How Banks Make Money from Credit Cards in India

Banks earn from credit cards via four streams.

Interchange fee: paid by the merchant on every transaction.

Finance charge: interest on carried balances. The rate is 3.5% to 4.25% per month.

Annual fee: yearly fee on the card.

Late fee plus other fees: late fees, cash advance fees, and EMI fees.

The interchange fee is the most lucrative stream. The finance charge is the most penalising for the cardholder.

The interchange fee

A percentage of every transaction that the merchant pays to the cardholder’s bank.

The cardholder does not pay it directly. The merchant does.

The RBI sets the interchange rate by merchant category.

Government transactions: 0%. Utilities (electricity, water, gas): 0% to 0.4%. Education: 0% to 0.4%. Healthcare: 1%. Telecom: 1% to 1.5%. Fuel: 1%. Retail and online: 1% to 1.5%. Hotels and travel: 2%. Restaurants: 2%. Premium merchants: 2% or more.

The merchant’s acquiring bank takes a small share. This is typically 0.2% to 0.4%.

The rest goes to the issuing bank and the network.

For a 1.5% interchange on a retail transaction: the acquiring bank gets 0.3%.

The network (Visa, Mastercard, and so on) gets 0.5%. The issuing bank gets 0.7%.

The issuing bank earns the largest share. This is why banks are willing to give rewards of 1% to 5%.

The interchange covers part of the rewards cost.

For a ₹1 lakh annual spend on a rewards-earning card: interchange revenue at 1.5% on retail is ₹1,500.

Cost of rewards at 3% via points is ₹3,000. Net cost to bank: ₹1,500. The bank makes a loss on rewards.

So banks lose money on rewards-earning cards at low spend. The bank makes money via annual fee, finance charge, late fees, and cross-sell.

The finance charge

The rate is 3.5% to 4.25% per month. That is 42% to 51% per annum. Plus 18% GST on the finance charge.

For a ₹50,000 carried balance for 12 months: finance charge is ₹21,000 to ₹25,000 before GST.

GST on finance charge is ₹3,780 to ₹4,500. Total revenue to bank is ₹24,780 to ₹29,500.

That is a 50% or higher annual yield on the carried balance.

No other consumer loan product is this profitable.

Most credit-card profit comes from a small fraction of cardholders who revolve balances.

The revolvers are typically 10% to 20% of cardholders. They generate 60% to 80% of credit-card profit.

The bank wants you to revolve just enough to be profitable. But not enough to default.

The sweet spot is 5% to 30% of your credit limit as carried balance.

The annual fee

The rate ranges from ₹0 (lifetime free) to ₹12,500 (super-premium).

Lifetime-free cards give ₹0 revenue from annual fee. The bank earns only interchange and cross-sell.

₹500 to ₹2,500 cards give modest revenue. The fee is mostly waivable via spend.

₹5,000 or more cards give meaningful revenue. The fee is harder to waive.

The annual fee is most banks’ second-largest credit-card revenue stream.

Late fees and other fees

The range for late fees is ₹500 to ₹1,200 per occurrence. This is capped under RBI rules.

The rate for cash advance fees is 2.5% to 3.5% of the cash amount. The minimum is ₹250 to ₹500.

The rate for EMI fees is 1% to 2% of the EMI principal.

These fees are high-margin. The bank spends little to provide them.

A single missed payment can earn the bank ₹1,000 in late fees.

A single cash advance can earn ₹1,750 or more.

The cross-sell revenue

Banks are willing to lose money on rewards because credit-card customers are valuable.

They have a credit history, regular income, and digital banking activity.

Cross-sell is profitable. 60% or more of credit-card customers take a personal loan, mortgage, or fixed deposit within 5 years.

A credit-card customer is worth ₹50,000 to ₹2,00,000 in lifetime profit to the bank.

The rewards are a customer acquisition cost.

Personal loans: 14% to 22% per annum. Home loans: 8.5% to 9.5% per annum, large principal. Car loans: 8.5% to 11% per annum. Fixed deposits: 6.5% to 7.5% per annum.

Mutual funds and insurance: commissions on sale.

The credit card opens the door. The cross-sell is the real revenue.

What this means for you as a cardholder

If you pay in full every cycle: you cost the bank about ₹1,500 per year in interchange after rewards cost.

The bank earns ₹0 from you in fees. It relies on cross-sell.

The bank may waive annual fees to retain you as a future cross-sell prospect.

You are a good customer from the bank’s perspective. You have low risk and high cross-sell potential.

If you carry a balance: you cost the bank nothing in interchange. The bank earns ₹1,500.

The bank earns ₹21,000 to ₹25,000 per year in finance charge on a ₹50,000 balance.

The bank earns ₹1,000 or more per missed payment.

You are a profitable customer from the bank’s perspective.

The bank will reward you with fee waivers to keep you revolving.

If you take cash advances: you cost the bank nothing.

The bank earns 2.5% to 3.5% cash advance fee. Plus 2.5% to 3.5% per month interest.

You are a very profitable customer from the bank’s perspective.

Most banks segment credit-card customers as transactors, revolvers, and defaulters.

Transactors (pay in full): 70% to 80% of customers. They generate 20% to 30% of revenue.

Revolvers (carry balance): 15% to 25% of customers. They generate 50% to 70% of revenue.

Defaulters (90 or more days past due): 2% to 5% of customers. They generate 0% of revenue. They are a write-off.

The 15% to 25% of revolvers generate most of the bank’s profit. The transactors are kept as future cross-sell prospects.

What the bank wants from you

The bank wants you to use the card frequently. This gives high interchange revenue.

The bank wants you to revolve a small balance. This gives finance charge revenue.

The bank wants you to miss occasional payments. This gives late fee revenue.

The bank wants you to take cash advances occasionally. This gives cash advance fee revenue.

The bank wants you to stay with the bank. This gives cross-sell revenue.

What you should do as a cardholder

Use the card frequently. This maximises rewards.

Pay in full every cycle. This avoids finance charge.

Never miss payments. This avoids late fee.

Never take cash advances. This avoids cash advance fee.

Cross-shop for credit cards every 3 to 5 years. This keeps banks competing.

This is the disciplined cardholder who earns maximum rewards and pays minimum fees.

The bottom line

Banks make money from credit cards via interchange, finance charge, annual fee, late fee, and cross-sell.

The most profitable revenue stream per cardholder is the finance charge on carried balances.

The cardholder’s optimal strategy: pay in full every cycle, use the card for routine spend, avoid cash advances, and redeem rewards strategically.

The bank’s strategy: maximise cardholders who revolve balances.

The bank’s revenue model favours revolvers. The disciplined cardholder earns the rewards and pays none of the interest.

The disciplined cardholder earns 3% to 5% on spend. The bank loses ₹1,500 to ₹3,000 per year on the disciplined cardholder.

The bank offsets this via cross-sell. The win-win is disciplined cardholder plus cross-sell prospect.
