GPA Calculator
Free GPA calculator. Enter each course's letter grade and credit hours to compute your grade point average on the standard 4.0 scale, updated live.
Your grade point average rolls every course into a single number, weighted by how many credit hours each one carries. This GPA calculator does the math on the standard 4.0 scale: pick a letter grade for each course, enter its credit hours, and your GPA and total credits update instantly.
Because heavier courses pull harder on your average, simply averaging your letter grades won't match your official GPA — the credit weighting matters. Add your full schedule to see your term GPA, or enter past courses to track your cumulative standing. It all runs in your browser.
Frequently asked questions
How is GPA calculated?
Each letter grade maps to grade points (A = 4.0, B = 3.0, and so on). Multiply each course's points by its credit hours, sum those, and divide by the total credit hours.
What grade points does each letter use?
A+ and 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.
Why isn't my GPA the same as the average of my grades?
GPA is weighted by credit hours, so courses worth more credits count more. A high grade in a 4-credit course moves your GPA more than the same grade in a 1-credit course.
