Frequently asked questions
How do I calculate percentage increase?
Subtract the original value from the new value to get the increase amount, divide by the original value, then multiply by 100.
What if the new value is lower, not higher?
The calculator will still compute a result, but it will be negative, meaning the value actually decreased — use the Percentage Decrease Calculator for that framing.
How is percentage increase used in salary hikes?
It's the same math used for a salary hike: (New salary − Old salary) / Old salary × 100. See the Salary Increment Calculator for a salary-specific version.
