How the GPA Calculator Works
This calculator computes both your unweighted and weighted GPA using the standard 4.0 scale. Add each course with its letter grade, credit value, and course level (Regular, Honors, or AP/IB). The tool converts letter grades to grade points, applies the level bonus, and divides total points by total credits to produce both GPA values instantly.
Honors courses receive a +0.5 bonus per grade (e.g., a B becomes 3.5 instead of 3.0). AP and IB courses receive a +1.0 bonus. Regular courses use the standard point value. The weighted GPA reflects your total academic rigor, while the unweighted GPA shows your raw performance across all courses.
Tips for Using Your GPA Results
- Track each semester separately — Enter courses from one term at a time to see how each semester affects your cumulative GPA.
- Experiment with what-if scenarios — Change a grade from B to A to see how much your GPA would improve. This helps prioritize which classes to focus on.
- Understand your school's policy — Some schools cap weighted GPA or use different bonus values. Check with your guidance counselor to confirm the weighting applied at your school.
Frequently Asked Questions
What is the difference between unweighted and weighted GPA?
Unweighted GPA uses a standard 4.0 scale where an A is 4.0 regardless of course difficulty. Weighted GPA adds extra points for harder courses: +0.5 for Honors and +1.0 for AP or IB classes. A weighted GPA can exceed 4.0, which helps colleges see that you challenged yourself academically.
How is GPA calculated on a 4.0 scale?
Each letter grade maps to a numeric value: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. For weighted GPA, add the course level bonus before multiplying by credits. Then divide total grade points by total credits. For example, an A in an AP course (4.0 + 1.0 = 5.0 grade points) times 1 credit gives 5.0 points.
Do colleges look at weighted or unweighted GPA?
Most colleges consider both. Unweighted GPA shows your baseline academic performance, while weighted GPA reflects course rigor. Admissions officers also recalculate GPA using their own formulas, so the best strategy is to take challenging courses and perform well in them.
How many credits should I assign to each course?
Most high school courses are 1 credit for a full-year class or 0.5 credits for a semester. College courses vary (typically 3 or 4 credits per class). Use the credits as they appear on your transcript for the most accurate calculation.
