Calculateur GPA

GPA (Grade Point Average) is the standard academic performance metric for US universities, but the calculation rules vary by institution — weighted vs unweighted, different grade-to-point mappings, and credit-hour weighting. Our calculator handles all common GPA scales (4.0, 4.3 with A+, 5.0 weighted for AP/IB) and cumulative GPA across multiple semesters.

À propos de GPA Calculator

GPA (Grade Point Average) is the standard academic performance metric for US universities, but the calculation rules vary by institution — weighted vs unweighted, different grade-to-point mappings, and credit-hour weighting. Our calculator handles all common GPA scales (4.0, 4.3 with A+, 5.0 weighted for AP/IB) and cumulative GPA across multiple semesters.

Comment l'utiliser

  1. Add each course: course name, grade (letter or percentage), and credit hours.
  2. See semester GPA and cumulative GPA updated in real time.
  3. Use the "what-if" mode: find what grades you need in remaining courses to hit a target GPA.
  4. Switch between 4.0 (standard), 4.3 (with A+), and 5.0 (weighted AP/IB) scales.

Formule et méthodologie

Grade points: 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. Quality points = grade points × credit hours. Semester GPA = Σ(quality points) ÷ Σ(credit hours). Cumulative GPA = Σ(all quality points) ÷ Σ(all credit hours). Weighted GPA adds 1.0 for AP/IB courses on a 4.0 scale.

Cas d'usage courants

  • Tracking GPA semester-by-semester for scholarship eligibility
  • Graduate school application: calculating cumulative GPA for applications
  • Academic probation: determining minimum GPA to exit probation status
  • Honor roll and Dean's List: checking whether current GPA qualifies
  • Dual enrollment: combining high school and college course GPAs

Questions fréquentes

On a standard 4.0 scale: no — both A and A+ are worth 4.0 quality points. On a 4.3 scale (used by some high schools and colleges): A+ = 4.3, A = 4.0, A- = 3.7. Graduate schools and most US universities use the 4.0 scale where A+ provides no numerical benefit. Check your institution's grading policy — some schools don't even award A+ grades.
It depends on how many total credit hours you've completed. The more hours, the more diluted any single semester is. After 30 credit hours, one 15-credit semester moves GPA by at most 0.5 points. After 90 hours, the same semester moves it by ~0.15 points. Early semesters matter most — a bad first semester is hard to recover from, but a great first semester provides a cushion. Use the what-if calculator to see the math for your specific situation.
