How to Use the High School GPA Calculator
- Type a course name — optional, but it makes the saved list easier to read.
- Pick the letter grade you earned.
- Enter the credits. Most high school courses are 1 credit; leave it at 1 if you are not sure.
- Choose Regular, Honors or AP / IB. The weighted GPA updates as you go. Use + Add course for anything past the first four rows.
How the Calculation Works
GPA is a credit-weighted average, not a plain average of your grades. Each course earns quality points (grade points × credits); the total is divided by total credits:
GPA = Σ (grade points × credits) ÷ Σ credits
That is why a B in a two-credit course pulls the average more than a B in a half-credit elective.
High School GPA Scale: Letter Grades, Percentages, 4.0 Values
| Letter | Percentage | Regular | Honors | AP / IB |
|---|---|---|---|---|
| A+ / A | 93–100 | 4.0 | 4.5 | 5 |
| A− | 90–92 | 3.7 | 4.2 | 4.7 |
| B+ | 87–89 | 3.3 | 3.8 | 4.3 |
| B | 83–86 | 3.0 | 3.5 | 4 |
| B− | 80–82 | 2.7 | 3.2 | 3.7 |
| C+ | 77–79 | 2.3 | 2.8 | 3.3 |
| C | 73–76 | 2.0 | 2.5 | 3 |
| C− | 70–72 | 1.7 | 2.2 | 2.7 |
| D+ | 67–69 | 1.3 | — | — |
| D | 63–66 | 1.0 | — | — |
| D− | 60–62 | 0.7 | — | — |
| F | 0–59 | 0.0 | — | — |
This is the most common US high school scale. Your school's exact cutoffs may differ — check your student handbook.
Weighted vs Unweighted High School GPA
Unweighted GPA caps every course at 4.0. weighted GPA gives extra points for harder courses, so a student who takes Honors and AP classes can finish above 4.0. Colleges see both: many recalculate your GPA on their own scale using your transcript, so the number here is a working estimate rather than the figure an admissions office will use.
Honors and AP Weighting: What Changes
The convention most US high schools follow is +0.5 for Honors and +1.0 for AP or IB, applied before credits are multiplied in. A B+ (3.3) in an Honors class counts as 3.8 weighted; the same B+ in an AP class counts as 4.3.
Two Worked Examples
Example A — Unweighted
| Course | Grade | Points | Credits | Points × Credits |
|---|---|---|---|---|
| English | A | 4.0 | 1 | 4.0 |
| Algebra II | B+ | 3.3 | 1 | 3.3 |
| Chemistry | A− | 3.7 | 1 | 3.7 |
| US History | A | 4.0 | 1 | 4.0 |
| Spanish | B | 3.0 | 1 | 3.0 |
| PE | A | 4.0 | 1 | 4.0 |
22.0 ÷ 6 credits = 3.67
Example B — the same six courses, two of them Honors
| Course | Grade | Points |
|---|---|---|
| Algebra II (Honors) | B+ | 3.8 |
| Chemistry (Honors) | A− | 4.2 |
| English | A | 4.0 |
| US History | A | 4.0 |
| Spanish | B | 3.0 |
| PE | A | 4.0 |
23.2 ÷ 6 credits = 3.87. Same courses, same grades — the weighted result is 3.87 against 3.67 unweighted, purely from course level.
What Your GPA Means for College Admissions
| GPA (4.0 scale) | What it generally means |
|---|---|
| 3.8 – 4.0+ | Strong for highly selective colleges, and keeps most merit scholarship options open. |
| 3.5 – 3.7 | Competitive at most state flagships and many private colleges. |
| 3.0 – 3.4 | Meets the published minimum at many state universities; test scores and essays carry more weight. |
| 2.5 – 2.9 | Open-admission and some regional campuses stay in range; community college transfer is a well-worn route to a four-year degree. |
| Below 2.5 | Focus on a recovery term — grade replacement policies, a stronger junior year, and transfer pathways matter more than the number right now. |
These are general ranges, not admission guarantees. Course rigor and test scores move the line at selective schools.

Frequently Asked Questions
How do I calculate my GPA for high school?
Multiply each course's grade points by its credits, add those products together, then divide by your total credits. On the standard 4.0 scale an A is 4.0, a B is 3.0 and a C is 2.0. Six one-credit courses graded A, B+, A−, A, B and A come out to 22.0 ÷ 6 = 3.67.
Is a 3.7 GPA an A or B?
A 3.7 is an A−, which is roughly 90–92% in most high schools. It is not an A: a straight A is 4.0 on the unweighted scale, and A+ does not go above 4.0 in unweighted calculations.
Is a 2.7 GPA bad in high school?
A 2.7 is a B−. It is below average for college-bound students but far from fatal — many state universities still admit at this level, and the biggest gains are available in your first two years of high school. Raising a 2.7 to a 3.2 by graduation is a realistic goal and changes your college options considerably.
Is 75% a 3.0 GPA?
No. 75% usually falls in the C range, which is 2.0 on the 4.0 scale. A 3.0 is a B, roughly 83–86%. The two numbers are often confused because some schools report a 75 average and a 3.0 side by side using different scales.
Weighted vs unweighted GPA — what's the difference?
Unweighted GPA caps every course at 4.0 no matter how hard it is. Weighted GPA adds extra points for advanced coursework — typically +0.5 for Honors and +1.0 for AP or IB. The same six courses in our worked examples score 3.67 unweighted and 3.87 weighted, because two of them were Honors classes.
Should I use 1 credit per class?
Most US high schools give each course one credit, so 1 is the right default. If your school assigns different credit values — a lab science at 1.5, a half-year elective at 0.5 — enter the real numbers, since credits act as the weight in the calculation.
My school uses a 5.0 scale. Can I use this calculator?
Yes. Pick the course level that matches your school's rules: on a 5.0 scale, an A in an AP class is worth 5.0, which is exactly what this calculator produces when you set a course to AP and grade it A.
Does GPA include electives, PE, and art?
Usually yes, because they carry credit and count toward graduation. Some districts exclude PE or give it pass/fail, and a few calculate a separate academic GPA for college applications. Your student handbook is the final word.
