How to use Percentage Points Calculator
Subtract the original percentage rate from the new rate to obtain percentage points. The relative change divides this difference by the original rate.
- Enter original rate (%), new rate (%).
- Check that the input follows the stated limits and uses consistent units.
- Run the calculator, review the result, then copy or download it.
Good to know
- Rates are entered as percentages, such as 20 rather than 0.2. Relative change is not defined when the starting rate is zero.
- Decimal inputs have at most 120 characters and magnitude from 1e-100 to 1e15, or zero. Floating-point results are rounded to 12 significant digits; extreme derived results may underflow or be rejected. Exact integer results are identified separately.
Common questions
What calculation does Percentage Points Calculator perform?
Subtract the original percentage rate from the new rate to obtain percentage points. The relative change divides this difference by the original rate.
Can rates exceed 100%?
Yes. This compares numeric rates without assuming that each is a share of a whole.
