What are simple interests and Compound interests?

What are simple interests and compound interests is a common question. When learning about interests and loans, what is simple interest and compound interest is asked quite often. The article has provided relevant answers to this question.

The simple interest formula is: O * i * n, here, O stands for the original amount, n stands for years of the loan and i stands for the interest rate. For example, person A borrows ₹1800. The interest that is charged is fixed and paid annually. The time allotted is 2 years. The interest rate is 2%. So, the simple interest will be calculated as O * i * n

1800 * 0.02 * 2 = 21600
