What is a percentage point?

The plain gap between two percentages. From 40% to 50% is 10 percentage points.

How is that different from a percent change?

A percent change is relative to the start. 40% to 50% is a 25% increase, because 10 is a quarter of 40.

Why does the difference matter?

An interest rate going from 4% to 5% rose one percentage point, but it is 25% more expensive. Both are true, and they mean different things.

What if the starting percentage is 0?

The points are still shown, but a relative change from 0 isn't defined, so it is left out.
