How do Visa & Mastercard actually make money?
A $100 card payment flows like this:
- Merchant pays a “discount fee” to accept cards
- Acquirer keeps a small cut ($0.25)
- Issuer takes the big share ($1.75 interchange)
- Networks charge assessments and per-swipe fees
Key insight:
Visa & Mastercard don’t lend money.
They monetize the rails:
- Set interchange frameworks
- Charge network and usage fees
- Scale across billions of transactions
Meanwhile issuers take the risk:
Front the money, manage fraud, handle credit
Payments look simple.
The economics aren’t.
