Percentage Increase vs. Percentage Points: What's Actually Different
A percentage point measures the raw difference between two percentages (25% − 20% = 5 percentage points), while a percentage increase measures the relative change (5 is 25% of the original 20%, so it's a 25% increase) — the two describe the same change with very different-looking numbers, and conflating them is a common source of confusion, especially in news and statistics.
This distinction shows up constantly in interest rates, survey results, and news reporting, and mixing the two up can make a change sound much bigger or smaller than it actually is.
A worked comparison
An interest rate moves from 4% to 5%. In percentage points, that's a 1 percentage point increase — a small, precise description of the raw gap. As a percentage (relative) increase, that same move is a 25% increase (1 is 25% of the original 4) — a much larger-sounding number describing the same underlying change.
Why this matters for interpretation
Both descriptions are accurate, but they emphasize different things — percentage points describe absolute magnitude, while percentage change describes relative magnitude. A headline saying rates "jumped 25%" and one saying rates "rose 1 percentage point" are describing the identical event, and knowing which framing is being used is necessary to correctly judge how significant a change actually is.
