🔢 What Is Percentage Decrease?

Percentage decrease is the rate at which a number goes down from its original value, shown as a percentage. It tells you how much a value has fallen compared to where it started and is commonly used in business, finance, statistics, and everyday calculations.

📐 Percentage Decrease Formula

Percentage Decrease = (Original Value - New Value) / Original Value × 100

This formula calculates the difference between the original and the new value, then expresses that reduction as a percentage of the original.

✍️ Example Calculation:

Suppose the price of an item dropped from $120 to $90.

(120 - 90) / 120 × 100 = 30 / 120 × 100 = 25%
✅ So, the percentage decrease is 25%
