Percentage points (absolute move)

Points measure the arithmetic difference between two percentages: 5% − 3% = 2 percentage points.

Percent change (relative move)

Percent change compares new to old: (5 − 3) ÷ 3 ≈ 66.7% increase. This answers “how much bigger relative to before?”

Why it matters

Interest rates, tax rates, and survey statistics often report point moves. Growth metrics often report percent change. Using the wrong phrase exaggerates or understates reality.

Frequently Asked Questions

Which should I put in a headline?

Use “percentage points” for rate moves; use “percent” for relative growth — and define your baseline.

Can both be reported together?

Yes. Example: “The rate rose 2 percentage points, a 66.7% increase from the prior 3%.”
