Percentage Points Difference Calculator
Compare two percentages the right way — the gap in percentage points versus the relative percent change between them.
How it works
Percentage points = p₂ − p₁ · Relative change = (p₂ − p₁) ÷ |p₁| × 100
Percentages of percentages confuse almost everyone. When a rate moves from 45% to 60%, that is a rise of 15 percentage points — but it is a 33% relative increase, because 15 is a third of the original 45. Percentage points measure the raw gap; percent change measures the gap relative to the starting rate. News headlines routinely mix these up.
Worked example
A poll moving from 45% to 60% support has risen 60 − 45 = 15 percentage points. Relative to the original 45%, that same 15 is 15 ÷ 45 = 33.3%, so it is also a 33.3% relative increase.

Frequently asked questions
What is the difference between a percentage point and a percent?
A percentage point is the arithmetic gap between two percentages (45% to 60% is 15 points). A percent change scales that gap against the starting value (15 out of 45 is a 33% increase). Both describe the same move but answer different questions.
When should I quote percentage points instead of percent?
Use percentage points when both numbers are already percentages — interest rates, poll shares, tax rates. It avoids the ambiguity of “rates rose 50%,” which could mean 50 points or a 50% relative jump.
