1. What is a Percentage Reduction Calculator?

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

Purpose: It helps quantify reductions in various contexts like prices, quantities, measurements, or performance metrics.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Original \) — The starting or baseline value
• \( New \) — The reduced or current value

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

3. Importance of Percentage Reduction Calculation

Details: This calculation is essential for analyzing changes in business metrics, price discounts, weight loss, energy savings, and many other applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use this for percentage increase?
A: Yes, when new > original, the result will be negative, representing an increase.

Q3: What if my original value is zero?
A: Division by zero is undefined. Original must be greater than zero.

Q4: How precise are the results?
A: Results are calculated to 2 decimal places for percentage values.

Q5: Can I compare different reductions?
A: Yes, percentage reduction allows standardized comparison across different scales.
