Where:

**IR**is the interest revenue.**PA**is the principal amount.**IR**is the interest rate (expressed as a percentage).

### How to Use

To effectively use the Interest Revenue Calculator, follow these steps:

**Determine the Principal Amount (PA):**Identify the total amount of money that you want to invest or the amount already invested.**Identify the Interest Rate (IR):**Determine the annual interest rate as a percentage. This rate is often provided by banks or financial institutions.**Input Values into the Formula:**Substitute the values for the principal amount and interest rate into the formula IR = (PA * IR) / 100.**Calculate Interest Revenue (IR):**Perform the calculation to find the interest revenue generated over the specified period.**Interpret the Results:**Use the calculated interest revenue to understand how much income your investment will generate.

### Example

Let’s say you want to calculate the interest revenue for a principal amount of $1,000 at an interest rate of 5%.

Using the formula:

**IR = (PA * IR) / 100**

**IR = (1000 * 5) / 100**

**IR = 5000 / 100**

**IR = $50**

In this example, the interest revenue generated would be $50.
