1. What is a Percentage Decrease Calculator?

Definition: This calculator determines the percentage decrease between an original value and a new value.

Purpose: It helps quantify reductions in values like prices, quantities, or measurements as a percentage change.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Original — The initial value before decrease
• New — The value after decrease
• Decrease — The percentage reduction from original to new value

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

3. Importance of Percentage Decrease Calculation

Details: Percentage decrease is widely used in finance, economics, business analysis, and scientific measurements to quantify changes.

4. Using the Calculator

Tips: Enter the original value and new value (must be less than original). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative result mean?
A: A negative result indicates a percentage increase rather than decrease (new value > original value).

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

Q3: How is this different from percentage change?
A: Percentage decrease only shows reductions, while percentage change can show either increases or decreases.

Q4: What's the maximum percentage decrease possible?
A: The maximum is 100%, which occurs when the new value is zero.

Q5: Why multiply by 100 in the formula?
A: This converts the decimal result to a percentage (e.g., 0.25 becomes 25%).
