4.0 scale. Leave unused rows empty.
How the GPA Calculator works
Each letter grade is turned into grade points (A = 4.0, A- = 3.7, B+ = 3.3 and so on), multiplied by the credit hours of that class to get quality points, and the total quality points are divided by the total credit hours. Classes with more credits count more.
Step-by-step calculation
- 1Enter each class's letter grade and credits.
- 2Convert grades to points.
- 3Multiply points by credits.
- 4Divide total points by total credits.
Worked example
A (4.0) in a 3-credit class, B+ (3.3) in a 4-credit class and B (3.0) in a 3-credit class: (12 + 13.2 + 9) รท 10 = 3.42 GPA.

Frequently asked questions
Does an A+ count as 4.3?
Most schools cap A+ at 4.0, so this calculator does too. If your school uses 4.3 for A+, your real GPA may be slightly higher.
Can I calculate a cumulative GPA?
Yes. Enter every class from all semesters, or enter your previous GPA as one row using your total earned credits.
What about pass/fail classes?
Pass/fail classes usually do not affect GPA, so leave them out.
