How Does Percentage Decrease Calculator Work?
The percent change formula is used to check if there has been a percentage increase or a percentage decrease in the given quantity. If the percentage change results in a positive number, it indicates that the quantity has increased. In such a case the final value is greater than the initial value. However, if the percent change is a negative number, it means that the quantity has decreased over time. The final value is lesser than the initial value in this case. The percentage decrease formula is only used in situations when we know that there has been a depreciation in the value of the quantity. The steps to find the percentage decrease are as follows:
- Step 1: Subtract the final or decreased value of the quantity from the initial value.
- Step 2: Divide the answer from step 1 by the initial value.
- Step 3: To express this value as a percentage, multiply the result of step 2 by 100.
The Percentage Decrease Formula is given as:
Percentage Decrease = [(Initial value - Final or Decreased Value) / Initial Value] × 100.
Solved Examples on Percentage Decrease Calculator
Example 1:
There was a new years' discount sale and the price of a dress was decreased from 25 USD to 20 USD. Find the percentage decrease in the price of the dress and verify it using the percentage decrease calculator.
Solution:
Initial Price = 25 USD
Reduced Price = 20 USD
Percentage Decrease = [(Initial value - Decreased value) / Initial value] × 100
= [(25 - 20) / 25] × 100
= 5 / 25 × 100
= 20 %
Therefore, the price of the dress decreased by 20 %.
Example 2:
The price of earrings decreased from 92.5 USD to 78.2 USD during a Black Friday sale. Find the percentage decrease in the price of the earrings and verify it using the percentage decrease calculator.
Solution:
Initial Price = 92.5 USD
Reduced Price = 78.2 USD
Percentage Decrease = [(Initial value - Decreased value) / Initial value] × 100
= [(92.5 - 78.2) / 92.5] × 100
= 14.3 / 92.5 × 100
= 15.459 %
Therefore, the price of the earrings decreased by 15.459 %.
