About the Percentage Difference Calculator

Percentage Difference is treated here as a quantitative relation between Value A and Value B and Percentage Difference, Absolute Difference and Average of A and B.

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 Difference = |A - B| / ((A + B) / 2) 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 Difference = |A - B| / ((A + B) / 2) 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: Comparing Two Job Offers

Inputs

value_a: 72000 value_b: 85000
Percentage Difference: 16.5605%. Absolute Difference: 13,000. Average of A and B: 78,500

With Value A = 72,000 and Value B = 85,000 as the stated inputs, the result is Percentage Difference = 16.5605%, Absolute Difference = 13,000 and Average of A and B = 78,500. Each value corresponds to the declared output fields.

Example 2: Grocery Price Comparison

Inputs

value_a: 3.49 value_b: 2.89
Percentage Difference: 18.8088%. Absolute Difference: 0.6. Average of A and B: 3.19

With Value A = 3.49 and Value B = 2.89 as the stated inputs, the result is Percentage Difference = 18.8088%, Absolute Difference = 0.6 and Average of A and B = 3.19. Each value corresponds to the declared output fields.

Example 3: Comparing Survey Results

Inputs

value_a: 68 value_b: 74
Percentage Difference: 8.4507%. Absolute Difference: 6. Average of A and B: 71

With Value A = 68 and Value B = 74 as the stated inputs, the result is Percentage Difference = 8.4507%, Absolute Difference = 6 and Average of A and B = 71. Each value corresponds to the declared output fields.

Example 4: Blood Glucose Readings

Inputs

value_a: 112 value_b: 127
Percentage Difference: 12.5523%. Absolute Difference: 15. Average of A and B: 119.5

With Value A = 112 and Value B = 127 as the stated inputs, the result is Percentage Difference = 12.5523%, Absolute Difference = 15 and Average of A and B = 119.5. Each value corresponds to the declared output fields.
