How to use the semester gpa calculator
- Enter each course on a new line using the format name, grade, credits (for example:
Biology 101, A, 4). - Choose between the Plus/Minus or Standard grading scale from the dropdown.
- Review the calculated semester GPA and total attempted credits at the top of the results.
- Check the per-course table below to see how many quality points each class contributed to your term GPA.
How semester GPA is calculated
A semester GPA is the weighted average of your grade points, where each course weight is its credit hours. The formula is:
Semester GPA = Total Quality Points / Total Credit Hours
Quality points for a single course equal the numeric grade value multiplied by the credit hours. For example, if you earn an A- (3.7) in a 4-credit course, that class contributes 3.7 x 4 = 14.8 quality points. If you also earn a B+ (3.3) in a 3-credit course, that adds 3.3 x 3 = 9.9 points. Your total is 24.7 quality points across 7 credits, giving a semester GPA of 24.7 / 7 = 3.53.
This term GPA calculation treats every course proportionally: a 4-credit lab affects your average more than a 1-credit seminar.
The result is rounded to two decimals with exact ties rounded up, so a true 3.675 shows as 3.68.
Plus/minus versus standard grading scales
The grading scale you select determines the numeric value assigned to each letter grade. The two most common systems are:
| Letter grade | Plus/Minus value | Standard value |
|---|---|---|
| A+ | 4.0 | 4 |
| A | 4.0 | 4 |
| A- | 3.7 | 4 |
| B+ | 3.3 | 3 |
| B | 3.0 | 3 |
| B- | 2.7 | 3 |
| C+ | 2.3 | 2 |
| C | 2.0 | 2 |
| C- | 1.7 | 2 |
| D+ | 1.3 | 1 |
| D | 1.0 | 1 |
| D- | 0.7 | 1 |
| F | 0.0 | 0 |
Under the standard scale, an A- counts the same as an A (both are 4.0). Under the plus/minus scale, an A- drops to 3.7. Always check which system your institution uses before calculating your semester GPA, because the difference can shift your average by several tenths of a point.
Common input mistakes to avoid
When using any term GPA calculator, small data-entry errors produce misleading results. Watch for these issues:
- Wrong delimiter. Each line must separate the course name, grade and credits with a comma or tab. Semicolons or spaces alone will cause parsing failures.
- Missing credits. Every course needs a numeric credit value. Zero-credit courses (audits, pass/fail seminars) do not factor into the GPA and should be excluded. If every course has zero credits, the tool shows an error instead of a GPA, because there is nothing to average.
- Invalid grades. Only standard letter grades (A through F, with optional + or -) are accepted. Symbols like P, S, U, W or I are not included in GPA math and should be left out.
- Mixing scales. Do not enter A- grades while using the standard scale if your school does not distinguish them. The tool will treat A- as A under the standard setting, but verify this matches your transcript.
What counts as a good semester GPA
Many universities set Dean's List or honor roll thresholds around a 3.5 semester GPA, though this varies widely by institution, college and enrollment status. Some schools require a 3.7 or higher, while others use a 3.0 cutoff for graduate students. Graduate programs often expect you to maintain at least a 3.0 each term to remain in good standing.
If you need to understand how your term average fits into your broader academic record, you can combine it with previous terms using a cumulative GPA calculator. Students who want to see what future grades are needed to reach a target average may find a GPA raise calculator helpful. For institutions that add extra points for honors or AP classes, a weighted GPA calculator handles that adjustment.
Semester GPA versus cumulative GPA
Your semester GPA reflects only the courses taken in a single term. Your cumulative GPA averages all graded coursework across every completed term. Both use the same quality-points formula, but the cumulative version sums all historical quality points and divides by all historical credits.
A strong semester GPA can significantly improve a lower cumulative average, especially early in your academic career when total attempted credits are still small. Conversely, a poor term has less impact on your cumulative record once you have accumulated many credits. Use this semester gpa calculator each term to track your progress before updating your overall record.

FAQ
How do I calculate my semester GPA?
Multiply the numeric grade value of each course by its credit hours to get quality points. Sum all quality points and divide by the total credit hours attempted that term.
Does an A+ count as more than 4.0?
On most US 4.0 scales, an A+ is capped at 4.0, the same as a regular A. Some institutions award 4.3 for an A+, so check your school's specific policy before entering grades.
Do pass/fail courses affect my semester GPA?
No. Pass/fail, audit and withdrawal grades typically carry no quality points and are excluded from the GPA calculation. Only include courses that received a standard letter grade.
What is the difference between plus/minus and standard scales?
The standard scale assigns whole numbers (A=4, B=3, C=2, D=1, F=0). The plus/minus scale adds intermediate values (A-=3.7, B+=3.3, etc.), making the GPA more sensitive to slight grade differences.
Can I use this term GPA calculator for graduate courses?
Yes, as long as your program uses a standard 4.0 letter-grade scale. Enter your graduate course grades and credits exactly as you would for undergraduate classes.
