Separate absolute difference, relative percentage change and percentage-point change. Zero and negative baselines are explained.

Outputs are cleared when the input changes.
Result
Enter your data or use the example, then run the tool.
Worked example
100 to 120 has an absolute increase of 20 and relative increase of 20%.
20% to 25% is +5 percentage points, while the relative increase is 25%.
Method
Subtract original from new for the absolute difference. For a positive original, divide this difference by original and multiply by 100.
When the inputs represent percentages, their numeric difference is separately labelled in percentage points.
Limits
Zero baselines have no defined relative percentage change. Negative baselines only show an absolute difference and a caution.
Finite decimal inputs only; results are floating-point approximations. No statistical significance, causal effect or investment return is inferred. Each input’s magnitude is at most 10^150; overflowed changes are rejected.
