Calculate Percentage Decrease Now! →The Formula for Percentage Decrease
The formula to calculate percentage decrease is as follows:
Percentage Decrease = [(Original Value - New Value) / Original Value] * 100
Let's break down what each component means:
- Original Value: The starting amount before any reduction occurred.
- New Value: The amount after the reduction.
How to Calculate Percentage Decrease: A Step-by-Step Guide
Let's walk through the steps to calculate percentage decrease, along with examples.
Step 1: Identify the Original and New Values
The first step is to identify the original value and the new value after the decrease.
Example: A product was originally priced at $80, and is now on sale for $60.
- Original Value: $80
- New Value: $60
Step 2: Calculate the Difference
Subtract the new value from the original value to find the amount of the decrease.
Using our example:
Decrease = Original Value - New Value = $80 - $60 = $20
Step 3: Apply the Formula
Divide the decrease by the original value and then multiply by 100 to get the percentage decrease.
Percentage Decrease = (Decrease / Original Value) * 100
Percentage Decrease = ($20 / $80) * 100 = 0.25 * 100 = 25%
Therefore, the percentage decrease in price is 25%.
Real-World Examples of Percentage Decrease
Let's explore some practical examples where calculating percentage decrease can be useful.
- Sales Discounts: If a store marks down a $150 item to $120, the percentage decrease is (($150 - $120) / $150) * 100 = 20%. This tells you the item is 20% off.
- Weight Loss: If someone's weight decreases from 200 lbs to 180 lbs, the percentage decrease is ((200 - 180) / 200) * 100 = 10%. This indicates a 10% weight loss.
- Business Revenue: If a company's revenue decreases from $500,000 to $400,000, the percentage decrease is (($500,000 - $400,000) / $500,000) * 100 = 20%. This shows a 20% drop in revenue.
These examples illustrate how percentage decrease can be applied in different scenarios to understand relative changes.
