Your Estimated GPA
This is an estimate based on the grade-point values selected above. Your college or university may use a different grading scale, rounding rule, or policy for certain grades. Check your institution's official grading policy or transcript instructions for an official GPA.
What Is GPA?
GPA stands for Grade Point Average. It is a numerical representation of academic performance calculated from course grades and, when applicable, the credit hours assigned to those courses.
A college GPA calculator with credits can estimate a student's GPA by giving each letter grade a numerical value, multiplying that value by the course's credit hours, adding the resulting grade points, and dividing the total grade points by the total graded credits.
How Is GPA Calculated?
A common credit-hour GPA calculation works by converting each letter grade into grade points, multiplying those points by the course credits, adding the grade points from all included courses, and dividing by the total number of graded credits.
The basic formula is:
GPA = Total Grade Points ÷ Total Credit Hours
For example, if a 3-credit course receives a B worth 3.0 grade points, that course contributes 9.0 grade points:
3.0 × 3 credits = 9.0 grade points
This credit-weighted method is documented by U.S. universities such as Arizona State University.
4.0 GPA Scale
This calculator uses a common U.S. 4.0-style grade-point scale for its default estimate.
| Letter Grade | Grade Points |
|---|---|
| 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 |
| F | 0.0 |
Grade scales are not completely standardized across every U.S. institution. Some schools assign different values to A+ or handle certain grades differently, so students should use their institution's official grading policy when an exact institutional GPA is required.
Why Do Credits Matter in GPA Calculation?
Credits matter because a credit-weighted GPA gives more weight to a course with more credits. For example, a 4-credit course has more influence on a credit-weighted GPA than a 1-credit course with the same letter grade.
To calculate course grade points, multiply the grade-point value by the number of credits:
Course Grade Points = Grade Point Value × Course Credits
GPA Calculation Example
Imagine a student has these three courses:
| Course | Grade | Credits | Grade Points |
|---|---|---|---|
| English | A | 3 | 12.00 |
| Math | B | 3 | 9.00 |
| Science | A- | 4 | 14.80 |
Total grade points = 35.80
Total credits = 10
Estimated GPA = 35.80 ÷ 10 = 3.58
Semester GPA vs. Cumulative GPA
Semester GPA
Semester GPA represents the GPA calculated from courses included in a particular academic term.
Cumulative GPA
Cumulative GPA represents GPA across the courses and credits included over multiple terms. The exact institutional rules determine which courses and grades are included.
Universities may also have separate rules for transfer credits, repeated courses, pass/fail courses, withdrawals, incomplete grades, and other transcript notations.
GPA Calculator Limitations
This GPA calculator provides an estimate using the grade-point values displayed in the calculator. It is not intended to replace an official transcript or your school's GPA calculation.
- Your school may use a different grade-point scale.
- Some schools handle A+ grades differently.
- Some courses may use pass/fail or other non-standard grading.
- Transfer credits may have separate GPA rules.
- Repeated courses may be treated differently by each institution.
- Weighted high-school GPA is different from a standard college GPA.
Frequently Asked Questions
How do I calculate my GPA?
Convert each grade into its corresponding grade-point value, multiply that value by the course credits, add all grade points, and divide by the total graded credits.
What is a 4.0 GPA?
On a common 4.0 scale, a 4.0 represents the highest standard grade point value used for an A. Exact treatment of A+ grades varies by institution.
Does GPA depend on credit hours?
A credit-weighted GPA does. Each course's grade-point value is multiplied by its credit hours before the total is divided by the total graded credits.
Can I use this as a college GPA calculator?
Yes. Enter your college courses, letter grades, and credit hours to estimate a GPA using the calculator's displayed 4.0 scale.
Can this calculate cumulative GPA?
Yes, you can enter the courses and credits you want included in the calculation. For an official cumulative GPA, follow your school's transcript and grading rules.
Is a 3.0 GPA good?
The meaning of a GPA depends on the school, program, academic requirements, scholarships, and other context. Use your institution's published requirements when evaluating a specific GPA.
Do all U.S. colleges use the same GPA scale?
No. Many institutions use a 4-point system, but grade values, A+ treatment, rounding, repeated courses, and other policies can differ between institutions.
