A weighted GPA adds extra grade points for harder classes: usually 0.5 for honors and 1.0 for AP or IB, so an A in an AP class counts as 5.0 instead of 4.0. An AP A and a regular B, one credit each, give (5.0 + 3.0) ÷ 2 = 4.00 weighted and 3.50 unweighted.
High-school transcripts often report two GPAs, and students applying to college or for scholarships want to know both. This calculator takes one row per course with its letter grade, level and credits, then returns the weighted GPA on a 5.0 scale, the unweighted 4.0 figure and the difference the harder classes make. A table lists each course's weighted and quality points, and a bar chart compares the weighted points course by course. One limit: schools do not agree on bonuses. Some give AP only +0.5, some cap how many weighted courses count, and some colleges recalculate GPA with their own rules, so check your school's policy before quoting the number.
Type an optional course name, then pick the letter grade. Use Add course for more rows.
Choose Regular, Honors (+0.5) or AP / IB (+1.0) for each course.
Use 1 for a full-year class and 0.5 for a semester class, or your school's credit values.
Compare weighted and unweighted results, the per-course table and the bar chart, which you can download as PNG, SVG or CSV.
Result Weighted GPA: 4.00
Unweighted GPA: 3.5
Boost from course level: 0.5
Total credits: 2
Courses counted: 2
The AP course adds a full point to the A, so the weighted GPA reaches 4.00 while the unweighted GPA stays at 3.50.
Result Weighted GPA: 3.60
Unweighted GPA: 3.1
Boost from course level: 0.5
Total credits: 3

4.5 + 4.3 + 2.0 = 10.8 quality points over 3 credits gives 3.60 weighted, against 3.10 unweighted.
Result Weighted GPA: 4.40
Unweighted GPA: 3.6
Boost from course level: 0.8
Total credits: 2.5

A two-credit AP A counts four times as much as a half-credit elective: (5.0 × 2 + 2.0 × 0.5) ÷ 2.5 = 4.40.
weighted GPA = Σ (grade points + level bonus) × credits ÷ Σ credits
grade pointslevel bonuscreditsEach course's letter grade is converted to its 4.0-scale value, and the level bonus is added. Multiplying by credits gives quality points; their sum divided by total credits is the weighted GPA. The unweighted GPA repeats the sum without bonuses, and the boost is the gap between the two.
Yes. With a full point added for AP and IB classes, straight A grades in those courses give 5.0, so weighted figures between 4.0 and 5.0 are normal for students with many advanced classes.
Many admissions offices look at both, and a large number recalculate GPA themselves, often stripping out electives and applying their own weighting. Rigor of the course list is usually judged separately from the number.
Most schools that weight grades only add the bonus to passing grades, so a failed advanced course counts as 0 rather than 1.0. That keeps a failing grade from looking like a D.
Honors classes are school-designed advanced courses and commonly receive 0.5 extra points. AP and IB courses follow external curricula with exams and commonly receive 1.0. Some districts weight both equally.
On the standard 4.0 scale used here, A+ and A both convert to 4.0. A few schools give A+ a 4.3, which this calculator does not apply.
Enter the class with its real credit value, such as 0.5 for a single semester. The calculation weights each course by credits, so a half-credit class moves the GPA half as much as a full-year one.
