GPA Calculator (Weighted and Unweighted)
Your GPA is one of the most frequently referenced numbers in college admissions, yet many students don’t fully understand how it’s calculated. This guide breaks down weighted and unweighted GPA, walks you through the math, and provides a tool to calculate yours instantly.
Weighted vs. Unweighted GPA: What’s the Difference?
Unweighted GPA uses a standard 4.0 scale. Every class is graded the same way regardless of difficulty.
Weighted GPA accounts for course rigor. Honors, AP, and IB courses receive additional grade points, so your GPA can exceed 4.0. Most weighted scales top out at 5.0.
Standard Unweighted Grade Scale
| Letter Grade | Grade Points |
|---|---|
| A / A+ | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D | 1.0 |
| F | 0.0 |
Weighted Grade Scale Additions
| Course Level | Grade Points Added |
|---|---|
| Regular / College Prep | +0.0 (standard scale) |
| Honors | +0.5 (A = 4.5) |
| AP / IB | +1.0 (A = 5.0) |
How to Calculate Your GPA Manually
Three steps:
- Assign grade points to each course. For weighted GPA, add bonus points for honors, AP, or IB courses.
- Multiply each course’s grade points by its credit hours.
- Divide the total grade points by total credit hours.
Example Calculation: 6 Courses
| Course | Grade | Credit Hours | Unweighted Points | Weighted Points |
|---|---|---|---|---|
| AP English Literature | A (4.0) | 1.0 | 4.0 | 5.0 |
| Honors Chemistry | B+ (3.3) | 1.0 | 3.3 | 3.8 |
| AP U.S. History | A- (3.7) | 1.0 | 3.7 | 4.7 |
| Pre-Calculus | B (3.0) | 1.0 | 3.0 | 3.0 |
| Spanish III | A (4.0) | 1.0 | 4.0 | 4.0 |
| Art Studio | A (4.0) | 1.0 | 4.0 | 4.0 |
| Totals | 6.0 | 22.0 | 24.5 |
- Unweighted GPA: 22.0 / 6.0 = 3.67
- Weighted GPA: 24.5 / 6.0 = 4.08
What Colleges Actually See
Many selective colleges recalculate your GPA using their own formula. Some strip out non-academic courses (PE, art electives), while others only consider core subjects. Your school-reported GPA and the GPA a college calculates may differ. Focus on earning strong grades in rigorous courses rather than chasing a specific number.
Average GPAs at Highly Selective Schools
| School | Average Unweighted GPA | Average Weighted GPA |
|---|---|---|
| Harvard | 3.9+ | 4.2+ |
| Stanford | 3.9+ | 4.2+ |
| MIT | 3.9+ | 4.2+ |
| UCLA | 3.8+ | 4.1+ |
| University of Michigan | 3.8+ | 4.0+ |
| University of Virginia | 3.7+ | 4.0+ |
| University of Texas at Austin | 3.6+ | 3.9+ |
Note: These are approximate midpoint ranges based on admitted student profiles and vary by year.
How to Improve Your GPA
- Prioritize current courses. A strong junior year can offset a weaker freshman year — admissions officers value upward trends.
- Take rigorous courses strategically. A B+ in AP often carries more weight than an A in a regular class.
- Use your school’s resources. Tutoring centers, teacher office hours, and study groups exist for a reason.
- Stay consistent. A steady 3.7 across four years can be more compelling than a 3.9 that dips to 3.4 senior year.

An interactive GPA calculator will be embedded here. Users will be able to enter their courses, grades, credit hours, and course levels (Regular, Honors, AP/IB) to calculate both weighted and unweighted GPA instantly.
Key Takeaways
- Unweighted GPA uses a 4.0 scale; weighted GPA adds points for advanced coursework and can exceed 4.0.
- Many colleges recalculate your GPA using their own formulas, so course rigor matters as much as the number itself.
- An upward trend in grades can partially offset a lower cumulative GPA.
- Use this calculator as a starting point, then verify how your target schools evaluate transcripts.
