In all these years, if there is one calculation that stays with us like a shadow, it is the percentage. “How to calculate the percentage of marks” becomes one of the most common questions.
Calculating the overall percentage, checking improvement, and overall ranks— all of this and more require percentage calculations. It has become such a natural part of your academic life that if you sit and think this calculation holds a huge responsibility. Through this, you can measure your growth, achievements, and much more.
However, it may not be as easy as it sounds to calculate the percentage. Numbers and calculations can be a lot, and that is why through this blog we intend to simplify the process for you. In this blog, you would know “how to calculate percentage of marks”, definition and importance with various examples. We would also give you some other insights and tips related to calculating the percentages of marks.
A percentage is calculated out of 100. It is a number that represents the fractions of 100. The symbol for identifying a percentage is ‘%’. So if you want to calculate percentage of marks, it would be out of 100; for example, if you score 70 out of 100 marks, then your percentage would be 70%. It is this simple.
Planning to apply for an undergraduate or switch schools, or just self-analysing all of it, requires a calculation of the percentage. We cannot stress enough the importance of percentages. This has standardised how we measure the performance throughout the nation.
First, we would take you through the formulae, which are pretty easy to understand. Next, we shall discuss and elaborate on it with the help of examples. The formula to calculate the percentage is:
Percentage = (Actual Value / Total Value) × 100
Example 1: You scored 70 out of 80 marks on your English exam.
Percentage = (70 / 80) × 100 = 87.5%
Example 2: You scored 45 out of 50 marks on your Maths exam.
Percentage = (45 / 50) × 100 = 90%
Do you see how straightforward it is to calculate the percentage of marks? Now, what if, rather than a single subject, you have to calculate the score for multiple subjects? Let’s go through some examples for multiple subjects:
Example 1: Your final exams are done, and you have scored 90 in English, 95 in Hindi, 85 in Science, and 96 in Social Studies. Calculate the percentage.
Actual Value = 366
Total Value = 400
Percentage = (366 / 400) × 100 = 91.5%
Example 2: Your exam scores have come out, and they are as follows: 85 in Maths, 90 in Science, and 70 in History.
Actual Value = 245
Total Value = 300
Percentage = (245 / 300) × 100 = 81.67%
Example 3: Your exam scores have come out, and they are as follows: 92 in Maths, 85 in Science, and 78 in History.
Actual Value = 255
Total Value = 300
Percentage = (255 / 300) × 100 = 85%
Here is a list of tips that you must follow before calculating the percentage:
| Marks Scored | Percentage Value |
|---|---|
| 10 | 10% |
| 20 | 20% |
| 30 | 30% |
| 40 | 40% |
| 50 | 50% |
| 60 | 60% |
| 70 | 70% |
| 80 | 80% |
| 90 | 90% |
| 100 | 100% |
To calculate the class average percentage, there are a few steps:
Imagine if the class includes 20 students. You need to add the total marks for the whole class.
Divide it by the total maximum marks.
Once you have the value, multiply it by 100. You would get the desired result.
Example 1: A total of 20 students in the class scored 800 out of 1000.
Average Percentage of the Class = (800 / 1000) × 100 = 80%
This tool has simplified the process of calculating the percentage of marks by manifold. Now if you want to get results, you need not invest more than a few seconds. Just fill out the information and get the desired result. Follow these steps to calculate the percentage:
Like how you put the category of the item you want on the search bar, similarly, you would enter the actual and total value. Let us understand this with an example:
If the actual value after adding the marks is 250 out of 300, then the percentage will be:
Percentage = (250 / 300) × 100 = 83.33%
As you insert the value and press solve, the tool would process the values in the formula.
As soon as the process is done, you would get the percentage.
As we sign off, we would like to again highlight the importance of percentages. It is not just a number but an indicator to assess performance and hard work.
