GPA is total quality points divided by total credits, where quality points are credits times grade points (A = 4, B = 3, C = 2). An A in a 3-credit class, a B in a 4-credit class and a C in a 3-credit class give 30 points over 10 credits: a 3.00 GPA.
High-school students filling in applications, and anyone comparing a report card against a scholarship minimum, often need the same grades read two ways: unweighted on the plain 4.0 scale, and weighted with extra points for harder classes. Enter each class with its letter grade, credit value and level. The calculator gives the unweighted GPA as the headline, the weighted GPA beside it, the nearest letter grade, total credits and quality points, plus a per-class table and a bar chart of weighted points you can save as PNG, SVG or CSV. The honors and AP/IB bonuses used here (+0.5 and +1.0) are the most common, but districts set their own, so a transcript GPA can differ.
Give the class a name if you want, pick the letter grade, enter its credits and choose Regular, Honors or AP / IB. Use Add course for more rows.
Choose whether your school caps an A+ at 4.0 or counts it as 4.3.
The headline is unweighted; the weighted GPA, letter equivalent and quality points sit below, with the per-class table and chart.
Result Unweighted GPA: 3.00
Weighted GPA: 3
Letter equivalent: B
Total credits: 10
Quality points: 30
The four-credit B carries more weight than either three-credit class, so the GPA sits exactly at 3.00.
Result Unweighted GPA: 3.70
Weighted GPA: 4.49
Letter equivalent: A-
Total credits: 7
Quality points: 25.9
Unweighted, the pair averages 3.70. With +1.0 for AP and +0.5 for honors the weighted figure climbs to 4.49, above the 4.0 ceiling.
GPA = Σ(credits × grade points) ÷ Σ credits; weighted GPA adds the level bonus to each passing grade before multiplying
creditsgrade pointslevel bonusEach class contributes its credits multiplied by its grade points, called quality points. Dividing the sum by total credits gives a credit-weighted average, so a four-credit class moves the GPA more than a one-credit elective. The weighted version repeats the sum after adding the level bonus to each passing grade, which is why it can exceed 4.0.
Unweighted GPA treats every class on the same 0 to 4.0 scale. Weighted GPA adds points for difficulty, commonly 0.5 for honors and 1.0 for AP or IB, so an A in an AP class counts as 5.0 and the average can rise above 4.0.
Not here, and not at most schools. The bonus rewards passing work in a harder class, so an F stays at 0 points whether the class was regular, honors or AP.
Because the average is weighted by credits. A B in a 4-credit lab science pulls the GPA down more than a B in a 1-credit elective, since it contributes four times as many quality points.
It depends on the institution. Many high schools and colleges cap the A+ at 4.0, while some universities award 4.3. Pick the option your school's grading policy uses.
Admissions offices frequently recompute GPA from the transcript, counting only core academic classes such as English, maths, science, social studies and languages, and removing or capping the honors and AP bonus. That makes the unweighted figure the nearer match to what a reader sees.
The letter shown is the nearest step on the plus/minus scale: for example 3.65 sits closer to A- (3.7) than to B+ (3.3), so it reads as A-.
