Formula: GPA = (Σ (Grade Point × Credits)) / Total Credits. Standard weights: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0.
Grade Point Average (GPA) is a standard metric used by schools, colleges, and universities to measure overall academic achievement.
The GPA Calculator helps you compute either a single semester GPA or a cumulative GPA. It maps traditional letter grades (A, B, C, D, F) to standard grade points (4.0, 3.0, 2.0, 1.0, 0.0) and weights them by credit hours.
Because credits vary between lectures and lab sessions, using a credit-weighted average ensures your GPA correctly reflects the academic weight of each course.
Our simple interface allows you to add multiple courses, choose their credit hours, assign letter grades, and see the final calculated GPA instantly.

Answers to help you use the calculator correctly.
Most US institutions use a standard 4.0 scale, where: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0.
Yes, in many schools: A- is 3.7, B+ is 3.3, B- is 2.7, C+ is 2.3, etc. This calculator uses standard weights (A=4, B=3, C=2, D=1, F=0) for maximum compatibility.
Pass/fail courses typically do not calculate into your GPA. You should omit them from this calculator.
