What Is GPA?
GPA stands for Grade Point Average. It is a numerical representation of your academic performance based on the grades you earn in your courses. Schools and colleges commonly use GPA to summarize performance across multiple classes instead of listing every individual grade.
On a standard unweighted 4.0 scale, an A is commonly represented by 4.0 grade points, while lower letter grades receive fewer points. Your GPA is not normally calculated by simply adding your grades and dividing by the number of classes. Courses with different credit values can have different effects on the final result.
This GPA calculator uses course credits when calculating the average. That means a four-credit course has more influence on the result than a one-credit course. This is useful for calculating a semester GPA or estimating a cumulative GPA when you have course grades and credit hours available.
How to Calculate GPA
The basic formula for a credit-weighted GPA is straightforward:
Quality points are calculated by multiplying the grade point value of a course by the number of credits for that course.
Example
Suppose you receive an A worth 4.0 points in a 3-credit course. That course gives you 12 quality points because 4.0 × 3 = 12. If you receive a B worth 3.0 points in another 3-credit course, that course contributes 9 quality points.
Together, you have 21 quality points over 6 credits. Your GPA would therefore be 21 ÷ 6 = 3.50.
- Convert each letter grade into its corresponding grade point value.
- Multiply each grade point value by the credits for that course.
- Add the quality points from all completed courses.
- Add the credits from all included courses.
- Divide total quality points by total credits.
How to Use the GPA Calculator
You can use this calculator for a single semester, several semesters, or a larger collection of courses. The calculation is performed directly in your browser as you enter your information.
1. Add Your Courses
Enter a course name if you want to identify each class. Course names are optional and do not affect the calculation.
2. Select Your Grade
Choose the letter grade you received from the available 4.0 scale options, including A, A-, B+, B, B-, and other standard grades.
3. Enter Course Credits
Enter the number of credits or credit hours assigned to the course. Courses with more credits have a greater effect on a credit-weighted GPA.
4. Review Your Result
Your GPA, total credits, and total quality points update automatically whenever you change a grade, credit value, or add another course.
Standard 4.0 GPA Scale
The following table shows the grade point values used by this calculator. Percentage ranges are included as general examples only because grading policies vary between schools, colleges, universities, and individual courses.
| Letter Grade | Grade Points | Typical Percentage Range |
|---|---|---|
| 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+ | 1.3 | 67–69% |
| D | 1.0 | 63–66% |
| D- | 0.7 | 60–62% |
| F | 0.0 | Below 60% |
These percentage ranges are examples rather than universal rules. Your school may use different percentage boundaries for A, B, C, and other letter grades. When your transcript already provides a GPA or grade point value, use the institution's stated scale instead of assuming that a particular percentage corresponds to a specific GPA.
Weighted vs. Unweighted GPA
An unweighted GPA generally uses a maximum of 4.0 grade points for an A. This is the type of scale used by this calculator. Every course is evaluated using the same basic grade point scale, while the number of course credits determines how strongly that course contributes to the overall average.
A weighted GPA can use additional grade points for more advanced courses. For example, a school may assign extra value to honors, Advanced Placement, International Baccalaureate, or other advanced classes. Because schools use different weighting systems, a weighted GPA cannot be calculated reliably without knowing the exact policy used by the institution.
If your transcript reports a weighted GPA, use the grading rules supplied by your school rather than applying a generic weighted scale. This calculator is intended for the standard unweighted 4.0 system.
How to Calculate Cumulative GPA
Cumulative GPA represents academic performance across multiple terms or semesters. You can calculate it by including the courses you want to evaluate from all applicable semesters in the calculator.
For example, if you completed courses during your first, second, and third semesters, you can enter those courses together. The calculator combines their quality points and credits before calculating the overall GPA.
This approach is especially useful when each semester contains courses with different credit values. Simply averaging individual semester GPAs can produce a different result from calculating GPA using all course credits together. When available, your official transcript should remain the primary source for your institutional cumulative GPA.
Semester GPA vs. Cumulative GPA
A semester GPA measures your performance during one academic term. A cumulative GPA combines eligible coursework across multiple terms. Both values use similar concepts, but they cover different groups of courses.
To calculate a semester GPA, enter only the courses from that semester. To estimate a cumulative GPA, enter the relevant courses from all semesters included in your calculation. If your institution excludes certain courses, uses grade replacement, applies special weighting, or treats repeated courses differently, follow its official calculation rules.
Why Credits Matter in GPA Calculations
Credits determine how much each course contributes to a credit-weighted GPA. A grade in a three-credit course contributes three times as many quality-point units as the same grade in a one-credit course.
Consider two courses where you earn an A. If one course is worth four credits and the other is worth one credit, the four-credit course contributes 16 quality points while the one-credit course contributes 4 quality points.
This is why entering the correct credit value for every course is important. If your school uses credit hours, semester hours, or another academic unit, use the value that your institution uses for GPA calculations.
Can You Convert a Percentage to GPA?
A percentage does not have one universal GPA equivalent. Schools can use different grading boundaries, grading policies, and GPA scales. For example, the percentage required for an A may differ between institutions.
If you have a percentage and need to determine the corresponding letter grade, check your school's grading scale first. You can then enter the corresponding letter grade into this GPA calculator. For additional percentage calculations, you can also use NovaBuildr's Percentage Calculator .
Common GPA Calculation Mistakes
- Ignoring course credits: Averaging letter-grade values without considering credit hours can produce an incorrect result when courses have different credit values.
- Using the wrong grading scale: Not every school uses the same percentage boundaries or grade point values.
- Mixing weighted and unweighted grades: Advanced-course weighting can change the calculation, so you should not combine different grading systems without understanding the institution's rules.
- Including courses that should be excluded: Some schools treat pass/fail courses, repeated classes, withdrawals, or transfer credits differently.
- Rounding too early: Keeping the underlying values until the final calculation can help avoid small rounding differences.
Tips for Managing Your GPA
- Keep a record of your grades and credit hours after each term.
- Check your institution's official grading and GPA policy before comparing your GPA with another school.
- Pay attention to higher-credit courses because they have more influence on a credit-weighted GPA.
- When repeating a course, check whether your institution replaces the previous grade or includes both attempts.
- Use your transcript as the official source when an exact institutional GPA is required for applications, scholarships, or academic records.

Frequently Asked Questions About GPA
How is GPA calculated?
GPA is calculated by dividing total quality points by total credits. Quality points for each course are found by multiplying the course's grade point value by its credit value.
What is a 4.0 GPA?
A 4.0 GPA is the maximum value on the standard unweighted 4.0 scale used by many schools. It generally represents an A-level average, although exact grading policies vary between institutions.
What is the difference between weighted and unweighted GPA?
An unweighted GPA generally uses the standard 4.0 scale. A weighted GPA can assign additional points to advanced courses. The exact weighted system depends on the school.
Can I calculate my cumulative GPA?
Yes. Enter the courses you want to include from multiple semesters. The calculator combines their quality points and credits to calculate the credit-weighted GPA.
Does this calculator support weighted GPA?
This calculator uses a standard unweighted 4.0 scale. Weighted GPA systems differ between schools, so the correct calculation depends on your institution's grading policy.
Can I use this for a semester GPA?
Yes. Enter only the courses from the semester you want to calculate. The result will represent the credit-weighted GPA for those courses.
Why does a higher-credit course affect GPA more?
GPA calculations use course credits as weights. A course with more credits contributes more quality points and therefore has a greater effect on the final average.
