Calculating the percentage of marks (Easy and Simple formula!)

Here's how to calculate the percentage of marks scored in different subjects or to evaluate academic performance / academic excellence.

Percentage of marks = (Total marks earned/marks available) * 100

Example: Calculating exam percentage

Let's say you scored 57 on an English test out of 112 marks. The percentage of marks is calculated using the following formula:

  • Divide scored marks earned by total marks: 57 / 112 = 0.51
  • Multiply by 100 to get percentage: 0.51 x 100 = 51%

So, you scored 51% on the test!

Difference between percentage and percentile

  • A percentage is a ratio of two quantities measured out of 100. The term percent is derived from the Latin word "per centum," which means “by the hundred.”
  • A percentile is a value in a data set that indicates the relative standing of a particular data point.

For example, if 60% of students in a class are female, then there are 60 females out of 100 students. In other words, the quantity of females is 60/100 of the total number of students in the class.

  • Percentile is a statistic that measures the value below a certain percentage of specific values. The percentile rank is a standard metric to report results from competitive exams such as college entrance tests.

For instance, if the 95th percentile score on a test is 80%, 95% of test takers score below 80%.

How to calculate percentage increase?

Percentage increase is the ratio of increased value and the initial value in the form of a percentage. 

Calculating the percentage increase can be done in a few simple steps.

  1. You're given two numbers, an initial value and a final value, you should find the difference between the two figures. 
  2. You can calculate this by subtracting the lower number from the higher one.

For example, a person’s salary has increased from $50,000 to $60,000.

Here,

The initial value = $50,000

The final value = $60,000

Percentage increase = (Final value - Initial value)/Initial value x 100

To find the difference, we take the highest figure out of these two numbers and subtract the lowest number.

Difference = $60,000 - $50,000 = $10,000

You then use this figure and divide it by the original number.

$10,000/$50,000 = 0.2

Then, multiply the result by 100 to get the profit percentage.

Profit percentage = 0.2 x 100 = 20%

So the percentage increase, in this case, is 20%.

The steps to obtain a percentage increase could be summarised as follows:

Step 1: Find the difference (Highest number - lowest number)

Step 2: Divide the difference by the original number (Difference/Original number)

Step 3: Multiply the result by 100 (Result x 100).

Here’s another example,

The original value = 800

The new value = 1000

Percentage increase = (New value - Original value)/Original value x 100

Percentage increase = ((1000 - 800)/1000) x 100 = (200/1000) x 100

= 0.2 x 100 = 20%

How to calculate percentage decrease?

Percentage decrease depicts the loss of a value in terms of a percent. Here are the steps to calculate the percentage decrease.

Find the difference between the two numbers, divide the difference by the initial value, and multiply the result by 100.

Percentage decrease = (Initial value - Final value)/Initial value x 100

For example, imagine someone's salary dropped from $30,000 to $25,000.

Here,

The initial value = $30,000

The final value = $25,000

Difference = $30,000 - $25,000 = 5,000

Then, divide the difference by the original number.

$5,000 / $30,000 = 0.17

Finally, we multiply the result by 100 to get the percentage decrease.

Percentage decrease = 0.17 x 100 = 17%

So the percentage decrease is 17%.

The percentage decrease formula would follow this process:

Percentage decrease = ((30000 - 25000)/30000) x 100 = (5000/30000) x 100 = 0.17 x 100 = 17%

The steps to obtain a percentage decrease are as follows:

Step 1: Find the difference (Highest number - lowest number)

Step 2: Divide the difference by the original number (Difference/Original number)

Step 3: Multiply the result by 100.

How to calculate the percentage of a number?

To calculate the percentage of any number, you should divide the number by 100 and then multiply it by the desired percentage.

Percentage of a number = (Original number/100) x Percentage

For example, to get 50% of 60, we would divide 60 by 100 to get 0.6 and then multiply that by 50 to get 30. The final answer would be 30. Here’s how.

Percentage of a number = (60/100) x 50 = 0.6 x 50 = 30

How to convert a fraction to a percentage?

There are different methods to convert fraction form to percentages. Before we proceed with the calculations, let’s learn the difference between a percentage and a fraction form. Understanding these concepts will help you solve problems more effectively.

What is the difference between a percentage and a fraction form?

Percentage Fraction
A percentage is a number that represents a fraction of 100.A fraction, on the other hand, is a number that represents a part of a whole.
For example, 50% of something is half of it.For example, 1/2 of something is one out of two parts.
When you're working with percentages, remember that 100% represents the entire amount.When you're working with fractions, it's important to remember that the denominator represents the whole amount.

How to convert a fraction into a percentage?

  1. The first method is to multiply the fraction by 100.

For example, if you want to convert the fraction ¾ to a percentage, multiply the fraction by 100, and you get 75%.

  1. There is another method where you can divide the fraction's numerator (top number) by the denominator (bottom number) and then multiply that answer by 100. 

For example, using the same fraction ¾, divide 3 by 4 to get 0.75 and multiply the number by 100 to also get 75%.

How to calculate percentage change

Many students often wonder how to find percentage change, as it helps them analyse fluctuations in their academic performance.

You can use a simple formula:

Percentage Change = ((New value- Old value)/ Old value)*100

Example:

Suppose a student scored 75% in the first term, and then their score increased to 88%. To calculate the change in percentage:

1. Identify the old value (75) and the new value (88).

2. Apply the formula:

Percentage Change = ((88- 75)/ 75)100 = (13/75)*100 =17.333

Thus, the percentage change in the score is approximately 17.33%.

Understanding Percentage Error

Percentage error measures how close an estimated value is to the actual value, calculated using the formula:

Percentage Change = ((Estimated value- Actual value)/ Actual value)*100

Example:

A 10th-grade student estimated they would score about 95% on their final exam, but the actual result was 87%. To find the percentage error:

  1. Identify the estimated value (95) and the actual value (87).
  2. Apply the formula:

Percentage error = ((95-87)/87)100= (8/87)*100= 9.20%

Therefore, the percentage error is approximately 9.20%.
