They charge a much higher interest on loans than they pay on deposits.
Banks make money by lending out the deposits they receive from customers at a higher interest rate than what they pay out on those deposits. This allows them to earn a profit without needing to have physical money on hand for every dollar they lend out.
Banks are willing to pay interest, because they are turning around and loaning that money out to other people for more interest. They still make money on the deal, and offering interest often attracts customers with larger stacks of money.
Banks make money by loaning out money that has been deposited in the bank and charging interest on it. They are limited as to how much money they can loan by how much money has been deposited in the bank. To encourage people to deposit money in the bank they offer to pay some interest on the deposits. The interest paid on the deposits is less than what they charge people who borrow that money. For example: they might pay 1% annual interest on a deposit of $100,000 - which will cost them $1,000. While that money is on deposit, they loan out $80,000 of it at 5% interest - which makes them $4,000 - for a profit of $3,000. They interest they pay to their customers is an inducement for them to make deposits so that they have more money to loan out and thus can make more money.
The bank does not just hold on to the money you retain in your savings account. Instead, they offer loans to other customers using that money. The loan customers pay an interest to the bank and the bank in turns offers the savings account holders an interest. Since banks make money by lending our money, they offer us an interest.
Banks primarily make money through the interest rate spread between what they pay on deposits and what they charge on loans. When customers deposit money, banks pay them interest, which is typically lower than the interest they charge borrowers. Additionally, banks earn fees for various services, such as account maintenance, transaction processing, and investment management. This combination of interest income and fee-based income constitutes the main revenue stream for banks.
Investment banks provide financial services that are geared toward raising capital such as underwriting, issuance of securities, assisting in Mergers and Acquisitions, and investment management. Unlike commercial banks, they do not take deposits. While investment banks make their money by charging fees for their services, commercial banks earn their money by charging higher interest rates on loans than what they pay for people's deposits.
Most commercial banks make money in three ways. First, the majority of revenue comes from accepting deposits from consumers and then lending that money, with interest, out to individuals and businesses in the form of bank loans. You are most likely very familiar with the fact that banks also make money by charging fees. Additionally, banks even earn returns on investments they make.
Banks make money by lending money to people and charging people for borrowing. The amount banks charge is called interest. Banks borrow money from other people and pay them interest on the amount borrowed. Banks charge more interest on the money they lend than they pay one the money they borrow. That is how they make money. When people deposit money with a bank, the bank is literally borrowing money from some people so they can lend it to other people. That is why banks pay interest.
Pay interest on deposits, use it for their operational expenditure, to pay salaries to its employees etc. Pay interest on savings accounts
By paying out less in interest on deposits than it earns in interest on loans

One of the main functions of banks is to accept deposits. Deposits may be fixed, saving, current etc Banks will have to pay interest to the customers on the basis of the amount deposited by them. Deposits are used for the purpose of lending but since banks are using other peoples money to do business, it should make shure that it will be able to repay the deposits to the respective customers when they claim for it. The management of all this is called deposit management.
