The new amount of money in the account will be £110 or 110% of the original. Compound interest means that every time interest is paid on an amount the added interest will also receive interest thereafter. Compound interest therefore accounts for a difference of £9.27 in the example shown.

Daily compound interest is calculated using a version of the compound interest formula. To begin your calculation, take your daily interest rate and add 1 to it. Then, raise that figure to the power of the number of days you want to compound for.

Therefore, we can combine all monthly payments into one sum, which would result in £1,200. If you want to see your savings grow then compound interest can be your best friend.

In the third year, interest is accrued on the initial deposit and all the interest previously received.
