About This Calculator
This GPA calculator helps you compute your grade point average on the standard 4.0 scale used by most colleges and universities. Your GPA is calculated by multiplying each course's grade points by its credit hours, summing those values, and dividing by the total credit hours attempted.
For example, an A (4.0) in a 3-credit course contributes 12.0 grade points, while a B (3.0) in a 4-credit course contributes 12.0 grade points. Your GPA is the total grade points divided by total credits.
To calculate your cumulative GPA, enable the cumulative option and enter your existing GPA and total credits earned. The calculator will combine your previous academic record with the new courses to give you an updated overall GPA.

About This Calculator
This GPA calculator computes your grade point average on the standard 4.0 scaleused by most American colleges and universities. Enter your courses, select the letter grade you earned in each, and specify the number of credit hours. The calculator instantly returns your semester GPA along with your cumulative GPA if you provide your prior academic record. Whether you're a college freshman checking your first-semester standing or a senior projecting the GPA you need to graduate with honors, this tool gives you the answer in seconds.
GPA matters because it is the single most common metric schools, employers, and graduate programs use to evaluate academic performance. Scholarships, dean's list eligibility, academic probation thresholds, and graduate-school admissions cutoffs are all tied to your GPA. Understanding exactly how it is calculated — and what you can do to move the number — puts you in control of your academic trajectory.
How GPA is calculated
Your GPA is a weighted average of the grades you earn, where the weight is the number of credit hours each course carries. The formula is straightforward: for every course, multiply the grade value (on a 4.0 scale) by the credit hours to get quality points. Then add up all the quality points and divide by the total credit hours attempted.
GPA = Total Quality Points / Total Credit Hours
For example, suppose you take three courses this semester: an English class (3 credits, grade A = 4.0), a Chemistry class (4 credits, grade B+ = 3.3), and a History class (3 credits, grade A- = 3.7). Your quality points would be (3 x 4.0) + (4 x 3.3) + (3 x 3.7) = 12.0 + 13.2 + 11.1 = 36.3. Divide by total credits (3 + 4 + 3 = 10) and your semester GPA is 3.63. Credit-heavy courses have a larger impact on your GPA, which is why a low grade in a 4-credit lab science hurts more than the same grade in a 1-credit seminar.
The standard 4.0 grading scale
Most U.S. institutions use the following mapping from letter grades to 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+ = 1.3, D = 1.0, D- = 0.7, and F = 0.0. Some schools treat an A+ as 4.3, though this is uncommon and not reflected in most official transcript GPAs.
Pass/fail courses and withdrawals typically do not factor into your GPA because they carry no grade points, but they may still affect credit-hour totals or financial-aid standing depending on your institution's policies. Incomplete grades usually convert to an F if the work is not finished within the allowed time frame, which can significantly damage your GPA. Always check with your registrar's office for your school's specific grading policies.
Weighted vs. unweighted GPA
The calculator on this page uses the unweighted 4.0 scale, which is the standard at virtually every college and university. However, many high schools report a weighted GPA on a 5.0 (or sometimes 6.0) scale. In a weighted system, honors courses add 0.5 to the grade value and AP or IB courses add 1.0. So an A in an AP class is worth 5.0 instead of 4.0, and a B is worth 4.0 instead of 3.0.
Weighted GPAs reward students for taking more rigorous coursework. A student with a 4.3 weighted GPA has been earning mostly A's in advanced classes, while a 4.0 unweighted GPA means straight A's regardless of course difficulty. College admissions officers are well aware of the difference and will typically look at both your unweighted GPA and the rigor of your course load. If you need to calculate a weighted GPA, add 0.5 or 1.0 to each grade value for honors/AP courses before running the numbers through the same quality-points formula.
Cumulative vs. semester GPA
Your semester GPA reflects only the courses you took in a single term. Your cumulative GPAis the running average across every semester you've completed at your institution. Employers and graduate programs almost always ask for your cumulative GPA, and that is the number that appears on your official transcript.
To calculate your cumulative GPA, you need your previous cumulative GPA and the total number of credit hours you've already completed. Multiply the old GPA by the old credits to recover your historical quality points, then add the new semester's quality points and divide by the combined credit total. This calculator handles that math automatically when you check the "Include cumulative GPA calculation" box and enter your prior GPA and credits.
Keep in mind that as you accumulate more credits, each new semester has a smaller marginal effect on your cumulative GPA. A bad semester early in your college career is easier to recover from than one late in your senior year, simply because you have more future credits to dilute it.
What is a good GPA and how to raise yours
What counts as a "good" GPA depends on context. At most four-year universities, a 3.0 (B average) is considered solid, a 3.5 or above often qualifies for the dean's list, and a 3.7-3.8+ puts you in range for summa cum laude or magna cum laude honors at graduation. For graduate school admissions, competitive programs typically expect a 3.3 or higher, while top-tier programs (medical, law, MBA) often look for 3.5-3.9+. Employers in fields like finance, consulting, and engineering may use 3.0 or 3.5 as screening cutoffs for entry-level roles.
If your GPA is lower than you'd like, there are concrete strategies to improve it. Retake failed or low-grade courses — many schools replace the old grade with the new one in your GPA calculation. Prioritize high-credit courses because an A in a 4-credit class contributes twice the quality points of an A in a 2-credit class. Use the cumulative GPA featurein this calculator to model "what if" scenarios: enter your current GPA and credits, then plug in the grades you're aiming for to see how your cumulative GPA would change.
Other proven tactics include attending office hours, forming study groups, starting assignments early, and taking advantage of tutoring centers. Academic advisors can also help you choose a course load that balances difficulty with your strengths. Small, consistent improvements each semester compound over time — even moving from a B- to a B in every class raises your GPA by 0.3 points.
Frequently Asked Questions
What does GPA stand for?
GPA stands for Grade Point Average. It is a numerical representation of a student’s academic performance, calculated by averaging the grade points earned across all courses, weighted by the number of credit hours each course carries.
How do I calculate my GPA manually?
For each course, multiply the grade value (e.g., A = 4.0, B = 3.0) by the number of credit hours to get quality points. Add up all the quality points, then divide by the total number of credit hours attempted. The result is your GPA on a 4.0 scale.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses the standard 4.0 scale for all classes. A weighted GPA adds extra points for advanced courses: typically 0.5 extra for honors classes and 1.0 extra for AP or IB classes, resulting in a scale that can go up to 5.0 or higher. Colleges usually recalculate your GPA on an unweighted scale during admissions.
Do plus and minus grades affect my GPA?
Yes. At most institutions, an A- is worth 3.7 instead of 4.0, a B+ is 3.3 instead of 3.0, and so on. Plus/minus grading can raise or lower your GPA by up to 0.3 points per course compared to a straight letter-grade system. Check whether your school uses plus/minus grading, as not all do.
What GPA do I need for the dean’s list?
Dean’s list requirements vary by school, but the most common threshold is a semester GPA of 3.5 or higher while taking a full course load (usually 12+ credit hours). Some schools require a 3.7 or even a 3.8. Check your institution’s academic policies for the exact requirement.
How does cumulative GPA differ from semester GPA?
Semester GPA reflects only the grades from a single term. Cumulative GPA is the overall average across all semesters you have completed. Your cumulative GPA is what appears on your transcript and what employers and graduate schools typically evaluate.
Can I raise my GPA after a bad semester?
Yes. The most effective strategies are retaking courses where your school allows grade replacement, prioritizing high-credit courses where you can earn strong grades, and consistently improving each semester. The earlier the bad semester occurred, the more future credits you have to dilute its impact on your cumulative GPA.
Do pass/fail courses affect my GPA?
Typically no. Pass/fail (or credit/no-credit) courses are usually excluded from GPA calculations because no grade points are assigned. However, a failing grade in a pass/fail course may still appear as an F and count toward your GPA at some institutions. Always verify your school’s specific policy.
What GPA do I need for graduate school?
Most graduate programs require a minimum GPA of 3.0, but competitive programs often expect higher. Top medical schools typically look for 3.7+, law schools weigh LSAT scores alongside GPA (3.5+ is competitive), and MBA programs at top business schools usually expect 3.5 or above. Research your specific program’s admissions statistics for the most accurate benchmark.
