Percentage Decrease Calculator
The Percentage Decrease Calculator helps you determine how much a value has decreased from its original amount. It calculates both the decrease amount and the percentage decrease, making it useful for tracking discounts, price reductions, depreciation, business performance, budgeting, and financial analysis.
What Is Percentage Decrease?
Percentage decrease measures how much a value has fallen compared to its original amount. The decrease is expressed as a percentage of the starting value, allowing you to compare reductions across different numbers.
Formula
Percentage Decrease = ((Original Value − New Value) ÷ Original Value) × 100
- Original Value = Starting amount
- New Value = Ending amount
- Decrease = Original Value − New Value
Example 1
A product's price drops from $200 to $150.
Decrease = 200 − 150 = 50
Percentage Decrease = (50 ÷ 200) × 100 = 25%
Example 2
A company's monthly sales decrease from $50,000 to $42,500.
Decrease = 7,500
Percentage Decrease = (7,500 ÷ 50,000) × 100 = 15%
