How Percentage Decrease is Calculated

The Percentage Decrease Calculator determines the reduction from an initial value to a final value, expressed as a percentage of the initial value.

Percentage Decrease Formula

$$ \text{Percentage Decrease} = \frac{\text{Starting Value} – \text{Final Value}}{|\text{Starting Value}|} \times 100 $$

Steps to Calculate:

  1. Subtract the Final Value from the Starting Value to find the absolute change.
  2. Divide the change amount by the absolute value of the Starting Value.
  3. Multiply the result by $100$ to convert the decimal ratio into a percentage.

Note: If the result is a negative percentage, it indicates a percentage *increase* rather than a decrease.
