The Semester GPA Calculator estimates grade point average using each course group’s credits and grade points. It supports up to four grade groups, allowing repeated grade values to be combined by total credits.
The result is a credit-weighted GPA rather than a simple average of grades. Use it to test possible semester outcomes, but enter grade points that match your school’s grading scale because scales and treatment of repeated courses can differ.
1. Enter course credits
Enter the credit value for each course or grade group.
2. Enter matching grade points
Use your institution’s numeric grade-point value for that course.
3. Leave unused rows at zero credits
Rows with zero credits do not affect GPA.
4. Review total quality points
Quality points equal credits multiplied by grade points.
5. Check semester GPA
Use the weighted result for planning, not as an official transcript value.
Quality points for a course = Course credits × Grade points Semester GPA = Sum of quality points ÷ Sum of attempted credits
The calculation assumes every entered credit is GPA-bearing and uses the supplied grade-point scale.
The main result is the weighted average grade points earned per attempted credit.
Results are planning estimates based on the values entered and may differ from school-specific grading or attendance policies.
Given: 3 credits at 4.0, 4 credits at 3.3, 3 credits at 3.7, and 3 credits at 2.7.
Calculation: Quality points = 12 + 13.2 + 11.1 + 8.1 = 44.4. Credits = 13. GPA = 44.4 ÷ 13 = 3.415.
Result: The estimated semester GPA is 3.42.
Include them only if your institution assigns grade points and counts them in GPA.
Use the exact grade-point scale applied by your school, such as 4.0 or 4.3.
Policies differ. Enter the credits and grade points that your institution actually includes in the semester GPA.
Yes. Add their credits together and enter the shared grade-point value once.
GPA is credit-weighted, so courses carrying more credits contribute more quality points.
