About the Percentage Change Calculator

Percentage Change is treated here as a quantitative relation between Original Value and New Value and Percentage Change, Absolute Change and Direction.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
Percentage Change = ((New Value - Old Value) / |Old Value|) x 100

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

Percentage Change = ((New Value - Old Value) / |Old Value|) x 100

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Salary Raise

Inputs

old_value: 55000 new_value: 61600
Percentage Change: 12%. Absolute Change: 6,600. Direction: Increase

With Original Value = 55,000 and New Value = 61,600 as the stated inputs, the result is Percentage Change = 12%, Absolute Change = 6,600 and Direction = Increase. Each value corresponds to the declared output fields.

Example 2: Stock Price Drop

Inputs

old_value: 148.5 new_value: 121.77
Percentage Change: -18%. Absolute Change: -26.73. Direction: Decrease

With Original Value = 148.5 and New Value = 121.77 as the stated inputs, the result is Percentage Change = -18%, Absolute Change = -26.73 and Direction = Decrease. Each value corresponds to the declared output fields.

Example 3: Home Price Appreciation

Inputs

old_value: 320000 new_value: 374400
Percentage Change: 17%. Absolute Change: 54,400. Direction: Increase

With Original Value = 320,000 and New Value = 374,400 as the stated inputs, the result is Percentage Change = 17%, Absolute Change = 54,400 and Direction = Increase. Each value corresponds to the declared output fields.

Example 4: Calorie Reduction

Inputs

old_value: 2800 new_value: 2100
Percentage Change: -25%. Absolute Change: -700. Direction: Decrease

With Original Value = 2,800 and New Value = 2,100 as the stated inputs, the result is Percentage Change = -25%, Absolute Change = -700 and Direction = Decrease. Each value corresponds to the declared output fields.
