Subtract two percentage rates to find their absolute movement. Enter the two values below. The result panel shows the calculation used, and the examples explain how to interpret it.
How to use the percentage points calculator
- Identify the values required by the input labels.
- Enter percentages as whole-number rates: 15 means 15%.
- Select Calculate and read the result together with its formula.
- Check the assumptions below before applying the answer to a real situation.
Formula and method
Worked example
A survey result rises from 30% to 36%. Subtract the rates: 36 − 30 = 6 percentage points. For the relative increase, divide that 6 by the original 30 and multiply by 100: 20%.
A move from 1% to 2% is one percentage point and a 100% relative increase. Both statements describe the same move. The distinction matters because a large relative percentage can accompany a small absolute movement.
Write the comparison clearly
State both the original and new rate, then name the unit. For example: “The completion rate increased from 70% to 77%, a rise of seven percentage points.” If relative growth is relevant, add that it increased by 10% relative to its original level.
Example calculations
| Original rate | New rate | Point change |
|---|---|---|
| 20% | 25% | +5 pp |
| 8% | 6% | −2 pp |
| 50% | 50% | 0 pp |
| 1% | 2% | +1 pp |
Input rules and limitations
Enter the rates as percentages, such as 20 and 25, rather than 0.20 and 0.25. The output unit is percentage points (pp), not a relative percentage change.
Display precision can be changed from two to eight decimal places. Intermediate values are not rounded, but the calculation uses standard browser floating-point arithmetic. Currency figures should be rounded according to the rules relevant to your actual transaction.
Common questions
Does the result include units?
The calculator works with numbers. Keep the same units for comparable quantities and add the appropriate unit when reporting the result.
Why does the calculator reject some inputs?
Enter the rates as percentages, such as 20 and 25, rather than 0.20 and 0.25. The output unit is percentage points (pp), not a relative percentage change.

Choose the right comparison
Use the percentage change calculator for an original-to-new comparison, the percentage difference calculator when neither value is the baseline, and the percentage points calculator to subtract rates. You can also return to the main percentage calculator.
