How GPA is calculated
Your grade point average (GPA) is a credit-weighted average of your grades. Every letter grade is worth a number of grade points, and courses with more credit hours count for more.
GPA = Σ (grade points × credits) ÷ Σ credits
The top part, grade points multiplied by credits, is called quality points. Your transcript may list them.
Worked example
| Course | Grade | Points | Credits | Quality points |
|---|---|---|---|---|
| Calculus I | A | 4.0 | 4 | 16.0 |
| English Composition | B+ | 3.3 | 3 | 9.9 |
| Chemistry | B | 3.0 | 4 | 12.0 |
| History | A- | 3.7 | 3 | 11.1 |
| Total | 14 | 49.0 | ||
49.0 ÷ 14 = 3.50 GPA.
GPA scale: letter grades to grade points
Most U.S. colleges and high schools use this standard 4.0 scale. The percentage ranges vary slightly between schools.
| Letter grade | Typical percentage | Grade points |
|---|---|---|
| A+ / A | 93–100% | 4.0 |
| A- | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B- | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C- | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D- | 60–62% | 0.7 |
| F | Below 60% | 0.0 |
Weighted vs unweighted GPA
High schools often reward harder classes with a weighted GPA. When you switch on weighting, this calculator adds 0.5 points to honors courses and 1.0 point to AP and IB courses (but never to an F). So an A in an AP class counts as 5.0 instead of 4.0. Colleges usually see both numbers, and many recalculate GPA using their own rules, so it is worth knowing your unweighted GPA too.
How to raise your GPA
- Focus on high-credit courses: a better grade in a 4-credit class moves your GPA more than the same improvement in a 1-credit class.
- Check your school’s retake policy: some schools replace the old grade when you repeat a course.
- Plan ahead: the more credits you have completed, the slower your cumulative GPA moves. Use the cumulative fields above to see what grades you need this term.
If your university reports grades on a 10-point scale as SGPA and CGPA, use our CGPA calculator instead.
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’s credit hours, add everything up, and divide by the total number of credits.
What is a good GPA?
On the 4.0 scale, 3.0 (a B average) is generally considered good, 3.5 and above is very good, and 3.7 or higher is excellent. Competitive colleges and scholarships often look for 3.5+.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses the standard 4.0 scale for every class. A weighted GPA adds extra points for harder classes, usually +0.5 for honors and +1.0 for AP or IB, so it can go above 4.0.
Do pass/fail classes count in GPA?
Usually not. A pass (P) or satisfactory (S) grade earns credits but no grade points, so leave those courses out. A fail on a letter-graded course counts as 0 points and does lower your GPA.
How do I calculate cumulative GPA?
Multiply your current cumulative GPA by the credits you have already completed to get total quality points, add this term’s quality points, and divide by the new total credits. The calculator does this if you fill in the optional fields.
Is an A+ worth 4.0 or 4.3?
Most colleges cap an A+ at 4.0, which is what this calculator uses. A few schools give 4.33 for an A+, so check your school’s grading policy.
