GPA Calculator
Calculate semester and cumulative GPA on a 4.0 scale. Add courses with credits and letter grades to get grade points, weighted GPA, and breakdown charts.
About This Calculator
Our GPA Calculator helps students at high schools, colleges, and universities calculate their Grade Point Average quickly and accurately. Whether you need your semester GPA for one term or want to understand how individual course grades affect your overall academic standing, this tool supports the standard 4.0 scale with plus and minus letter grades.
GPA is calculated using a weighted average formula: multiply each course's grade point equivalent (A=4.0, A-=3.7, B+=3.3, B=3.0, etc.) by its credit hours, sum all results, then divide by the total number of credit hours attempted. For example, an A (4.0) in a 3-credit course contributes 12 grade points, while a B (3.0) in a 4-credit course contributes 12 grade points. This means higher-credit courses have a proportionally larger impact on your final GPA.
Our calculator provides a course-by-course breakdown table showing each grade's quality points contribution, plus interactive charts that visualize grade point distribution across your courses. The calculator handles up to 20 courses per calculation session, supports shareable URL links so you can save or send your course list, and includes both bar chart (grade points per course) and doughnut chart (grade distribution) views.
Regional Notes
United States: Most US high schools and colleges use the 4.0 unweighted scale shown here. Some high schools also compute weighted GPAs adding 0.5 for honors and 1.0 for AP/IB courses. US colleges often recalculate GPA using only core academic courses.
India: Indian universities typically use percentage-based grading or a 10-point CGPA scale. To convert CGPA to percentage, multiply by 9.5 (standard formula used by many Indian institutions like CBSE). This calculator's 4.0 scale serves as a reference for US-style grading used by international schools and study-abroad programs.
United Kingdom: UK universities use degree classifications (First Class Honours, Upper Second/Lower Second, Third Class) rather than GPA. However, some UK institutions now provide GPA equivalents for international students, typically using a 4.0 or 4.3 scale for exchange programs and US graduate school applications.
Frequently Asked Questions
How is GPA calculated?
GPA is calculated by dividing total grade points earned by total credits attempted. Each letter grade is assigned quality points (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). Multiply each course's grade points by its credits, sum all courses, then divide by total credits.
What is the difference between weighted and unweighted GPA?
Unweighted GPA uses a standard 4.0 scale where an A is always 4.0 regardless of course difficulty. Weighted GPA gives extra points for honors, AP, IB, or college-level courses (typically +0.5 for honors, +1.0 for AP/IB). Most US high schools use weighted GPAs, while colleges often recalculate on an unweighted scale for admissions.
What is considered a good GPA?
A GPA of 3.0 (B average) is generally considered good. A 3.5 or above is excellent, and a 4.0 is perfect. For competitive US college admissions, a 3.7+ unweighted or 4.0+ weighted is often expected. In the UK, degree classifications (First, 2:1, 2:2) are used instead of GPA. Indian universities typically use percentage-based grading.
How do I calculate cumulative GPA across multiple semesters?
Cumulative GPA is calculated by taking the total grade points earned across all semesters and dividing by the total credits attempted across all semesters. Multiply each semester's GPA by its credits, sum them, then divide by the sum of all credits. This weighted average accounts for varying course loads each semester.
Do different countries use different GPA scales?
Yes, GPA systems vary by country. The US uses a 4.0 scale with letter grades. India uses percentage-based grading (60-100% = First Division, 50-60% = Second Division). The UK uses degree classifications (First Class Honours = 70%+, Upper Second = 60-69%, Lower Second = 50-59%). Canada uses both percentage and 4.0 GPA. Australia uses a 7.0 GPA scale.
Can I calculate my GPA if I have pass/fail courses?
Most institutions exclude pass/fail courses from GPA calculations. Only the credits attempted and grade points from graded courses (A through F) affect your GPA. Pass/fail courses count toward enrollment status and graduation requirements but do not impact your grade point average.
What is the difference between semester GPA and cumulative GPA?
Semester GPA is calculated using only courses taken in a single term. Cumulative GPA covers all courses taken across every semester or term. Cumulative GPA is the one that appears on your transcript and is used by employers and graduate schools for overall academic assessment.
How do I improve my GPA?
To improve your GPA, focus on retaking low-grade courses if allowed, prioritize higher-credit courses where grade improvements have more impact, develop consistent study habits, use office hours and tutoring resources, and consider a manageable course load. Each A raises your GPA more effectively when earned in higher-credit courses.
