This advanced grade calculator helps students and teachers instantly calculate percentage grades, letter grades, GPA (4.0 scale), and weighted averages. Whether you're calculating exam results, assignment scores, semester performance, or final grades, this tool provides fast and accurate results.

What This Grade Calculator Does

This tool converts raw marks into percentage, assigns a letter grade based on standard grading scales, calculates GPA values, and optionally computes weighted grades for assignments and exams.

How the Grade Calculation Works

The basic percentage formula is:

(Obtained Marks ÷ Total Marks) × 100

Weighted grades are calculated using:

(Assignment Score × Assignment Weight) + (Exam Score × Exam Weight)

  • A = 85–89%

  • D = 50–54%
  • F = Below 50%

Practical Use Cases
