What is the percentage decrease?
The percentage decrease measures the decline of a value relative to its starting point. It is commonly used for clearance sales (discounts), loss of value, or decreasing stock levels.
The Formula
To calculate the percentage reduction, we use the following formula:
[(Starting value - Ending value) / Starting value] × 100
Step-by-step Explanation
The calculation is carried out in three simple steps:
- Subtract: Subtract the final (lower) value from the initial value.
- Divide: Divide the difference by the original starting value.
- Convert: Multiply the result by 100.
Example
If a price drops from 120 € to 90 €:
- Difference: 120 - 90 = 30
- Division: 30 / 120 = 0.25
- Result: 0.25 × 100 = 25% decrease.
