How Does Compound Interest Work?

A laptop, calculator, and a finance sheet with someone holding a pen

Suppose you invested $1000 with a 5% interest rate that will compound every year.

This will make your gross amount $1102.5.

As this continues, your initial investment (principal) increases exponentially yearly.

Compound Interest Example

Compound interest has exponential increments solely because of this difference.

Now, it’s simply a matter of altering the values to calculate your compound interest.

Note:Don’t forget to place commas between the values.

Compound Interest Formula

But often, we want to calculate quarterly, monthly, or even daily compound interests.

It’s time to understand how to calculate compound interest for an intra-year period.

In our initial example, we put N=1 because compounding happens only once per year.

Compound-Interest

Similarly, for the daily compound interest, we’ll put N=365.

you’re free to use it to calculate the compound interest for an intra-year period.
