Cumulative GPA Calculator
Enter your current cumulative GPA and the credits behind it, then add this term's courses with letter grades or grade points. You get your new cumulative GPA, this term's GPA and how much your GPA moved, plus the GPA you need in future credits to hit a target.
Last updated:
1. Your current record
Use the GPA hours (graded credits) from your transcript. Leave both empty if this is your first term.
2. New courses this term
Retake? Pick the grade you are replacing and the old attempt is removed from your record (grade replacement policy). P and W grades are not counted in GPA.
3. Plan ahead: what GPA do I need?
How to use the Cumulative GPA Calculator
- Enter your current cumulative GPA and the credits it is based on (from your transcript or student portal).
- Add this term's courses with credits and a letter grade, or switch to grade points.
- Mark retakes by choosing the old grade being replaced, if your school replaces retaken grades.
- Read your new cumulative GPA, term GPA and the change.
- Use the planner to see what GPA you need over future credits to reach a target.
The cumulative GPA formula
Cumulative GPA = (current GPA × current credits + Σ new grade points × credits) ÷ (current credits + new credits)
| Step | Example | Result |
|---|---|---|
| Existing quality points | 3.20 GPA × 45 credits | 144.0 points |
| Calculus II, 4 credits, B+ | 3.3 × 4 | 13.2 |
| English Composition, 3 credits, A | 4.0 × 3 | 12.0 |
| Biology Lab, 1 credit, A− | 3.7 × 1 | 3.7 |
| New term total | 8 credits | 28.9 points → term GPA 3.61 |
| Cumulative GPA | (144.0 + 28.9) ÷ (45 + 8) | 172.9 ÷ 53 = 3.26 |
Letter grade to grade points (4.0 scale)
| Grade | A+ / A | A− | B+ | B | B− | C+ | C | C− | D+ | D | D− | F |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Points | 4.0 | 3.7 | 3.3 | 3.0 | 2.7 | 2.3 | 2.0 | 1.7 | 1.3 | 1.0 | 0.7 | 0.0 |
This is the most common US college scale. Some schools give A+ 4.33 (tick the option), and some do not use D− or plus/minus grades at all; switch to grade points if your scale differs.
Tips for raising a cumulative GPA
- Early terms matter most. Every credit you add dilutes the effect of the next one, so a strong first year is far easier than a late recovery.
- Retake strategically. If your school replaces retaken grades, retaking a 4-credit F with a B adds 12 quality points without adding credits, often more impact than a new A.
- Heavier courses count more. A grade in a 4- or 5-credit course moves your GPA more than one in a 1-credit lab.
- Know the thresholds. Scholarships, honors and academic probation usually depend on cumulative GPA at specific cut-offs such as 2.0, 3.0 or 3.5. Use the planner to see how many credits it takes to cross one.
Frequently asked questions
How is cumulative GPA calculated?
Cumulative GPA is total quality points divided by total GPA credits. Quality points for a course are its grade points times its credits. Your existing quality points are your current GPA times your completed credits. For example, a 3.20 GPA over 45 credits is 144 points; adding 11 credits worth 37.3 points gives 181.3 ÷ 56 = 3.24.
Why can't I just average my semester GPAs?
Because semesters have different numbers of credits. A 4.0 in a 6-credit summer term should not count as much as a 3.0 in an 18-credit semester. Weighting by credits, as this calculator does, gives the same result your registrar calculates.
How do retakes affect my cumulative GPA?
Under a grade-replacement policy, the new grade replaces the old one: the old attempt's credits and quality points are removed and the new ones added. Some schools instead average both attempts or keep both on the record. If your school counts both, leave the 'Retake of' column empty.
Do pass/fail and withdrawn courses count?
Usually not. A P (pass) earns credit toward graduation but no grade points, and a W does not count at all, so neither changes your GPA. A failing grade in a pass/fail course may count as an F at some schools; check your catalog.
How much can one semester raise my GPA?
The more credits you already have, the less one term can move it. With 30 credits at 3.0, a 4.0 term of 15 credits raises you to 3.33; with 90 credits at 3.0, the same term only reaches 3.14. The planner shows the exact GPA you need for any target.
Which credits should I enter as completed?
Use the GPA credits (also called GPA hours or quality hours) from your transcript, not total earned credits. Transfer credits and pass/fail credits usually count toward graduation but not toward your GPA.
