GPA calculator
GPA calculator: weighted and unweighted
Add your courses and grades to get your unweighted GPA on a 4.0 scale, your weighted GPA (Honors +0.5, AP, IB and dual enrollment +1.0, adjustable), your core GPA and your 10th–11th GPA. Or convert one GPA from a 5.0, 6.0 or percent scale to 4.0. Free, no sign-up, and nothing leaves your browser. Then see what your GPA means for your odds at 700+ colleges on Chance me.
How to calculate your GPA
Turn each final grade into points (A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on), multiply by the course's credits, add those up, and divide by the total credits. That's your unweighted GPA on a 4.0 scale.
Example, five full-year courses (1 credit each): English A (4.0), Algebra II A- (3.7), Chemistry B+ (3.3), US History A (4.0), Spanish III B (3.0). Points: 4.0 + 3.7 + 3.3 + 4.0 + 3.0 = 18.0. Divide by 5 credits: 3.60 unweighted. If Chemistry and US History were AP (+1.0 each), the weighted total is 20.0, so 4.00 weighted.
Half-year courses count half: a semester course is 0.5 credits, so it moves your GPA half as much as a full-year course.
Weighted vs. unweighted GPA
Unweighted GPA treats every class the same: an A is a 4.0 whether it's regular or AP. Weighted GPA adds a bonus for harder classes, most often +0.5 for Honors and +1.0 for AP, IB and dual-enrollment courses, so it can go above 4.0. High schools weight differently, which is why colleges look at both and many recalculate.
Converting weighted to unweighted: you can't do it exactly from one number, because you need to know which classes got a bonus. Enter your courses above and we compute both. For a rough estimate from one number, use Quick convert: a 4.5 on a 5.0 scale is about a 3.75 unweighted.
GPA scales
| Letter | 4.0 scale |
|---|---|
| A+ | 4.0 |
| 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 |
Percent grades: 93–100 is an A (4.0), 90–92 an A- (3.7), 87–89 a B+ (3.3), 83–86 a B (3.0), 80–82 a B- (2.7), and so on down to below 65, an F. Some schools give an A+ a 4.3; colleges almost always cap it at 4.0.
How colleges actually read your GPA
Admissions offices rarely take your school's GPA at face value. Many recalculate it: unweighted, core subjects only (English, math, science, social studies and world language), often for 10th and 11th grade, since that's what they'll see when you apply. The University of California, for example, uses 10th and 11th grade courses. They read it next to your school's profile, which shows how hard your school grades and which advanced courses you could have taken. Rigor matters: an A- in AP Chemistry usually reads better than an A in a regular class.
That's why the calculator shows your core GPA, your 10th–11th GPA and how many of your courses were Honors or AP, not just one number.
What's a good GPA for the colleges you want?
It depends on the college. At the most selective schools, most admitted students have close to a 4.0 unweighted; at many good colleges, admitted students cluster between 3.3 and 3.8. Your odds also depend on your test scores, your school and the round you apply in. Chance me puts all of that together for every college, round by round. Browse colleges in the rankings or by major.
