Framework.
Operating CAC is the marketing dollar spent to bring in a new cardholder this quarter. Total marketing expense, allocated by product, divided by gross new accounts. ASC 606 keeps sign-up bonuses and rewards out of the marketing line.
Lifetime Value is the present value of profit that cardholder produces over the years they stay. Annual revenue per active, times margin, times an NPV factor that accounts for tenure and the time value of money.
LTV/CAC ratio is the scoring metric. Above 5x is Excellent. 3x to 5x is Healthy. 1.5x to 3x is Marginal. Below 1.5x is the Acquisition Trap on isolated card economics.
CAC Pyramid.
Three layers, each more conservative than the last.
Operating CAC
Noninterest marketing expense allocated to each product, divided by gross new accounts. The cleanest comparable number across the set. This is the layer shown on the Acquisition Compass charts.
Channel-Loaded CAC
Operating CAC plus the channel cost the marketing line skips. Branch personnel allocation at $250 per consumer checking open, $400 per SMB checking open. CDD/KYC compliance at $100 per retail account. Card opens carry zero branch loading because cards run digital-first across both ecosystems.
Incentive Yield Offsets
Sign-up bonus dollars and reward expense that ASC 606 routes through contra-revenue rather than marketing. Reported separately so Operating CAC stays focused on the marketing dollar.
Lifetime Value.
Annual revenue per active cardholder. Interchange, interest income, late fees, annual fee. Drawn from quarterly disclosures and product-mix assumptions calibrated to each issuer.
Margin. What stays after rewards expense, servicing cost, and credit losses. 45 percent on no-fee. 55 percent on fee-based.
NPV factor. Tenure adjusted for the time value of money. Tenure is 6 years for no-fee TradFi, 9 years for fee-based TradFi, 5 years for fintech. Discount rate is 10 percent. The math comes out to roughly 3.15 on a 6-year horizon and roughly 4.18 on a 9-year horizon.
Every input, every tier, every source.
Each assumption carries a confidence tier. Tier A is disclosed directly by the issuer. Tier B is derived from disclosed components with industry benchmarks. Tier C is estimated from peer data and Curinos, Novantas, and Comperemedia tracking.
Portfolio attrition (gross opens denominator)
| Assumption | Value | Tier | Source |
|---|---|---|---|
| Consumer checking quarterly attrition (TradFi) | 2.5% | B | 10% annual, Curinos and Novantas industry benchmark. |
| Fintech checking quarterly attrition | 4.0% | C | 16% annual reflecting lower primacy lock-in on digital-first checking. |
| SMB checking quarterly attrition | 2.0% | C | 8% annual. SMB attrition lower due to payroll and merchant services bundling. |
Card marketing intensity
| Assumption | Value | Tier | Source |
|---|---|---|---|
| Fee-card marketing intensity multiplier | 1.8x | C | Premium creative, sponsorship leverage, larger sign-up bonuses. Applied versus no-fee baseline. |

| Fee-based share of new card accounts (default) | 25% | C | Premium Rewards, Sapphire, Platinum. Higher fee, lower volume. Tunable per issuer. |
| SMB share of new card accounts (default) | 7% | C | Sub-allocated where banks bundle SMB cards inside total card disclosures. |
Channel-loaded add-ons
| Assumption | Value | Tier | Source |
|---|---|---|---|
| CDD/KYC compliance cost per retail account | $100 | C | Midpoint of the $65 to $140 retail banking range per published industry research. |
| Branch personnel per consumer checking open (TradFi) | $250 | C | Branch-originated checking carries personnel and occupancy cost. |
| Branch personnel per consumer checking open (Fintech) | $0 | B | Digital-first fintechs carry zero branch overhead. |
| Branch allocation per SMB checking open (TradFi) | $400 | C | SMB onboarding requires relationship banker time and KYC documentation. |
| Branch allocation per card open | $0 | B | Cards run digital-first across both ecosystems. |
Incentive yield offsets (ASC 606 contra-revenue)
| Assumption | Value | Tier | Source |
|---|---|---|---|
| Bonus qualification rate | 60% | C | Midpoint of 50 to 70 percent industry range for spend-and-earn sign-up offers. |

Q1 2026 Refinements.
Three issuers carry a refinement to the steady-state assumption stack. Each is published openly.
Wells Fargo card share at 45%
Wells's reported total marketing of $550M in Q1 2026 sits below peer issuers. The asset cap lifted in mid-2025 and the franchise is in active relaunch on Active Cash, Autograph, and Autograph Journey. The steady-state default of 35% card share of consumer-plus-SMB marketing under-allocates the relaunch year. Card share is set to 45% for Wells in Q1 2026, producing $128 no-fee CAC and $231 fee-based CAC.
Amex consumer checking and SMB deposit set to n/a
Amex Personal Savings is online-only and immaterial relative to the card franchise. Consumer checking and SMB deposit report as n/a for Amex.
Capital One Discover integration
Q1 2026 marketing of $1,497M reflects the first full quarter post-Discover integration, up 25% year over year. CAC reads 2.5x on no-fee and 8.1x on fee-based at acquisition velocities of 2.7MM and 1.45MM opens respectively.
Limitations.
- Cross-sell allocation. Branch-anchored issuers convert deposit customers to cardholders inside the relationship. Those opens divide the marketing line even though the marketing did not acquire them. Future refinement.
- Cobrand partner economics. Chase has a large cobrand book (United, Marriott, Southwest, Disney). Cobrand marketing is partly funded by the partner. The framework reads the marketing-line dollars only, which slightly inflates Chase CAC versus a fully-loaded view.
- Fintech membership translation. SoFi, PayPal, and Chime report at the member or active account level. The framework translates to product CAC through product mix per member. The translation is judgment-calibrated.
- Block has zero credit card. Cash App Card and Square Card are debit. The premium and no-fee credit card columns read n/a for Block.
