What is GPA?
GPA stands for grade point average. It turns the letter grades you earn into one number, usually on a 4.0 scale, so schools, scholarship committees and employers can compare students quickly. Each letter has a point value (an A is 4.0, a B is 3.0 and so on), and courses with more credit hours count for more.
You will see two main versions: your semester GPA, which covers one term, and your cumulative GPA, which covers everything you have taken so far.
How to calculate GPA step by step
- Convert each letter grade to grade points.
- Multiply the grade points by the course's credit hours to get quality points.
- Add up all quality points.
- Divide by the total credit hours.
Courses with more credits move your GPA more. A bad grade in a 4-credit class hurts more than the same grade in a 1-credit class.
Unweighted vs weighted GPA
An unweighted GPA treats every class the same: an A is 4.0 whether it is gym or physics. A weighted GPA gives extra points for harder classes. A common system adds 0.5 for honors and 1.0 for AP or IB, which is why a weighted GPA can go above 4.0.
Weighting rules differ between schools, and the bonus normally applies only to passing grades. This calculator uses the common +0.5 and +1.0 system and does not add a bonus to an F. Check your school's policy for the exact rule it uses on your transcript.
GPA scale chart
| Letter | Grade points | Typical percentage |
|---|---|---|
| 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+ / D / D- | 1.3 / 1.0 / 0.7 | 60-69% |
| F | 0.0 | below 60% |
The percentage ranges are common ones. Each school sets its own cut-offs, and some schools treat A+ as 4.3, so use your school's chart if it has one.
What is a good GPA?
It depends on what you are aiming for. A 3.0 is a B average, which meets the minimum for many scholarships and transfer programs. A 3.5 or higher usually qualifies for dean's list or honor roll at many schools. Competitive programs often expect more, so check the requirement of the specific school, scholarship or employer.
Remember that a GPA is one part of an application. Course difficulty, trend over time and the rest of your record also matter.
How to raise your GPA
- Focus on high-credit courses. They have the biggest effect on the average.
- Use the goal planner above to see what grade average you need over your remaining credits. It shows the exact number instead of a guess.
- Ask about grade replacement. Some schools replace or average a retaken course. Policies differ, so confirm with your advisor.
- Raise the early grades. The more credits you have, the slower the average moves, so improving sooner helps most.
Cumulative GPA and goal planning
Your cumulative GPA combines all terms. To find the grades you need, the calculator solves for the average that makes your target true:
Needed GPA = (target ร (credits so far + remaining credits) โ quality points so far) รท remaining credits.
If the answer is above 4.0, the target cannot be reached with the credits you have left. If it is zero or less, you can already keep that GPA.
