GPA Calculator
Work out your weighted grade point average on the US 4.0 scale from your courses, grades, and credit hours.
Learn how it works: How to Calculate Your GPAAdd a grade and credit hours to at least one course to see your GPA.
How to use the GPA calculator
Add one row per course. Name it if you like, choose the letter grade you earned, and type the credit hours the course was worth. Your GPA and total credits update as you fill in each row.
Use the Add course button to extend the list for a full semester or a whole transcript, and the minus button to drop a row you do not need. A course only counts once it has credit hours, so a blank row sitting at the bottom will not throw off the average.
How GPA is calculated
GPA is a weighted average, which means a five-credit course pulls harder on your number than a one-credit elective. For each course, multiply its grade points by its credit hours to get quality points. Add the quality points across every course, then divide by the total credits.
Say you earned an A worth 4.0 in a 3-credit class, a B worth 3.0 in a 4-credit class, and an A-minus worth 3.7 in another 3-credit class. The quality points come to 12, 12, and 11.1, totaling 35.1 across 10 credits. Divide and you get a 3.51 GPA.
The 4.0 grade scale
Letter grades convert to points on the standard US 4.0 scale shown below. Plus and minus modifiers shift the value by roughly a third of a point, which is why an A-minus sits at 3.7 rather than a flat 4.0.
| A+ / A | 4.0 points |
| A- | 3.7 points |
| B+ | 3.3 points |
| B | 3.0 points |
| B- | 2.7 points |
| C+ | 2.3 points |
| C | 2.0 points |
| C- | 1.7 points |
| D+ | 1.3 points |
| D | 1.0 points |
| D- | 0.7 points |
| F | 0.0 points |
Weighted and unweighted GPA
This calculator produces an unweighted GPA, where every course tops out at 4.0 regardless of difficulty. Many high schools also report a weighted GPA that adds extra points for honors, AP, or IB classes, pushing the ceiling to 5.0 in some systems.
Colleges usually recalculate applicant GPAs to their own standard, so the unweighted figure here is a reliable common baseline. If your school weights advanced courses, treat this result as your core GPA and check the official transcript for the weighted version.
Frequently asked questions
- How is GPA calculated?
- Multiply each course's grade points by its credit hours, add those products together, then divide by the total credit hours. Because heavier courses carry more credits, they count more toward the final average.
- What is a good GPA?
- A 3.0 is generally seen as solid, a 3.5 as strong, and anything above 3.7 as excellent. What counts as good depends on the program, since competitive majors and scholarships often expect higher numbers.
- Do A+ and A count the same?
- On the standard 4.0 scale, yes. Both map to 4.0 because the scale caps there. Some schools award 4.3 for an A+, but the common unweighted scale this tool uses does not, to keep results comparable.
- What is the difference between weighted and unweighted GPA?
- Unweighted GPA caps every course at 4.0. Weighted GPA adds bonus points for harder classes like AP or honors, so it can rise above 4.0. This calculator gives the unweighted figure.
- How do credit hours affect my GPA?
- Credit hours act as weights. A high grade in a 4-credit course moves your GPA more than the same grade in a 1-credit course, and a low grade in a heavy course pulls it down harder.
