How does revenue per user evolve?
№ 103 · ARPU by cohort
Definition
MetricMonthly revenue per active user, tracked by signup cohort and tenure
UnitUSD revenue per active user per month
Triangular structure showing revenue per user, by cohort by month. Build by dividing total revenue by active user count per cohort per month. Watch newer cohorts entering at higher ARPU than older cohorts (monetization improving). Example: Oct 25 cohort $8.40 at M5; Mar 26 cohort $9.20 at M0.
- ARPU
- Average revenue per user. Revenue in a period divided by active users in that period.
Benchmarks
| Bottom 30% | Median | Top 30% |
|---|---|---|
| Blended book below USD 4 per active user per month, the level at which the account is a secondary spending account rather than a banking relationship | Blended book at USD 12 to USD 15 per active user per month, with year-one cohorts at USD 4 to USD 8 | Mature cohorts (5 years or more of tenure) at USD 25 to USD 30 per active user per month, roughly 1.8x to 2.5x the blended book |
Consumer fintech and digital banks, revenue per monthly active user, LatAm and US weighted, 2024 to 2026. Nubank ARPAC is the anchor for the cohort ramp because it is the only large fintech that publishes ARPU by tenure band. · Sources disagree because they measure different populations. Nubank's USD 15 is per monthly active customer against an 83% activity rate. Chime's USD 251 to USD 257 is annual revenue per active member, which converts to roughly USD 21 per month, and Chime's member base skews to direct-deposit primary relationships. The Accenture figure of USD 45 per year is per registered user across all neobanks including dormant accounts, which is why it looks an order of magnitude lower. Convert everything to monthly per active before putting it on one chart. The USD 350 figure quoted for traditional retail banks is annual and includes lending and wealth revenue that most fintechs do not carry.
| Category | Bottom 30% | Median | Top 30% |
|---|---|---|---|
| Credit-led digital bank (LatAm), blended monthly ARPU | USD 11 and below | USD 13 to 15 | USD 15 and above |
| Credit-led digital bank (LatAm), cohorts with 8 or more years of tenure | about USD 25 | about USD 26 to 27 | USD 27 and above |
| Interchange-led US neobank, monthly ARPU per active member | not separately disclosed | about USD 21 | about USD 21 |
| P2P wallet, annualised gross profit per monthly transacting active | not separately disclosed | about USD 87 to 94 per year | about USD 94 per year |
When it looks bad
The cohort lines are stacked in the wrong order, with newer cohorts sitting below older ones at the same tenure point, so the chart shows each successive vintage monetising worse than the one before it at month 6, month 12 and month 18.
The 2024 cohort reached USD 9.40 per active user by month 12. The 2025 cohort reached USD 7.10 at the same point and the 2026 cohort is tracking to USD 6.20. Blended ARPU is still rising only because the old cohorts are large.
What to do about it
- Sequence a second revenue line into the first 90 days rather than the second year. Nubank's blended ARPAC rose from USD 11.1 to USD 15.0 in four quarters while activity rate stayed flat at 83%, which means the gain came from products per customer, not from more customers being active (Nu Holdings Q4 2025).
- Split the chart by acquisition channel before optimising the product. Newer cohorts monetising worse at the same tenure is usually a channel-mix problem, and paid social cohorts in finance typically carry lower intent than referral cohorts.
- Build the referral loop off product depth rather than off a standalone bonus. Chime disclosed that members using six or more products referred 1.6x as many friends as the average member and generated 1.8x the ARPU, so depth and acquisition are the same lever (Chime S-1/A and associated filings analysis).
- Hold cost to serve flat while ARPU climbs and report the two on the same axis. Nubank carried cost to serve at USD 0.80 per active customer per month against USD 15 of ARPAC, an 18x gross spread that is the actual reason the cohort ramp is worth chasing (Nu Holdings Q4 2025).
