Percentage Rate Calculator

Formula

The formula to calculate the Percentage Rate is:

\[ \text{PR} = \left( \frac{\text{V2} - \text{V1}}{\text{V1}} \right) \times 100 \]

Where:

\(\text{PR}\) is the Percentage Rate (%)
\(\text{V2}\) is the final value
\(\text{V1}\) is the initial value

What is Percentage Rate?

Percentage Rate is a measure of the change in value expressed as a percentage. It is calculated by dividing the change in value by the initial value and then multiplying by 100. This metric helps in understanding the relative change in value over time.

Example Calculations

Example 1:

Initial Value (V1): 50
Final Value (V2): 75

Using the formula:

\[ \text{PR} = \left( \frac{75 - 50}{50} \right) \times 100 = 50 \% \]

Example 2:

Initial Value (V1): 100
Final Value (V2): 120

Using the formula:

\[ \text{PR} = \left( \frac{120 - 100}{100} \right) \times 100 = 20 \% \]
