How to Calculate GPA
On this page
Calculate GPA by converting each included grade to points, multiplying by its GPA credits, summing quality points, and dividing by total included GPA credits.
Direct answer
Calculate GPA by converting each included grade to points, multiplying by its GPA credits, summing quality points, and dividing by total included GPA credits.
Method and required inputs
Use GPA = Σ(grade points × course credits) / Σ(included course credits). Keep the grade scale, repeat treatment, pass/fail treatment, and honors rules beside the calculation.
Worked example
On an assumed scale A = 4.0, B+ = 3.3, A- = 3.7, B = 3.0: courses worth 3, 3, 4, and 2 credits contribute 12.0 + 9.9 + 14.8 + 6.0 = 42.7 quality points. GPA = 42.7 / 12 = 3.558, displayed as 3.56 if the policy rounds to two decimals.
Assumptions and limitations
The example scale and rounding are explicit assumptions. Official GPA may exclude courses, use different point values, cap honors credit, or retain more decimals.
Checks and common errors
- Reconcile credits with the transcript.
- Use the exact grade table.
- Round once at the end unless policy says otherwise.
Frequently asked questions
Why is my GPA not the average of my letter-grade point values?
Courses with more GPA credits contribute more weight, so a simple average works only when every included course has equal credit.
