About this calculator

Frequently asked questions
How do you calculate percentage change?
Subtract the original value from the new value, divide the difference by the absolute original value, and multiply by 100.
What is the difference between percentage change and percentage difference?
Percentage change compares a new value with an original value. Percentage difference generally compares two values without treating either one as the original or baseline.
Can percentage change be negative?
Yes. A negative change means the new value is lower than the original value. This calculator displays the percentage magnitude and separately identifies the direction as a decrease.
Why can't the original value be zero?
Percentage change requires dividing by the original value. Division by zero is undefined, so a percentage change cannot be calculated from an original value of zero using this formula.
How do I calculate a percentage increase?
Subtract the original value from the new value, divide by the original value, and multiply by 100.
