Formula and methodology
Formula: Signed change = new value − original value; percentage change = signed change/original value × 100.
The calculator keeps the direction of change visible and uses the original value as the reference denominator.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Original value — minimum -1000000000; maximum 1000000000
- New value — minimum -1000000000; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Original value | 100 |
| New value | 125 |
Change = 25; percentage change = 25%.
Assumptions and limits
- The original value is nonzero because it is the percentage-change reference.
- Values share one unit and the sign is meaningful for the supplied quantity.
- This is arithmetic and does not infer whether a change is favorable or significant.
