How GPA is calculated
A grade point average is a credit-weighted average of your grades. Each letter grade maps to a number of grade points on a 4.0 scale. For each course, multiply those grade points by the number of credits the course is worth. Add up the results for every course, then divide by the total credits. Courses with more credits pull the average more than courses with fewer credits.
GPA formula
Example: a four-course semester
Suppose you take a 4-credit course and earn an A (4.0), a 3-credit course and earn a B+ (3.3), a 3-credit course and earn a B (3.0), and a 3-credit course and earn an A- (3.7). The grade points are 16.0, 9.9, 9.0, and 11.1, which add up to 46.0 across 13 credits. Dividing 46.0 by 13 gives a semester GPA of 3.54.
If you came into the semester with a 3.40 GPA over 60 credits, your prior grade points are 204.0. Adding this semester gives 250.0 grade points over 73 credits, so your new cumulative GPA is 3.42.
Letter grade to grade points
The table below shows the standard 4.0 scale used by this calculator, along with the weighted values applied when a course is marked Honors (+0.5) or AP/IB (+1.0). An F earns zero points on every scale.
| Letter grade | Unweighted | Honors | AP / IB |
|---|---|---|---|
| A+ | 4.0 | 4.5 | 5.0 |
| A | 4.0 | 4.5 | 5.0 |
| A- | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B- | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| C- | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D- | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
Frequently asked questions
What is the difference between weighted and unweighted GPA?
An unweighted GPA treats every course the same and tops out at 4.0. A weighted GPA adds extra points for harder courses, typically +0.5 for honors and +1.0 for AP or IB, so it can exceed 4.0. Many high schools report both. Colleges often recalculate GPA using their own method, so the unweighted figure is the most portable one.
What is a good GPA?
On a 4.0 scale, a 3.0 is a B average and is a common threshold for scholarships, graduate programs, and employer screens. A 3.5 or higher is generally considered strong, and a 3.7 or higher is competitive for selective programs. What counts as good depends on your school's grading norms and the programs you are applying to.
How does cumulative GPA work?
Cumulative GPA is the credit-weighted average of every graded course you have taken, not an average of your semester GPAs. To update it, multiply your prior GPA by your prior credits to recover your total grade points, add this semester's grade points, and divide by the combined credits. Because earlier credits accumulate, each new semester moves a cumulative GPA less than the one before.
Do pass/fail classes count toward GPA?
Usually not. A passing grade in a pass/fail course earns credit but carries no grade points, so it is excluded from the GPA calculation. A failing grade is sometimes recorded as an F and does count, depending on the school. Leave pass/fail courses out of the rows above unless your school tells you otherwise.
Why does my school's GPA differ from this one?
Schools vary in how they treat plus and minus grades, how much weight they give to advanced courses, and whether repeated or transfer courses are included. This calculator uses the most common 4.0 scale. Check your transcript or registrar's policy for the exact scale your school uses.
