High School GPA Calculator (Weighted and Unweighted)

Give each class a letter grade, look up its points on your school's scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0), add the points and divide by the number of classes. If your school counts credits, multiply each class's points by its credits first and divide by the total credits. This calculator does both and shows every step in the table under the result.

An unweighted GPA treats every class the same and tops out at 4.0. A weighted GPA adds a bonus for harder classes, most often 0.5 for Honors and 1.0 for AP, IB and dual enrollment, so an A in AP Biology counts 5.0 instead of 4.0. Colleges usually see both, and many recalculate your GPA with their own rule, so the two numbers here are a planning tool, not a promise.

Under the common rule, a passing grade in an AP class gets 1.0 extra point and one in Honors gets 0.5, compared with the same grade in a regular class, so an AP A counts 5.0 and an Honors A 4.5. Mark the level of each class above and the calculator shows the bonus per class; the raise GPA calculator shows how much those bonuses move your GPA over the years.

The average high school GPA in the US is 3.11 unweighted (NAEP, class of 2019), so a 3.5 is well above it. Each college publishes the GPA range of its admitted students in its Common Data Set or class profile, so compare your unweighted GPA with the colleges on your list. Your school's grading scale and how many weighted classes it offers change what those numbers mean, so counselors compare students within the same school.

3.11 for the class of 2019, according to the NAEP High School Transcript Study published in March 2022, up from 3.00 in 2009. That figure is unweighted, so compare it with your unweighted GPA: a weighted 3.6 can come from an unweighted 2.6 when every class carries the AP bonus, and that is still below 3.11. Colleges recalculate GPAs their own way, so the unweighted number on the 4.0 scale is the fair comparison.

Mark each AP class with the AP level in the row and turn Weighted on. On the common weighting an AP A counts 5.0 instead of 4.0 and an AP B 4.0 instead of 3.0. The calculator shows the weighted and the unweighted GPA side by side, because colleges ask for both and recalculate with their own bonuses.

Yes. Schools that add 1.0 for AP and IB classes report weighted GPAs on a 5.0 scale, so a student with straight As in all AP classes has a 5.0. Some districts add more than 1.0 or use a 6.0 or 12 point scale; pick the matching weighting rule above or compare the unweighted number, which is always on the 4.0 scale.

Both appear on your transcript and most admissions offices look at your course list alongside the numbers. Many colleges, including the University of California system, recalculate a GPA with their own weighting cap, so a high weighted GPA from a school that weights generously does not transfer one to one. Use the unweighted GPA to compare yourself with national averages and the weighted one to see the payoff of harder classes.

On the common scale with pluses and minuses, 93 to 100% is an A, so a 93 is a 4.0 unweighted, or 5.0 in an AP class. On a plain 10 point scale any 90 or above is an A. Schools on a 7 point scale also start an A at 93.

A 3.7 is an A- on the standard 4.0 scale, so it sits between a B+ (3.3) and an A (4.0). As an unweighted high school GPA it means mostly As with a few Bs, which is well above the 3.11 US average.
