How does this calculator work?
GPA = sum of (grade points × credits) divided by total credits, all on a 4.0 scale. Add each course's letter grade and credit hours above; add your prior cumulative GPA and credits to get the updated overall. A heavier-credit course pulls the average more than a 1-credit elective.
Formula
How this is calculated
GPA (Grade Point Average) is calculated by multiplying each course's grade points by its credit hours, summing those quality points, and dividing by the total credit hours. On the standard US 4.0 scale, an A or A+ is worth 4.0, A- is 3.7, B+ is 3.3, and so on down to F = 0.0. A 3-credit course with a B (3.0) contributes 9 quality points; a 4-credit course with an A (4.0) contributes 16 — heavier courses pull your average more strongly.
Cumulative GPA works the same way but pools all semesters. The calculator lets you enter your prior cumulative GPA and prior credit total, then merges this semester's quality points with the previous total to give the updated cumulative. A single bad semester has less impact the more credits you already have banked.
Grading scales vary by institution: some schools award A+ = 4.0 (same as A), others use 4.3 or 4.33 for A+. This calculator uses the most common US 4.0 convention. Always verify against your own college's grading policy.
Frequently asked questions
Yes. GPA is credit-weighted, so a 4-credit course with an A contributes 16 quality points while a 1-credit course with an A contributes only 4. Taking more credits at a high grade is the fastest way to raise your GPA.
Because cumulative GPA is credit-weighted, recovering takes time. A single great semester barely moves a cumulative built over many prior credits. The formula is: new cumulative = (old GPA × old credits + new GPA × new credits) ÷ total credits.
Most graduate programs look for a 3.0 minimum (B average), with competitive programs expecting 3.5 or higher. Some schools also calculate a "major GPA" (only courses in your degree subject), which may matter more than the overall.
