Co-branded Card Economics Simulator — Bank vs Brand P&L
Plug in any co-brand partnership scenario. See exactly where the money goes, who breaks even, and why so many of these decks look great until year two.
Most co-branded credit card press releases land the same way: glossy logos, big launch event, promises of "deep alignment." Eighteen months later the program is on a quiet diet — reduced rewards, scaled-back marketing, the two teams blaming each other.
The reason is almost always the unit economics. A co-brand card has a real P&L for both the bank and the brand. If activation rates miss, if revolver rates are lower than modeled, if the reward-funding split is wrong, the partnership stops working — well before either side admits it publicly.
Use the simulator below to stress-test any scenario you care about. Slide the inputs, watch each side's P&L move in real time, hit a preset to load realistic numbers for an e-commerce, premium-travel or quick-commerce card. The math is laid out fully — adjust your priors, run a different scenario, share with your team. Pairs naturally with the long-form essay Why most co-branded cards fail in year two.
