How Banks Make Money: Beyond Loan Interest

Kokila Chokkanathan
While most people associate banks with earning from interest on loans, modern banks have multiple revenue streams. Here’s a detailed breakdown:

1. Interest on Loans (Primary Revenue Source)

  • Banks lend money to individuals, businesses, and governments.
  • The interest charged on loans is usually higher than the interest banks pay to depositors.
  • This net interest margin is the largest source of profit.
2. Fees and Charges

Banks earn substantial income from service fees, including:

  • Account Maintenance Fees: Monthly or annual charges for savings/current accounts.
  • ATM & Transaction Fees: Charges for withdrawals beyond free limits or using other bank ATMs.
  • Overdraft & Penalty Fees: Fees when account limits are exceeded or loan installments are late.
  • Credit Card Fees: Annual fees, late payment fees, and foreign transaction fees.
3. Investment Income

  • Banks invest in government bonds, corporate bonds, and securities.
  • Dividends and capital gains from these investments contribute to income.
  • Banks also earn from trading financial instruments like stocks, currencies, or derivatives.
4. Wealth Management and Advisory Services

  • Many banks offer portfolio management, mutual funds, insurance, and retirement planning.
  • They earn through management fees, advisory fees, and commissions.
5. Foreign Exchange Services

  • Banks facilitate currency exchange, remittances, and international transfers.
  • They charge conversion fees and service charges, which generate revenue.
6. Safe Deposit Locker Services
