Grade Calculator: Weighted Average, GPA, and Academic Performance
Calculating your grade point average accurately is essential for students at every level. Whether you are in high school tracking your GPA for college applications, a university student monitoring your semester performance, or a parent helping your child understand their academic standing, a grade calculator simplifies the math and eliminates errors.
Our calculator supports both simple averages and weighted averages. A simple average treats all grades equally, while a weighted average accounts for courses that carry more credit hours or have higher importance. For example, a 4-credit course should have twice the impact on your GPA compared to a 2-credit course — this is exactly what weighted averaging does.
The tool also converts your weighted average to a GPA on a 4.0 scale, which is the standard used by most American universities. This conversion divides your weighted average by the maximum possible score and multiplies by 4. So if you score 85 out of 100 on a weighted basis, your GPA would be 3.40.
You can add as many grades as you need, label each one with the subject name for reference, and adjust the maximum score to match your school's grading system. Whether your scale goes to 100, 30 (common in Italy), or 20 (common in France), just set the max score and the GPA conversion adjusts automatically.
