Grade received (A+, A, A-, B+, B, B-, C+, C, C-, D+, D, D-, or F)
Credit Hours (typically 3-4 for semester courses, 1 for labs)

Use "Add Course" to add more rows. The calculator supports unlimited courses.

Click "Calculate GPA" to see results. The output displays:

Your calculated GPA (to two decimal places)
Total credit hours
Total quality points earned
Letter grade distribution
Credit hour distribution
If applicable: grade needed in additional courses to reach a target GPA

The Core Principle: Weighted Average of Grade Points

GPA is a credit-weighted average of your grades. Courses with more credits have proportionally more impact on your GPA.

Each letter grade converts to grade points:

A/A+: 4.0 points
A-: 3.7 points
B+: 3.3 points
B: 3.0 points
B-: 2.7 points
C+: 2.3 points
C: 2.0 points
C-: 1.7 points
D+: 1.3 points
D: 1.0 points
D-: 0.7 points
F: 0.0 points

Quality points = Grade points × Credit hours GPA = Total quality points ÷ Total credit hours

This means an A in a 4-credit course contributes more to your GPA than an A in a 1-credit course.

How to Calculate GPA Manually

Example semester:

Calculus: B+ (3.3), 4 credits
English: A- (3.7), 3 credits
Chemistry: B (3.0), 4 credits
History: A (4.0), 3 credits

Step 1: Calculate quality points for each course

Calculus: 3.3 × 4 = 13.2
English: 3.7 × 3 = 11.1
Chemistry: 3.0 × 4 = 12.0
History: 4.0 × 3 = 12.0

Step 2: Sum quality points Total = 13.2 + 11.1 + 12.0 + 12.0 = 48.3

Step 3: Sum credit hours Total = 4 + 3 + 4 + 3 = 14 credits

Step 4: Calculate GPA GPA = 48.3 ÷ 14 = 3.45

For weighted GPA (5.0 scale): Honors courses add 0.5 to grade points; AP/IB courses add 1.0 An A in AP Calculus = 5.0 points instead of 4.0

Real-World Applications

Academic standing. Many schools require 2.0 GPA for good standing, 3.0 for Dean's List, 3.5 for honors. Know where you stand.

Scholarship eligibility. Scholarships often require minimum GPAs (commonly 3.0 or 3.5). Dropping below costs real money.

Graduate school applications. Competitive programs expect 3.5+ GPAs. Knowing your current GPA helps plan remaining semesters.

Course selection strategy. If your GPA needs help, a 4-credit course with an A helps more than a 1-credit elective with the same grade.

Job applications. Some employers filter by GPA, especially for entry-level positions. Understanding your GPA helps set expectations.

Scenarios People Actually Run Into

The math course disaster. You got a D in a 4-credit math course. To calculate the damage: that D (1.0) contributes 4.0 quality points. If you had gotten a B (3.0), you'd have 12.0 quality points—8 points lost. With 60 total credits, that's 8/60 = 0.13 GPA points lost.

The GPA recovery mission. Your cumulative GPA is 2.5 after 60 credits. You need 3.0 for graduation. How? You need 180 quality points total (3.0 × 60). You currently have 150 (2.5 × 60). You need 30 more points in remaining courses. With 20 credits left, you need an average 3.5 GPA in those courses.

The weighted versus unweighted question. Colleges see both. Your weighted 4.3 shows you took rigorous courses. Your unweighted 3.8 shows your actual grades. Both matter.

The repeating dilemma. You got a D in Biology. Retaking it and getting an A: some schools replace the old grade; others average both. Know your policy before deciding.

The major GPA surprise. Your overall GPA is 3.2, but your major GPA (courses in your major only) is 2.8. Some graduate programs care more about major GPA.

Trade-Offs and Decisions People Underestimate

Course difficulty versus GPA impact. An easy A protects GPA but may not prepare you. A challenging B builds skills but hurts GPA. Strategic course selection balances both.

Credit hours matter. A 4-credit course affects GPA four times as much as a 1-credit course. Choose high-credit courses carefully.

Early semester weight. With few credits, each grade dramatically affects GPA. A freshman C hurts more than a senior C (proportionally). Start strong.

Withdraw versus low grade. A W (withdrawal) doesn't affect GPA but shows on transcript. A D affects GPA but shows completion. Consider context and policies.

Pass/fail options. Pass/fail courses don't affect GPA but don't help it either. Use strategically—for courses you'd otherwise get Cs in, or to explore outside your major.

Common Mistakes and How to Recover

Ignoring credit hours. Treating all courses as equal weight when calculating GPA. Always weight by credits.

Using the wrong scale. Your school uses A+ = 4.3, but you calculated with A+ = 4.0. Know your institution's scale.

Forgetting withdrawn or repeated courses. Some schools exclude Ws from GPA but include them in attempted credits. Know how your school counts.

Not separating major from cumulative GPA. Professional programs often care most about major GPA. Track both.

Miscounting future impact. With 100 credits at 3.0 GPA, getting straight As in 20 more credits only raises GPA to 3.17. The more credits you have, the harder it is to change GPA significantly.

How This Calculator Works

Grade point scales:

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+: 1.3, D: 1.0, D-: 0.7
F: 0.0

5.0 scale (adds 1.0 to each):

A+/A: 5.0, A-: 4.7
B+: 4.3, B: 4.0, B-: 3.7
... etc.

Calculation:

For each course:
  qualityPoints = gradePoints × creditHours
  
totalQualityPoints = sum of all quality points
totalCredits = sum of all credit hours
GPA = totalQualityPoints / totalCredits

Grade distribution: Counts courses at each letter grade level.

Credit distribution: Groups courses by credit hours (1, 2, 3, 4+).

Target GPA calculation:

neededQualityPoints = (targetGPA × (currentCredits + additionalCredits)) - currentQualityPoints
neededGPA = neededQualityPoints / additionalCredits

FAQs

What's a good GPA?

Context-dependent. 3.0 is "B average" and typically meets minimum requirements. 3.5+ is competitive for graduate schools. 3.7+ is honors territory.

How do plus/minus grades affect GPA?

Significantly. The difference between B+ (3.3) and B- (2.7) is 0.6 points—substantial in a single course, meaningful cumulatively.

Does GPA matter after college?

Decreasingly. First job applications may filter by GPA. By 3-5 years of work experience, it rarely matters.

What if my school uses a different scale?

Use your school's conversion. Some use A+ = 4.3; some cap at 4.0. International grades vary widely. Use the scale your school applies.

Can I calculate my GPA without all grades?

For planning, estimate future grades. Enter expected grades and credit hours to see projected GPA.

How do transfer credits affect GPA?

Usually, only credits transfer, not grades. Your GPA at your current institution only includes courses taken there.

What's the difference between unweighted and weighted GPA?

Unweighted uses standard 4.0 scale. Weighted adds bonus points for honors/AP courses, allowing GPAs above 4.0.

How much can one bad grade hurt my GPA?

Depends on total credits. With 30 credits, one D (1.0) in a 3-credit course lowers GPA by about 0.2. With 100 credits, impact is around 0.06.

What GPA do I need for graduate school?

Competitive programs typically expect 3.5+. Some programs have minimum cutoffs (often 3.0). Research your target programs specifically—some weight major GPA more heavily.

Should I retake a class to improve my grade?

Depends on your school's policy. Some replace the old grade entirely; others average both attempts. Even if averaged, improving from D to A significantly helps.

How do pass/fail courses affect GPA?

Pass/fail courses don't affect GPA—the grade isn't converted to points. However, they appear on your transcript and may affect perceptions for graduate school or employers.

Does high school GPA matter for college?

For admissions, yes. Once enrolled in college, your college GPA becomes what matters. High school GPA isn't typically relevant for graduate school or employment after college.

How do I calculate my GPA for a specific subset of courses?

Use the same formula but include only relevant courses. Major GPA uses only courses in your major. Cumulative GPA uses all courses. Some applications ask for both.

What is grade inflation and how does it affect my GPA?

Grade inflation means average grades have risen over time. A 3.5 GPA today may represent different achievement than 3.5 decades ago. Some graduate programs and employers adjust for this by school or over time.

How should I balance GPA versus learning?

GPA matters for some thresholds (scholarships, graduate school cutoffs) but perfect optimization is counterproductive. Challenging courses that teach more may serve you better long-term than easy As. Find your balance.

Can I predict my final GPA before the semester ends?

Yes—calculate using expected grades. If you have 45 credits at 3.2 GPA and expect 15 credits of B+ work this semester (3.3 average), your new cumulative will be approximately (45×3.2 + 15×3.3)/(45+15) = 3.23.

What is academic forgiveness or grade amnesty?

Some schools offer programs allowing students to restart GPA after a gap in enrollment, or to exclude older poor grades from GPA calculation. These programs have specific eligibility requirements and limitations—check with your registrar.

How do graduate schools evaluate international GPAs?

International grading scales vary widely. Many graduate programs use credential evaluation services to convert foreign grades to US equivalents. Some programs focus on class rank or percentile rather than GPA when evaluating international applicants.

What should I do if my GPA is below my target program's average?

Strengthen other application components: standardized test scores, recommendation letters, personal statement, and relevant experience. Some programs offer conditional admission or bridge programs for candidates with lower GPAs but strong potential.
