Add your courses (4.0 scale). Optionally include your current GPA and credits to get a new cumulative GPA.
About this tool
Pick a letter grade and enter the credit hours for each course to get your semester GPA. If you also enter your current cumulative GPA and credits earned, it combines them into a new cumulative GPA. It uses the standard 4.0 scale and runs in your browser, so nothing is stored.
How to use it
Each row is one course: choose the grade and type the credits (usually 3 or 4). Add more rows as needed. The semester GPA updates as you go. For the cumulative figure, fill in the two optional boxes with the numbers from your transcript.
How GPA is calculated
Multiply each course's grade points by its credits, add them up, and divide by total credits. A 4-credit A (4.0) and a 3-credit B (3.0) give (16 + 9) / 7 = 3.57. Credits matter: a bad grade in a 4-credit course hurts more than the same grade in a 1-credit course.
Letter grade to grade points (4.0 scale)
| Letter grade | Grade points |
|---|---|
| A+ | 4.0 (some schools 4.3) |
| 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 |
| D- | 0.7 |
| F | 0.0 |
Many schools do not award an A+ above 4.0, and some use different values for plus and minus grades. Check your school's own scale.
Cumulative GPA example
If you have a 3.20 GPA over 45 credits and earn a 3.60 across 15 new credits, your new cumulative is (3.20 x 45 + 3.60 x 15) / 60 = 3.30. The more credits you already have, the less a single semester moves the total.
Things to watch out for
Pass/fail and withdrawn courses usually do not count toward GPA, so leave them out. Repeated courses may be replaced or averaged depending on your school's policy. Weighted GPAs (honors or AP classes can score up to 5.0) use a different scale. This tool gives an estimate, and your registrar's figure is the official one. To work out the grade you need on a final, use the grade calculator.
Frequently asked questions
Multiply each course's grade points by its credit hours, add the results, and divide by the total credits. An A is 4.0, a B is 3.0, a C is 2.0.
Add the total grade points from all terms (GPA times credits for each) and divide by total credits. This calculator does it if you enter your current GPA and credits.
Usually not. Pass/fail and withdrawn courses typically do not affect GPA, but check your school's policy.
