How to use the GPA calculator
- For each course, choose the letter grade you received (or expect) and enter the number of credits (credit hours).
- Leave the grade as "—" for any rows you don't need.
- To find your new cumulative GPA, enter your current cumulative GPA and the total credits you have already completed.
How GPA is calculated
Your grade point average is a credit-weighted average of your grade points:
Each letter grade is converted to grade points, multiplied by the course's credits, and the total is divided by the total number of credits.
4.0 GPA scale
| Letter grade | Grade points | Typical percentage |
|---|---|---|
| A+ / A | 4.0 | 93–100% |
| A− | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B− | 2.7 | 80–82% |
| C+ | 2.3 | 77–79% |
| C | 2.0 | 73–76% |
| C− | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 63–66% |
| D− | 0.7 | 60–62% |
| F | 0.0 | Below 60% |
Some schools award 4.3 for an A+ or use different percentage cutoffs. Check your school's grading policy for exact values.
Example
Suppose you earned an A in a 4-credit course, a B+ in a 3-credit course, an A− in a 3-credit course and a C in a 2-credit course:
- A: 4.0 × 4 = 16.0 points
- B+: 3.3 × 3 = 9.9 points
- A−: 3.7 × 3 = 11.1 points
- C: 2.0 × 2 = 4.0 points
Total points = 41.0 and total credits = 12, so the semester GPA is 41.0 ÷ 12 = 3.42.
Calculating cumulative GPA
To combine semesters, multiply your previous GPA by your previous credits to get your previous grade points, add this semester's points, and divide by the total credits. For example, a 3.2 GPA over 45 credits is 144 points; adding the 41 points above gives 185 points over 57 credits — a new cumulative GPA of about 3.25.
Weighted vs. unweighted GPA
This calculator computes an unweighted GPA on a 4.0 scale. Many high schools also report a weighted GPA that adds extra points (often +0.5 or +1.0) for honors, AP or IB classes, so weighted GPAs can exceed 4.0.
Frequently asked questions
How do I calculate my GPA?
Convert each letter grade to grade points (A = 4.0, B = 3.0 and so on), multiply by the course credits, add the results, and divide by the total credits.
What is a good GPA?
On a 4.0 scale, a GPA of 3.0 (B average) is generally considered good, and 3.5 or higher is excellent. Competitive colleges and scholarships often look for 3.5 and above.
How do I calculate my cumulative GPA?
Multiply your current cumulative GPA by the credits you have completed, add the grade points from your new courses, and divide by the total credits. Enter your current GPA and credits above to do it automatically.
Does an A+ count as 4.3?
At most schools an A+ counts as 4.0, which this calculator uses. Some colleges award 4.3 for an A+; check your school's grading policy.
Do pass/fail classes affect my GPA?
Usually not. Pass/fail courses typically earn credits toward graduation but are not included in GPA calculations. Leave them out of the calculator.
