The Formula for Calculating Marks Percentage

The basic formula to calculate the percentage of your marks is straightforward:

Percentage = (Marks Obtained / Total Possible Marks) × 100

This formula works whether you're calculating the percentage for a single test or for multiple subjects combined. Let's break down how to apply it.

Calculating Percentage for a Single Subject

Let's say you scored 75 marks in a subject where the total possible marks were 100. Applying the formula:

Percentage = (75 / 100) × 100 = 75%

Therefore, you scored 75% in that subject. It's that simple! But what if you need to calculate the overall percentage across multiple subjects?

Calculating Overall Percentage for Multiple Subjects

When calculating the overall percentage from multiple subjects, you need to consider the total marks obtained in all subjects and the total possible marks for all subjects.

  1. Sum up the marks obtained in each subject.
  2. Sum up the total possible marks for each subject.
  3. Apply the percentage formula: (Total Marks Obtained / Total Possible Marks) × 100

Example: Suppose you scored the following marks in four subjects:

  • Maths: 80/100
  • Science: 70/100
  • English: 90/100
  • History: 85/100

Total Marks Obtained = 80 + 70 + 90 + 85 = 325

Total Possible Marks = 100 + 100 + 100 + 100 = 400

Overall Percentage = (325 / 400) × 100 = 81.25%

So, your overall percentage across all four subjects is 81.25%.

Common Mistakes to Avoid

While the formula is straightforward, it's easy to make mistakes. Here are some common errors to avoid:

  • Incorrect Input: Always double-check the marks obtained and total possible marks.
  • Math Errors: Review your addition and division to ensure accuracy.
  • Using Incorrect Totals: Be sure you're using the combined totals for multiple subjects, not individual subject totals.
