An unweighted GPA converts each letter grade to points on a 4.0 scale (A = 4, B = 3, C = 2, D = 1, F = 0), multiplies by the course credits and divides by total credits. Honors and AP classes get no extra point. An A, a B and a C in equal-credit classes give (4 + 3 + 2) ÷ 3 = 3.00.
Colleges, scholarship forms and many high school transcripts ask for an unweighted GPA so that students from schools with different honors policies can be compared on one 4.0 scale. Enter one row per course with its letter grade and credits; the result shows your GPA to two decimals, the closest letter, total quality points and a table of what each class contributed. A bar chart shows how many credits sit in each letter band. The point values follow the common plus/minus scale (A- = 3.7, B+ = 3.3), but some schools count A+ as 4.3 or drop minuses entirely, so check your own handbook before quoting the number on an application.
Type the course name if you like, then pick its letter grade. Use Add course for more classes.
Put the credit hours or units for each class. Leave it at 1 when all classes count equally.
The GPA, letter equivalent and quality points update as you type, and the table lists the points each course earned.
Result Unweighted GPA (4.0 scale): 3.00
Letter equivalent: B
Total credits: 3
Quality points: 9
Share of a perfect 4.0: 75%
Three equal-credit classes average to exactly 3.00, the middle of the B range.
Result Unweighted GPA (4.0 scale): 3.59
Letter equivalent: A-
Total credits: 8
Quality points: 28.7
Share of a perfect 4.0: 89.7%
14.8 + 9.9 + 4.0 = 28.7 quality points over 8 credits gives 3.59; the A- lab counts four times as much as gym.
Result Unweighted GPA (4.0 scale): 0.50
Letter equivalent: D-
Total credits: 2
Quality points: 1
Share of a perfect 4.0: 12.5%
One D and one failing grade average to 0.50, well under the 2.0 line many schools use.
GPA = Σ(grade points × credits) ÷ Σ credits
grade pointscreditsEach letter grade is mapped to a fixed point value with no bonus for honors, AP or IB level. Multiplying by credits gives the course's quality points; the sum of quality points divided by the sum of credits is the unweighted GPA. The letter equivalent picks the nearest letter on the same scale, so 3.59 reads as A-.
An unweighted GPA treats every class the same, so an A is 4.0 whether it came from regular English or AP Calculus. A weighted GPA adds a bonus, often 0.5 or 1.0, for harder classes, which is why weighted figures can exceed 4.0.
A 3.5 sits between B+ and A-, about 87.5% of a perfect 4.0. Many selective colleges report admitted-student averages above 3.7 unweighted, while a 3.0 is a common floor for scholarships.
On the standard unweighted scale used by the College Board and most US high schools, 4.0 is the ceiling. A few schools award 4.3 for an A+, but colleges recalculating your GPA normally cap it at 4.0.
Most schools map 93–100 to A, 90–92 to A-, 87–89 to B+ and so on down to F below 60 or 65. Convert each percentage to its letter using your school's chart, then choose that letter in the row.
Yes. Add every graded course from all the semesters you want to include with its credits; the result is a cumulative unweighted GPA over those terms.
Quality points are grade points multiplied by credits. A B+ in a 3-credit class earns 3.3 × 3 = 9.9 quality points. Dividing total quality points by total credits gives the GPA.
