How GPA is Calculated

GPA (Grade Point Average) on the standard 4.0 scale is a credit-weighted average — courses worth more credit hours count more toward your final GPA than courses worth fewer.

Step 1: Convert each letter grade to grade points

GradePointsGradePoints
A+4.0C+2.3
A4.0C2.0
A-3.7C-1.7
B+3.3D+1.3
B3.0D1.0
B-2.7F0.0

Step 2: Weight by credit hours

GPA = Σ (Grade Points × Credit Hours) ÷ Σ (Credit Hours)

Multiply each course's grade point by its credit hours to get "quality points", add every course's quality points together, then divide by total credit hours.

Semester GPA vs cumulative GPA

Enter only this term's courses for a semester GPA, or every course you've taken across all terms for a cumulative GPA — the formula is identical either way, since it's just a weighted average over whichever set of courses you include.

For example, an A (4.0) in a 4-credit course and a B+ (3.3) in a 3-credit course gives (4.0×4 + 3.3×3) ÷ (4+3) = 25.9 ÷ 7 = 3.70 GPA. Enter these same figures into the calculator above to reproduce this result.

Frequently Asked Questions

Each letter grade converts to a grade point (A=4.0, A-=3.7, B+=3.3, and so on down to F=0.0). GPA is the credit-weighted average of those grade points: multiply each course's grade point by its credit hours, add them up, then divide by the total credit hours.

Semester GPA covers only the courses taken in one term. Cumulative GPA covers every course taken so far across all terms, weighted by each course's credit hours. Add all your courses from every semester into this calculator at once to get a cumulative figure, or just one semester's courses for a semester GPA.

No. The 4.0 scale (with A=4.0) is the most common convention at US and many international universities, but some use a 4.3 or 4.5 scale with an A+ above 4.0, and grading boundaries for B+, C+ etc. can differ slightly by institution. Check your university's official grade-point table if you need an exact match to your transcript.

At most universities, Pass/Fail (or Credit/No Credit) courses are excluded from GPA calculation entirely — they count toward your credit total for graduation but don't have a grade point. Leave Pass/Fail courses out of this calculator rather than assigning them a letter grade.

A 3.5+ GPA is generally considered strong and is often the cutoff for Latin honors like cum laude at many universities, 3.0+ is solid and typically the minimum for many graduate program applications, and below 2.0 often triggers academic probation. Requirements vary significantly by institution and program, so check specific cutoffs where they matter to you.

Because GPA is credit-weighted, improving grades in higher-credit courses moves your GPA more than the same grade change in a low-credit course. Use this calculator to test scenarios — swap a grade or add a hypothetical future course's expected grade and credits to see the projected effect before you register or study for a final.
