1. What is Percent Reduction?

Percent reduction measures the decrease in a value relative to its original amount, expressed as a percentage. It's commonly used to track performance improvements, cost savings, or efficiency gains.

2. How Does the Calculator Work?

The calculator uses the percent reduction formula:

Where:

• \( Old \) — Original value
• \( New \) — New value after reduction

Explanation: The formula calculates the difference between old and new values, divides by the original value, and converts to percentage.

3. Importance of Percent Reduction

Details: Percent reduction is widely used in business, finance, science, and engineering to quantify improvements, savings, or changes in performance metrics.

4. Using the Calculator

Tips: Enter both old and new values. The old value must be greater than zero. The new value should be less than or equal to the old value for reduction calculations.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percent reduction mean?
A: A negative result indicates an increase rather than a reduction (new value is greater than old value).

Q2: How is percent reduction different from percentage points?
A: Percent reduction measures change relative to the original value, while percentage points measure absolute difference between percentages.

Q3: What's the maximum possible percent reduction?
A: The maximum is 100% reduction, which occurs when the new value reaches zero.

Q4: Can I use this for price reductions?
A: Yes, this calculator works for calculating price discounts, cost savings, or any similar reductions.

Q5: How should I interpret a 50% reduction?
A: A 50% reduction means the new value is half of the original value.
