How a GPA Calculator Works
Your grade point average (GPA) is a single number that summarises your academic performance across many courses. It is a credit-weighted average of your grades: courses worth more credit hours count more toward the final figure. The calculation has three steps, and the tool above runs them every time you change an input.
First, each letter grade is converted to a grade-point value on the 4.0 scale — an A is 4.0, a B is 3.0, a C is 2.0, and so on, with pluses and minuses landing in between. Second, each grade-point value is multiplied by the course's credit hours to produce quality points. Third, all the quality points are added together and divided by the total number of credit hours.
GPA = Σ ( grade points × credit hours ) ÷ Σ ( credit hours )
Because the denominator is total credits, two students with the same letter grades can end up with different GPAs if their courses carry different credit weights. That is intentional: it means a strong performance in a demanding, high-credit course is recognised more than the same grade in a one-credit elective.
Worked example
Suppose you took three courses this term:
- Calculus — grade A (4.0), 4 credits → 16.0 quality points
- English — grade B+ (3.3), 3 credits → 9.9 quality points
- History — grade A- (3.7), 3 credits → 11.1 quality points
Total quality points = 16.0 + 9.9 + 11.1 = 37.0. Total credits = 4 + 3 + 3 = 10. GPA = 37.0 ÷ 10 = 3.70.
4.0 Grading Scale
This calculator uses the standard United States 4.0 scale, where an A+ is capped at 4.0. The percentage column shows the typical range each letter represents, though exact cut-offs vary by school.
| Letter | Grade points | Percentage |
|---|---|---|
| A+ | 4.0 | 97–100% |
| A | 4.0 | 93–96% |
| 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 | 60–66% |
| F | 0.0 | Below 60% |
Frequently Asked Questions
What is a good GPA?
On the standard 4.0 scale, a GPA of 3.5 or higher is generally considered strong, 3.0 is solid, and 2.0 is the usual minimum to stay in good academic standing. Context matters: competitive university programs and scholarships often look for 3.7+, while many employers simply want to see a 3.0 or that you graduated in good standing. Rather than chasing one universal number, compare your GPA to the requirement that matters for your goal — admission cut-offs, honors thresholds, or financial-aid rules — and aim to clear that bar.
How do I calculate my GPA by hand?
Convert each letter grade to its grade-point value (A = 4.0, B = 3.0, and so on), multiply each value by the number of credit hours for that course to get quality points, add up all the quality points, then divide by the total number of credit hours. For example, an A (4.0) in a 4-credit class and a B (3.0) in a 3-credit class give 16 + 9 = 25 quality points across 7 credits, for a GPA of 3.57. The calculator above does exactly this in real time so you never have to reach for a spreadsheet.
What is the difference between weighted and unweighted GPA?
An unweighted GPA treats every course the same and caps at 4.0. A weighted GPA gives extra points for harder classes — typically +0.5 for Honors and +1.0 for AP or IB — so it can rise above 4.0. Unweighted GPA answers "how well did you do?", while weighted GPA also rewards "how challenging was your schedule?". Many high schools report both numbers. Use this page for unweighted GPA and the weighted GPA calculator when your courses carry Honors or AP credit.
Do credit hours affect my GPA?
Yes. GPA is a credit-weighted average, so a grade in a 4-credit course influences your GPA more than the same grade in a 1-credit course. That is why a strong grade in a heavy lecture class can lift your GPA more than an equal grade in a short lab or seminar. When you enter accurate credit hours for each course, the calculator weights them automatically. If you leave every course at the same credit value, the result is simply the straight average of your grade points.
Is an A+ worth 4.0 or 4.3?
It depends on your institution. The most common convention — and the default used here — caps an A+ at 4.0, the same as an A, so no single course can exceed a perfect grade point. Some colleges, however, award 4.3 for an A+, which lets a GPA climb slightly above 4.0. Check your school's official grading policy or transcript legend to confirm. If your school uses 4.3, your true GPA may be marginally higher than the figure shown here for transcripts full of A+ grades.
How can I raise my GPA?
Focus your effort where it moves the needle most: higher-credit courses and grades that are close to the next letter boundary. Because GPA is credit-weighted, pulling a 3-credit class from a B to an A raises your average more than nudging a 1-credit class. Retaking a low course where your school allows grade replacement, choosing a balanced course load, and using office hours early all help. Use the cumulative GPA calculator to model "what if" scenarios before the term even starts.
