Grade distribution (credits)
The weighted average uses the selected grade table. Other scales are simple proportional references; official institutional conversion, repeat-course and pass/fail rules take priority.

Reading a credit-weighted GPA across scales
GPA is weighted by course credits, not a simple count of courses.
Scale definitions differ, so proportional values are only a quick comparison.
Credits determine each course’s weight
GPA is weighted by credits, not by the number of courses. A three-credit course affects the average three times as much as a one-credit course with the same grade.
Course names are notes; credits and grades drive the calculation.
- Quality points = credits × grade points
- GPA = quality points ÷ included credits
- More credits mean more weight
Start with the 4.5 grade table
The default table runs from A+ 4.5 and A 4.0 to F 0 in half-point steps. Institutions using A-, numerical marks or another table require a different mapping.
Match each screen grade to the official transcript notation before calculating.
- A+ 4.5 · A 4.0
- B+ 3.5 · B 3.0
- F 0 · P/NP excluded
Keep pass/fail outside GPA
P and NP are treated as pass/fail outcomes without grade points, so they leave both the numerator and included-credit denominator.
An institution may still count a pass toward earned credits; check that rule separately.
- P/NP excluded from GPA
- Earned-credit treatment can differ
- F remains a zero-point grade
Check the definition of a 4.3 scale
The 4.3 reference multiplies the 4.5 GPA by 4.3/4.5. A real 4.3 system normally assigns points to each letter grade instead.
A transcript with many A+ grades can therefore differ materially from the proportional result.
- Useful for a quick comparison
- Recalculate course by course with an official table
- Receiving rules take priority
A 4.0 scale may treat A+ differently
A 4.0 system may cap A+ at 4.0 or use plus/minus values such as 3.7 for A-. Proportional scaling does not reproduce those grade-level choices.
Use only the conversion requested by the school, employer or credential evaluator.
- Check how A+ is treated
- Check plus/minus points
- Follow the evaluator’s table
The 100-point value is proportional
The 100-point reference is GPA/4.5×100. It is not an average of original exam marks, a percentile rank or an institution’s published percentage formula.
If the transcript provides an official percentage, use that value.
- Proportion is not raw-mark average
- Percentage is not percentile
- Official transcript values prevail
Follow the transcript policy for repeats
Entering both the old and new attempt of a repeated course can double-weight it when the institution replaces the earlier grade. Policies may replace, average or retain both attempts.
Keep only the rows that the official cumulative GPA actually uses.
- Check replacement policy
- Look for duplicate attempts
- Reconcile with the final transcript
Separate major and cumulative GPA
A major GPA uses only courses assigned to the major; a cumulative GPA uses every included course. They answer different admissions questions.
Use the institution’s classification for electives, double majors and transferred courses.
- Filter major courses
- Calculate cumulative GPA separately
- Match the application field
Verify the weighted average with an example
For 3 credits of A+, 3 of B+, 2 of A and 3 of B, the quality-point sum is 41. Dividing by 11 included credits gives about 3.73.
Checking each product and the credit total is a practical way to find input errors.
- Quality points: 41
- Included credits: 11
- 41 ÷ 11 ≈ 3.73
Use institutional rules for submission
For official submission, the transcript, institutional policy and credential evaluator instructions outrank this calculator. ECTS recognition and foreign-qualification decisions use more than a ratio of maximum scores.
Use the tool to check arithmetic and understand scale differences, not to predict recognition.
- Use the official transcript
- Read receiving instructions
- No guarantee of credential recognition
GPA calculation and scale comparison FAQ
QHow is GPA calculated?
It is the sum of credits times grade points divided by included credits.
QAre the other scales official conversions?
No. They are proportional references from the 4.5 result.
QWhat points do A+ and A receive?
The default table assigns 4.5 to A+ and 4.0 to A.
QHow are P and NP handled?
They are excluded from GPA and included credits.
QHow should repeated courses be entered?
Keep only the attempts used by the official transcript policy.
QCan I calculate a major GPA?
Yes. Keep only courses that belong to the major.
QWhy do credits matter?
A three-credit course has three times the weight of a one-credit course.
QWhich value should I submit?
Use the transcript and scale requested by the receiving institution.
