GPA Calculator
Calculate your Grade Point Average (GPA) from course grades and credit hours.
Calculator
Formula
Grade Points are the numeric value assigned to a letter grade (e.g., A = 4.0, B = 3.0). Credit Hours are the weight of each course. The sum of all (Grade Points × Credit Hours) is divided by total Credit Hours.
Source: Standard 4.0 GPA scale used by most US colleges and universities.
How it works
Each course contributes to your GPA in proportion to its credit hours. A 4-credit course has twice the impact on your GPA as a 2-credit course. To find the weighted average, multiply each course's grade points by its credit hours, sum all those products (called quality points), then divide by the total number of credit hours attempted.
On the standard 4.0 scale, letter grades map as follows: 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. Enter the numeric equivalent for each course to get your accurate GPA.
Worked example
Suppose you take five courses in a semester:
- Calculus (4 credits): A = 4.0 → 4.0 × 4 = 16.0 quality points
- History (3 credits): B+ = 3.3 → 3.3 × 3 = 9.9 quality points
- English (3 credits): A− = 3.7 → 3.7 × 3 = 11.1 quality points
- Physics (4 credits): B = 3.0 → 3.0 × 4 = 12.0 quality points
- Art (2 credits): C+ = 2.3 → 2.3 × 2 = 4.6 quality points
Total quality points: 16.0 + 9.9 + 11.1 + 12.0 + 4.6 = 53.6
Total credits: 4 + 3 + 3 + 4 + 2 = 16
GPA = 53.6 ÷ 16 = 3.35
Limitations & notes
This calculator supports up to 5 courses per calculation. For more courses, calculate in batches or use a cumulative GPA approach. Note that some institutions use a different grading scale (e.g., 4.3 or 5.0 scales), and plus/minus grades may be handled differently depending on school policy. Pass/Fail and Incomplete courses are typically excluded from GPA calculations.
Frequently asked questions
What is a good GPA?
A GPA of 3.0 (B average) is generally considered good, while 3.5 and above is considered excellent at most institutions. Requirements vary by program and school.
How do I convert letter grades to grade points?
On the standard 4.0 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 = 1.0, F = 0.0. Check your institution's specific scale as it may vary.
What is the difference between semester GPA and cumulative GPA?
Semester GPA reflects only the courses taken in a single term, while cumulative GPA averages all courses taken throughout your entire academic career. Use this calculator for either by entering the relevant courses.
Do pass/fail courses affect my GPA?
At most institutions, courses graded Pass/Fail do not count toward your GPA calculation. Only letter-graded courses with quality points are included.
Can I calculate my cumulative GPA with this tool?
Yes — treat your previous cumulative GPA as one 'course' by entering your prior GPA and total credits earned, then add your new courses. The weighted average will give your updated cumulative GPA.
