How GPA is Calculated

Your GPA is calculated by:

  1. Converting each letter grade to grade points (e.g., A = 4.0, B = 3.0)
  2. Multiplying each course's grade points by its credit hours
  3. Adding up all the grade points
  4. Dividing by the total number of credit hours

Formula: GPA = (Sum of Grade Points × Credit Hours) / Total Credit Hours

Frequently Asked Questions

How do I calculate my GPA?

To calculate GPA: (1) Convert each letter grade to points (A=4.0, B=3.0, etc.), (2) Multiply by credit hours, (3) Add all grade points together, (4) Divide by total credit hours. Use the calculator above for instant results.

What is a good GPA?

Generally, a GPA above 3.0 is considered good, 3.5+ is very good, and 3.7+ is excellent. However, this varies by institution and field of study. For competitive graduate programs, a GPA of 3.5 or higher is often expected.

What GPA do I need for grad school?

Most competitive graduate programs require a minimum GPA of 3.0, with top programs preferring 3.5 or higher. Requirements vary by field - STEM programs may be more flexible, while law and medical schools are very selective.

What's the difference between 4.0 and 5.0 scale?

On a 4.0 scale, the highest grade (A or A+) is worth 4.0 points. On a 5.0 scale, an A+ is worth 5.0 points, while an A is worth 4.0 points. Always check which scale your institution uses.

How do I convert percentage to GPA?

First, convert your percentage to a letter grade based on your institution's grading scale, then use the corresponding grade point value. Most institutions use: 90-100% = A (4.0), 80-89% = B (3.0), 70-79% = C (2.0), 60-69% = D (1.0), below 60% = F (0.0). If you're a UK student, see our degree classification calculator to convert your UK percentage to degree class.

Do all credits count equally?

No, courses with more credit hours have a larger impact on your GPA. A 4-credit course affects your GPA more than a 2-credit course, which is why credit hours are factored into the calculation.

Can I calculate my cumulative GPA for multiple semesters?

Yes! Simply enter all courses from all semesters into the calculator. The result will be your overall cumulative GPA.
