How to Calculate Your GPA
Your GPA (grade point average) is a single number that summarizes your academic performance. Colleges, scholarships, employers, and graduate programs all look at it. Calculating it is straightforward once you know the formula, but the details (weighted vs. unweighted, semester vs. cumulative) can be confusing. Here is exactly how it works.

Most US schools use a 4.0 scale. Each letter grade corresponds to a number of grade points.
| Letter Grade | Grade Points | Percentage (typical) |
|---|---|---|
| A / A+ | 4.0 | 93 - 100% |
| A- | 3.7 | 90 - 92% |
| B+ | 3.3 | 87 - 89% |
| B | 3.0 | 83 - 86% |
| B- | 2.7 | 80 - 82% |
| C+ | 2.3 | 77 - 79% |
| C | 2.0 | 73 - 76% |
| C- | 1.7 | 70 - 72% |
| D | 1.0 | 60 - 69% |
| F | 0.0 | Below 60% |
The GPA Formula
GPA is a weighted average of your grade points, where the weight is the number of credit hours for each class.
where Grade Points per Class = Grade Value x Credit Hours
Step-by-Step Example
Suppose you take four classes this semester:
| Class | Credits | Grade | Grade Points | Quality Points |
|---|---|---|---|---|
| English 101 | 3 | A (4.0) | 4.0 | 12.0 |
| Biology 201 | 4 | B+ (3.3) | 3.3 | 13.2 |
| History 150 | 3 | A- (3.7) | 3.7 | 11.1 |
| Math 200 | 3 | B (3.0) | 3.0 | 9.0 |
| Totals | 13 | 45.3 |
Total quality points: 12.0 + 13.2 + 11.1 + 9.0 = 45.3. Total credit hours: 13. Semester GPA = 45.3 / 13 = 3.48.
Cumulative GPA
Your cumulative GPA includes all semesters, not just the current one. To calculate it, add up all quality points from every semester and divide by the total credit hours from every semester. If you earned 90.6 quality points over 26 credit hours across two semesters, your cumulative GPA is 90.6 / 26 = 3.48.
Cumulative GPA is what appears on your transcript and what colleges and employers look at. A single bad semester can be overcome if you improve in subsequent semesters, since the cumulative GPA blends everything together.
Weighted vs. Unweighted GPA
Unweighted GPA uses the standard 4.0 scale for all classes. An A in regular English and an A in AP English both count as 4.0.
Weighted GPA gives extra points for honors, AP, and IB classes to reflect their higher difficulty. Common scales add 0.5 points for honors classes and 1.0 point for AP/IB classes, making the maximum possible GPA a 5.0 instead of 4.0. An A in AP English would count as 5.0 instead of 4.0.
Most high schools report weighted GPAs, while most colleges recalculate GPAs using their own scales during admissions. Scholarships may specify which type of GPA they require, so always check the requirements.
What GPA Do You Need for College?
GPA requirements vary widely by institution. Here are general benchmarks for unweighted GPAs:
Highly selective schools (Ivy League, Stanford, MIT): 3.9+ is typical for admitted students, though GPA is only one factor. Selective state universities (UC Berkeley, UMich, UVA): 3.5 to 3.9. Mid-tier state universities: 3.0 to 3.5. Open-admission schools and community colleges: Generally accept all applicants regardless of GPA.
Remember that admissions are holistic at most competitive schools. A 3.6 GPA with challenging coursework, strong test scores, and compelling extracurriculars can be more impressive than a 4.0 with only easy classes.
How to Raise Your GPA
Earlier is easier. With fewer credit hours completed, each class has a bigger impact on your cumulative GPA. Raising a GPA from 2.5 to 3.0 after one semester is much easier than after six semesters.
Focus on high-credit classes. A 4-credit class has more impact on your GPA than a 2-credit class. Performing well in your major courses (which often carry more credits) moves the needle faster.
Retake classes if your school allows it. Many schools let you retake a course and replace the old grade with the new one. If you got a D in a class, retaking it for a B turns that D from 1.0 to 3.0 in your GPA calculation.
Use pass/fail strategically. Some schools allow you to take electives pass/fail, which removes them from your GPA calculation entirely. This can be useful for challenging courses outside your major that might hurt your GPA.
