What GPA is and how to calculate it
GPA stands for grade point average. It is a number between 0.0 and 4.0 that summarizes your grades as a single score. Schools use it to measure academic performance, and colleges and employers sometimes look at it when making decisions.
To calculate your GPA, you convert each letter grade to a number, multiply that number by the credit hours for the class, add all those products together, then divide by the total credit hours. The result is your GPA. Most schools use the standard scale where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0, though some schools add plus and minus grades that shift the value by 0.3 points.
Your GPA is not the same as your class grade. A class grade is what you earned in one course. Your GPA is the weighted average of all your class grades combined.
Key Takeaways
- Convert each letter grade to its point value using your school's grading scale, which is usually A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0.
- Multiply each grade's point value by the number of credit hours for that class to find the grade points earned in that course.
- Add all the grade points together, then divide by the total number of credit hours across all classes to get your GPA.
- Your school's registrar or student portal usually displays your GPA automatically, so you can verify your calculation against their records.
Understanding your school's grading scale
Before you calculate, you need to know what number your school assigns to each letter grade. The standard scale is A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0. However, many schools add plus and minus grades. An A− might be 3.7, an A+ might be 4.0 (or sometimes capped at 4.0 even if the scale goes higher), a B+ might be 3.3, and a B− might be 2.7.
Some schools use a different scale altogether. A few high schools and colleges use a weighted scale where honors or AP classes are worth more—an A in an AP class might count as 5.0 instead of 4.0. Check your school's website, student handbook, or ask your registrar what scale applies to your grades. Do not assume; the difference between a 3.7 and a 4.0 matters when schools are comparing students.
The step-by-step calculation
Here is the process in order:
- List every class you took in the term or year you are calculating for, along with the letter grade you received and the credit hours for that class.
- Convert each letter grade to its point value using your school's scale.
- Multiply the point value by the credit hours for that class. This gives you the grade points for that class.
- Add all the grade points together to get your total grade points.
- Add all the credit hours together to get your total credit hours.
- Divide total grade points by total credit hours. The result is your GPA, rounded to two decimal places.
Here is a concrete example. Say you took four classes:
| Class | Grade | Point Value | Credit Hours | Grade Points |
|---|---|---|---|---|
| English 101 | A | 4.0 | 3 | 12.0 |
| Biology 201 | B+ | 3.3 | 4 | 13.2 |
| History 150 | B | 3.0 | 3 | 9.0 |
| Spanish 102 | A− | 3.7 | 3 | 11.1 |
Total grade points: 12.0 + 13.2 + 9.0 + 11.1 = 45.3. Total credit hours: 3 + 4 + 3 + 3 = 13. GPA: 45.3 ÷ 13 = 3.48.
Cumulative GPA versus term GPA
Term GPA is your average for one semester or quarter only. Cumulative GPA is your average across all terms you have completed at a school. The calculation method is the same, but cumulative GPA includes every class from every term, while term GPA includes only classes from that one term.
Most schools report both numbers. Your cumulative GPA is what appears on your transcript and what colleges or employers see. Your term GPA helps you track whether you are improving or declining semester to semester. If you retake a class, the rules for how it affects your GPA vary by school—some schools count both grades, some count only the new grade, and some average them. Ask your registrar how retakes are handled at your school.
Where to find your GPA
You do not have to calculate your GPA by hand. Your school maintains it automatically. Log into your student portal or learning management system—most schools call this Blackboard, Canvas, Brightspace, or D2L, though the name varies. Look for a section labeled "Grades," "Academic Record," "Transcript," or "GPA." Your cumulative GPA and current term GPA should both be visible there.
If you cannot find it online, email your registrar or visit the registrar's office in person. They can print your official transcript, which includes your GPA. Keep in mind that your portal GPA updates after grades are posted, which usually happens a few days after the end of the term. If you are checking mid-semester, the number you see is not final.
Why your GPA matters and when it does not
GPA is used for several purposes. Colleges look at high school GPA during admissions. Graduate schools look at undergraduate GPA. Some employers ask for GPA on job applications, especially for entry-level positions or internships. Scholarships often have GPA requirements to keep the money. Academic standing—whether you are in good standing, on probation, or at risk of dismissal—is usually based on GPA.
However, GPA is not everything. A single number cannot capture what you learned, how hard you worked, or what you are capable of doing. Many employers care more about skills, experience, and what you can do than about your GPA. If your GPA is lower than you want, focus on improving it going forward, but do not assume it closes all doors. Different schools and employers weight GPA differently, and many do not require it at all.
Frequently Asked Questions
Does an F grade hurt my GPA forever?
An F counts as 0.0 grade points and pulls your GPA down. However, if you retake the class and earn a better grade, your school may replace the F with the new grade when calculating your GPA, or it may average the two grades. The policy depends on your school. Ask your registrar whether retakes replace or average the original grade.
What if I took a class pass/fail instead of for a letter grade?
Pass/fail classes usually do not count toward your GPA at all. A "pass" does not add grade points, and a "fail" does not subtract them. The credit hours may or may not count toward your total credit hours depending on your school's rules. Check your student handbook or ask your registrar.
Can I calculate my GPA if I do not know the credit hours for each class?
Most classes are worth 3 or 4 credit hours, but you should not guess. Credit hours are listed in your course schedule, on your transcript, or in your school's course catalog. If you cannot find them, email your registrar with your class names and semester, and they will provide the information.
How do weighted classes like AP or honors affect my GPA?
Some schools give extra weight to AP, honors, or advanced classes by assigning them a higher point value—for example, an A in an AP class might be worth 5.0 instead of 4.0. Other schools do not weight classes at all. Check your school's grading scale or ask your registrar whether weighted classes explore to you.
What is a good GPA?
A 3.0 GPA is a B average, and a 3.5 GPA is between an A− and an A average. What counts as "good" depends on the context. For college admissions, a 3.5 or higher is competitive at most schools. For graduate school, standards are often higher. For jobs, many employers do not ask for GPA at all. If you are aiming for a specific school or program, look up their average admitted GPA.
