How it works
A GPA calculator converts the letter grades from your courses into a single grade point average on the familiar 4.0 scale. Each letter maps to a point value — A is 4.0, B is 3.0, C is 2.0, with plus and minus modifiers in between — and every course is weighted by its credit hours before being averaged. The result is the number that appears on transcripts and that schools, scholarships and employers read at a glance. Weighting by credit hours is the crucial step. A four-credit course shapes your standing more than a one-credit elective, and a plain average of letters would ignore that. A GPA calculator multiplies each grade's points by its credits so a heavier course pulls proportionally harder, exactly as a registrar computes it. The multiply-by-credits-then-divide method is the standard 4.0 scale used across United States high schools and colleges. Students use a GPA calculator to track their average across a term or a whole degree, project how a coming semester will move it, and see what grades they need to reach a target for graduate school or a scholarship. Enter your grades and credit hours and it returns the GPA, total credits and course count in one pass; leave credits blank and each course counts equally.
GPA = Σ(grade points × credits) ÷ Σ(credits)
Each letter grade becomes a point value on the 4.0 scale, then is multiplied by the course's credit hours so weightier courses carry more influence. Summing those grade-point-times-credit products gives the total quality points earned. Dividing by the total credits attempted rescales that back onto the 0 to 4.0 range, which is why a high grade in a large course lifts the average more than the same grade in a small one.

Frequently asked questions
What grade scale does this GPA calculator use?
It applies the standard United States 4.0 scale with plus and minus modifiers: A is 4.0, A minus 3.7, B plus 3.3, B 3.0, and so on down to F at 0.0. This is the most widely recognised system across American colleges and high schools. Some institutions treat an A plus as 4.0 rather than 4.3, or cap the scale differently, so check your school's official conversion chart if your transcript looks slightly different.
What is a good GPA?
A 3.0 sits at a solid B average and is a common baseline for many programmes and employers. A 3.5 and above is generally considered strong and opens doors to competitive scholarships and graduate schools, while 3.7 or higher is excellent. Standards vary by context — some selective programmes expect close to 4.0, whereas passing a demanding degree may only require 2.0. Judge your number against the specific goal you are aiming for.
How do credit hours affect my GPA?
Credit hours weight each course's influence on the average. A four-credit course counts four times as heavily as a one-credit course, so a strong grade in a large class lifts your GPA more, and a weak one drags it down further. Enter credits in the same order as your grades for an accurate result. Leave them blank and the tool assumes one credit each, giving every course equal weight.
How do I calculate a cumulative GPA across semesters?
Enter every course from all the semesters you want to include, each with its own grade and credit hours, and the tool returns your cumulative GPA in one calculation. Alternatively, combine the total quality points and total credits from each term and divide. Do not simply average your semester GPAs together — that ignores how many credits each term carried and produces a subtly wrong cumulative figure that will not match your transcript.
Does this calculate a weighted honors GPA?
No. This tool uses the unweighted 4.0 scale, where an A is 4.0 regardless of course difficulty. Weighted systems add extra points for honors, Advanced Placement or International Baccalaureate classes — often putting an A at 4.5 or 5.0 — but the bonus and the cap vary widely between schools. Because there is no single standard, calculate a weighted GPA using your own school's specific point additions rather than assuming a universal rule.
