Percentage calculation is a very common skill that can come in handy in many situations. You will need this skill everywhere. You do not use it only in classrooms.

You will need it when calculating your performance as a percentage. You will need it when you need to determine the quantity to use in a scientific experiment.

It is easy to understand, and you can use it in multiple disciplines. You can use it to understand the student's performance in a certain subject or a year. Percentage is universal in every field; it does not have different versions, as seen in the grading system, where you had 4.0, 5.0, and 10.0 CGPA systems.

Percentage helps monitor a student's performance and can be improved by focusing on lower-performing areas. Calculating a percentage allows teachers and parents to track the student and guide him toward better results in the future.

As universities have different grading systems, percentage calculation gives a common ground to help them assess your competitiveness, and it makes things easier for you to land admission by laying a common ground. Our simple tool, a percentage calculator, makes things easier by giving simple calculations with less time consumption.

How is Percentage Calculated?

Calculating percentage is quite an easy job to do but doing things manually and quickly can lead to making small mistakes, thus giving wrong answers. To calculate percentage, a universal formula is used:

Percentage (%) = (Amount used / total amount) * 100

To represent percentage, the % sign is used universally. We will look for some specific formulas that can be used in academics. Multiplying your answer by 100 is important because the percentage ranges from 0 to 100.

Percentage of a single subject

To calculate the percentage for a single subject, we use the following formula:

Percentage (%) = (marks obtained / total marks) * 100

For example, if you have obtained 26 marks out of 35 in a subject, the percentage will be:

Percentage (%) = (26/35) * 100

Percentage (%) = 74.3 %

Percentage of multiple subjects

To calculate the percentage for multiple subjects, we use the following formula:

Percentage (%) = (sum of marks obtained in all subjects / total marks) * 100

For example, if you have obtained 31, 45, 33, and 47 marks in 4 subjects with total marks of 35, 60, 45, and 50 in each subject, respectively, the percentage will be:

Percentage (%) = (31+45+33+47) / (35+60+45+50) * 100

Percentage (%) = (156/190) * 100

Percentage (%) = 0.82 * 100

Percentage (%) = 82 %

Percentage calculation in Scientific Experiments

In scientific experiments, it is very crucial to use the proper quantity of substances to get the actual results. Let’s find out how to calculate the percentage of a specific substance in a mixture.

For example, you made a mixture of 20 grams by using 3 elements and you need to calculate the percentage of element “C” in the mixture. The grams you used for element “C” are 7 grams. You can calculate the percentage by the following formula:

Percentage (%) = (Grams used of element C / total grams of the mixture) * 100

Percentage (%) = (7 / 20) * 100

Percentage (%) = 35 %

How to use percentage calculator

We have designed this percentage calculator with comfort and ease of use in mind. There are not many steps to get the result. To calculate percentage, you need to follow simple steps. Let's see them through examples:

Calculating percentage of a Single Subject through our tool

It has never been this easy to calculate percentage using online platforms. You need to follow simple steps:

• Enter the marks obtained in the subject in the Obtained Marks field
• Enter the total marks in the Total Marks box
• Press Calculate

Let us take an example: you obtained 63 marks in history, and the total marks were 75, so as per the formula:

Percentage (%) = (marks obtained / total marks) * 100

Percentage (%) = (63 / 75) * 100

Percentage (%) = 84 %

This shows you got 84% on the history exam.

You do not have to indulge in all these calculations; you just enter the values, and our percentage converter will do the work for you. It saves you time and all the mental hassle. You can repeat the process for all the subjects that you want to find the results for.

Calculating percentage Multiple Subjects through our tool

Calculating the percentage for multiple subjects at once is a bit different, but not difficult. Our tool is designed to convert percentage smoothly and swiftly. Calculating percentage for multiple subjects will increase some more steps as explained below:

• Firstly, click on Add Subject and add as many subjects as you want to calculate
• Repeat the process for single subject method explained above for all subjects
• Enter the obtained marks for every subject and the total marks for that subject in the boxes
• Add as many as you need by clicking the Add Subject button
• Click Calculate at the end to get the results

Let’s assume you have received the following marks in different subjects

• 77 in English out of 90
• 55 in History out of 75
• 92 in Computer Science out of 100
• 87 in Mathematics out of 100

After adding all these marks in the boxes, simply click Calculate and our percentage converter will do the calculations. For the above example, following process is done at the back:

Sum of all obtained marks = 77+55+92+87 = 311

Sum of total marks = 90+75+100+100 = 365

Percentage (%) = (311/365) * 100

Percentage (%) = 85 %

The student obtained 85% with the above marks in 4 subjects.
