revenue (ARR) is the normalized, predictable revenue a subscription business expects to earn from active contracts over a single year.View full definition →
GRR = (10.0 − 0.3 − 0.5) / 10.0 = 9.2 / 10.0 = 92%
GRR above roughly 90% is commonly cited as healthy for enterprise SaaS; anything meaningfully below that suggests a product or customer-fit problem, not just a pricing opportunity.
When you see an ARRARRAnnual Recurring Revenue (ARR) is the normalized, predictable revenue a subscription business expects to earn from active contracts over a single year.View full definition → bridge, ask three questions:
1. What share of gross new ARR came from expansion versus new logos? Rising expansion share usually signals product stickiness and cross-sell success.
2. Is churn concentrated or broad? A single large enterprise account leaving is a different story than dozens of small SMB accounts churning, the latter often points to onboarding or product-market fitproduct-market fitThe moment your product genuinely solves a real problem for a well-defined market, so users retain, refer and pay willingly.View full definition → issues.
3. Is contraction increasing over time? Rising contraction (downgrades) often precedes outright churn by a quarter or two, it's a leading indicator worth tracking separately from cancellations.
Knowledge check
1. Two companies report identical headline ARR growth for the quarter. Why might a board still consider one company's growth far riskier than the other's?
2. A company's ARR bridge shows large New ARR but also large Churned ARR each quarter. What does this pattern most likely indicate?
3. Why do analysts distinguish Contraction ARR from Churned ARR rather than lumping both into a single 'revenue lost' bucket?
4. Select ALL correct answers about what the ARR bridge is designed to reveal that a single ending ARR figure cannot.

Even a basic spreadsheet bridge clarifies the story. The logic in plain terms:
ending_arr = starting_arr + new_arr + expansion_arr - contraction_arr - churned_arr
nrr = (starting_arr + expansion_arr - contraction_arr - churned_arr) / starting_arr
grr = (starting_arr - contraction_arr - churned_arr) / starting_arr
new_logo_dependency = new_arr / (new_arr + expansion_arr)That last line, new logo dependency, is a useful gut-check metric even though it's not standardized industry vocabulary: the higher it is, the more growth relies on constantly refilling the top of the funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.View full definition → rather than deepening existing relationships.
