1. What is a Percentage Reduction Calculator?

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

Purpose: It helps quantify decreases in values 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 values is divided by the original value and multiplied by 100 to get the percentage reduction.

3. Importance of Percentage Reduction Calculation

Details: This calculation is crucial for analyzing cost savings, performance improvements, efficiency gains, and other comparative metrics.

4. Using the Calculator

Tips: Enter the original value and new value (both unitless numbers). The original value must be greater than 0.

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 is greater than 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: The calculation is undefined (division by zero), so the calculator requires original > 0.

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

Q5: Can I compare reductions across different scales?
A: Yes, percentages allow comparison regardless of the original magnitude.
