# Benchmarks that matter: what good looks like
A neobank posts its annual results: 4 million customers, 38% year-over-year growth, and a headline "path to profitability." Buried in the footnotes: monthly churn of 6%, a CACCACCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period. It measures how efficiently you grow.Voir la définition complète → payback period of 22 months, and a loan default rate creeping past 8%. Sounds impressive on stage, terrifying on a spreadsheet. Knowing which number to worry about, and what "good" actually looks like, is the difference between spotting the next Revolut and missing the warning signs of the next Wirecard-style collapse (the German payments firm that imploded in 2020 after an accounting fraud scandal).
This lesson gives you the reference points.
United States: Fintech revenue is estimated around $340 to 400 billion annually as of 2024/2025 (estimate, sources vary by scope, see CB Insights and McKinsey's Global Payments Report
Europe: Smaller in revenue but denser in licensed entities. The UK alone hosts an estimated 3,000+ fintech firms (estimate, Innovate Finance data), helped by the FCA's (Financial Conduct Authority) sandbox model. The EU runs on passporting rules under PSD2 (the second Payment Services Directive) and, since 2024, MiCA (Markets in Crypto-Assets Regulation) for crypto firms.
Growth: Global fintech revenue growth has decelerated from the 2020-2022 boom (20%+ annual) to an estimated 10-15% as of 2025/2026, reflecting higher interest rates, tighter VC funding, and regulatory scrutiny (estimate, BCG/QED "State of Fintech" reports).

1. CAC Payback Period
CAC Payback (months) = CAC / (Monthly Revenue per Customer × Gross Margin %)Example: CACCACCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period. It measures how efficiently you grow.Voir la définition complète → = $150. Monthly revenue per customer = $12. Gross marginGross marginGross margin is the share of revenue left after subtracting the direct cost of producing goods or services, expressed as a percentage of revenue.Voir la définition complète → = 60%.
Payback = 150 / (12 × 0.60) = 150 / 7.2 ≈ 21 months
That's above the 12-month "healthy" line. It means the company needs nearly two years just to earn back what it spent acquiring the customer, before any profit. Investors read this as elevated risk, especially if churn is also high (a customer who leaves in month 15 never becomes profitable).
2. LTV:CAC Ratio
LTV = ARPU × Gross Margin % × Average Customer Lifespan (months)
LTV:CAC = LTV / CACUsing the same customer: ARPU $12, margin 60%, average lifespan estimated at 24 months (implied by ~4% monthly churn).
LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète → = 12 × 0.60 × 24 = $172.80

It measures how efficiently you grow.Voir la définition complète → = 172.80 / 150 ≈ 1.15:1
That's well below the 3:1 healthy benchmark. This business is spending almost as much to acquire a customer as it ever earns from them.
3. Default rate (simple)
NPL rate = Loans 90+ days delinquent / Total loans outstandingIf a BNPL lender holds $500 million in loans and $45 million are 90+ days delinquent: 45/500 = 9%, well into warning territory versus the 3-6% estimated range.

Numbers on a slide deck are marketing. Here's where to verify them.
1. Read the regulatory filings, not the press release. US public fintechs file 10-Ks with the SEC (EDGAR is free and searchable). European neobanks often publish results via national regulators or their own annual reports; look for the actual loan loss provisions, not just "adjusted EBITDAEBITDAEBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) measures a company's operating profitability before financing and accounting decisions, used to compare core performance across firms.Voir la définition complète →."
2. Check the funding source of "growth." Is user growth being bought with unsustainable cashback or referral bonuses? Compare marketing spend growth to revenue growth. If marketing is growing faster, that's a subsidized business, not an efficient one.
3. Separate TPV from revenue. A payments company touting "$50 billion in TPV" tells you almost nothing about profitability if the take rate is thin. Always ask: what's the actual revenue and margin on that volume?
4. Look at cohort behavior, not blended averages. A blended churn ratechurn rateChurn rate is the percentage of customers or revenue lost over a period. It measures how fast a business loses its existing customer base.Voir la définition complète → can hide the fact that new cohorts churn much faster than old ones (or vice versa). Ask for, or model, cohort retention curves when possible.
5. Stress-test the credit book against rate cycles. Lending fintechs that scaled during near-zero interest rates (2020-2021) often saw NPLs spike once rates rose in 2022-2024. Ask how the loan book performed through that cycle, it's the real test.
6. Confirm licensing status. A "bank" without a banking license is typically a BaaS partnership (e.g., Chime partners with The Bancorp Bank and Stride Bank in the US). If the underlying license disappears, so does the product. Always check who actually holds the charter.
