High School GPA Calculator
Enter your grades, credits and course levels (regular, honors, AP or IB) to get your weighted and unweighted GPA, and add your earlier record for a cumulative GPA.
Calculate your high school GPA
Add each class with its letter grade, level and credits. The calculator uses the standard 4.0 plus/minus scale, adds +0.5 for honors and +1.0 for AP, IB or dual enrollment, and updates both GPAs as you type. Nothing you enter is stored or sent anywhere.
| Course | Grade | Level | Credits | Actions |
|---|---|---|---|---|
Quality points: 20.0 unweighted, 22.0 weighted
Add your earlier record (optional)
For a cumulative GPA, enter the GPA and credits from your earlier years. Fill in the unweighted GPA, the weighted GPA or both.
How to use the calculator
- Enter each class. Type the course name if you like, then pick the letter grade.
- Choose the level. Regular, Honors (+0.5) or AP / IB / Dual enrollment (+1.0). Failing grades get no bonus.
- Set the credits. A full-year course is often 1 credit and a half-year course 0.5. Leave credits on, because courses count in proportion to them.
- Read both GPAs. The unweighted GPA ignores course level. The weighted GPA includes the bonus points.
- Add earlier years. Enter your previous GPA and credits to see your cumulative GPA.
Grade points used
This is the common 4.0 plus/minus scale. Schools differ, so check your own school’s table and bonus rules.
| Grade | Regular | Honors | AP / IB / Dual |
|---|---|---|---|
| A+ / 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 |
A+ is counted as 4.0, as many schools do. Some schools give an A+ 4.3, so your transcript may differ. P, W and I grades are not counted.
How high school GPA is calculated
Convert each grade to grade points, multiply by the course’s credits to get quality points, add them up, and divide by the total credits.
For the weighted GPA, add the level bonus to the grade points of each passing course before multiplying. Here is a worked example with six courses:
| Course | Level | Grade | Credits | Unweighted points | Weighted points |
|---|---|---|---|---|---|
| English 10 | Honors | A− | 1 | 3.7 | 4.2 |
| Algebra II | Regular | B+ | 1 | 3.3 | 3.3 |
| Biology | Honors | B | 1 | 3.0 | 3.5 |
| US History | AP / IB / Dual | A | 1 | 4.0 | 5.0 |
| Spanish 2 | Regular | A | 1 | 4.0 | 4.0 |
| PE | Regular | A | 0.5 | 2.0 | 2.0 |
| Total | 5.5 | 20.0 | 22.0 |
The unweighted GPA is 20.0 ÷ 5.5 = 3.64 and the weighted GPA is 22.0 ÷ 5.5 = 4.00. The points columns show grade points × credits, so the half-credit PE course counts for half as much.
To add earlier years, combine the quality points. If you had a 3.50 unweighted GPA over 30 credits before this term, the cumulative GPA is (3.50 × 30 + 20.0) ÷ (30 + 5.5) = 125.0 ÷ 35.5 = 3.52. Do not average the two GPAs, because the years have different credits. Our guide on how to calculate GPA covers the method in more detail.
Weighted vs unweighted GPA
An unweighted GPA tops out at 4.0 and treats every class the same. A weighted GPA gives extra points for harder classes, so it can be above 4.0. In the example above, the AP US History A is worth 5.0 and the Honors Biology B is worth 3.5. A weighted 4.0 can therefore include some B’s in advanced courses, which is not the same as straight A’s. Many colleges recalculate GPAs on their own scale, so it is useful to know both numbers. See what a 4.0 GPA means for more.
What is a good high school GPA?
It depends on your goals. A 3.5 is a strong record, and a 4.0 unweighted means straight A’s. Selective colleges often report higher averages for admitted students, so check the range for each school you want. Read the details in our guides on a 3.5 GPA and a 4.0 GPA. Colleges also look at course difficulty, grade trends and the rest of your application.
How to raise your GPA
- Focus on high-credit courses. They move your GPA the most.
- Know the gap to the next letter. Use the final grade calculator to see what you need on the exam.
- Track each course. Enter your scores in the weighted grade calculator to find your weakest category.
- Convert percentages. If your portal shows percentages, use the letter grade calculator to find the letter.
- Show an upward trend. Colleges notice improvement over time.
Frequently asked questions
Why doesn’t my GPA match my transcript?
Schools use different scales and bonus rules. Some give A+ a 4.3, some round differently, and some exclude certain courses. Use this result as an estimate and check your school’s policy.
Do freshman grades count?
At most schools, yes. Your cumulative high school GPA usually includes grades from ninth grade onward, but check how your school and each college handle them.
Do electives and PE count?
Usually, yes, in proportion to their credits. Some schools exclude certain courses from the GPA, so check your transcript.
Do AP exam scores change my GPA?
No. The GPA is based on your course grades. The AP exam score of 1 to 5 is reported separately.
What happens if I retake a class?
It depends on your school. Some replace the old grade, some average the two and some count both. Ask your counselor before you enter it.
Do pass/fail, withdrawals and incompletes count?
Usually not. This calculator ignores P, W and I when you pick the not counted option.
Can a GPA be higher than 4.0?
Only a weighted GPA can, because AP, IB and honors courses add bonus points. An unweighted GPA stops at 4.0.
Do colleges use weighted or unweighted GPA?
It varies. Many colleges recalculate GPA on their own scale or look at both, so it helps to know both numbers.
