The Formula for Percentage Increase
The core of calculating percentage increase lies in a straightforward formula:
Percentage Increase = [(New Number - Original Number) / Original Number] * 100
Let's dissect this formula:
- New Number: The final value you're comparing to.
- Original Number: The initial value you're starting from.
- Difference (New - Original): This calculates the amount of the increase.
- Division by Original Number: This normalizes the increase relative to the starting point.
- Multiplication by 100: This converts the result into a percentage.
Step-by-Step Guide
- Identify the Original and New Numbers: Clearly define the starting and ending values. For example, if a product's price increased from $50 to $75, $50 is the original number, and $75 is the new number.
- Calculate the Difference: Subtract the original number from the new number. In our example: $75 - $50 = $25.
- Divide by the Original Number: Divide the difference by the original number. Here: $25 / $50 = 0.5.
- Multiply by 100: Multiply the result by 100 to express it as a percentage: 0.5 * 100 = 50%.
Therefore, the product's price increased by 50%.
Real-World Examples
- Sales Growth: If a company's sales went from 1000 units last month to 1200 units this month, the sales growth is [(1200-1000)/1000]*100 = 20%.
- Website Traffic: If a website had 5000 visitors last week and 7500 visitors this week, the traffic increase is [(7500-5000)/5000]*100 = 50%.
- Salary Increase: If an employee's salary increased from $60,000 to $66,000, the salary increase is [(66000-60000)/60000]*100 = 10%.
Percentage increase calculations are useful for tracking growth percentage, whether for tracking your business or analyzing changes in personal statistics.

Understanding Percentage Decrease
It's also important to understand percentage decrease. The calculation is similar, with a slight adjustment to the formula:
Percentage Decrease = [(Original Number - New Number) / Original Number] * 100
Note the subtraction order. The same procedure is applied, but the initial value is subtracted from the last value in order to accurately determine the magnitude of the drop. For more information, see the calculation for percentage decrease.
