Academic calculator for planning
GPA Calculator
Estimate your semester GPA and cumulative GPA from courses, credits, and grades. The calculator uses a common 4.0 grade scale, but grading policies vary by school.

GPA summary
Formula used
GPA = total quality points divided by GPA credits attempted.
This GPA calculator uses the editable scale below, so you can adjust grade points if your school handles plus/minus grades differently.
A 4.0
A- 3.7
B+ 3.3
B 3.0
B- 2.7
C+ 2.3
C 2.0
C- 1.7
D 1.0
F 0.0
How to use the GPA calculator
- Enter each current course with the number of GPA credits it carries.
- Select the letter grade you expect or earned for each course.
- Use the default grade points or edit them to match your school scale.
- Add current cumulative GPA and completed GPA credits to estimate a new cumulative result.
- Review repeated-course, pass/fail, withdrawal, and transfer-credit rules before using the number for planning.
What the results mean
Semester GPA uses only the course rows in the table. Cumulative GPA combines your prior transcript total with the current semester estimate. If prior information is blank, the cumulative result matches the semester result.
Quality points are the bridge between grades and credits. A 3-credit course with a B grade on the default 4.0 scale contributes 9.00 quality points. More credits make a course influence your grade point average more heavily.
Review checklist
- Confirm whether your school uses plus/minus grades.
- Check if repeated courses replace or average previous attempts.
- Exclude pass/fail, audit, incomplete, or withdrawal courses unless they carry GPA points.
- Use GPA credits from your transcript, not total credits earned, when those differ.
- Compare the estimate with advising or registrar guidance before making academic decisions.
Planning notes
When to include cumulative data
Use only the course rows when you want a clean semester GPA. Add current cumulative GPA and completed GPA credits when you want to test how the next term may change your transcript average. The prior GPA field should come from your transcript or student portal, and the completed credits field should count only credits that already carry GPA points.
Weighted high school classes, graduate program scales, repeated attempts, and transfer work can all change how a school calculates grade point average. If your transcript lists total quality points, you can compare those totals with the calculator output to see whether the same grade scale is being used.
Examples
Common GPA calculator scenarios
Strong semester
Four 3-credit classes with A, A-, B+, and B grades produce 41.70 quality points over 12 credits, or a 3.48 semester GPA.
Cumulative planning
A student with a 3.20 current GPA and 60 completed credits can add 15 new credits to see how a higher or lower term changes the projected cumulative GPA.
Credit-heavy course
A 5-credit lab course has more effect than a 1-credit seminar. Enter credits carefully so the calculator weighs each course correctly.
Different GPA scale
If your school counts A- as 3.67 instead of 3.70, edit the grade points field after selecting the grade. The row quality points update from that value.
FAQ
GPA calculator questions
How is GPA calculated?
GPA is calculated by multiplying each course grade point value by its credits, adding those quality points together, and dividing by total GPA credits.
What is the difference between GPA and CGPA?
GPA can describe one term, while CGPA or cumulative GPA usually combines completed terms into one transcript average. This page can estimate both.
Can this GPA calculator work for college and high school?
It works for common credit-based 4.0 planning. High schools with weighted honors or AP scales may need adjusted grade points.
Should pass/fail courses be included?
Usually only courses with grade points should be included. Pass/fail, audit, incomplete, or withdrawal marks often affect credits differently by school.
Why does my transcript show a different number?
Transcript systems may apply repeated-course rules, transfer policies, departmental exclusions, rounding, or grade forgiveness. Use this as an estimate to review.
Are calculations saved or uploaded?
No account is used. The calculation runs in your browser and the page does not require uploading a transcript or document.
Limitations and privacy notes
This independent educational tool helps calculate GPA estimates for planning. It does not replace your school record, adviser guidance, registrar rules, scholarship requirements, or program-specific academic standing policy. Always compare the result with the source your school tells students to use.
The calculator is designed for visible, manual entry. It does not read transcript files, connect to student accounts, store rows on a server, or decide whether a course should be excluded from GPA credits. If a course has unusual grading, edit the grade points or leave that course out until you confirm the rule.
