GPA Calculator
Calculate semester or cumulative Grade Point Average (GPA) on the standard 4.0 scale weighted by course credit hours.
High School & College GPA Calculator
Calculate your weighted and unweighted cumulative GPA on the standard 4.0 / 5.0 grading scale with Honors and AP/IB weighting.
Tip: Standard high school and college courses are 3 or 4 credits. Honors courses earn +0.5 GPA bonus; AP and IB courses earn +1.0 bonus.
Weighted GPA (5.0 scale) | Unweighted: 3.55 (4.0 scale)
- 1.Sum total credits attempted: 3cr + 4cr + 4cr + 3cr + 3cr = 17 credits
- 2.Unweighted grade points (credits × 4.0 points): (3 × 4.0) + (4 × 3.3) + (4 × 3.0) + (3 × 3.7) + (3 × 4.0) = 60.30 pts
- 3.Unweighted GPA: 60.30 points ÷ 17 credits = 3.55
- 4.Weighted grade points (with Honors +0.5 / AP +1.0): (3 × 5.0) + (4 × 3.8) + (4 × 3.0) + (3 × 3.7) + (3 × 4.0) = 65.30 pts
- 5.Weighted GPA: 65.30 points ÷ 17 credits = 3.84 (on 5.0 weighted scale)
- 6.Standard US scale: A+/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+=1.3, D=1.0, D-=0.7, F=0.0
Mathematical Formula & Calculation Method
Formula Components:
- Standard 4.0 Scale: 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+=1.3, D=1.0, F=0.0
- Course Grade Points = Course Credit Hours × Grade Numeric Value
- Total Grade Points = Sum of all (Course Credits × Grade Numeric Value)
- Cumulative GPA = Total Grade Points ÷ Total Attempted Credit Hours
How It Works
Add your courses with class title, credit hours (e.g. 3 or 4 credits), and letter grade.
Click "+ Add Course" to add additional classes as needed.
The calculator computes total credit hours, total quality points, and your weighted GPA.
Practical Calculation Examples
Semester with 4 Classes (14 Total Credits)
Calculus (4 cr, A), Physics (4 cr, B), English (3 cr, A), History (3 cr, B+).
Important Assumptions & Estimator Guidance
- Uses the standard North American 4.0 unweighted grading scale.
- Assumes all listed courses are credit-bearing letter grades (Pass/Fail and Audited courses do not affect GPA).
- Honors or AP weighted 5.0 scales are not used unless manually configured.
Common Pitfalls & Mistakes to Avoid
Averaging letter grade values without weighting by credit hours
A 4-credit laboratory science course has double the impact on your GPA compared to a 2-credit elective.
