Frequently Asked Questions

What does a 100% decrease mean?

A 100% decrease means the value has dropped entirely to zero. For instance, if you had $50 and spent all of it, the decrease is 100%.

Is percentage decrease the same as a discount?

Yes! In retail, a percentage decrease is identical to a discount. If a $100 item drops to $80, that is a 20% decrease, meaning you received a 20% discount.

Can a percentage decrease be more than 100%?

Generally, no. Since you cannot have less than nothing of a physical quantity, the maximum decrease is 100% (which leaves you with zero). However, in financial contexts involving debt, negative equity can exist.
