Formula and methodology
Formula: Change = new − original; percentage increase = change/original × 100.
The percentage uses the original value as its baseline, so a sign and a zero baseline matter.
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 | 80 |
| New value | 100 |
Change = 20; percentage increase = 25%.
Assumptions and limits
- The original value is not zero.
- The result is a signed comparison; a negative result means the new value is lower.
- Both values use the same unit.
