Explore case outcomes and model limitations." url: https://marginfix.ai/industries/fintech/ lastmod: 2026-11-11 --- Industry · Marketing & margin audit # Fintech marketing audit: published findings and scope Separate acquisition from risk adjusted contribution, fraud, servicing and retention. Lending, payments and wealth businesses have different economics; the shared model does not capture those differences. 7 published cases $540k sum of annual case figures $83k lower median case figure / yr 7 days lower median time to findings The 7 published Fintech case highlights sum to $540k in annual figures, with a lower median of $83k. Each case explains its own outcome; the sum does not establish realized cash recovery. ## What the Fintech figures mean 7 published Fintech cases: **$83,000 lower median annual highlight figure**. The [estimator](/estimator/fintech/) uses a separate $83k model reference. Equal figures in some sectors do not make these the same statistic. The population is the 74 published case studies, with one selected highlight figure per case. It is not a representative sample of all SMBs or a total of every finding in each audit. A lower median is the middle value after sorting, using the lower of the two middle values for an even count. Published annual figures include different outcome types; they are not all collected cash, profit or recurring savings. Case publication dates do not establish common observation, implementation or recovery periods; use each case for its supported timing and outcome. Separate acquisition from risk adjusted contribution, fraud, servicing and retention. Lending, payments and wealth businesses have different economics; the shared model does not capture those differences. ## Where Fintech budgets leak Fintech acquisition is where 4 of the 7 published audits found their money, $324k a year in case figures. The largest finding, $96k a year in 7 days, was sign up bonuses optimized for installs rather than funded accounts. The others in the group follow the same shape: a [CAC](/glossary/cac/) [payback](/glossary/payback-period/) twice what the board believed once onboarding was counted, interchange margin that varied widely by acquisition channel, and channels judged on approved loan CAC while their default rates differed. Incentives and commissions add 2 cases. A referral program paid out on volume that was largely self referred or wash activity, and one broker commission rate applied across products with very different loss ratios. The last case is cost to serve, where human planning support went to accounts whose asset based fee never covered it. An install, an approval or a sign up is not a customer who funds, transacts and repays. Every audit below scores each channel on that risk adjusted contribution, and keeps lending, payments and wealth economics apart. Three patterns across the 7 published Fintech cases. Each card names the cases it rests on; open one for its evidence. The five patterns behind them are defined in [the margin leak guide](/margin-leaks/). Acquisition ### Paying for sign ups, not profitable users Channels judged on installs, approvals or a [CAC](/glossary/cac/) that leaves out onboarding look efficient until they are scored on funded, transacting and repaying users, and on the interchange margin each one brings. 4 of the 7 published cases · $57k to $96k a year - [Incentive spend acquired users who never funded](/cases/incentive-spend-acquired-users-who-never-funded/), −$96k a year - [CAC payback was twice what the board believed](/cases/cac-payback-was-twice-what-the-board-believed/), +$57k a year - [Interchange margin varied wildly by acquisition channel](/cases/interchange-margin-varied-wildly-by-acquisition-channel/), +$83k a year - [Acquisition ignored default rate by channel](/cases/acquisition-ignored-default-rate-by-channel/), +$88k a year Incentives and commissions ### Rewards paid regardless of what they bring Referral rewards paid on self referred or gamed volume, and one commission rate applied across products with very different loss ratios, pay the same for very different value. 2 of the 7 published cases · $72k to $83k a year - [Referral rewards were paid on self referred and gamed volume](/cases/referral-rewards-were-paid-on-self-referred-and-gamed-volume/), −$83k a year - [Broker commissions were flat across very different loss ratios](/cases/broker-commissions-were-flat-across-very-different-loss-rati/), +$72k a year Cost to serve ### Service costs above what small accounts earn Human planning support offered to accounts whose asset based fee never covers it turns the smallest accounts into a loss. 1 of the 7 published cases · $61k a year - [Free planning support cost more than small accounts earned](/cases/free-planning-support-cost-more-than-small-accounts-earned/), +$61k a year The largest published Fintech finding $96,000 a year, found in 7 days Incentive spend acquired users who never funded.
