**Calculation History:**

In the world of mathematics and finance, percentages play a crucial role in quantifying change. One valuable tool that simplifies the process of calculating percentage increases is the “Percentage Increase Calculator.” This tool is used to determine the percentage change between two values and is widely employed in various fields such as economics, business, and statistics.

## Concept of Percentage Increase

Percentage increase refers to the change in a value relative to its original value, expressed as a percentage. It is commonly used to analyze growth, inflation, price changes, and more. The concept is straightforward: to calculate the percentage increase, we need the original value (old value) and the new value.

## Formulae for Percentage Increase

To calculate the percentage increase, we can use the following formula:

**Percentage Increase = ((New Value – Old Value) / Old Value) * 100**

Where:

**New Value**: The updated or final value.**Old Value**: The initial or original value.

Let’s illustrate this formula with an example.

## Example Calculations

### Example 1: Calculating Percentage Increase in Stock Price

Suppose you have invested in a stock with an initial price of $50, and the current price is $65. To find the percentage increase in the stock price:

**Percentage Increase = (($65 – $50) / $50) * 100 = 30%**

This means that the stock price has increased by 30% since your initial investment.

### Example 2: Calculating Percentage Increase in Population

Consider a town with a population of 5,000 people a decade ago, and now the population stands at 7,500. To calculate the percentage increase in population:

**Percentage Increase = ((7,500 – 5,000) / 5,000) * 100 = 50%**

The town’s population has increased by 50% over the past decade.

## Real-World Use Cases

The Percentage Increase Calculator finds application in various real-world scenarios:

### Finance and Investments

Investors and financial analysts use it to track changes in stock prices, bond yields, and portfolio values. It aids in making informed decisions and assessing the performance of investments.
