Okay kiddo, a retail bank is like a store where you can put your money in a safe place. It's like a piggy bank, but much bigger. Instead of just keeping your change in it, you can put your allowance, birthday money, or any other money you might have.
But that's not all, retail banks can also help you with other things you might need with your money. Like, they can give you a card that you can use to buy things you want or need. They can even give you a loan if you need to borrow some money, like if you want to buy a car or go to college.
The people who work at the retail bank are called bankers. They will help you open an account and show you how to use it. They will also help you understand how to save and budget your money so that you can buy the things you want and need.
In exchange for using their services, the bank might charge you a fee or take a small percentage of the money you have in your account. Just like how you might have to give your piggy bank a few coins if you want to buy something you really want.
So, a retail bank is like a safe place to keep your money and can also help you with other things you might need like buying things or getting a loan. The people who work there are called bankers and they will help you understand how to use your account and manage your money.
