What it is
Revenue mix (interchange/lending/sub) tracks what percentage of total revenue comes from each of the three principal consumer fintech monetization lines. The formula is each revenue line divided by total revenue, expressed as a percentage.
How to calculate it
For each revenue category — interchange fees, net interest / lending income, and subscription or premium plan fees — divide the period revenue by total revenue and multiply by 100. The three shares should sum to 100% (plus any residual other revenue).
Why it matters
Revenue mix determines a neobank's risk profile, margin structure, and regulatory exposure. Interchange-heavy models have high volume requirements and Durbin risk. Lending-led models carry credit risk and capital requirements. Subscription models are more predictable but harder to scale without strong premium value. Tracking mix over time reveals strategic drift or intentional product evolution.
Benchmarks & pitfalls
Sacra and BCG (2023) identify three archetypal paths for consumer fintech revenue mix: subscription-led (exemplified by Revolut), lending-led (Nubank), and interchange-led (Chime). No specific percentage splits are provided in the source material — the benchmark is qualitative and directional, reflecting strategic archetypes rather than a numeric industry distribution. Companies often blend these paths over time, so mix should be tracked quarterly. This is a directional framework, not a rigorous published study with numeric benchmarks.
