About This Tool
The Percentage Increase Calculator finds the percentage increase between an original value and a new, higher value — useful for tracking growth, raises, price changes and more.
Frequently Asked Questions
How is percentage increase calculated?
Percentage Increase = ((New Value - Original Value) / Original Value) × 100.
What if the result is negative?
A negative result means the new value is actually lower than the original — that is a percentage decrease, not an increase.
Can I find the new value from a percentage increase?
Yes — if you enter the original value, the tool shows the new value when you apply that percentage increase.
