How Does Percent Change Calculator Work?
Percent change can be applied to any quantity. The percent change can be both a positive and a negative value. A positive value indicates that the quantity has increased over a period of time. Similarly, a negative value shows that the quantity has decreased in a given time period. The concept of percentage change is widely used in the field of finance. Banks use the percent change to track the price of a security. Further, percentage change is also used to compare the prices of various currencies. The steps to calculate the percent change between an old value and a new value are as follows:
- Subtract the initial value of a quantity from its final value.
- Divide the value obtained in step 1 by the initial value.
- Multiply the result by 100 to get the percent change.
The percent change is calculated using the formula:
Percent change = ((Final value - Initial value) / initial value) × 100
Solved Examples on Percent Change Calculator
Example 1:
Find the percent change if 70 is increased to 150 and verify it using the percent calculator.
Solution:
Given: Initial value = 70, Final value = 150
Percent change = ((Final value - Initial value) / initial value) × 100
= ((150 - 70) / 70) × 100
= (80 / 70) × 100
= 1.142 × 100%
= 114.28%
Since the answer is positive, it is a percent increase.
Example 2:
Find the percent change if a quantity goes from 90 to 20 and verify it using the percent calculator.
Solution:
Given: Initial value = 90, Final value = 20
Percent change = ((Final value - Initial value) / initial value) × 100
= ((20 - 90) / 90) × 100
= (-70 / 90) × 100
= -0.7778 × 100
= -77.78%
Since the answer is negative, it is a percent decrease.
Similarly, you can try the percent change calculator to find the percent change for the following values.
- Initial value = 180, Final value = 250
- Initial value = 120, Final value = 100
