What Is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. It represents a part of a whole and is widely used in academics, finance, and everyday calculations. For instance, scoring 75% means you've achieved 75 out of 100.
Percentages help in comparing marks across different exams and subjects, regardless of varying total marks.
Why Is Calculating Marks Percentage Important?
Understanding your marks percentage can help:
Assess Academic Performance: Determine how well you’ve done in a subject or overall.
Eligibility Criteria: Many schools, colleges, and scholarships set percentage-based criteria for admission or funding.
Goal Setting: Knowing your percentage helps you identify areas for improvement.
How to Calculate Marks Percentage
Let’s break the process into simple, actionable steps.
Step 1: Understand the Formula
The formula to calculate percentage is:
Percentage
=
(
Obtained Marks
Total Marks
)
×
100
Percentage=(
Total Marks
Obtained Marks
)×100
Step 2: Gather the Required Data
Obtained Marks: The marks you scored in the subject or exam.
Total Marks: The maximum marks for the subject or exam.
Step 3: Perform the Calculation
Divide your obtained marks by the total marks, then multiply by 100.
Example 1: Single Subject Percentage
Imagine you scored 45 marks out of 50 in a Math test.
Divide Obtained Marks by Total Marks:
45
50
=
0.9
50
45
=0.9
Multiply by 100:
0.9
×
100
=
90
%
0.9×100=90%
So, your percentage in Math is 90%.
Example 2: Overall Percentage for Multiple Subjects
Let’s calculate the percentage for five subjects:
Subject Marks Obtained Total Marks
Math 80 100
Science 75 100
English 85 100
History 90 100
Geography 70 100
Calculate Total Marks Obtained:
80
+
75
+
85
+
90
+
70
=
400
80+75+85+90+70=400
Calculate Total Maximum Marks:
100
+
100
+
100
+
100
+
100
=
500
100+100+100+100+100=500
Apply the Formula:
Percentage
=
(
400
500
)
×
100
=
80
%
Percentage=(
500
400
)×100=80%
Your overall percentage is 80%.
Common Mistakes to Avoid
Ignoring Decimal Points: Always round off decimals correctly.
Wrong Totals: Double-check your obtained and total marks before calculating.
Weightage Errors: Some exams assign different weights to subjects, so ensure you factor those in.
Tips for Accurate Percentage Calculation
Use a calculator to minimize errors.
Double-check your data, especially when dealing with large numbers.
Practice with examples to build confidence.
Advanced Scenarios: Weighted Percentage Calculations
In some cases, subjects may carry different weightages. Here’s how to handle that:
Weighted Example
Subject Marks Obtained Total Marks Weightage
Math 80 100 40%
Science 90 100 30%
English 70 100 30%
Multiply each subject’s percentage by its weightage:
Math:
80
100
×
40
=
32
100
80
×40=32
Science:
90
100
×
30
=
27
100
90
×30=27
English:
70
100
×
30
=
21
100
70
×30=21
Add the results:
32
+
27
+
21
=
80
%
32+27+21=80%
Your weighted percentage is 80%.
