A Percentage Decrease Calculator is a tool that helps you calculate the percentage reduction between an original value and a new, lower value. It shows how much a value has decreased, expressed as a percentage of the original value.

Formula:

The formula used to calculate the percentage decrease is:

 

Percentage Decrease=(Original Value−New ValueOriginal Value)×100\text{Percentage Decrease} = \left( \frac{\text{Original Value} – \text{New Value}}{\text{Original Value}} \right) \times 100

 

Steps:

1. Enter the Original Value: This is the initial value before the decrease.
2. Enter the New Value: This is the reduced value after the decrease.
3. Calculate: The tool subtracts the new value from the original value, divides the result by the original value, and multiplies by 100 to give the percentage decrease.

Example:

If the original price of a product is $80, and the new price is $60, the percentage decrease is:

 

(80−6080)×100=25%\left( \frac{80 – 60}{80} \right) \times 100 = 25\%

 

This means the value has decreased by 25%.

Uses:

• Discounts: Determining the percentage discount on products or services.
• Price Reductions: Calculating the percentage decrease in the cost of goods.
• Financial Losses: Analyzing reductions in revenue, profits, or stock prices.
• Sales Analysis: Measuring how much sales or other metrics have dropped over time.

In summary, the Percentage Decrease Calculator is a valuable tool for anyone needing to understand reductions in values, whether in retail pricing, investments, or general financial analysis.
