About this calculator
College GPA on the 4.0 scale: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, etc. F=0. Quality points = credits × grade points; GPA = total quality points / total credits. Latin honors thresholds: cum laude 3.5, magna 3.7, summa 3.9 (school-specific exact cutoffs vary).
How it works — the formula
GPA = Σ (course_GPA × credit_hours) / Σ (credit_hours)
4.0 scale: A=4, B=3, C=2, D=1, F=0 (with ± fractions in many systems)College GPA is a credit-weighted mean of per-course quality points. Each letter grade maps to a numeric value on a fixed scale (4.0 in the US standard, 4.5 or 5.0 in some weighted systems), and each course's contribution is scaled by its credit hours so that a 4-credit course counts twice as much as a 2-credit course. Plus/minus modifiers (B+ = 3.3, B− = 2.7) are common but vary by institution; the unmodified A=4/B=3/C=2/D=1/F=0 mapping is the lowest-common-denominator default per the AACRAO Academic Record and Transcript Guide.
Worked examples
- Inputs:
- 4 courses × 3 credits each: A, A−, B+, B
- Output:
- GPA = (4·3 + 3.7·3 + 3.3·3 + 3·3) / 12 = 3.5
- Inputs:
- 4-cr A (4.0), 3-cr B (3.0), 1-cr C (2.0)
- Output:
- GPA = (16 + 9 + 2) / 8 = 3.375
- Inputs:
- A in honors course (5.0 scale)
- Output:
- Adds 5.0 quality points per credit instead of 4.0; GPA can exceed 4.0
Limitations
- Schools differ on whether F counts toward the credit total in the denominator (most do).
- Withdrawn (W), Incomplete (I), and Pass/Fail courses generally do NOT contribute to GPA but still appear on the transcript.
- Repeating a course replaces the original grade in some systems and averages the two in others.
- International grade conversion is highly institution-specific — World Education Services (WES) and ECE produce certified equivalency reports.
GPA computation rules vary by institution. This calculator uses the standard 4.0 scale; check your school's academic catalog for any local exceptions before using the result for satisfactory-academic-progress decisions.
