Calculate semester or cumulative GPA
Add your courses, choose letter grades or enter percentages, and include previous GPA details only if you want the cumulative result.
How this GPA calculator works
Each course contributes grade points based on its grade and credit hours. The calculator multiplies grade points by credits for every course, adds those values together, and divides by total semester credits.
If you enter a percentage grade instead of a letter, the calculator first converts the percentage into a common letter-grade range. That converted letter grade is then mapped to grade points like A = 4.0, B+ = 3.3, and C = 2.0.
Cumulative GPA works by combining your previous GPA and completed credits with your current semester totals. That gives you a forward-looking estimate before official transcripts update.
Frequently Asked Questions
GPA is calculated by multiplying each course's grade points by its credit hours, adding those totals, and dividing by total credit hours.
Yes. This calculator converts common percentage ranges into letter-grade equivalents before assigning grade points.
Cumulative GPA combines your previous GPA and completed credits with your current semester GPA and semester credits.
Credit hours weight each course so a 4-credit class affects GPA more than a 1-credit class.
