Calculate the percentage increase from one value to another.
The percentage increase formula is:
Percentage Increase = ((New Value - Original Value) / Original Value) x 100
For example, if a price goes from $100 to $150:
((150 - 100) / 100) x 100 = 50% increase
If the result is negative, the value actually decreased. In that case, consider using the Percentage Decrease Calculator.
