GPA calculators that show their work.
Most free GPA calculators hand you a number with no way to tell how they got it. Change one setting and the answer moves, and nothing on the page says which convention was applied or why. These do the opposite: each shows the grade table it used, the credits it counted, and how much every individual course moved your average.

GradeCalculatorHQ makes the rules visible, handles common grading edge cases explicitly, and tells you when your school's own policy matters.
The rules are visible
Grade values and weighting policies are published on our methodology page and come from the same calculation rules used by the calculators. You can see the assumptions instead of taking the number on faith.
See how we calculateSpecial grades are handled
P, NP, W, and other non-graded statuses aren't quietly turned into failing grades. GradeCalculatorHQ follows the exact exclusion rules used by each calculator and explains where institutional policies can differ.
Your grades stay on device
The calculators are designed to run locally in your browser without requiring an account. Your grade entries are saved to your device and are never transmitted to our servers.
Your school has final say
A+ treatment, advanced-course weighting, percentage cutoffs, and other grading policies vary by institution. GradeCalculatorHQ makes those assumptions visible rather than pretending there is one universal grading system.
Your transcript remains the authority.
