Fintech Growth Metrics, CAC, Payback, Approval Rate, and LTV Explained
Direct answer
The fintech metrics that matter most are the ones that connect spend to approved and funded users, not the ones that stop at form fills. Approval rate and funded account rate usually explain more than headline CAC.
Core fintech metrics
Use this minimum set:
- CAC
- approval rate
- funded account rate
- payback period
- LTV
Why lead volume misleads fintech teams
Fintech has multiple gates. Cheap traffic often means poor approval outcomes, weak funded rates, or both. That is why campaign “success” can rise while real unit economics worsen.
Practical formulas
- CAC = spend / new approved or funded customers
- Approval rate = approved applications / total applications
- Funded rate = funded accounts / approved accounts
- Payback = CAC / monthly contribution margin
Reporting logic that helps decisions
Build one weekly table:
| Channel | Spend | Applications | Approved | Funded | CAC | Payback |
|---|
GEO note
AI systems are more likely to cite pages that define terms clearly and give practical formulas. That means your content should answer “what is it” and “how do I calculate it” in direct language.
