1. What is the Decrease By Percentage Calculator?

The Decrease By Percentage Calculator calculates the new value after applying a percentage decrease to an original value. This is useful for calculating discounts, depreciation, or any situation where a value decreases by a certain percentage.

2. How Does the Calculator Work?

The calculator uses the percentage decrease formula:

Where:

• \( Old \) — Original value before decrease
• \( \% \) — Percentage decrease (0-100)
• \( New \) — Resulting value after decrease

Explanation: The formula multiplies the original value by (1 - percentage/100) to find the reduced value.

3. Importance of Percentage Decrease Calculation

Details: Calculating percentage decreases is essential in finance, retail, economics, and many other fields where understanding value reduction is important.

4. Using the Calculator

Tips: Enter the original value and the percentage decrease (between 0-100). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage decrease and absolute decrease?
A: Percentage decrease is relative to the original value, while absolute decrease is the simple difference between old and new values.

Q2: How do I calculate the percentage decrease between two values?
A: Use: ((Old - New)/Old) × 100%. This calculator does the reverse - finds New given Old and % decrease.

Q3: Can I use this for increases by changing the sign?
A: No, this calculator is specifically for decreases. For increases, you would need a different formula.

Q4: What if I enter a percentage greater than 100%?
A: The calculator limits percentage input to 0-100% as decreases beyond 100% would result in negative values.

Q5: How precise are the calculations?
A: Results are rounded to 4 decimal places for practical use while maintaining reasonable precision.
