A GPA is not a simple average of grades — it is a credit-weighted average. First convert each course grade to grade points on the standard 4.0 scale used here: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0. Then multiply each course's points by its credits, add them all up for total grade points, and divide by the total credits that count toward GPA — that is the semester GPA. The default example has four courses: A (3 credits), B+ (3 credits), A- (4 credits) and B (3 credits), giving 45.7 grade points over 13 credits, so 45.7 / 13 = 3.52. Credits are the weights, so a 4-credit A- (14.8 points) moves the total more than a 3-credit B (9.0 points); averaging the letter grades alone, without credits, gives the wrong answer.

Three uses cover most students. First, checking a cutoff: many scholarships and programs require a 3.50 semester GPA, and the default example at 3.52 just clears it — but swap one B+ for a B and total points fall to 44.8, semester GPA to 3.45, below the line. Half a grade step in one course can decide the outcome, so confirm first whether the cutoff looks at semester GPA or cumulative GPA. Second, planning cumulative GPA: a prior record of 30 credits at 3.40 (102 points) plus the default semester's 45.7 points over 13 credits gives 147.7 points over 43 credits, a cumulative GPA of 147.7 / 43 = 3.43. Worked backwards, lifting cumulative GPA from 3.43 to 3.50 over a 15-credit next semester requires a 3.69 semester GPA — a concrete target rather than a vague aim to do better. Third, checking a transcript: enter every course line by line and compare total credits and total points against the transcript, which catches the small errors — a mistyped credit value, a grade read from the wrong row — before they turn into a dispute.

A few edge cases deserve a clear statement. First, pass grades are excluded: a course taken pass or fail, entered here as P, adds nothing to total grade points and nothing to total credits — an A (3 credits) plus a P course (2 credits) still gives 12 / 3 = 4.00, neither diluted nor lifted. Second, failing grades count at zero but keep their credits: an A (3 credits) plus an F (3 credits) gives 12 points over 6 credits, a GPA of 2.00, and retake rules are left to your school — this page calculates from the transcript exactly as entered. Third, grade scales are not universal: some schools have no plus or minus grades, some count A- as 3.67, some count A+ as 4.33, so if your school's scale differs, this result is a reference and the registrar's figure is official. Fourth, input limits: each course must carry more than 0 and at most 20 credits, prior cumulative GPA must sit between 0 and 4.00, prior credits must be greater than 0, and the two prior fields are either both filled or both blank; with only pass courses, or no courses at all, the page says a countable course is missing instead of inventing a number. Fifth, GPAs display to two decimal places while the calculation keeps unrounded values and rounds only at the final step, so recomputing from the displayed values can differ by 0.01 — a rounding difference, not an error.

Using it is straightforward: enter prior cumulative GPA and credits at the top (leave both blank if you have none), then add courses row by row with a grade and credits — add a row for a new course, delete a row to remove one. Semester GPA, cumulative GPA, total grade points and total credits recalculate as you type. Copy the result to check it with an advisor or a classmate, or reset to return to the example. Everything is calculated in your browser — the grades and credits you enter are never uploaded, and no account is needed.
