Cumulative GPA Calculator

Step 1: If you already have a GPA from previous semesters, enter your current GPA (on a 4.0 scale) and total credits earned in the optional fields at the top. Leave these blank if you're starting fresh.

Step 2: Enter your courses for the current semester. For each course, type the course name, set the number of credits, and select your letter grade from the dropdown.

Step 3: Click "+ Add course" to add more courses to a semester, or "+ Add Semester" to add additional semesters.

Step 4: Click "Calculate Cumulative GPA" to see your overall GPA across all semesters, including your prior GPA if entered.

Step 5: Review the breakdown showing your per-semester GPA, total quality points, and total credits.

Cumulative GPA (Grade Point Average) is your overall academic average across all semesters and courses you've completed. Unlike a semester GPA which only covers one term, your cumulative GPA represents your entire academic record.

Colleges and employers use cumulative GPA as a quick measure of overall academic performance. It's calculated by dividing your total quality points (grade points × credits for each course) by your total credit hours attempted.

For example, if you earned a 3.5 GPA over 60 credits in your first two years, and then earned a 3.8 GPA over 15 credits in a new semester, your cumulative GPA would be (3.5 × 60 + 3.8 × 15) / (60 + 15) = (210 + 57) / 75 = 3.56.

This calculator is especially useful for students who want to see how a new semester will affect their overall GPA, or who need to determine what grades they need to reach a target cumulative GPA.

The Formula:

Cumulative GPA = Total Quality Points ÷ Total Credits

Where Quality Points for each course = Grade Points × Credit Hours

Grade Point Scale (4.0):

Example Calculation:

Prior GPA: 3.20 with 45 credits → Prior Quality Points = 3.20 × 45 = 144.0

New Semester:
- Calculus (4 cr, B+): 3.3 × 4 = 13.2
- English (3 cr, A): 4.0 × 3 = 12.0
- Physics (4 cr, B): 3.0 × 4 = 12.0

New Quality Points = 37.2, New Credits = 11

Cumulative GPA = (144.0 + 37.2) ÷ (45 + 11) = 181.2 ÷ 56 = 3.24

Example 1: First-Year Student
A freshman completed two semesters. Semester 1: English (3 cr, A), Math (4 cr, B+), History (3 cr, A-). Semester 2: Biology (4 cr, B), Chemistry (4 cr, B-), Psychology (3 cr, A). Enter all courses across two semesters — Cumulative GPA: 3.28

Example 2: Transfer Student with Prior GPA
A transfer student has a 3.40 GPA from 60 credits at their previous school. In their first semester at the new school, they take 15 credits and earn a 3.80 semester GPA. Enter 3.40 as Current GPA, 60 as Credits Earned, then add the new courses. Cumulative GPA: 3.48

Example 3: Raising a Low GPA
A student has a 2.50 GPA after 30 credits. They want to see the impact of a strong semester. They take 15 credits and earn straight A's (4.0). Enter 2.50 and 30 credits as prior, add courses with A grades. New Cumulative GPA: 3.00 — a 4.0 semester raised their GPA by 0.50 points.

Front-load easy wins. Your earliest semesters have the biggest impact on cumulative GPA because you have fewer total credits. A 4.0 in your first 15 credits moves your GPA far more than the same grades after 90 credits.

Don't ignore low-credit courses. A 1-credit lab with an F hurts your GPA just as much per credit as a 4-credit course. Every grade counts in the cumulative calculation.

Use this calculator before registration. Before signing up for a tough course load, enter your expected grades and see the impact. If a challenging semester would drop your GPA below a threshold you need (scholarships, graduate school), consider balancing it with courses where you're confident you'll do well.

Retaken courses may replace old grades. Many schools have grade replacement policies where retaking a course substitutes the new grade for the old one in your cumulative GPA. Check your school's academic catalog — this can be a powerful way to recover from a bad semester.
