High School GPA Calculator
Use this Calculator to estimate your GPA using your grades, credits, and course level. You can check your weighted, unweighted, semester, or target GPA in a simple way.
Enter Your Classes
Use letter grades, percentages, or GPA points in the grade field.
Scale and weight settings
Enter Your Classes and Grades
Start by adding each course or subject you want to include. You can enter a letter grade, percentage grade, or direct GPA point value.
This makes the tool useful whether your school reports grades as letters, percentages, or GPA points. You can also add credits, so classes with more credit hours are counted correctly.
For the best result, use the same grades shown on your school transcript or high school transcript. If your school uses a different grading scale, your official GPA may be slightly different.
How Your GPA Is Calculated
Your Grade Point Average is based on grade points and total credits. Each class grade is converted into a grade value, then multiplied by the class credit.
The basic formula is:
GPA = Total grade points ÷ Total credits
For example, a class with more credit hours can affect your GPA more than a smaller class. That is why a 1-credit class and a 0.5-credit class may not have the same impact on your overall result.
Weighted vs Unweighted GPA
An unweighted GPA usually uses a standard 4.0 GPA scale. On this scale, common grade values are:
| Letter Grade | GPA Points |
|---|---|
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
A weighted GPA can be higher because some schools give bonus points for harder classes. This is common for Honors, AP, IB, and Dual Enrollment courses.
Use the weighted option if your school gives extra points for advanced classes. Use the regular grade value if you want an unweighted GPA.
Course Levels and Bonus Points
Many schools give extra weight for advanced classes because of course difficulty and course rigor. This calculator can include bonus points for Honors, AP, IB, or college-level courses.
| Course Level | Common GPA Weight |
|---|---|
| Regular Classes | No extra weight |
| Honors Classes | Extra honors bonus |
| AP Classes / Advanced Placement | Extra AP bonus |
| IB Classes / International Baccalaureate | Extra IB bonus |
| Dual Enrollment | Possible college course bonus |
A weighted scale may go up to a 5.0 GPA scale, while an unweighted scale usually stays between 0.0 and 4.0.
GPA Scale and Grade Conversion
Your school may use its own letter grade conversion or percentage grade conversion. The table below is a common example only.
| Percentage Grade | Letter Grade | Common GPA Points |
|---|---|---|
| 90–100 | A+, A, A- | Around 4.0 |
| 80–89 | B+, B, B- | Around 3.0 |
| 70–79 | C+, C, C- | Around 2.0 |
| 60–69 | D+, D, D- | Around 1.0 |
| Below 60 | F | 0.0 |
Some schools use different grade cutoffs, grade ranges, or percentage ranges. Always compare your result with your school’s official GPA chart or grade conversion chart.
Semester and Cumulative GPA
You can use this tool as a semester GPA calculator when you only want to check one term. Add the classes from that semester, and the result will show your estimated semester GPA.
You can also use it as a cumulative GPA calculator by including past and current classes together. To estimate cumulative GPA, add your completed credits, current grades, and previous academic record if available.
Your cumulative GPA is helpful for tracking academic performance, academic standing, graduation progress, scholarship eligibility, and college admissions planning.
Target GPA Planning
This option helps you estimate what average you may need in upcoming credits to reach your desired GPA.
This is useful when you want to plan before your next semester grades are final.
A simple estimate looks at:
- your current GPA
- your completed credits
- your upcoming credits
- your desired GPA
- the required GPA needed in future classes
The result is only an estimate, but it can help you plan your course load and understand your projected GPA.
How to Read Your Result
After you add your class grades, the calculator shows your estimated weighted average, total points, total credits, and GPA range.
Your result may include:
- Weighted GPA
- Unweighted GPA
- Cumulative GPA
- Semester GPA
- Target GPA
- Credits
- Credit Hours
- Classes counted
If your weighted GPA is above 4.0, that usually means your school gives extra value for harder classes. Some schools cap results at 0.0 to 5.0 GPA or use their own 5.0 Scale.
Why Your School GPA May Be Different
Your official GPA can be different from this estimate because every school may use its own GPA scale, grade distribution, and school profile.
Some schools count all classes. Others focus more on college-preparatory courses, math, science, English, social studies, world language, or selected electives.
For official advice, check with your school counselor or admissions office.
GPA and College Admissions
Your GPA is one part of your college application. Colleges may also review course difficulty, class rank, Honors classes, Advanced Placement, International Baccalaureate, Dual Enrollment, and your full transcript.
A strong GPA can support college readiness, but colleges may review weighted and unweighted results differently. Some schools also recalculate GPA using their own admission method.

FAQs
What is a GPA?
A GPA is your Grade Point Average. It shows your average performance across your courses, usually on a 4.0 scale or a weighted scale.
How do I calculate my GPA?
Enter your course grades, select the grade scale, add your class credits, and divide your total grade points by your total credits.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses the normal 4.0 GPA scale. A weighted GPA can add extra points for harder classes like AP, IB, Honors, or Dual Enrollment.
Can my weighted GPA be higher than 4.0?
Yes. A weighted GPA can be higher than 4.0 if your school gives bonus points for advanced classes. Some schools use a 5.0 scale or cap the result at 5.0.
How do credits affect GPA?
Credits show how much weight a class has. A class with more credit hours affects your GPA more than a class with fewer credits.
Can I use percentages instead of letter grades?
Yes. You can enter percentage grades, and the calculator can estimate the matching GPA point based on the selected scale.
Can I calculate GPA from letter grades?
Yes. Add grades like A, B, C, D, or F, and the calculator will convert them into GPA points.
What is a good GPA?
A good GPA depends on your school, classes, and goals. For college planning, compare your result with your target colleges, school profile, and advice from your school counselor.
Do colleges use weighted or unweighted GPA?
Some colleges review weighted GPA, some review unweighted GPA, and some recalculate GPA using their own method. Your transcript, course rigor, and admission requirements all matter.
Why is my GPA different from my transcript?
Your transcript may use a custom grade scale, different grade cutoff rules, or special rules for regular, Honors, AP, and IB courses. Use this calculator as an estimate, not as an official transcript replacement.
