The annual fee tripped me up for a second because everything else is monthly.
Start by clarifying all given figures and their time units (monthly vs annual), then compute monthly profit per cardholder by summing revenue streams and subtracting costs, and finally scale to the full portfolio and annualize. Structure your answer logically, stating assumptions and showing calculations clearly.
Pro tip: Always state your assumptions explicitly (e.g., that revenue and cost figures are per cardholder per month) and consider edge cases like seasonality or changing customer behavior, which shows business acumen beyond raw math.
Confirm that the given revenue and cost figures are monthly and per cardholder, and identify all components: swipe revenue, annual fee, interest revenue, and fraud-prevention cost.
Sum the monthly revenue streams (swipe revenue + annual fee/12 + interest revenue) and subtract the monthly fraud-prevention cost to get monthly profit per cardholder.
Multiply the monthly profit per cardholder by the total number of active cardholders (500,000) to get total monthly profit, then multiply by 12 to obtain annual profit.
Verify the result by checking order of magnitude and discussing potential real-world factors (e.g., attrition, seasonality) that could affect the calculation.

Divide $25M by the $223 per-card margin and you get roughly 112,000 incremental cardholders needed.
Start by clarifying the revenue model: Capital One earns from interchange fees, interest, and annual fees on new cardholders. Estimate the annual net revenue per cardholder, then divide the $25M campaign cost by that figure to find the break-even number of cardholders, adjusting for retention and activation rates.
Pro tip: Show that you understand the difference between gross and net new cardholders—account for cannibalization and attrition. Also, mention that break-even should consider the lifetime value (LTV) of a cardholder, not just first-year revenue.
Identify how Capital One monetizes a cardholder: interchange fees (percentage of spend), interest on balances, annual fees, and other fees. Assume a typical cardholder profile if not given.
Calculate expected annual revenue per cardholder by multiplying average spend by interchange rate, adding interest income based on average balance and APR, and subtracting servicing costs. Use industry benchmarks if needed.
Account for the fact that not all acquired cardholders are net new—some may have switched from other Capital One cards. Also, consider activation and retention rates to determine the effective number of cardholders contributing revenue.
Divide the $25M annual campaign cost by the annual net revenue per cardholder to get the break-even number of net new cardholders needed in the first year.
If the campaign is expected to generate cardholders who stay for multiple years, calculate break-even using lifetime value instead of annual revenue, which lowers the required number of cardholders.

Start by restating the break-even calculation and the key assumptions behind it, then give a clear recommendation with a confidence level. Walk through the business implications, risks, and potential upside, and conclude by tying the decision to Capital One's strategic priorities and suggesting next steps or validation.
Pro tip: Acknowledge that break-even is a static snapshot and that real-world decisions require sensitivity analysis and consideration of strategic options like scaling or renegotiating terms. Show you can think beyond the model to the business context.
Briefly recap the break-even point, the key inputs (e.g., fixed costs, variable costs, revenue per ride), and the assumptions made. This sets the foundation for your recommendation.
Give a clear yes/no/maybe recommendation based on the break-even result, and indicate your level of confidence. For example, 'Yes, if we can achieve X volume, but with moderate confidence due to Y risk.'
Explain how you arrived at the recommendation: compare break-even volume to expected demand, discuss the margin of safety, and highlight any critical assumptions that could change the outcome.
Identify key risks (e.g., lower-than-expected demand, higher costs) and perform a quick sensitivity analysis to show how the break-even and profitability change under different scenarios.
Connect the decision to Capital One's broader goals (e.g., customer acquisition, market expansion) and propose next steps such as a pilot, further data collection, or renegotiation of terms.
