GPA Calculator
A GPA calculator computes your Grade Point Average from course grades and credit hours. Add your courses below with their letter grades and credit hours to instantly calculate your semester GPA or cumulative GPA on the standard 4.0 scale.
What Is a GPA Calculator?
A GPA calculator takes your letter grades and credit hours for each course and computes your Grade Point Average using the standard 4.0 scale used by most colleges and universities in the United States. The calculator multiplies each course's grade points by its credit hours to produce quality points, sums the quality points across all courses, then divides by the total number of credit hours. The result is your semester GPA. If you enter your prior cumulative GPA and total credits, the calculator also computes your updated cumulative GPA.
GPA is used by colleges to track academic standing, by employers reviewing transcripts, and by graduate schools setting admission benchmarks. Understanding how GPA is calculated helps you plan which courses to prioritize, estimate the impact of dropping a class, and project what grades you need to reach a specific target GPA.

GPA Scale (4.0 Scale)
The standard 4.0 GPA scale assigns a numeric grade point value to each letter grade. Most colleges in the United States use this scale. Some schools do not use plus and minus grades, in which case A, B, C, D, and F each receive a single point value.
| Letter Grade | Grade Points | Percentage Range | Description |
|---|---|---|---|
| A | 4.0 | 93–100% | Excellent |
| A- | 3.7 | 90–92% | Excellent minus |
| B+ | 3.3 | 87–89% | Good plus |
| B | 3.0 | 83–86% | Good |
| B- | 2.7 | 80–82% | Good minus |
| C+ | 2.3 | 77–79% | Average plus |
| C | 2.0 | 73–76% | Average / Satisfactory |
| C- | 1.7 | 70–72% | Average minus |
| D+ | 1.3 | 67–69% | Below average plus |
| D | 1.0 | 63–66% | Below average |
| D- | 0.7 | 60–62% | Below average minus |
| F | 0.0 | Below 60% | Failing |
How to Calculate GPA
Step-by-Step GPA Calculation
To calculate your GPA manually, follow these steps for each course: find the grade point value for your letter grade (use the table above), multiply it by the number of credit hours for that course to get the quality points, then sum all quality points and divide by the total number of credit hours. The formula is:
For example: if you took English (A, 3 credits), Math (B+, 4 credits), and History (B-, 3 credits), your quality points are (4.0 × 3) + (3.3 × 4) + (2.7 × 3) = 12 + 13.2 + 8.1 = 33.3. Total credits are 3 + 4 + 3 = 10. GPA = 33.3 ÷ 10 = 3.33.
Quality Points Explained
Quality points are the product of a course's grade points and its credit hours. A 4-credit course where you earn an A (4.0) produces 16 quality points, while the same course with a B (3.0) produces only 12. This means high-credit courses have a disproportionate impact on your GPA. A strong grade in a 4-credit course improves your GPA more than the same grade in a 1-credit seminar. This weighting reflects the time commitment of each course.
Cumulative GPA
How to Calculate Cumulative GPA
Cumulative GPA combines all semesters of course work into one average. It is calculated the same way as semester GPA, but using all quality points and credit hours earned across every term. To update your cumulative GPA after a new semester, add the new semester's quality points to all previous quality points, and divide by the total credits including the new semester.
Combining Semesters
When combining multiple semesters, it is important to use the total quality points and credits from each term, not to simply average the semester GPAs. Averaging semester GPAs gives incorrect results when semesters have different credit loads. The GPA calculator above handles this correctly when you enter your prior cumulative GPA and total credits earned.
Weighted vs Unweighted GPA
In college, the term "weighted GPA" is less common than in high school. At the college level, all courses are generally treated equally on the 4.0 scale. The weighting comes from credit hours — a 4-credit course already carries more weight than a 2-credit course because it contributes more quality points. Some graduate programs and law schools use a weighted GPA that accounts for course difficulty, but the standard undergraduate GPA is unweighted by difficulty and only weighted by credit hours.
In high school, weighted GPAs assign extra points for Advanced Placement (AP) or honors courses, sometimes scaling up to 5.0. Colleges typically recalculate applicant GPAs on their own unweighted 4.0 scale to compare students fairly across different high school grading systems.
College GPA Requirements
Cum Laude Thresholds
Latin honors are awarded at graduation based on cumulative GPA, though thresholds vary by institution. Common benchmarks at most four-year universities are: Cum Laude (with honor) — typically 3.5 to 3.6 GPA minimum; Magna Cum Laude (with great honor) — typically 3.7 to 3.8 GPA minimum; Summa Cum Laude (with highest honor) — typically 3.9 to 4.0 GPA. Some schools set thresholds based on class rank percentile rather than a fixed GPA cutoff. Always check your specific institution's current requirements, as these thresholds can differ significantly.
Dean's List
The Dean's List is a per-semester academic honor awarded to students who achieve a high GPA in that term while carrying a minimum number of credit hours. Most schools require a semester GPA of 3.5 or higher while enrolled in at least 12 credit hours. Some schools set the threshold at 3.6 or 3.75. Dean's List recognition appears on transcripts and is valued by employers and graduate programs as evidence of consistent academic performance.
Academic Probation
Academic probation is imposed when a student's cumulative GPA falls below the institutional minimum, typically 2.0 on the 4.0 scale. Students on probation may be required to meet with an academic advisor, limit their course load, and achieve a specific semester GPA to return to good standing. Continued academic probation can result in suspension or dismissal. If you are approaching a 2.0 cumulative GPA, use the GPA calculator to determine exactly what grades you need in upcoming semesters to recover.

How to Raise Your GPA
Raising a low cumulative GPA requires sustained high performance because early credits continue to weigh down the average. The more credits you have already completed, the harder it is to move your cumulative GPA significantly. To calculate how many credits you need at what GPA to reach a target: use the formula Target Cumulative GPA × (Prior Credits + X) = Prior Quality Points + (Target Semester GPA × X), then solve for X. In practice, this means:
- Prioritize high-credit courses — Earning an A in a 4-credit class improves your GPA more than an A in a 1-credit elective.
- Retake courses where allowed — Many schools allow grade replacement for retaken courses, which recalculates your GPA using the higher grade.
- Take courses in your strengths — A semester with a 4.0 in courses you excel at moves your cumulative GPA faster than a 3.0 across all courses.
- Use academic support resources — Tutoring, office hours, and study notes generators improve grade outcomes without adding courses.
- Withdraw strategically — Withdrawing from a course before the deadline avoids a failing grade but does not affect GPA. Weigh this against the impact on credit completion timelines.
Frequently Asked Questions
What is a 3.5 GPA?
A 3.5 GPA on the 4.0 scale is equivalent to a B+ average. It typically corresponds to a percentage range of about 87 to 89 percent. A 3.5 GPA qualifies for the Dean's List at most universities, and it meets the minimum cumulative GPA threshold for Cum Laude honors at many institutions. For graduate school applications, a 3.5 is generally considered competitive for most programs.
How do you calculate GPA?
To calculate GPA: assign each letter grade its point value (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0, with plus/minus adjustments). Multiply each grade point value by the course's credit hours to get quality points. Sum all quality points and divide by the total number of credit hours. The result is your GPA. Use the calculator on this page to do this automatically for up to 12 courses.
What GPA is required for Dean's List?
Most colleges require a minimum semester GPA of 3.5 while enrolled in at least 12 credit hours to qualify for the Dean's List. Some institutions set the threshold at 3.6 or higher, and some require a minimum number of courses rather than credit hours. Dean's List requirements are set per semester, not based on cumulative GPA, so it is possible to make the Dean's List even if your cumulative average is lower.
What is cum laude GPA?
Cum Laude ('with honor') typically requires a cumulative GPA of 3.5 to 3.6 at graduation, though the exact threshold varies by institution. Magna Cum Laude ('with great honor') generally requires 3.7 to 3.8, and Summa Cum Laude ('with highest honor') usually requires 3.9 to 4.0. Some schools base these distinctions on class rank percentile rather than a fixed GPA threshold.
Can I raise my GPA from 2.0 to 3.0?
Yes, but it requires significant sustained effort and depends on how many credits you have completed. If you have earned 60 credits at a 2.0 cumulative GPA (120 quality points), you would need to earn approximately 60 more credits with a 4.0 GPA to raise your cumulative to 3.0. In practice, raising from 2.0 to 3.0 is realistic with consistent high performance over two to three semesters if you are early in your degree, and more difficult but possible if you are further along.
