Starter What is interest?

Interest Interest can be very confusing but it is quite simple when you know about it. If you are borrowing money from a bank you have to pay interest. This is a way for the bank to make their money because you have to pay more for the money you borrowed. Also, as a customer, you can earn extra money on your savings as the bank will pay you a small amount of interest. This interest will depend on the banks’ interest rate for a savings account.

Different types of interest Simple interest This is where the bank pays money to a customer as a percentage of their original balance. For example if you deposited £200 in your saving account and the banks’ interest rate is 10%, you would receive £20 a the end of the year to add to your original deposit. This would leave you with a balance of £220 at the end of the year. This depends on you not withdrawing any money. Interest Rates Interest rates will depend on the bank you chose to go with for your savings account. The higher the interest rate percentage the more money you will receive in interest. So when you are shopping around for the best savings account you must look for the ones with the highest interest rate percentage.

Different types of interest Compound interest Compound interest is the money given to people who have a savings account where the bank pays interest on their original balance and on the interest earned. For example, if you deposited £1,000 into your savings account, after the first year you would receive simple interest of £100 pounds if the interest rate is 10%. This would give you a starting balance of £1,100 at the start of year 2. At the end of year 2 compound interest would be given. You would still get your simple interest rate of £100 but you will also get compound interest of £10. This would give you a grand total at the end of year 2 of £1,210. The compound interest is £10 because you are getting interest on the simple interest from the previous year. This is £100 so 10% of £100 is £10.
