Percentage Point Change Calculator
Separate direct percentage-point movement from relative percent and basis-point changes.
What would you like to do next?
Keep percentage points and percent change distinct
Enter an original rate and a new rate, both expressed as percentages. The calculator subtracts them directly to show percentage-point movement, converts that difference to basis points and also calculates relative percent change using the original rate. Seeing all three forms together helps avoid statements such as calling a move from ten to twelve percent a two-percent increase.
Name the measure when communicating a result
A rise from ten to twelve percent is two percentage points, two hundred basis points and a twenty-percent relative increase. Each description is valid but answers a different question. When the original rate is zero the relative percentage change is undefined, although the point and basis-point differences remain available.
Frequently asked questions
What is one percentage point?
It is the direct difference of one between two percentage rates.
How many basis points are in one percentage point?
One percentage point equals 100 basis points.
Why can relative change be undefined?
It divides by the original rate, so an original rate of zero has no defined relative result.
