Grade & GPA Calculator

Grade Point Average (GPA) Calculator

Grade Point Average (GPA) is a standard metric used to evaluate a student’s academic performance. It represents the weighted average of grades earned across all courses, based on credit hours.

This calculator supports letter grades and numerical scores, converting them into grade points using a commonly accepted U.S. grading scale.

Letter Grade to Grade Point Scale

A+ = 4.3 | 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 | D− = 0.7
F = 0.0

Grades such as Pass (P), Not Pass (NP), Incomplete (I), and Withdrawal (W) are excluded from GPA calculations.

How Course Credits Affect GPA

Each course is assigned a credit value, which determines its weight in GPA calculation. Higher-credit courses have a greater impact on the final GPA.

Example: GPA Using Letter Grades

Math (4 credits): A+ → 4 × 4.3 = 17.2
Physics (2 credits): B → 2 × 3.0 = 6.0
English (3 credits): A → 3 × 4.0 = 12.0

Total Grade Points = 35.2
Total Credits = 9
GPA = 3.91

Example: GPA Using Numeric Grades

Biology (4 credits): 3 → 4 × 3 = 12
Chemistry (3 credits): 2 → 3 × 2 = 6
Chemistry Lab (2 credits): 4 → 2 × 4 = 8

Total Grade Points = 26
Total Credits = 9
GPA = 2.89

Attend Classes Actively

Regular attendance improves understanding, increases engagement, and helps clarify doubts. Professors are more likely to support attentive and involved students.

Plan and Manage Your Time

Effective scheduling, organized notes, and consistent review over time are far more effective than last-minute studying.
