GPA is calculated as the weighted average of your grades, where each course is weighted by its credit hours. A=4.0, A−=3.7, B+=3.3, B=3.0, B−=2.7, C+=2.3, C=2.0, D=1.0, F=0.0.

What is the GPA Calculator?

A GPA (Grade Point Average) is a numerical representation of academic performance calculated by weighting each course grade by its credit hours, then dividing the total grade points by total credits. Most systems use a 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0), though some institutions use different scales. GPA summarises performance across multiple courses into one comparable metric.

How it works

The calculator multiplies each grade's point value by the course's credit hours to get grade points, sums all grade points, then divides by total credit hours. For example, an A (4.0) in a 3-credit course contributes 12 grade points; a B (3.0) in a 4-credit course contributes 12 grade points. Add all grade points and divide by total credits to get your GPA.

GPA = (Sum of Grade Points) / (Sum of Credit Hours) Grade Points = Grade Value × Credit Hours

Grade Value is the numeric equivalent of your letter grade (typically 4.0 for A, 3.0 for B, etc.). Credit Hours is the number of hours the course is worth—usually 1–4 hours depending on course difficulty and duration.

Examples

InputResultNotes
Two courses: A (4.0) in 3-credit Chemistry, B (3.0) in 4-credit HistoryGPA = (12 + 12) / 7 = 3.43Each course's impact depends on its credit weight; Chemistry and History contribute equally here despite different letter grades.
Three courses: A (4.0) in 4 credits, A (4.0) in 3 credits, B (3.0) in 4 creditsGPA = (16 + 12 + 12) / 11 = 3.64Harder courses (more credits) carry more weight; dropping from A to B in a 4-credit course costs more GPA points.
Four courses: A (4.0) in 3 credits, B (3.0) in 3 credits, C (2.0) in 2 credits, B (3.0) in 4 creditsGPA = (12 + 9 + 4 + 12) / 12 = 3.08A single C grade pulls down your average; passing the B in the heaviest course (4 credits) provides the most cushion.

How to use the GPA Calculator

  1. List each course you've taken with its letter grade and credit hours
  2. Convert each letter grade to its numeric value (typically 4.0 = A, 3.0 = B, 2.0 = C, 1.0 = D, 0.0 = F)
  3. Multiply each grade value by the course's credit hours to get grade points
  4. Sum all grade points and sum all credit hours
  5. Divide total grade points by total credit hours
  6. Round to two decimal places for your final GPA

Benefits

  • Track semester progress instantly without manual arithmetic
  • See which courses impact your overall average most (credit-weighted view)
  • Simulate grades for remaining courses to understand what's needed to reach a target GPA
  • Compare performance across semesters (cumulative vs. semester GPA)
  • Prepare accurate transcripts for college applications, scholarships, or job submissions
  • Identify weak subjects early and adjust study strategy before final exams

Tips & common mistakes

Common mistakes

  • Treating all courses equally—a 4-credit course impacts GPA 4× more than a 1-credit course
  • Using the wrong grade scale (some schools use ±modifiers: A− = 3.7; check your institution's official scale)
  • Forgetting to include passed/failed courses or transfer credits, which may or may not count towards GPA depending on institutional policy

Tips

  • Save your grade sheet as you go each semester—it's easier to recalculate and spot trends over time
  • Target GPA = 3.7 or above for most competitive scholarships and graduate school admissions
  • If you've retaken a course, check whether your school counts the highest grade, the latest grade, or both
  • Recalculate quarterly to catch any data entry errors before transcript deadlines

Frequently asked questions

What's the difference between semester GPA and cumulative GPA?

Semester GPA includes only courses from one term; cumulative GPA sums all grades across all terms. You'll typically report cumulative GPA on applications.

Do pass/fail courses affect my GPA?

Most institutions exclude pass/fail courses from GPA calculation. Confirm with your registrar, as policies vary.

Can I recalculate GPA if I retake a course?

Yes—many schools average both grades or count only the higher grade. Check your institution's retake policy; the calculator can include both attempts if needed.

What GPA do I need for a scholarship?

Merit scholarships typically require 3.5–4.0; some state grants need 2.0–3.0. Scholarships vary widely; check specific award requirements.

Is GPA the only factor in admissions?

No. Colleges also weigh test scores, essays, extracurriculars, and context. GPA is important but not decisive alone.

How does credit weighting work?

A course's credit hours multiply its grade value—so an A in a 4-credit course (16 points) counts twice as much as an A in a 2-credit course (8 points).
