How Banks Make Money from Free Credit Cards

You got a credit card with no annual fee, some nice cashback, maybe even lounge access. It feels like you're getting something for nothing. So how do banks make money on cards that don't charge you anything upfront?

Turns out, a "free" credit card can still be very profitable for the bank. Here's how.

1. Merchant Fees on Every Transaction

Every time you tap, swipe, or click "Pay Now," the bank makes money. Here's how:

• When you pay with a credit card, the merchant (store, app, airline, etc.) pays a fee — usually 1.5% to 3% of the purchase amount

• A chunk of that goes to your bank as the card issuer

• Even if you pay off your balance in full every month, your bank still gets this fee

This is the most consistent revenue source for banks – and why they love active card users.

2. Interest on Carried Balances

If you don't pay your full bill by the due date, your remaining balance starts to accrue interest—often around 2.99% to 3.85% per month in the UAE.

That's nearly 40–45% annually.

For banks, this is where the real profits lie. Many cardholders pay the minimum due each month and carry a balance, which turns a free card into a long-term money-maker.

3. Fees for "Extras"

Even if there's no annual fee, banks often earn through:

• Late payment fees (AED 230 or more per month if you miss a due date)

• Cash advance fees (withdraw cash from your credit line? Expect 3–5% fees, plus interest from day one)

• Foreign transaction fees (usually 2–3% on international purchases or travel bookings)

• Over-limit or returned payment fees

These small charges add up — especially across a large customer base.

4. Cross-Selling Other Financial Products

Credit cards are often a foot in the door. Once you're a card customer, banks can market:

• Personal loans

• Auto loans

• Balance transfer offers

• Premium cards or upgrades

• Insurance or investment products

Even if the card itself is free, your relationship with the bank can lead to much more revenue down the line.

5. Breakage from Unused Rewards

Not all cardholders redeem their rewards—whether due to complexity, expiry rules, or forgetfulness. That unclaimed cashback or unredeemed air miles?

That's profit.

Banks design loyalty programs knowing that a certain percentage of users won't fully claim what they've earned.

Final Thoughts

A free credit card might not cost you directly, but it's still a revenue engine for the bank. Whether it's through merchant fees, interest, small charges, or cross-selling, banks have multiple ways to make "free" cards very profitable.

That's not necessarily a bad thing — if you manage your card well, pay on time, and use the perks, you can enjoy real value. Just know the system is designed to earn money either way.
