When we understand it better we can see how when applied to our own money it benefits us in the long term so our money works harder for us.
Use a compound interest calculator to help you see how it can help your money grow.
You will also understand better the interest you pay for the debts you may have and see how banks are making a lot of money using compound interest on your accounts. this particularly applies to credit card debt.
I serve people who want their money to work harder for them instead of it sitting in the bank.
