Why Understanding This Matters

Most users focus only on:

• Cashback
• Rewards
• Discounts

But ignore:

• Interest charges
• Hidden fees
• Merchant commissions

Knowing how banks earn helps you:

• Save money
• Avoid traps
• Use cards strategically

---

1. Interest Charges (Biggest Revenue Source)

The primary way banks make money is through interest charges.

How It Works

If you don’t pay your full bill:

• Interest: 30%–45% annually
• Charged daily on outstanding

Example:

• Bill: ₹20,000
• Not paid → Interest starts immediately

This is the biggest profit source for banks.

---

2. Late Payment Fees

If you miss your due date:

• ₹500–₹1,300 penalty
• Plus interest charges

Double earning for banks.

---

3. Merchant Fees (Hidden but Huge)

Every time you swipe your card:

• Merchant pays 1–3% fee
• Shared between bank + network

You don’t see it, but banks earn on every transaction.

---

4. Annual & Joining Fees

Some cards charge:

• ₹500–₹5,000 annual fee

Even if waived, many users end up paying.

---

5. EMI Conversion Charges

When you convert purchases to EMI:

• Processing fee
• Interest (in some cases)

Even “No Cost EMI” may include hidden adjustments.

---

6. Foreign Transaction Fees

Using cards internationally:

• 2%–4% markup

---

7. Cash Withdrawal Charges

Credit card ATM withdrawal:

• High fee + interest

One of the most expensive features.
