A big US card issuer once discovered that for every 1,000 people who clicked its "Apply now" button, roughly 340 finished the application, about 210 got approved, and only around 150 activated the card by making a first purchase. That is a 15% click-to-active rate, and every drop was a place where marketing spend evaporated. Your job in this lesson is to find those leaks and put a dollar figure on each one.
In most industries, the funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.View full definition → is: see ad, click, buy. In banking, a regulated wall sits in the middle. Two terms you need up front:
These two steps are where conversion goes to die, and they are non-negotiable. You cannot "growth-hack" them away. You can only reduce the friction around them.
Think of it as six stages. Each has its own metric.

The activation stage matters more in banking than almost anywhere else. An approved credit card that is never used, or a checking account that is opened and never funded, generates zero revenue and often a loss. Marketers call these "dormant" or "never-active" accounts, and they can quietly be 20% to 40% of approvals depending on channel quality.
Let us trace $50,000 of paid spend for a credit card campaign. Numbers below are illustrative for teaching, not a benchmark.
Now the number that matters most:
CAC (customer acquisition cost) = spend / active customers = 50,000 / 1,348 = ~$37 per activated card.

Two transitions destroyed most of the funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.View full definition → above:
1. Start to complete (55%): almost half abandon mid-form. In banking this is usually KYC friction. Long forms, document upload failures, requests to re-key data the bank already has, and identity-verification steps that fail on the first try. Mobile abandonment is worse.
2. Complete to approval (35%): underwriting rejection. Some of this is unavoidable (the applicant genuinely does not qualify). But a chunk is marketing's fault: you targeted the wrong audience and paid to acquire people the bank will always decline.
This second point is the most expensive mistake in banking marketing.

The marketing decision rule is the LTV to CAC ratio. A common heuristic across subscription and financial businesses is that a healthy ratio sits around 3:1 or higher, and that anything near 1:1 means you are buying customers at a loss.
