What Is a Marks to Percentage Calculator?

A Marks to Percentage Calculator is an essential academic tool that converts raw marks obtained in exams, assignments, or tests into percentage format. This calculator is particularly useful for students who need to understand their performance in standardized percentage terms for academic records, college applications, or competitive exam preparations.

The calculator uses the simple formula: Percentage = (Obtained Marks ÷ Total Marks) × 100, providing instant and accurate conversions that help students track their academic progress and meet institutional requirements.

Understanding Different Calculation Methods

There are different ways to calculate percentages depending on whether you're dealing with single subjects or multiple subjects. Understanding these methods helps ensure accurate calculations for different academic scenarios.

Single Subject Percentage

Percentage = (Obtained Marks ÷ Total Marks) × 100

Used for individual subject calculations, assignments, or single exam evaluations. Example: 85 marks out of 100 = (85 ÷ 100) × 100 = 85%

Overall Percentage (Multiple Subjects)

Overall % = (Total Obtained Marks ÷ Total Maximum Marks) × 100

Used for calculating aggregate percentage across all subjects. Example: 340 out of 400 total marks = (340 ÷ 400) × 100 = 85%

Average Percentage

Average % = Sum of Individual Percentages ÷ Number of Subjects

Sometimes used when subjects have equal weightage, but overall percentage is more accurate for most academic purposes.
