Calculate Percentage Decrease Now →What is Percentage Decrease?
Percentage decrease represents the extent of reduction in value, expressed as a percentage of the initial value. It is particularly useful when evaluating the significance of a change. For instance, a 30% price drop carries more weight than a simple dollar amount reduction.
The Percentage Decrease Formula
To calculate percentage decrease, use the following formula:
Percentage Decrease = [(Original Value - New Value) / Original Value] x 100
This formula provides the percentage by which the original value has decreased to reach the new value.
Steps to Calculate Percentage Decrease
- Determine the Original and New Values: Identify the starting value and the ending value after the decrease.
- Calculate the Amount of Decrease: Subtract the New Value from the Original Value.
- Divide by the Original Value: Divide the result from Step 2 by the Original Value.
- Multiply by 100: Multiply the result from Step 3 by 100 to express it as a percentage.
Percentage Decrease Example Scenarios
Let's explore percentage example situations to illustrate the concept:
-
Scenario 1: Sales Drop
A store's sales decreased from $500 last week to $400 this week. What is the percentage decrease in sales?
- Amount of Decrease: $500 - $400 = $100
- Percentage Decrease: ($100 / $500) x 100 = 20%
- Sales have decreased by 20%.
-
Scenario 2: Price Discount
A product's price was reduced from $80 to $60. Calculate the percentage discount.
- Amount of Decrease: $80 - $60 = $20
- Percentage Decrease: ($20 / $80) x 100 = 25%
- The product has a 25% discount.
-
Scenario 3: Weight Loss
A person's weight decreased from 200 lbs to 180 lbs. Find the percentage weight loss.
- Amount of Decrease: 200 lbs - 180 lbs = 20 lbs
- Percentage Decrease: (20 lbs / 200 lbs) x 100 = 10%
- The person experienced a 10% weight loss.
-
Scenario 4: Reduced Work Hours
An employee's work week was reduced from 40 hours to 32 hours. What is the percentage decrease in work hours?
- Amount of Decrease: 40 hours - 32 hours = 8 hours
- Percentage Decrease: (8 hours / 40 hours) x 100 = 20%
- The employee experienced a 20% reduction in work hours.
Negative Percentage Decrease: A Rate of Increase
If the calculation results in a negative percentage decrease, it actually indicates a percentage increase. This often occurs when the initial and final values are mistakenly swapped. Always double-check your figures to ensure accurate results. If you see that you are getting a negative number, then you need to calculate percentage increase formula.
