Find your school’s GPA scale (e.g., 4.0, 5.0) and grading policy (letter grades to grade points).
Collect your final grades for all completed courses.
Verify which courses count toward GPA (exclude withdrawals, audited courses, or non-graded credits if applicable).
For each course, record the credit hours and the grade earned.
Convert each letter grade (or percent grade) to the corresponding grade points using your school’s conversion table.
Multiply each course’s grade points by its credit hours.
Add all the resulting values to get total quality points.
Add all the credit hours that count toward GPA to get total attempted (or counted) credits.
Calculate GPA as: total quality points ÷ total counted credit hours.
If your school uses weighted GPA, apply the weighting rules for honors/AP/IB or other designated courses.
If your school reports multiple GPAs (cumulative vs term, weighted vs unweighted), repeat the calculation for the specific period.
Use your student portal/transcript GPA calculator if available and confirm it matches your counted courses.
Double-check rounding rules (e.g., to two decimal places) before finalizing.
