Ehsan's Analysis
FinTech Quick Ratio is harder to calculate than SaaS because "new revenue" and "churned revenue" are not cleanly defined for transaction-based businesses. Adaptation: (new active customers × avg monthly revenue) + (existing customer revenue growth) ÷ (lost customer revenue + declining customer revenue). By this measure, most FinTech companies have Quick Ratios of 1.5-2.5 — lower than SaaS because free-tier churn is high and per-customer revenue is low. The FinTech companies with Quick Ratio above 4 — Stripe, Adyen, Square — benefit from "organic expansion" where merchant transaction growth automatically increases revenue without acquisition spend. This is the FinTech version of net negative churn, and it is only possible with usage-based revenue models. FinTech companies with subscription-only revenue (Revolut Premium, Bloomberg Terminal) have SaaS-like Quick Ratios of 3-5. Those with transaction-only revenue are more volatile, swinging between 1.5 and 4 based on market conditions.
