Why GPA is not always the average of your course grades
Credit hours determine the weight of each course. A higher-credit course has more influence even when only two courses are involved.
GPA calculator →Work through unequal credits
A course with 4.0 grade points and three credits contributes twelve quality points. A course with 2.0 grade points and one credit contributes two. The total is fourteen quality points over four credits, giving a GPA of 3.5. Simply averaging four and two gives 3.0 because it ignores the unequal credit weights.
Keep the two input lists aligned
Enter grade points as 4,2 and matching credits as 3,1. Reversing the credit list to 1,3 changes the result to 2.5 by assigning the larger weight to the lower grade. That is an input-pairing error rather than a failure of the weighted-average formula. Check each pair against the transcript before calculating a large list.
Use the institution’s inclusion rules
This site accepts numeric grade points from zero to four and does not automatically translate letter grades under every local system. Repeated courses, pass/fail results, transfer credit and degree-specific GPA scopes can follow different institutional policies. Determine which courses and credits belong in the calculation first. The average tool explains the unweighted case, while the final-grade tool answers a separate question about a future assessment.
