1Type in the name of each class you're taking — like "English 10" or "AP Chemistry." If you leave it blank, that's fine too, the calculator still works.
-
2Choose your course level — Regular, Honors, or AP. This matters because Honors adds +0.5 and AP adds +1.0 to your grade points, boosting your weighted GPA.
-
3Select the letter grade you received (or expect to receive) in each class — from A+ all the way down to F.
-
4Click "+ Add Class" to keep adding more courses. Hit the × button on any row to remove it if you made a mistake or don't need that class anymore.
-
5Hit "Calculate GPA" and you'll instantly see your Weighted GPA, Unweighted GPA, total courses counted, and a progress bar showing where you stand on the 5.0 scale.
-
6Use "Copy Result" to copy your GPA to clipboard and share it anywhere. Hit "Reset" to start fresh and calculate for a new semester.
High School GPA Calculator for Weighted and Unweighted GPA
The bell rings at the end of third period, and a high school junior in Virginia stays behind with a question for her counselor. Her report card shows a weighted GPA above 4.0, but a college application asks for an unweighted GPA, and the two numbers do not match.
That mix-up is common: high schools report GPA in two ways, and colleges read them in two ways. A High School GPA Calculator sorts it out in minutes. Enter each course, its grade, its credits, and its level, and this GPA calculator for high school students returns both numbers.
Quick answer: A High School GPA Calculator turns each letter grade into grade points on the 4.0 scale, multiplies those points by course credits, and divides total quality points by total credits. The unweighted result stops at 4.0. The weighted result adds bonus points for AP, IB, or honors courses, so it can pass 4.0. The exact bonus comes from school policy.

How to use the High School GPA Calculator
Five steps calculate GPA.
- List every course from the term.
- Enter the letter grades earned, from the report card or transcript.
- Enter the credits for each course: often 1.0 for a full-year course, 0.5 for a semester course.
- Mark the level of each course: regular, honors, AP, or IB.
- Read both results: unweighted GPA and weighted GPA.
A worked example with real numbers
Say a junior in Virginia runs six fall semester courses through the High School GPA Calculator, using the common bonus of +1.0 for AP and +0.5 for honors.
| Course | Level | Grade | Credits | Grade points | Quality points |
|---|---|---|---|---|---|
| AP English Language and Composition | AP | A- | 1.0 | 3.7 | 3.7 |
| Honors Chemistry | Honors | B+ | 1.0 | 3.3 | 3.3 |
| Algebra II | Regular | B | 1.0 | 3.0 | 3.0 |
| U.S. History | Regular | A | 1.0 | 4.0 | 4.0 |
| Spanish III | Regular | B- | 1.0 | 2.7 | 2.7 |
| Health and Physical Education | Regular | A | 0.5 | 4.0 | 2.0 |
| Totals | 5.5 | 18.7 |
Unweighted GPA = 18.7 / 5.5 = 3.40.
Weighted: AP English rises from 3.7 to 4.7 and Honors Chemistry from 3.3 to 3.8. Total = 20.2. Weighted GPA = 20.2 / 5.5 = 3.67.
The GPA formula, with each variable explained
A High School GPA Calculator applies one GPA calculation for grade point average:
GPA = total quality points / total credit hours
- Grade points: the number tied to letter grades on the 4.0 scale: A 4.0, B 3.0, C 2.0, D 1.0, F 0.0, with plus and minus grades in between.
- Quality points: grade points multiplied by course credits. A B (3.0) in a 1.0-credit course gives 3.0 points, and 1.5 in a 0.5-credit course.
- Total credit hours: every credit attempted in the term.
GPA is a weighted average, not a simple average: credits decide how much each grade counts. The same GPA formula gives a cumulative GPA across terms: add prior quality points to new term quality points, then divide by all credits combined. A cumulative GPA calculator does this step for you. Example: 35.2 prior points (3.2 GPA, 11.0 credits) plus 18.7 fall points (5.5 credits) = 53.9 over 16.5 credits, so cumulative GPA = 53.9 / 16.5 = 3.27.
How to read your results on the US grading scale
This High School GPA Calculator uses the high school GPA scale below, and an unweighted GPA calculator caps the result at 4.0 on the 4.0 GPA scale.
| Percentage | Letter grade | Grade points |
|---|---|---|
| 97-100 | A+ | 4.0 |
| 93-96 | A | 4.0 |
| 90-92 | A- | 3.7 |
| 87-89 | B+ | 3.3 |
| 83-86 | B | 3.0 |
| 80-82 | B- | 2.7 |
| 77-79 | C+ | 2.3 |
| 73-76 | C | 2.0 |
| 70-72 | C- | 1.7 |
| 67-69 | D+ | 1.3 |
| 63-66 | D | 1.0 |
| 60-62 | D- | 0.7 |
| Below 60 | F | 0.0 |
Three details catch students out. First, A+ and A both sit at 4.0 unweighted, so a plus at the top does not lift the GPA past 4.0. Second, GPA after failing a class drops sharply, since an F gives 0.0 quality points while its credits still count in the divisor. Third, cutoffs vary by school, so a 90 might be an A- in one school and an A in another. When grades arrive as percentages, a percentage to GPA conversion comes first, then the letter grade to GPA step follows the scale.
Weighted vs unweighted GPA for the same transcript
Here is the same fall transcript, shown both ways, on the same high school GPA scale. The weighted column uses the example bonus of +1.0 for AP and +0.5 for honors. Running the High School GPA Calculator on this transcript gives both columns at once: a weighted GPA calculator adds the bonus first, while an unweighted GPA calculator treats courses the same.
| Course | Grade | Unweighted points | Weighted points |
|---|---|---|---|
| AP English Language | A- | 3.7 | 4.7 |
| Honors Chemistry | B+ | 3.3 | 3.8 |
| Algebra II | B | 3.0 | 3.0 |
| U.S. History | A | 4.0 | 4.0 |
| Spanish III | B- | 2.7 | 2.7 |
| Health and PE | A | 2.0 | 2.0 |
| Totals (5.5 credits) | 18.7 | 20.2 | |
| GPA | 3.40 | 3.67 |
The unweighted GPA compares grades only. The weighted GPA rewards course rigor, so it can pass 4.0, up to 5.0 on a 5.0 GPA scale.
Weighting systems vary by school: AP courses and IB courses can carry bonus points when a school weights them, but some schools weight AP only. The AP bonus points and honors bonus points here are an example, so check school policy first. The weighted grade calculator on this site can model one course grade with weights applied.
What one grade change does
Small grade changes move the GPA by a visible amount. The table below keeps the same transcript and changes only Spanish III.
| Scenario | Unweighted GPA | Weighted GPA |
|---|---|---|
| Current transcript (Spanish III B-) | 3.40 | 3.67 |
| Spanish III rises to B | 3.45 | 3.73 |
| Spanish III rises to A | 3.64 | 3.91 |
The math: a B- to B lift adds 0.3 quality points, giving 19.0 / 5.5 = 3.45 unweighted and 20.5 / 5.5 = 3.73 weighted. A B- to A lift adds 1.3 points, giving 3.64 and 3.91. A change in a 0.5-credit course moves the GPA about half as much.
4 ways students use a high school GPA calculator
1. A junior plans college applications. Junior year GPA planning starts with both numbers, including what counts as a good GPA for college. The Virginia junior from the opening scene runs them before she fills out forms. since college admissions forms vary: one asks for weighted GPA, another for unweighted GPA.
2. A student checks whether a target GPA is still in reach. After a rough semester, a student enters new term grades plus prior GPA and credits into a cumulative GPA calculator modeling how to raise GPA next term. A final grade calculator pairs well here, showing the exam score needed for a target course grade.
3. A parent tracks a sophomore mid-year. A sophomore GPA check each term, using a semester grade calculator and entering semester grades as they arrive, gives a semester GPA picture, not a surprise at year end. A parent can spot a slide early, while help can still change the outcome.
4. A senior weighs course load against GPA risk. Senior year GPA planning means weighing course load against GPA risk: a B in an AP course can beat an A in a regular course on a weighted scale, but loses on an unweighted scale. A weighted GPA calculator shows the trade-off in plain figures.
Common mistakes that throw off a GPA result
Averaging term GPAs. Two semesters with different credit totals cannot be averaged straight. Recompute from quality points.
Leaving a course out, or counting a course that should not count. Pass/fail courses, withdrawals, and incompletes are often excluded from GPA math. Counting one as a letter grade shifts the result.
Using a bonus the school does not give. Marking a course as AP or honors when the school weights it as regular inflates the result.
Rounding GPA figures too early. Rounding before adding lets small errors stack. Round the GPA to two decimal places at the end.
Tips for accurate results
Copy grades from the transcript, not from memory, and calculate GPA each term. Confirm the school percentage scale and weighting bonus before entering anything in the High School GPA Calculator. Enter exact credits, including 0.5 for a semester course, and note each semester GPA and check GPA each term, so the GPA trend stays visible.
When a GPA calculator is not enough on its own
A High School GPA Calculator handles the arithmetic, not school policy. Curved tests, grade replacement rules, repeated courses, incompletes, and transfer credits follow rules that differ by school. A school counselor or teacher can confirm how a repeated course appears on the transcript and whether a replaced grade still counts.
Treat High School GPA Calculator results as a GPA estimate for planning. The official transcript and the school gradebook stay final, and any GPA for scholarships must match the transcript.

Frequently asked questions
What is a good GPA in high school?
A 3.0 GPA equals a B average on the 4.0 scale, and a 3.5 or higher counts as strong for most college plans. What counts as a good GPA for college depends on the colleges a student aims for, the rigor of the courses taken, and the GPA trend across terms. A rising GPA across junior and senior year reads better than a flat one, even when the final number matches.
How is a weighted GPA different from an unweighted GPA?
An unweighted GPA puts every course on the same 4.0 scale, no matter how hard the course was. A weighted GPA adds bonus points for AP, IB, or honors courses, so it can rise above 4.0. The same transcript can give two different numbers, and both are correct under their own rules.
Do colleges look at weighted or unweighted GPA?
Application forms vary. Some ask for weighted GPA, some ask for unweighted GPA, and some ask for both. A student should report the exact number the form asks for, taken from the transcript, and keep both figures ready before starting applications.
How do I calculate GPA for AP and honors classes?
Convert each letter grade to grade points on the 4.0 scale, then add the school bonus for advanced courses. A common example adds 1.0 for AP or IB and 0.5 for honors, but school policy is final and systems vary. Multiply each result by course credits, add all quality points, and divide by total credits.
What happens to my GPA if I fail a class?
An F gives 0.0 quality points, while its credits still count in the divisor at most schools, so GPA after failing a class drops sharply. Retake and grade replacement rules vary by school, so a counselor should confirm whether a retaken grade replaces the F or sits beside it on the transcript.
Can a GPA go above 4.0?
Yes, but only a weighted GPA. The unweighted scale caps at 4.0, since A+ and A both equal 4.0. A weighted GPA passes 4.0 when bonus points from AP, IB, or honors courses push course values above 4.0.
