Did it go from 5 percent to 5.25 percent (a 5 percent increase of the rate), or from 5 percent to 10 percent (a 5 percentage point increase)? Those are wildly different, and the confusion between percentage change and percentage points is one of the most common ways numbers mislead, sometimes by accident, sometimes on purpose. Here is the difference, made permanent with examples.

The Two Things Being Measured
The confusion exists because we are measuring change in something that is itself already a percentage. There are two valid ways to express that change:
- Percentage points: the simple arithmetic difference between two percentages. From 5 percent to 10 percent is a rise of 5 percentage points. You just subtract.
- Percentage change: the relative change, how big the increase is compared to the starting value. From 5 percent to 10 percent is a 100 percent increase, because 10 is double 5.
Both describe the same move from 5 to 10. One says "+5 points," the other says "+100 percent." Neither is wrong; they answer different questions.
The Canonical Example
An interest rate goes from 2 percent to 3 percent.
- In percentage points: it rose by 1 percentage point (3 minus 2).
- In percentage change: it rose by 50 percent (the increase of 1 is half of the starting 2).
A news headline saying "interest rates jump 50 percent" sounds alarming. "Interest rates rise 1 percentage point" sounds measured. Both describe the identical change. This is exactly why you see each phrasing chosen depending on what impression the writer wants to create.
How to Calculate Each
Percentage points (the easy one)
Subtract the old percentage from the new percentage. From 40 percent to 55 percent is a rise of 15 percentage points. That is the whole calculation.
Percentage change (the relative one)
Take the difference, divide by the original value, multiply by 100. From 40 percent to 55 percent: the difference is 15, divided by the original 40 is 0.375, times 100 is a 37.5 percent increase. A percentage calculator does this instantly, but knowing the formula lets you catch when a number is being spun.
Where This Confusion Does Real Damage
Interest rates and loans
A mortgage rate moving from 6 percent to 7 percent is 1 percentage point, but it is a 16.7 percent increase in the rate, and it can raise your monthly payment substantially. Describing it either way is accurate, but only modeling the actual payment with a loan calculator tells you what it costs you.
Polls and approval ratings
"Support fell 4 percent" is ambiguous. If support went from 48 percent to 44 percent, that is a 4 percentage point drop but an 8.3 percent relative decline. Careful reporting says "percentage points" for poll movements; sloppy or slanted reporting blurs it.
Advertising and statistics
"Our cream reduces wrinkles by 30 percent" versus "by 30 percentage points" can mean very different things, and the vaguer phrasing is usually chosen to sound bigger. Whenever a percentage describes a change in something that is already a rate, ask which one they mean.
Business metrics
A conversion rate going from 2 percent to 4 percent is 2 percentage points but a 100 percent improvement (it doubled). A team reporting "we doubled conversion" and a skeptic saying "it only moved 2 points" are both right; they are choosing the framing that suits their argument.
How to Read These Numbers Defensively
- When you see a percentage describing change in a rate, ask: points or relative? If the source does not say, you cannot fully trust the number.
- Watch for the bigger-sounding framing. Relative change (percentage) usually sounds larger for small base rates; points sound more modest. The choice often signals intent.
- Convert to absolute terms when it matters. For money, do not stop at the percentage; calculate the actual dollar effect. A rate change's real impact is the payment difference, not the percentage label.
- Be precise in your own writing. Say "percentage points" when you mean the arithmetic difference. It removes ambiguity and signals you know the distinction.
The Bottom Line
Percentage points are the plain subtraction between two percentages; percentage change is the relative size of the move compared to the start. A rate going from 5 to 10 rose 5 percentage points and 100 percent, both true. The confusion is a favorite tool for making changes sound bigger or smaller than they are. Whenever a percentage describes a change in something already measured as a percent, pause and ask which one is meant, and for anything involving money, calculate the actual amount so the label cannot mislead you.
Frequently Asked Questions
What is the difference between percentage points and percentage change?
Percentage points are the simple arithmetic difference between two percentages: 5 percent to 10 percent is a rise of 5 percentage points. Percentage change is the relative size of the move compared to the starting value: 5 percent to 10 percent is a 100 percent increase because 10 is double 5. Both describe the same change but answer different questions.
How do I calculate percentage change between two percentages?
Take the difference between the new and old values, divide by the original value, then multiply by 100. Going from 40 percent to 55 percent: the difference is 15, divided by the original 40 gives 0.375, times 100 is a 37.5 percent increase. To get percentage points instead, you simply subtract: 55 minus 40 is 15 percentage points.
Why does the difference between the two matter?
Because the same change can be framed to sound large or small. An interest rate going from 2 to 3 percent is a modest-sounding 1 percentage point but an alarming-sounding 50 percent increase. News, ads, and business reports often pick whichever framing suits their message, so confusing the two lets numbers mislead you, especially with money where the real impact is the dollar amount.
When a poll says support fell 4 percent, what does that mean?
It is ambiguous unless the source specifies. If support went from 48 percent to 44 percent, that is a 4 percentage point drop but an 8.3 percent relative decline. Careful reporting uses percentage points for poll movements. If a source just says percent without clarifying, you cannot tell which it means, which is itself a reason to be cautious with the number.
How should I describe a rate change in my own writing?
Say percentage points when you mean the arithmetic difference between two percentages, and reserve percent or percentage change for the relative move. Being explicit removes ambiguity and signals you understand the distinction. When the change involves money, also give the absolute figure, like the actual payment difference, so readers are not misled by the percentage label alone.
