What Is a Grade Calculator?
A grade calculator is a tool that converts raw marks into letter grades and grade points, then computes a weighted GPA based on each subject's credit hours. It removes the guesswork from manual calculations and lets you focus on improving your performance.
Unlike simple average calculators, this tool weights each subject by its credit value — so a 4-credit course contributes more to your GPA than a 1-credit lab, exactly as your institution does.
GPA vs Percentage — What's the Difference?
Your GPA (Grade Point Average) is a weighted number on a fixed scale (4.0, 5.0, or 10.0) that standardises grades across subjects. Your percentage is the simple arithmetic mean of all your marks out of 100. Both are shown side-by-side in the result panel so you always have the complete picture.
