Percentage Point Calculator
Find the percentage point (pp) difference between two percentage values and the relative percentage change. Enter an original rate and a new rate to see how many percentage points it shifted and by what relative percentage the rate itself changed.

Old rate

New rate

Relative % change
(7 − 5) ÷ |5| × 100 = 40 - 4
Percentage point change
7 − 5 = 2
How does this calculator work?
Percentage point change = New% − Old% (simple subtraction). Relative % change = (New% − Old%) ÷ Old% × 100. A rate rising from 5% to 7% is +2 pp but +40% relative change — completely different numbers describing the same move.
Formula
How this is calculated
A percentage point is the arithmetic difference between two percentages. If an interest rate rises from 5% to 7%, it has increased by 2 percentage points — a simple subtraction, independent of the original value. This is fundamentally different from saying the rate increased by 40% (the relative change: 2 ÷ 5 × 100 = 40%).
The confusion between percentage points and percentage change is one of the most common numerical errors in reporting. "The unemployment rate fell from 8% to 6%" is a 2 percentage point drop, but a 25% relative decrease. Media reports often omit "percentage points" and just say "percent," which can be misleading. The two measures answer different questions: percentage points tell you the raw arithmetic shift; relative percentage change tells you how large that shift is compared to the original rate.
This calculator computes both. The relative change is undefined when the original rate is zero (division by zero), in which case only the percentage point change is reported.
Frequently asked questions
A percentage point (pp) is the arithmetic difference between two percentages. If a rate goes from 5% to 7%, that is a 2 percentage point increase — regardless of the starting value.
Percentage points are absolute: 7% − 5% = 2 pp. Percent change is relative: (7 − 5) ÷ 5 × 100 = 40%. Both are correct descriptions of the same move, but they answer different questions and can differ dramatically in magnitude.
Use percentage points when comparing rates or proportions directly (interest rates, poll results, tax rates, pass rates). Use relative percent change when describing how large the shift is compared to the original level — for example, "the tax rate nearly doubled" versus "it rose by 3 percentage points."
