Function of Compound Interest
The core purpose of calculating compound interest is to extract the future value of an investment or a principal amount with the help of interest rate, compounding frequency, and the duration of time over which interest is applied.
If you continuously contribute or add the amount to the compounded amount over time, it not only grows the initial amount further but also increases the accumulated interest.
How does it work?
To calculate the compound interest, you need the following aspects to cover:
- Principal amount: The investment or initial amount of money
- Interest Rate: The rate at which interest is applied.
- Compounding Frequency: It determines how often the interest is applied to the principal amount. It could be quarterly, semiannually, or annually. More frequent compounding leads to rapid growth in money.
- Time: The length of time for which money is invested or saved.
The compounding formula is expressed as follows:
A= P (1 + r/n ) *nt
Where,
A = future value of the invested amount
P = initial investment
r= interest rate
n= the number of times interest is compounded
t= time duration
