- Simple Interest
- Compound Interest

Simple interest is the interest paid only on the principal amount. It is calculated by multiplying the principal amount, the interest rate, and the time period for which the interest is being calculated.

Compound interest is the interest paid on both the principal amount and the accumulated interest. This means that the interest earned in each period is added to the principal, and the subsequent interest is calculated using the new principal. Compound interest can be calculated on a daily, weekly, monthly, quarterly, or annual basis.

## Calculating Simple Interest

To calculate simple interest, you need to know the principal amount, the interest rate, and the time period. The formula for simple interest is:

Formula | Example |
---|---|

Simple Interest = (Principal * Rate * Time) / 100 | If you borrow $1,000 at an interest rate of 5% for 2 years, the simple interest would be: Simple Interest = ($1,000 * 5 * 2) / 100 = $100 |

## Calculating Compound Interest

To calculate compound interest, you need to know the principal amount, the interest rate, the compounding frequency, and the time period. The formula for compound interest is:

Formula | Example |
---|---|

Compound Interest = Principal * ((1 + Rate / Frequency)^(Frequency * Time) – 1) | If you invest $1,000 at an interest rate of 5% compounded annually for 2 years, the compound interest would be: Compound Interest = $1,000 * ((1 + 0.05 / 1)^(1 * 2) – 1) = $105.13 |
