Compound interest is interest that is calculated from the principal of the savings and accumulated interest over a certain period. The term compound means there is “interest on interest”. This is why you can get interested that is many times the interest set by the current bank.
Interest accumulated over a certain period and added to the principal amount will result in a greater value. Are you interested in the calculations?
How It Works and Its Functions
Compound interest earned from the principal and interest accumulated over a certain period. Usually, this interest is calculated periodically, namely 12 times a year, 4 times a year, 6 times a year, or annual interest.
This is what makes interest income affect the growth of money. For more details, here is the compound interest calculation by financial organizations or banks:
The Formula
To calculate how much interest you will get, there is a formula that needs to understood, namely:
P x (1 + r) n = A
P = Principal or opening balance
R = Bank interest rate per period
N = number of periods
A = Ending Balance
For example, to calculate compound interest for two years on a $1,000 balance at a 5% annual rate, this would be calculated as:
The annual interest rate of 5% multiplied by 12 months is 0.0042. Furthermore, to calculate the period, then 2 years multiplied by 12 months per year, which is 24.
$1,000 x (1+0.0042) 24 = A
$1,000 x 1.106 = A
$1,659 = A
So the final balance you get is $1,659 which has been added up with compound interest over 2 years.
How Compound Interest Works
