A percentage increase calculator measures how much a value has grown, expressed as a percentage of where it started. It's handy for price rises, population growth and score improvements.
Increase % = (new − original) ÷ original × 100
The increase amount is simply the new value minus the original. Dividing by the original and multiplying by 100 turns it into a percentage.
A percentage increase from zero is undefined (division by zero), so the result shows as a dash. Any increase from zero is an infinite percentage gain.
Percentage change is the same formula but keeps its sign, so it covers both increases and decreases. This calculator focuses on the increase case for clarity.
