Unweighted and weighted GPA on the 4.0 scale, with credits and cumulative GPA
GPA = the sum of grade points × credits divided by total credits. On the 4.0 scale an A is 4.0, a B+ 3.3 and a C 2.0. A weighted GPA adds 0.5 for honors and 1.0 for AP or IB classes. The calculator shows unweighted, weighted and cumulative GPA.
GPA = sum of grade points × credits ÷ total credits. On the 4.0 scale a grade of 88% is usually a B+ worth 3.3 grade points, an A counts 4.0 and a C 2.0. Weighted GPAs add 0.5 for honors and 1.0 for AP or IB classes.
| Percentage | Letter grade | Unweighted | Honors | AP / IB |
|---|---|---|---|---|
| 97 % | A+ | 4.0 | 4.5 | 5.0 |
| 94 % | A | 4.0 | 4.5 | 5.0 |
| 91 % | A− | 3.7 | 4.2 | 4.7 |
| 88 % | B+ | 3.3 | 3.8 | 4.3 |
| 85 % | B | 3.0 | 3.5 | 4.0 |
| 81 % | B− | 2.7 | 3.2 | 3.7 |
| 78 % | C+ | 2.3 | 2.8 | 3.3 |
| 75 % | C | 2.0 | 2.5 | 3.0 |
| 71 % | C− | 1.7 | 2.2 | 2.7 |
| 68 % | D+ | 1.3 | 1.8 | 2.3 |
| 65 % | D | 1.0 | 1.5 | 2.0 |
| 61 % | D− | 0.7 | 1.2 | 1.7 |
| 55 % | F | 0.0 | 0.0 | 0.0 |
Multiply the grade points of each course by its credits, add them up and divide by the total credits. 46 grade points over 13 credits give a GPA of 3.54.
An unweighted GPA counts every class on the same 4.0 scale. A weighted GPA adds points for harder classes, commonly 0.5 for honors and 1.0 for AP or IB, so it can exceed 4.0.
Multiply your previous GPA by its credits, add the grade points of the new courses and divide by all credits combined. A 3.4 over 30 credits plus 46 new points over 13 credits gives 3.44.
Most high schools and colleges count an A+ as 4.0. Some colleges award 4.3. The calculator lets you choose the setting your school uses.
Convert the percentage to a letter grade first and then to grade points. On the common scale 88% is a B+, which counts 3.3 points.
Your grade point average turns letter grades into numbers and weights them by credits. On the common 4.0 scale an A is 4.0, an A− 3.7, a B+ 3.3, a B 3.0 and so on down to an F with 0 points. Multiply the grade points of each course by its credits, add everything up and divide by the total credits. A class with more credits therefore moves your GPA more than a one-credit elective.
Example: English A− (3 credits), Algebra II B+ (3 credits), Biology A (4 credits) and US History B (3 credits) give 3.7 × 3 + 3.3 × 3 + 4.0 × 4 + 3.0 × 3 = 46 grade points over 13 credits, an unweighted GPA of 3.54.
An unweighted GPA treats every class the same and tops out at 4.0. A weighted GPA rewards harder classes: many high schools add 0.5 points for honors courses and 1.0 point for AP or IB courses, so an A in an AP class counts as 5.0. In the example above, Algebra II as an honors class and US History as an AP class raise the weighted GPA to 3.88. Failing grades get no bonus.
Schools handle weighting differently, and many colleges recalculate applicants’ GPAs with their own rules. Report the GPA the way your school prints it on the transcript and use the calculator to understand where it comes from.
To combine a new semester with earlier results, enter your previous cumulative GPA and the credits it is based on. The calculator weights both parts by credits: (previous GPA × previous credits + new grade points) ÷ (previous credits + new credits). A 3.4 over 30 credits plus the semester above gives (102 + 46) ÷ 43 = 3.44.
Most high schools and colleges count an A+ as 4.0, the same as an A. Some colleges award 4.3. Choose the setting that matches your school; it only changes the result if you have A+ grades.
To convert a percentage to GPA points, find the letter grade first and then its points. An 88% is a B+ and counts 3.3 points. For a single class grade from assignments, use the grade calculator.
