Your cumulative GPA rolls up every course you've entered. We sum quality points and credits so you always see the real overall number.
See how each term landed before it blends into your cumulative average. Add semesters, plug in grades and credits, get an instant semester GPA.
Whether you're checking a high school transcript or a university semester — this runs on the standard 4.0 grading scale.
Pluses and minuses sit between whole steps — A- is 3.7, B+ is 3.3.

Adds bonus points for advanced coursework. Turn on the weighted toggle and mark honors (+0.5) or AP/IB (+1.0). The cumulative gauge switches to a 5.0 scale when any semester uses weighting.
The running average on most transcripts. Stack semester blocks to mirror your real course history and get an accurate cumulative number without doing the math yourself.
Quick benchmark: divide your GPA by 4 and multiply by 100. A 3.0 ≈ 75%. Always double-check with your school's conversion policy before using it on anything official.

Add each class with its letter grade and credit hours. Half credits (0.5) work too if your school uses them.
Turn on the weighted toggle for honors, AP, or IB. Regular classes stay on 4.0; weighted ones can hit up to 5.0.
Each semester block shows its own GPA — grade points divided by credits for that term only.
The big circle is your overall GPA across every semester you entered. That's the number on most transcripts.
The math: GPA = quality points ÷ credits.
Multiply each course's grade points by its credit hours to get quality points. Add them up, divide by total credits, round to two decimals. This calculator does that automatically — no spreadsheet required.
Unweighted GPA uses the standard 4.0 scale for every class. Weighted GPA adds extra points for advanced courses — typically +0.5 for honors and +1.0 for AP or IB — so strong students in hard classes can go above 4.0 on a 5.0 scale.
Cumulative GPA is total quality points from every completed course divided by total credit hours. Add all semesters together — don't just average semester GPAs, because terms with more credits should count more.
The 4.0 scale maps letter grades to points: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0, with pluses and minuses in between. Most U.S. high schools and colleges report GPA this way.
Rough rule on a 4.0 scale: percentage ≈ (GPA ÷ 4.0) × 100. So a 3.5 GPA is about 87.5%. Schools differ though — check with your registrar before using a converted number officially.
List every class from each semester with its letter grade and credits — core, electives, all of it. If your school weights honors/AP, mark those courses. Colleges usually care most about your cumulative GPA.
Most colleges review cumulative GPA on your transcript, often recalculating core academic courses. Weighted GPA shows rigor, but many admissions offices also look at unweighted GPA and how hard your schedule was.
You can average letter grades, but it's less accurate. A 4-credit class should pull your GPA more than a 1-credit class. That's why this calculator asks for credits.
