What is Percent Increase?

Percent increase is a measure of the change in price or value of a product over a specific period. It's calculated as a percentage of the original price. In other words, it represents the amount of increase in price as a percentage of the original price.

Calculating Percent Increase: A Step-by-Step Guide

Step 1: Identify the Original Price and the New Price

In our example, the original price of the Instazoom camera is $75, and the new price is $90.

Step 2: Calculate the Difference Between the New and Original Prices

To find the difference, subtract the original price from the new price:

$90 (new price) - $75 (original price) = $15

Step 3: Divide the Difference by the Original Price

Now, divide the difference by the original price:

$15 ÷ $75 = 0.2

Step 4: Convert the Result to a Percentage

To convert the result to a percentage, multiply by 100:

0.2 × 100 = 20%
