Use this percentage increase calculator to calculate the percent growth between a starting value and a final value. This tool helps you quickly measure change in prices, costs, revenue, or other values by applying the standard percentage increase formula.
Calculating percentage increase is useful when you want to measure how much a value has grown over time. For example, you may want to know how much a product price increased, how much revenue grew year-over-year, or how much a cost has changed. A percentage increase calculator simplifies the process by automatically applying the formula once you enter the original value and the new value.

What Is Percentage Increase?
Percentage increase measures how much a value has grown compared to its original value. It expresses the increase as a percentage rather than a raw number, which makes it easier to compare changes across different values or time periods.
Businesses frequently use percentage increase calculations to track revenue growth, monitor cost changes, or measure price adjustments.
Percentage Increase Formula
The percentage increase formula compares the difference between two values relative to the original value.
Percentage Increase =
(Final Value − Original Value) ÷ Original Value × 100
The calculation works in three steps:
- Subtract the starting value from the final value
- Divide the difference by the original value
- Multiply the result by 100 to convert it into a percentage
Example Calculation
Suppose a product cost increases from $100 to $130.
Step 1:
130 − 100 = 30
Step 2:
30 ÷ 100 = 0.30
Step 3:
0.30 × 100 = 30% increase
So the price increased by 30 percent.
Why Percentage Increase Matters
Calculating percentage increase helps you understand how values change over time. It is commonly used in:
- business growth analysis
- financial reporting
- investment performance
- salary increases
- cost and price tracking
Because the calculation uses relative change instead of absolute numbers, it allows better comparisons across different scales.
Cost Increase Example
A cost increase is one of the most common uses of percentage calculations. If a manufacturing cost rises from $250 to $300, you can use the percentage increase formula to measure the change.
Increase = 300 − 250 = 50
Percentage increase = (50 ÷ 250) × 100
Percentage increase = 20%
This tells you the cost increased by 20 percent.
Frequently Asked Questions
How do you calculate percentage increase?
Subtract the starting value from the final value, divide the result by the starting value, and multiply by 100.
What is the formula for percentage increase?
Percentage Increase =
(Final Value − Starting Value) ÷ Starting Value × 100.
Can percentage increase be negative?
If the final value is lower than the starting value, the result becomes negative. This indicates a percentage decrease instead of an increase.
