Comments: Compound Interest vs Simple Interest

The interest paid or owed is calculated based on both the principal and interest accrued. Simple interest works in your favor when you borrow money, while compound interest is better for you as an investor.

The start date could be anything as also the maturity date. The periods of each fixed deposit and the interest rate could be different. The interest earned at the end of each quarter will be added to the principal amount and the interest calculated for the next quarter.

However, the total amount can be a little difficult to calculate because your principal balance will decrease as you repay the loan. The interest rate is the amount lenders charge borrowers and is a percentage of the principal. On the positive side, compounding can work to your advantage when it comes to your investments and be a potent factor in wealth creation.
