# Increase or Decrease by Percentage Percentage help make comparisons between different amounts. Simply put, a portion is a fractional quantity represented as a percentage of 100. This suggests that it is the complete item if anything is said to be 100% of something.

If you need to know how small a specific amount has grown or shrunk over time, you may easily compare the two by mentioning the corresponding percentages instead of the raw figures. Percentage calculator is also the best tool to find any share value.

Increase by Percentage

Finding the difference between the starting and ending points is also the first step in comparing the growth of a number through time. With this difference, we can

also, calculate the percentage increase in the baseline number.

Diminution in Percentage

Finding the difference between the starting and ending points is also the first step in evaluating a quantity’s decline rate over time. Next, we also compare this new number with the old one and utilize the resulting percentage to indicate the degree to which the new value is lower.

Examples of a Percentage Rise or fall

• Here’s a first illustration:

Suresh’s pay went boosted from INR 18,000,000 to INR 22,000,000 per year. Calculate the growth rate.

So, the answer is: Rs. 18,00,000 (the original salary)

Salary increase from Rs. 18,000 to Rs. 22,00,000

This means the pay increase is Rs 4,00,000 (Rs 22,00,000 minus Rs 18,00,000).

Pay increase % = (new salary / old salary) x 100

= (4,00,000/18,00,000) x 100 = 22.22%

• Another illustration:

The town’s population dropped from 18,560 to 15,787 due to an outbreak. When compared to what year did the population drop by that amount?

The answer is 18,560 at the time the population was first counted.

Population decrease = 15,787

Population decrease = 18,560 – 15,787 = -2,773

A decrease in population as a percentage is calculated as: (Decrease in population / Original population) x 100.

= (2773/18560) x 100 = 14.94% Previous post Laws of Divisibility Next post Best Universities in Singapore for All Students
