Work out your college or high school GPA from your letter grades and credits. See your weighted and unweighted GPA, your new overall GPA, and the grades you need to raise it.
Choose your grades, enter credits and press Calculate GPA. Your GPA, a course-by-course breakdown and the math will appear here.
How to use the GPA calculator
- Pick College or High school. High school shows both your weighted and unweighted GPA.
- Add one row per course. Choose the letter grade and enter the credits from your transcript. In high school, also pick Regular, Honors or AP/IB.
- Turn on Include my GPA so far to combine this term with your earlier GPA.
- Turn on Plan for a target GPA to see the GPA you need on your next courses.
How GPA is calculated
Each letter grade has a number of grade points. Multiply each course’s grade points by its credits, add them up, and divide by the total credits:
GPA = (points₁ × credits₁ + points₂ × credits₂ + …) ÷ (credits₁ + credits₂ + …)Courses with more credits count for more. An A in a 4-credit class lifts your GPA more than an A in a 1-credit class.
Worked example
English A (3 credits), Calculus B+ (4 credits), Biology A− (4 credits) and History B (3 credits):
4.0 × 3 + 3.3 × 4 + 3.7 × 4 + 3.0 × 3 = 12 + 13.2 + 14.8 + 9 = 49 grade points. Divided by 14 credits, that is a 3.50 GPA.
Grade points for each letter
This is the standard US 4.0 scale. The Honors and AP/IB columns show the common weighted values used by many high schools. Your school may use different ones, so check your student handbook.
| Letter | Grade points | Honors | AP/IB |
|---|---|---|---|
| A+ | 4.0 (4.3 at some schools) | 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 |
Cumulative GPA
Your cumulative (overall) GPA covers every course you have taken, not just this term. To combine them, turn your old GPA back into grade points by multiplying it by your credits so far.
With a 3.20 GPA over 30 credits, you have 3.2 × 30 = 96 grade points. Add the 49 from the example term and divide by all 44 credits: 145 ÷ 44 = 3.30. A strong term moves your overall GPA less the more credits you already have.
Weighted vs unweighted GPA
An unweighted GPA uses the 4.0 scale for every class. A weighted GPA adds a bonus for harder classes, usually 0.5 for Honors and 1.0 for AP or IB, so it can go above 4.0.
Honors English A, AP Biology B+, Algebra B and Spanish A−, all 1 credit, give 4.5 + 4.3 + 3.0 + 3.7 = 15.5 ÷ 4 = 3.88 weighted. Without the bonuses it is 4.0 + 3.3 + 3.0 + 3.7 = 14 ÷ 4 = 3.50 unweighted. Colleges often look at both, and many recalculate GPA their own way.
What GPA do I need to raise my GPA?
Pick the GPA you want and the credits you will take next. With 145 grade points over 44 credits, a 3.40 overall after 15 more credits needs 3.4 × 59 = 200.6 grade points. You have 145, so 200.6 minus 145 leaves 55.6 to earn over 15 credits: 55.6 ÷ 15 = 3.71.
If the planner says a target is not possible, even straight A’s on the next courses cannot get you there. Adding more credits gives you more room, which is why GPA is easier to raise early on.
Frequently asked questions
Is an A+ worth 4.0 or 4.3?
Most US colleges and high schools count an A+ as 4.0. Some count it as 4.3. Use the A+ setting in the calculator to match your school.
Do Pass, Withdrawn or Incomplete courses count?
Usually not. P, W and I grades carry no grade points, so the calculator leaves them out and tells you it did. A failed pass/fail course can count at some schools, so check your school’s policy.
What if I retook a course?
Many schools replace the old grade with the new one. If yours does, enter only the new grade. If both grades count, enter both as separate rows.
What is a good GPA?
A 3.0 is a B average and a 4.0 is straight A’s on an unweighted scale. What counts as good depends on your goal, such as a scholarship, honors program or graduate school, so check the requirement for the one you want.
Why is my GPA different from my transcript?
Schools differ on A+ values, weighting, repeated courses and rounding. The calculator shows the exact math, so you can compare it with your school’s rules.
Are my grades saved anywhere?
No. The calculation runs in your browser and nothing you type is sent to our server.
