Frequently asked questions
Why isn't a 50% rise undone by a 50% fall?
The fall applies to a bigger base. 100 → 150 → 75, so you need a 33.3% fall to return to 100.
Can percentage change exceed 100%?
Yes for increases — tripling is +200%. Decreases cannot exceed −100% because a value cannot fall below zero from a positive base.
