Calculate Percentage Increase Now →The Formula for Percentage Increase
The basic formula to calculate percentage increase is:
Percentage Increase = [(New Value - Original Value) / Original Value] * 100
Let's break down what each part of the formula means:
- New Value: The value you're comparing to the original value.
- Original Value: The starting value.
Step-by-Step Calculation
- Find the Difference: Subtract the original value from the new value to determine the amount of increase.
- Divide by the Original Value: Divide the increase by the original value. This gives you the decimal form of the increase.
- Multiply by 100: Multiply the decimal by 100 to express the increase as a percentage.
Example Scenario
Let's say a product's price increased from $80 to $100. To calculate the percentage increase:
- Difference: $100 - $80 = $20
- Divide: $20 / $80 = 0.25
- Multiply: 0.25 * 100 = 25%
Therefore, the price increased by 25%.
Real-World Applications
Percentage increase is used in various scenarios:
- Finance: Calculate investment returns, revenue growth, or expense increases. For example, understanding annual percentage increase helps determine long-term investment strategies.
- Retail: Track sales growth, price changes, and marketing campaign effectiveness.
- Science: Determine the percentage change in experimental data.
- Personal Life: Monitor weight loss progress, track savings growth, or analyze changes in utility bills.
Why Use a Percentage Calculator?
While the formula is straightforward, calculating percentage increase manually can be time-consuming, especially with complex numbers. A percentage calculator, like the one available on PercentageFinder.org, simplifies this process. You can instantly find what percent of a number is (e.g., what is 15% of 200), figure out what percentage one number is of another (e.g., 30 is what percent of 150), or quickly calculate increase percentage between two numbers (like going from 80 to 100). Just enter your numbers and get immediate results!
Percentage Decrease
It's also useful to understand percentage decrease, which is calculated similarly:
Percentage Decrease = [(Original Value - New Value) / Original Value] * 100
Remember, a negative result from the percentage increase formula indicates a decrease.

Example of adding 20% to a number
To add 20% to a number:
- Divide the original number by 100 to get 1% of it.
- Multiply 1% by your desired percentage, in this case, 20.
- Add the product of the previous step to your original number.
Now you know how to add 20% to your number!
