2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Original — The initial value before decrease
• New — The value after decrease

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

3. Importance of Percent Decrease Calculation

Q2: Can I use this for price reductions?
A: Yes, this is commonly used to calculate discount percentages.

Q3: What's the maximum possible decrease?
A: The maximum is 100% when the new value reaches zero.

Q4: How is this different from percentage change?
A: Percentage change can be positive or negative, while decrease only shows reduction.

Q5: What units should I use?
A: The calculator is unitless - use consistent units for both values.
