GPA Calculator

Calculating your semester or cumulative GPA without weighting by credit hours gives you a wrong answer. A 4-credit calculus class with a C affects your GPA more than a 1-credit gym class with an A. This calculator does the math properly: each course's grade points = (letter grade points) × (credit hours), GPA = total grade points / total credit hours. Add as many courses as you need, see your cumulative GPA update in real time. Standard 4.0 scale (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0) with +/- modifiers (B+ = 3.3, B- = 2.7).

Add at least one course with a grade and credits.

Some schools and systems vary slightly — confirm with your registrar. UC and CSU systems in California use different scales for transfer; AP / IB courses often get a +1 weighted bonus in high school ("weighted GPA").

How the math works

Worked example, one semester:

  • Calc II: A (4.0) × 4 credits = 16.0 grade points
  • English 101: B+ (3.3) × 3 credits = 9.9 grade points
  • Chem Lab: A- (3.7) × 1 credit = 3.7 grade points
  • History: C (2.0) × 3 credits = 6.0 grade points
  • Total: 35.6 grade points / 11 credits = 3.24 GPA

A 4-credit A pulls more weight than a 1-credit A — that's why credit weighting matters.

How to use this calculator

  1. Add a course row: pick the letter grade + enter credit hours.
  2. Click "+ Add course" for each additional course in the semester or cumulative period.
  3. Output: cumulative GPA + total grade points + total credits.
  4. For cumulative GPA across semesters: enter all courses from all semesters.

Common scenarios

Strong semester, 15 credits. 3 × A (4.0, 4 cr each) + 1 × B+ (3.3, 3 cr): 48 + 9.9 = 57.9 / 15 = 3.86 GPA. Solid Dean's List territory.

Rough semester, 14 credits. 1 A (4.0 × 3), 1 B (3.0 × 4), 1 C (2.0 × 4), 1 D (1.0 × 3) = 12 + 12 + 8 + 3 = 35 / 14 = 2.50 GPA. Marginal academic standing at most schools.

Recovering from a bad semester. If cumulative is 2.7 after 30 credits (81 points), need next 15 credits at 3.6+ GPA to bring cumulative to 3.0 (45 credits, 135 points needed). Math: 135 – 81 = 54 needed in 15 credits = 3.6 average.

FAQ

What's a good GPA? +
For college: 3.5+ is honors / Dean's List territory at most schools. 3.0-3.5 is solid. Below 3.0 may trigger academic warning or limit graduate school options. For high school: 3.0+ is competitive for state universities; 3.5+ for selective private; 3.8+ for elite admissions.
What's the difference between weighted and unweighted GPA? +
Unweighted: standard 4.0 scale, no bonuses for difficulty. Weighted: honors / AP / IB courses get +0.5 to +1.0 added (A in AP Calc = 5.0 weighted). Most colleges look at both. The unweighted GPA from your transcript is the standardized comparison; weighted GPA shows course rigor.
How are pass/fail courses counted? +
Pass: contributes the credits to total but doesn't add or subtract from GPA. Fail (a P/F course you failed): F grade, 0 points, full credits counted — hurts GPA. Most schools limit how many P/F courses you can take in your major.
How are repeats counted? +
Varies by school. Most common: the original grade stays on the transcript but only the higher (repeated) grade counts toward GPA. Some schools average both grades. Check your registrar's policy for your specific school.
Does an incomplete (I) affect GPA? +
An I doesn't count toward GPA until it's resolved. If you complete the course, it becomes a regular grade. If you don't complete by the deadline, it converts to F at most schools. Avoid incompletes whenever possible.
How do grad school admissions evaluate GPA? +
Graduate programs heavily weight the GPA in your major and the last 60 credits ("upper-division GPA"). They often ignore freshman year general-ed grades if you've shown improvement. A 3.0 cumulative with 3.8 in upper-division is much more attractive than a flat 3.2 across the board.
Can my GPA recover from a 1.5 freshman year? +
Yes — with consistent 3.5+ work afterward. Math: at 1.5 GPA across 30 freshman credits (45 grade points), you need ~3.7+ across 90 more credits (333 points) to graduate cum laude with a 3.15. Possible but requires sustained effort and minimal C grades.
Why is my GPA different in different calculators? +
Different schools use slightly different point scales. Some count A+ as 4.0 (the default), others as 4.3 (extra credit) or even 4.33. Some round to nearest hundredth; some don't. Check your school's official catalog for the exact scale.
