About GPA Calculator
This GPA calculator lets you enter grades and course credits to estimate your grade point average.
It is useful for semester planning, academic tracking and checking how individual classes affect your overall GPA.
GPA Calculation Formula
// GPA = Total Grade Points / Total Credits // For each course: grade_points × credits // Standard 4.0 scale: // A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0 // Example calculation: // Course 1: A (4.0) × 3 credits = 12.0 points // Course 2: B (3.0) × 4 credits = 12.0 points // Course 3: C (2.0) × 2 credits = 4.0 points // Total: 28.0 points / 9 credits = 3.11 GPA
Grade Point Values Reference
| Letter | Points | Percentage |
|---|---|---|
| A | 4.0 | 90-100% |
| A- | 3.7 | 87-89% |
| B+ | 3.3 | 83-86% |
| B | 3.0 | 80-82% |
| B- | 2.7 | 77-79% |
| C+ | 2.3 | 73-76% |
| C | 2.0 | 70-72% |
| C- | 1.7 | 67-69% |
| D+ | 1.3 | 63-66% |
| D | 1.0 | 60-62% |
| F | 0.0 | 0-59% |
Cumulative GPA Update Formula
// New Cumulative GPA = (old_gpa × old_credits + new_points) / (old_credits + new_credits) // Example: // Current: 3.0 GPA over 60 credits // Semester: 15 credits with 3.8 GPA (57 points) // New GPA = (3.0 × 60 + 57) / (60 + 15) = 237/75 = 3.16
Frequently Asked Questions
- How is GPA calculated using grade points and credits?
- GPA = Total Grade Points / Total Credits. For each course, multiply grade points (A=4, B=3, C=2, D=1, F=0) by course credits. Sum all grade points and divide by total credits. Example: A in 3-credit course (4×3=12) + B in 4-credit course (3×4=12) = 24/7 = 3.43 GPA.
- What is the difference between unweighted and weighted GPA?
- Unweighted GPA uses standard 4.0 scale for all courses. Weighted GPA adds bonus points for honors/AP/IB courses (often +0.5 or +1.0). An A in AP class might be worth 5.0 instead of 4.0. Weighted GPA can exceed 4.0, reflecting course difficulty. This calculator uses unweighted 4.0 scale.
- How do plus/minus grades affect GPA?
- Many schools use finer grade 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. This provides more granularity. Example: B+ (3.3) in a 3-credit course = 9.9 grade points. Check your institution's specific scale as it varies.
- How do you calculate semester GPA vs cumulative GPA?
- Semester GPA uses only that term's courses. Cumulative GPA includes all courses taken. To find new cumulative: (old GPA×old credits + new grade points) / (old credits + new credits). Example: 3.0 GPA over 30 credits + 12 credits at 3.5 = (90+42)/42 = 3.14 new cumulative.
- What GPA is needed for academic honors?
- Requirements vary by institution. Common thresholds: Dean's List 3.5+, Cum Laude 3.5-3.69, Magna Cum Laude 3.7-3.89, Summa Cum Laude 3.9+. Graduate programs often require 3.0 minimum. Scholarship requirements range from 2.5 to 4.0. Check your specific program's requirements.
- How can I raise my GPA faster?
- Take more credits in high-performing subjects, retake low-grade courses if allowed, focus on high-credit courses, and maintain consistency. A student with 2.8 GPA over 60 credits needs 90 credits at 4.0 to reach 3.4. The more credits completed, the harder it is to shift GPA significantly.
