Interest Increase Calculator

The Interest Increase Calculator helps to compute the interest accrued on a principal amount over a given time at a specified interest rate. It also provides the total amount after applying the interest.

Formula

The formula used to calculate the interest increase is as follows:

\[ \text{Interest Increase} = \text{Principal} \times \frac{\text{Rate}}{100} \times \text{Time} \]

\[ \text{Total Amount} = \text{Principal} + \text{Interest Increase} \]

Example Calculation

For a principal of $1000, a rate of 5%, and a time period of 3 years:

\[ \text{Interest Increase} = 1000 \times \frac{5}{100} \times 3 = 150 \text{ dollars} \]

\[ \text{Total Amount} = 1000 + 150 = 1150 \text{ dollars} \]

Importance

Understanding how interest increases over time can help individuals and businesses make better financial decisions, especially when taking loans or investing money.
