Definition

MetricShare of an account's expansion ARR realised by tenure month

Unit% of the account's cumulative three-year expansion ARR, distributed by month of tenure

Histogram of months from initial close to first expansion. Build from upgrade events with original-close timestamps. Identifies the natural expansion window to design CSM motion around. Example: median 8 months; long tail at 24+ months (most expansion happens in year one).

Customer success manager. Owner of retention and expansion for a book of accounts.

B2B SaaS, expansion ARR by tenure month for accounts surviving three years, gross of contraction. Distribution shape rather than level; the level is set by card 176. · No Tier 1 or Tier 2 source publishes an expansion-by-tenure-month distribution, so the percentile figures above are inferred from directional findings rather than read off a dataset, and they should be used as a hypothesis to test against your own data rather than as a target. The inference rests on three things. ChartMogul states directly that new customers expand most during year one as they ramp usage and complete onboarding, and that churn rises in year two. Paddle's ProfitWell data shows upsell revenue recovering its cost inside a single quarter against more than a year for new customer acquisition, which is only possible if expansion lands early. Benchmarkit shows expansion ARR share rising with company size, which is a cross-sectional finding about company maturity and not about account tenure, so it does not support the shape and is included only to prevent it being misread as support. Treat this card as directional. If your own distribution puts most expansion at month 12 and month 24, that is a renewal-negotiation motion rather than a usage-driven one, which is a real finding rather than a failure.

Category split omitted: No two independent Tier 1 or Tier 2 sources publish expansion timing split by segment, pricing model or ACV band; the underlying distribution is not published at all.

When it looks bad

The distribution is a pair of spikes at month 12 and month 24 with a flat floor between them, meaning expansion only happens when a contract is open and nothing in the product or the CS motion creates a reason to buy more mid-term.

Of $840K of expansion across the cohort, $610K lands in the two months surrounding a renewal date and $230K across the other twenty-two months. Mid-term expansion runs at roughly $10K a month against $305K in a renewal month.

What to do about it

  • Move expansion triggers off the calendar and onto usage. If the distribution spikes only at renewal, the packaging has no mid-term upgrade path, and adding a usage-linked line or a seat threshold converts a negotiation into a purchase. Benchmarkit found hybrid subscription plus usage pricing carries a 110% median NRR against lower figures for either model alone.
  • Front-load the expansion conversation into onboarding for accounts where year one is the natural window. ChartMogul's finding that expansion concentrates in year one while churn rises in year two means the account is most expandable exactly when the CS team is most focused on getting it live.
  • Where expansion sits almost entirely at renewal and GRR is strong, do not treat this as a defect. Verify against the GRR to NRR gap first: SaaS Capital treats 8 to 20 points as normal, and a company inside that band with renewal-concentrated expansion is running a legitimate annual-uplift motion.
  • Track expansion timing separately for accounts that later churned. Expansion that lands in month 22 on an account that leaves at month 26 is usually a discount-for-term trade rather than value capture, and netting it out changes what the distribution is telling you.

ChartMogulThe SaaS Retention Report: The New Normal For SaaS · 2024 · n=2,500+ SaaS businesses, aggregated anonymised billing data, H1 2021 to H1 2024 Expansion drives up to 40% of growth for companies at $15M to $30M+ ARR, versus 30% in early 2021. Even the top quartile at $15M to $30M+ ARR failed to reach 100% NRR in 2024. Companies at or above 100% NRR draw over half of added revenue from expansion; companies below 60% NRR draw 70% from new business and 15% from expansion. New customers expand most during year one as they ramp usage, and churn tends to rise in year two.
