How do I calculate GPA from course grades?

If you have individual course grades, use our GPA Calculator which takes credit hours and letter grades to calculate GPA directly.

Does a repeating class affect cumulative GPA?

Most schools replace the old grade with the new grade. Some schools average them. Consult your registrar's policy.

Cumulative GPA Calculator

Q: What is the difference between Semester GPA and Cumulative GPA?

Semester GPA represents grades from a single term. Cumulative GPA represents the overall average across all terms at the institution.

Q: How do transfer credits affect cumulative GPA?

Transfer credits usually count toward graduation but do not affect your GPA calculation at your new institution.

Combine multiple semesters or previous GPA with current credits to calculate your overall cumulative GPA

How to Calculate Cumulative GPA

Your cumulative Grade Point Average (GPA) represents your overall academic performance across multiple semesters. Follow these steps to calculate your overall cumulative GPA:

Enter your semester scores — Input the GPA and the total credits earned for each semester.
Add semesters as needed — Click “+ Add Semester” to add rows for additional terms.
Click “Calculate Cumulative GPA” — The tool will calculate your overall GPA, total credits earned, and total quality points.

The Formula for Cumulative GPA

To calculate cumulative GPA, you cannot simply average your semester GPAs together (unless every semester had the exact same number of credits). Instead, you must calculate the weighted average based on credit hours:

Cumulative GPA = Σ(Semester GPA × Semester Credits) ÷ Total Credits

For example, if you have:

Semester 1: 3.50 GPA with 15 credits (Quality points = 3.50 × 15 = 52.5)
Semester 2: 3.20 GPA with 16 credits (Quality points = 3.20 × 16 = 51.2)
Total Quality Points = 52.5 + 51.2 = 103.7
Total Credits = 15 + 16 = 31
Cumulative GPA = 103.7 ÷ 31 = 3.35

Why Credit Weighting Matters

If you take 12 credits in a semester and get a 4.0 GPA, then take 18 credits in the next semester and get a 3.0 GPA, your cumulative GPA is not 3.5. Because the second semester had more credits, it carries more weight in your overall GPA calculation. The actual cumulative GPA would be: ((4.0 × 12) + (3.0 × 18)) ÷ (12 + 18) = (48 + 54) ÷ 30 = 102 ÷ 30 = 3.40.

Frequently Asked Questions

What is the difference between Semester GPA and Cumulative GPA?

Semester GPA measures your grades for a single term (e.g., Fall 2025). Cumulative GPA measures your average grades across your entire academic career at the school (e.g., all semesters combined).

How do I calculate cumulative GPA if I only have course grades?

If you have grades for individual courses rather than semester GPAs, use our standard GPA Calculator, which calculates your overall GPA directly from course grades and credit hours.

Does a repeating class affect my cumulative GPA?

It depends on your school’s policy. Many schools use a “grade replacement” policy where the new grade replaces the old grade in the GPA calculation. Other schools average both grades together. Check with your academic advisor or registrar.

How do transfer credits affect cumulative GPA?

Typically, transfer credits from other institutions do not affect your cumulative GPA at your current school. The credits will transfer to count toward graduation requirements, but the grades do not affect your GPA calculation at the new school.
