This GPA calculator uses course grades and credit hours to calculate a credit-weighted result. Choose the grade scale that matches your school, then check the total quality points, credits counted, and per-course breakdown.
How to use the GPA calculator
Use this when you have individual course grades and credits for one term or set of courses. To combine already-reported term GPAs, use the cumulative GPA calculator; for course-level weighting, use the high-school GPA calculator.
A four-credit course affects the GPA four times as much as a one-credit course.
Use the Grade scale control to switch between plus/minus and whole-letter grades. When plus/minus is selected, use the A+ value control to match your school's policy.
For P/NP/I/W or another transcript mark, follow your school's policy instead of entering it in this calculator.
Example: three courses with different credits
- For an A worth 3 credits, a B+ worth 4 credits, and an A− worth 2 credits, the calculator totals 32.60 quality points across 9 credits.
- The credit-weighted GPA is 3.62.
How GPA is calculated
Each letter grade is converted to grade points. Grade points are multiplied by course credits to get quality points, and total quality points are divided by total GPA-bearing credits.
Why a plain grade average can be wrong
Courses with different credit hours do not carry equal weight. Averaging the grade-point values directly gives the wrong answer whenever the credit loads differ.
