How to use the Grade Calculator
Enter your subject names, marks (out of 100), and weights for each course. The calculator will instantly show your GPA (on a 4.0 scale) and average marks. You can add or remove subjects as needed.
Understanding GPA
Your Grade Point Average (GPA) is calculated by converting each subject's marks into a letter grade and GPA value, then averaging across all subjects (weighted by credit hours if applicable). Most universities use a 4.0 scale, where A+ is 4.0 and F is 0.0.
How weights work
Weights represent the importance or credit hours of each course. For example, a 3-credit course has a weight of 3, while a 1-credit course has a weight of 1. If all courses have equal weight, you can set each weight to 1 for a simple average.
Frequently asked questions
What is the difference between GPA and average marks?
Average marks is the simple numerical average of all your scores (e.g., 85%). GPA converts these marks into letter grades and then to a 4.0 scale. Most colleges focus on GPA rather than average marks.
Can I change the grade scale?
The calculator currently uses the standard 4.0 GPA scale used by most US colleges and universities. If your institution uses a different scale (like 10.0 or percentage-based), you may need to convert your grades manually.
How do weighted grades work?
In a weighted system, courses with higher credit hours or importance have more influence on your overall GPA. For example, a 4-credit course with an A will pull your GPA up more than a 1-credit course with an A.
What does each letter grade represent?
A+ (97-100) = 4.0 GPA, A (93-96) = 4.0, A- (90-92) = 3.7, B+ (87-89) = 3.3, B (83-86) = 3.0, B- (80-82) = 2.7, C+ (77-79) = 2.3, C (73-76) = 2.0, C- (70-72) = 1.7, D+ (67-69) = 1.3, D (63-66) = 1.0, D- (60-62) = 0.7, F (0-59) = 0.0.
