GPA Calculator
Enter your courses — one per line with the grade and credit hours — and get your weighted GPA on the 4.0 or 4.3 scale, plus the grades you need next term to reach a target.
Unweighted calculation — honors/AP boosts are school-specific and not applied.
Formula and calculation
Worked example
For A (3 cr), B+ (4 cr), A− (3 cr) and B (4 cr) on the 4.0 scale: (4.0×3 + 3.3×4 + 3.7×3 + 3.0×4) ÷ 14 = 48.3 ÷ 14 = 3.45 across 14 credits.
How much can one term move your GPA?
The more credits you already have, the slower the cumulative GPA moves — that is arithmetic, not opinion. Adding 15 credits to 30 shifts it by about a third of the gap between your current and next-term averages; by the time you have 90 credits, a single term moves it by less than a tenth. Use the target row here to see what a realistic term looks like, and remember that most graduate programs and scholarships care about your cumulative number, not the story behind it.
What the results mean
- GPA
- Your grade point average for the courses entered, weighted by credit hours: each grade is worth its point value times the course credits, divided by total credits.
- Total credits
- Total credit hours across the courses you entered.
- Courses counted
- How many course lines were counted — blank lines are ignored.
- Rough percentage equivalent
- A rough percentage equivalent, assuming the usual linear mapping (GPA ÷ scale × 100). Real percentage conversions differ by school.
- Needed next term (15 credits) to reach target
- The GPA you need across your next term's credits — here estimated at 15 new credits — for your cumulative GPA to reach the target. Above the scale maximum means the target is out of reach this term.
Frequently asked questions
How is GPA calculated from letter grades?
Each letter grade converts to points (A = 4.0, B = 3.0 and so on, with +/− steps of 0.3), those points are multiplied by the course's credit hours, and the total is divided by all credits. An A in a 4-credit course pulls your GPA more than an A in a 1-credit course.
What GPA do I need next semester to reach my target?
Enter your current GPA, credits earned and your target. The calculator works out the average you need across the next term's credits. If it shows above 4.0 (or your scale's maximum), the target needs more than one term — or fewer hard courses.
Is a W or P/F course counted in GPA?
No. Withdrawals and pass/fail grades carry no grade points and are generally excluded from GPA — leave them out of the course list. Only graded courses affect the average.
Are weighted honors or AP courses handled?
Partially — the 5.0 scale option maps letter grades on a weighted scale (A = 5.0). Actually boosting individual honors courses is school-specific, so if your transcript already lists the weighted points, use those numbers on a compatible scale.
