GPA calculator
Average letter grades and credit hours on a US unweighted 4.0 scale. A second mode maps a percentage with one common linear method, and it says your school may use another.
Letter points on the 4.0 scale
| Grade | Points |
|---|---|
| A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| F | 0.0 |
GPA is the sum of each grade's points times its credit hours, divided by total credit hours. An A for 4 credits, a B+ for 3, a B for 3, and a C for 2 produce 16 + 9.9 + 9 + 4 = 38.9 points over 12 credits, which is 3.24.
Percentage mode
Percentage mode is one common conversion method, and your institution's scale may differ. It multiplies the percentage by 4, divides by 100, and caps the result at 4.0. A score of 81 becomes 3.24. A score of 100 becomes 4.0. Other schools' cutoff tables are not applied here.
Questions
Which grade points does this page use?
The letter mode uses a common US unweighted 4.0 table. A is 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, C+ is 2.3, C is 2.0, C- is 1.7, D+ is 1.3, D is 1.0, and F is 0.0. GPA is total grade points divided by total credit hours.
How is the example GPA of 3.24 reached?
Take an A for 4 credits, a B+ for 3, a B for 3, and a C for 2. Grade points are 16, plus 9.9, plus 9, plus 4, which totals 38.9. Credit hours total 12. Divide 38.9 by 12 and you get 3.2416, which this page rounds to 3.24. Your rows use the same arithmetic.
How does the percentage mode work?
Percentage mode multiplies the percent by 4 and divides by 100, and it never goes above 4.0. A score of 100 is 4.0, and 81 is 3.24. This is one common linear method. Schools and countries use other cutoffs, so check your own scale before you treat the number as official.
Are weighted grades included?
Plus and minus grades are already in the letter table. A weighted GPA, honors points, and a 5.0 scale are not included. Credit hours can be whole numbers or halves such as 0.5 or 1.5. Empty rows are skipped. Each counted row needs both a grade and a credit value above zero.
