Unittransactions per active user per month
Triangular grid where rows are signup cohorts and columns are months. Watch average transactions per active user growing over time. Build by counting transactions per user per cohort per month. Example: Oct 25 cohort 4.2 txns/mo at M5; Mar 26 cohort 5.1 at M0 (new cohort more engaged).
Benchmarks
| Bottom 30% | Median | Top 30% |
|---|---|---|
| fewer than 2 transactions per active user per month by month 12, the secondary-account pattern | 4 to 8 transactions per active user per month by month 12 | 15 or more card and account transactions per active user per month by month 12, the level at which a fintech account behaves as a primary account |
Consumer fintech and neobank accounts, per active user rather than per registered user, global with a US, UK and LatAm weighting, 2024 to 2026. Excludes internal transfers and balance checks. · The single biggest definitional trap is the denominator. Nubank reports against a monthly activity rate of 83%, so per-active figures there are close to per-customer figures; a wallet reporting against registered users will look three to five times worse for identical behaviour. State which denominator the chart uses on the chart itself. The top30 anchor is taken from Chime's disclosed threshold for a primary account relationship, 15 or more card purchases in a calendar month, which is a product definition rather than a survey median, so treat it as a bar to clear rather than a percentile. PayPal's own transaction intensity is computed here from filed figures (18.6bn transactions across nine months of 2025 against 438m active accounts, roughly 4.7 per active account per month) rather than reported directly as a per-user rate.
Category split omitted: No two independent Tier 1 or Tier 2 sources publish transactions per active user split by fintech sub-model on a comparable definition; the available figures are single-company disclosures on differing denominators.
When it looks bad
Every cohort line starts at a similar level and then flattens within two or three months instead of climbing, so the whole chart is a set of parallel horizontal lines sitting low, meaning no cohort ever graduates from occasional use to habitual use.
The month-1 cohort does 3.1 transactions per active user, month-6 does 3.3, month-18 does 3.4. Eighteen months of product work has bought 0.3 transactions per user per month.
What to do about it
- Drive direct deposit or salary switching as the single activation event, since it is the mechanism that converts occasional to habitual use. Chime's own primary relationship definition treats one qualifying direct deposit of USD 200 or more as equivalent to 15 card purchases in a month, which tells you which lever the disclosure treats as load-bearing (Chime S-1/A).
- Move the card to top-of-wallet with a category-limited rebate on two or three high-frequency merchant categories rather than a flat cashback. Flat cashback lifts spend per transaction; category caps lift transaction count, which is what this chart measures.
- Instrument the web-to-app handoff with deep links into the specific in-app destination rather than the home screen. Web-to-app drives 41.8% of owned media conversions in Western European finance apps, and a user who has to restart the journey after install contributes zero transactions (AppsFlyer with Sensor Tower, 2026).
- Add a recurring bill or subscription rail. Recurring transactions convert a cohort's transaction count from a decaying curve to a floor, and they do not need re-acquisition each month.
