A bank is a place where people keep their money safe. People put money into the bank. This is called a deposit. They can also take money out. That is called a withdrawal.

Banks help people save money. Some people open savings accounts. The bank keeps the money and even gives a little extra. This extra is called interest. It helps your money grow slowly.

Banks also help people buy big things. If someone wants to buy a house or car, the bank can lend them money. People pay it back little by little. This is called a loan.

Many people use bank cards. These cards help them buy things or get money from a machine called an ATM. Some people also use apps to check their money on phones.

Banks are very important. They help us keep money safe, save for the future, and buy things we need.
