Percentage Change Formula:

Percentage Change=New Value−Old ValueOld Value×100\text{Percentage Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100

New Value = The current or final value

Old Value = The original or initial value

Interpreting Results:

  • Positive % = Increase (new value is higher)
  • Negative % = Decrease (new value is lower)
  • 0% = No change (values are equal)

Example:

If a product's price increases from $50 to $65:

Percentage Change = ((65 - 50) / 50) × 100 = +30%
