What it does

Change = (new − original) ÷ |original| × 100. The absolute baseline makes the sign show increase or decrease.

Worked example

80 → 100 = 25% increase.

The example demonstrates the operation. For file-based tools, results depend on the selected file and options.

How the result is produced

Change = (new − original) ÷ |original| × 100. The absolute baseline makes the sign show increase or decrease.

Important limits

A zero baseline is undefined. Negative baselines use the absolute-baseline convention.

Choosing the next step

Enter values in the units and convention named by the page, then compare the displayed formula with your question. For money, change the assumptions rather than treating an estimate as an offer; for statistics, decide whether the data represents a sample or a full population.
