How to Calculate GPA on a 4.0 Scale
Step 1: grade points
On the common 4.0 scale: 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, F = 0. Check your own school, since some differ.
Step 2: weight by credits
Multiply each grade-point value by the course’s credits to get quality points. A 4-credit B is worth more than a 1-credit B.
Step 3: divide
Divide total quality points by total credits. Four courses with different credits give GPA 3.36.
Four courses
- 12 credits
- 40.3 quality points
Step-by-step working 3 steps
- 1Convert each grade to grade points (4.0 scale)
A (4.0) × 3 credits = 12 B+ (3.3) × 4 credits = 13.2 A- (3.7) × 3 credits = 11.1 C (2.0) × 2 credits = 4
Scale used: A/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. Schools differ — check yours.
- 2Add quality points and credits
Quality points = 40.3 Credits = 12
- 3GPA = quality points ÷ credits
40.3 ÷ 12 = 3.3583
Planning ahead
Change one grade in the calculator to see how much a single course moves your GPA. Higher-credit courses move it most.
Common mistakes
Averaging grades without credits
Credits weight each course.
Using the wrong scale
Check whether your school gives A+ extra points.
Including pass/fail courses
Most schools exclude them.
