GPA Calculator
Add courses, pick grades, set credit hours — your 4.0-scale GPA updates as you type.
GPA is a credit-weighted average, which is the part that makes it annoying to compute by hand: an A in a 4-credit course moves your average more than an A in a 1-credit lab. This calculator does the weighting properly — add a row per course, pick the letter grade, set the credit hours, and your GPA updates live along with total credits and grade points (the raw number transcripts are built from).
It uses the standard unweighted 4.0 scale that nearly all US colleges share: A = 4.0, A− = 3.7, B+ = 3.3, down to F = 0. Because the calculation runs live, it doubles as a planning tool: add next semester's courses with the grades you expect and see where your GPA lands, or test what grade you'd need in a heavy-credit course to cross a threshold like 3.5 for a scholarship or Dean's List. To combine this semester with your existing record, add one extra row using your cumulative credits and a "grade" close to your current GPA — or compute total grade points by hand: cumulative GPA × cumulative credits, plus this semester's points, divided by combined credits. For percentage-based grading systems, convert scores with the percentage calculator first.
How to use the GPA Calculator
- Add a row for each course — the course name is optional, just for your own tracking.
- Pick the letter grade and enter the credit hours for each course.
- Read your GPA, total credits and grade points below — they update as you type.
- Test scenarios by changing grades: see exactly what an A versus a B in your 4-credit course does.
Frequently asked questions
How is GPA actually calculated?
Each grade converts to points (A = 4.0, B+ = 3.3, etc.), gets multiplied by the course's credit hours, and the total grade points are divided by total credits. Three A's in 3-credit courses and a C in a 1-credit lab: (4+4+4)×3 + 2×1 = 38 points ÷ 10 credits = 3.80.
What's the difference between weighted and unweighted GPA?
Unweighted (this calculator) caps at 4.0 regardless of course difficulty. Weighted GPA — mostly a high-school concept — adds bonus points for honors/AP classes, allowing values above 4.0. Colleges recalculate applicants on their own scales anyway, so the unweighted number is the portable one.
How do I include my cumulative GPA from previous semesters?
Multiply your cumulative GPA by your cumulative credits to get existing grade points; add this semester's grade points (shown below the table); divide by the combined credits. Example: 3.4 × 60 credits = 204 points, plus a 45-point semester over 12 credits → 249 ÷ 72 = 3.46.
Do pass/fail or withdrawn courses count?
Typically no — P, W and transfer credits usually earn credit hours without grade points and are excluded from GPA. Leave them out here. An F, however, very much counts: zero points across all its credits.
What GPA do common thresholds require?
Typical US benchmarks: 2.0 to stay in good academic standing, 3.0 for many graduate programs, 3.5+ for Dean's List at many schools, and 3.7+ competitive for top scholarships. Requirements vary by institution — check yours.
