GPA Calculator

Tracking your GPA is essential for scholarships, graduate school applications, and academic standing. This GPA calculator lets you compute your semester GPA, cumulative GPA, and even run "what-if" scenarios to see what grades you'll need to hit your target.

What Does This Calculator Do?

Enter your courses, grades (letter or percentage), and credit hours to calculate your weighted GPA. Add previous semester data to find your cumulative GPA.

How to Use This Calculator

1. Enter each course name (optional).
2. Enter the grade (letter grade: A, B+, C, etc.).
3. Enter the credit hours for each course.
4. Click Add Course and repeat for each class.
5. Click Calculate GPA to see your semester GPA.
6. To find cumulative GPA, enter your previous GPA and total credits as well.

GPA Formula

GPA = Σ (Grade Points × Credit Hours) ÷ Total Credit Hours

Standard letter grade to grade point conversion (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

Example Calculation

Three courses this semester:

• Math (4 credits) – A = 4.0 → 4.0 × 4 = 16.0 points
• English (3 credits) – B+ = 3.3 → 3.3 × 3 = 9.9 points
• History (3 credits) – B = 3.0 → 3.0 × 3 = 9.0 points
• Total: 34.9 points ÷ 10 credit hours = GPA 3.49

Why Use This Calculator?

Knowing your GPA at any point in the semester lets you make strategic decisions — drop a class, focus effort on high-credit courses, or calculate the grades you need in remaining exams to hit a target GPA.

Common Mistakes to Avoid

• Forgetting to weight by credit hours — a 1-credit pass/fail course affects GPA less than a 4-credit lecture. Always factor in credit hours.
• Mixing 4.0 and percentage scales — the calculator uses the 4.0 scale. If your school uses a different scale (5.0, 10-point, percentages), check the specific conversion chart for your institution.
• Ignoring repeated courses — some schools replace the original grade when you retake a course; others average them. Know your school's policy before calculating.

Frequently Asked Questions

What GPA do I need for the Dean's List?

Most schools require a 3.5 or higher GPA to qualify for the Dean's List, though requirements vary by institution.

What GPA is needed for graduate school?

Most graduate programs look for a minimum 3.0 GPA, though competitive programs (law, medicine, top MBA programs) typically want 3.5 or higher.

How do I raise my GPA?

Focus on high-credit-hour courses (they have more impact on GPA), retake courses where allowed, and use the "what-if" feature in this calculator to target the grades you need.

What is the difference between a semester GPA and cumulative GPA?

Semester GPA only includes the current semester's courses. Cumulative GPA includes all courses taken across all semesters — it's the overall measure colleges and employers see.

Do AP or dual enrollment courses affect my college GPA?

AP exam credit transferred to college usually appears as credit-only (no grade). Dual enrollment courses taken at a college do count toward your college GPA.

Conclusion

Your GPA is a snapshot of your academic performance — and it's something you have more control over than you might think. Use this calculator to track your progress, plan your strategy, and set realistic targets each semester.
