Credit Card Portfolio Annual Profit

You manage a portfolio of 500,000 active credit-card accounts. Each active card generates multiple revenue streams and incurs a cost.

Given:

  • Annual fee: $79 per year
  • Other revenue: $2 per year
  • Interest revenue: $15 per month
  • Fraud-prevention cost: $5 per month

Calculate the portfolio's total annual profit. Show your steps and assumptions.

Constraints & Assumptions

  • Monthly figures must be annualized before summing.
  • Treat all 500,000 accounts as active for the full year.
  • Ignore taxes, charge-offs, rewards, servicing, funding costs, and acquisition costs unless stated.
  • Report both per-card annual profit and total portfolio profit.

Clarifying Questions to Ask

  • Are all accounts active for the full 12 months?
  • Are fraud-prevention costs the only costs included?
  • Should expected losses, rewards, servicing, and funding costs be excluded?
  • Are the revenue figures averages per active card?

What a Strong Answer Covers

  • Annualizes monthly interest revenue and monthly fraud-prevention cost.
  • Adds annual fee, other revenue, and annualized interest to get annual revenue per card.
  • Subtracts annualized cost to get per-card profit.
  • Multiplies per-card profit by 500,000 active accounts.
  • Presents the final answer clearly in dollars and notes excluded cost categories.

Follow-up Questions

  • How would the answer change if only 90% of cards are active all year?
  • What costs would you add for a full profitability model?
  • How would expected credit losses affect the calculation?
