Purpose: It helps analyze reductions in quantities like prices, measurements, or performance metrics.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Original \) — The starting value before decrease
• \( New \) — The value after decrease

Explanation: The difference between original and new values is divided by the original value, then multiplied by 100 to convert to percentage.

3. Importance of Percent Decrease Calculation
