2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• New — Result after percentage decrease
• Original — Starting value before decrease
• % — Percentage to decrease (0-100)

Explanation: The percentage is converted to a decimal (divided by 100) and subtracted from 1 to get the multiplier for the original value.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage decrease and subtraction?
A: Percentage decrease is multiplicative (relative to the original value), while subtraction is a fixed amount regardless of the original value.

Q2: Can I use this for price discounts?
A: Yes, this is perfect for calculating sale prices after applying a discount percentage.

Q3: What happens if I enter 100% decrease?
A: The result will be zero, as 100% decrease means completely removing the original value.

Q4: How do I calculate percentage increase instead?
A: Use our Percentage Increase Calculator or change the formula to (1 + %/100).

Q5: Why does 10% decrease followed by 10% increase not return to original?
A: Because percentage changes are relative to the current value, not the original. This is called percentage point difference.
