What is Percentage Increase?

Percentage increase measures the relative change between an initial value and a new value. It is expressed as a percentage of the initial value. A positive percentage indicates an increase, while a negative percentage indicates a decrease.

Knowing how to calculate percentage increases allows you to:

  • Track sales growth or decline
  • Compare investment performance
  • Analyze changes in website traffic
  • Understand inflation rates
  • Monitor progress toward goals

Formula for Percentage Increase

The formula for calculating percentage increase is as follows:

Percentage Increase = [(New Value - Initial Value) / Initial Value] * 100

Where:

  • New Value is the value you are comparing to
  • Initial Value is the starting value

Steps to Check Percentage Increase

  1. Identify the Initial and New Values: Determine the two numbers you want to compare. The initial value is your starting point, and the new value is the value you want to compare it to.
  2. Calculate the Difference: Subtract the initial value from the new value. This gives you the amount of increase or decrease.
  3. Divide by the Initial Value: Divide the difference by the initial value. This step normalizes the change relative to the starting point.
  4. Multiply by 100: Multiply the result by 100 to express the change as a percentage.
  5. Interpret the Result: A positive percentage indicates an increase, while a negative percentage indicates a decrease.

Examples of Calculating Percentage Increase

Example 1: Sales Growth

A business increased its sales from $10,000 in January to $12,000 in February. What is the percentage increase in sales?

Using the formula:

Percentage Increase = [($12,000 - $10,000) / $10,000] * 100 = [($2,000 / $10,000)] * 100 = 0.2 * 100 = 20%

The sales increased by 20%.

Example 2: Website Traffic

A website's traffic increased from 500 visitors per day to 750 visitors per day. What is the percentage increase in traffic?

Using the formula:

Percentage Increase = [(750 - 500) / 500] * 100 = [250 / 500] * 100 = 0.5 * 100 = 50%

The website traffic increased by 50%.

Example 3: Investment Return

An investment increased in value from $500 to $600. What is the percentage increase in the investment's value?

Using the formula:

Percentage Increase = [($600 - $500) / $500] * 100 = [$100 / $500] * 100 = 0.2 * 100 = 20%

The investment increased in value by 20%.
