Find the percentage increase or decrease from one number to another — for prices, statistics, weights, or any before-and-after comparison.
How it works
- Enter the baseline original value.
- Enter the new updated value.
- Read whether it is a percentage increase or decrease, and by exactly how much.
Frequently asked questions
How is this different from percentage difference?
Percentage change has a clear direction (from old to new). Percentage difference compares two values symmetrically without a baseline.
Why divide by the original?
The change is measured relative to the starting point, which is the original value.
Can it handle a decrease to zero?
A drop to zero is a 100% decrease. Change from zero, however, is undefined (you cannot divide by zero).
