Percentage vs. Percentage Point: The Difference That Costs People Money

You'll see both phrases in the news: "interest rates rose by 2 percent" and "interest rates rose by 2 percentage points." They sound interchangeable. They aren't — and the gap between them can be enormous.

The definitions

A percentage point is the plain arithmetic difference between two percentages. If a rate goes from 4% to 6%, that's a rise of 2 percentage points — you just subtract. A percentage change, by contrast, measures that move relative to the starting value. Going from 4% to 6% is a 50% increase, because the 2-point rise is half of the original 4.

Why it matters

Both statements describe the same event, but they'll mislead you if you mix them up. Imagine a headline says a tax rate is "increasing by 50%." If the rate was 20%, a 50% relative increase takes it to 30% — a 10 percentage-point jump. But a careless reader might think it's rising to 70%. The wording changes the meaning completely.

A finance example

Suppose a savings account pays 2% interest and the bank raises it to 3%. That's a 1 percentage-point increase, which sounds modest. But it's also a 50% increase in your interest earnings — quite significant if you're the saver. Reporting it as "1 point" and "50%" are both accurate; they just emphasise different things.

How to keep them straight

Use "percentage points" whenever you're describing the gap between two percentages directly. Use "percent" when you're describing how much one value grew relative to another. When you read a statistic, ask yourself which one is meant — the honest sources say "percentage points" precisely to avoid the ambiguity.

The takeaway

Whenever percentages describe other percentages — interest rates, poll numbers, tax bands, unemployment figures — watch for this distinction. It's one of the easiest ways for a true number to create a false impression.
