How the percentage point change calculator works
Percentage-point change = ending percentage − starting percentage. Relative percent change = difference ÷ absolute starting rate × 100.
Check your measurements and assumptions
Percentage points describe the direct difference between two rates. Relative percent change describes the size of that difference compared with the starting rate.
Review the estimate before you act
Compare this result with an independent measurement, supplier quote or institution guidance when the decision matters.
