Percentage Difference Calculator — FAQs

Increase vs difference?

Percentage change is relative to the old value; percentage difference is relative to the average — use it when neither number is 'before'.

Why isn't +50% followed by −50% neutral?

100 → 150 is +50%, but 150 → 100 is −33% — each step is measured from a different base.
