Annual P&L per card (USD)

Lounge cost = usage rate × visits × cost per visit. Network-funded share reduces lounge, insurance and concierge cost. Rewards are not network-funded.

Sensitivity: margin per card by spend segment and lounge usage

Benefits are a usage bet: fixed-cost benefits (lounge, insurance, metal card) dilute margin fastest on low-spend cards with high lounge usage. The segments where margin is thinnest are where customer discovery with high-value accounts should decide the benefits stack.
