Curious where this might rank?
illustrative onlyThis is a rough estimate based on a typical bell-curve assumption, not your school's real grade distribution. Only your school's registrar can give you an official class rank.
How do you calculate high school GPA? Turn each letter grade into points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0), add them up, and divide by the number of classes. If your classes have different credit values, multiply each grade's points by its credits first, then divide by total credits. Example: A, B, A, C, B gives 16 รท 5 = 3.2.
๐ How to use this calculator
- Enter your classes. The name is optional, but it helps you keep track.
- Pick the grade from your report card, or the one you expect to get.
- Set the credits. Most high school classes are 1 credit (or 0.5 for a semester). Leave them all equal if your school doesn't use credits.
- Press Calculate GPA. The result updates as you change grades.
This tool shows one term on a flat, unweighted 4.0 scale. If you take Honors or AP classes, or want all four years together, use the Cumulative GPA Calculator.
๐ The GPA formula, with an example
Worked example. A student takes five 1-credit classes this term and earns an A (English), B+ (Algebra II), A- (Biology), B (World History) and A (Art). Grade points: 4.0, 3.3, 3.7, 3.0, 4.0. The sum is 18.0 across 5 credits, so GPA = 18.0 รท 5 = 3.60.
Grade scale used by this calculator
| Letter | Typical % | Points |
|---|---|---|
| A | 93โ100 | 4.0 |
| A- | 90โ92 | 3.7 |
| B+ / B / B- | 87โ89 / 83โ86 / 80โ82 | 3.3 / 3.0 / 2.7 |
| C+ / C / C- | 77โ79 / 73โ76 / 70โ72 | 2.3 / 2.0 / 1.7 |
| D+ / D | 67โ69 / 60โ66 | 1.3 / 1.0 |
| F | Below 60 | 0.0 |
Percentage ranges differ from school to school, and a few schools give an A+ 4.3 points. Your school's own grading policy always wins. The "approx. percentage" in the result is just GPA ร 25, a quick estimate and not an official conversion.
โ๏ธ Weighted vs unweighted GPA
Unweighted GPA gives every class the same scale, so an A is a 4.0 whether it's in Art or AP Chemistry. Weighted GPA adds bonus points for harder classes, commonly +0.5 for Honors and +1.0 for AP or IB, so it can go above 4.0. Many colleges look at both, and often recalculate their own number from your transcript. The Cumulative GPA Calculator shows both side by side.
๐ What is a good high school GPA?
| Unweighted GPA | What it usually means |
|---|---|
| 3.7 โ 4.0 | Excellent. Competitive for selective colleges and top scholarships |
| 3.5 โ 3.69 | Strong. High honor roll at many schools |
| 3.0 โ 3.49 | Solid. Meets most honor roll and National Honor Society minimums |
| 2.0 โ 2.99 | Average. Good standing, with fewer scholarship options |
| Below 2.0 | Often academic probation or a warning |
Honor roll, NHS chapter and athletic eligibility cutoffs are set by your school, your chapter and your athletic association, so ask your counselor for the exact numbers. College admissions also look at course rigor, test scores, essays and activities, not GPA alone.
๐ How the rank estimate works
Real class rank depends on every classmate's grades, which only your school has. The estimate above assumes GPAs in a class follow a bell curve around the average you enter, with a typical spread of about 0.5. Roughly, a GPA 1.0 above average lands in the top 2โ5%, 0.5 above lands in the top 15โ20%, and a GPA near the average lands in the middle. If your school publishes an average GPA, enter it instead of the default 3.0 for a better guess. Many schools no longer rank students at all.
๐ How to raise your GPA
- Start early. A bad first term is hard to dilute later, because every term adds to the same average.
- Check credits. A grade in a 1-credit class moves your GPA twice as much as the same grade in a 0.5-credit class.
- Try "what if" grades in the calculator before final exams to see which class matters most.
- Ask about retakes. Some schools replace or average a retaken grade, others don't.
โ Frequently asked questions
What's a good high school GPA?
A 3.5 or above is generally strong for college admissions, 3.0โ3.49 is solid, and below 2.5 may limit options at selective schools. Course rigor and the specific colleges you're targeting matter too.
How do I calculate my GPA if I only have percentages?
Convert each percentage to a letter grade using your school's scale, then to grade points. If your school doesn't publish a scale, ask your counselor, since cutoffs vary.
Is this my real class rank?
No. It's a statistical estimate based on an assumed bell curve. Your real rank, if your school calculates one, comes from your registrar comparing actual GPAs.
Does this include Honors or AP weighting?
No, this page uses a flat unweighted 4.0 scale. For Honors and AP bonus points, use the Cumulative GPA Calculator.
What GPA do I need for the honor roll?
Many schools set honor roll around 3.5 and high honors around 3.7, but this varies. Check your student handbook for your school's cutoffs.
Do colleges use weighted or unweighted GPA?
Many colleges recalculate GPA from your transcript using their own method, often focusing on core academic classes. Report whichever one a form asks for, and read the label carefully.
Can I raise my GPA in one semester?
You can, but the more classes you've already completed, the slower your overall GPA moves. A strong term helps most when you're early in high school.
How is this different from a college GPA calculator?
College calculators use semester credit hours, where courses can be 1 to 5 credits. This one is built for high school classes, which are usually equal in credit. Try the College GPA Calculator for university courses.
