How this calculation works
Each grade converts to grade points on a 4.0 scale (A = 4.0 down to F = 0.0). GPA is the credit-weighted average: multiply each course’s grade points by its credit hours, add those up, then divide by the total credit hours — so a 4-credit course counts twice as much as a 2-credit course.
Worked example
One 4-credit A (4.0), one 3-credit B (3.0) and one 3-credit C (2.0): (4×4.0 + 3×3.0 + 3×2.0) ÷ (4+3+3) = 31 ÷ 10 = 3.1 GPA.
Tips
Leave unused rows blank
Rows with no credit hours entered are simply skipped, so you don't need exactly five courses to get an accurate GPA.
This is an unweighted 4.0 scale
Some schools give extra points for honours or AP classes. If yours does, your official GPA may be higher than the result here.

Credit hours change the weight
A grade in a 4-credit course moves your GPA twice as much as the same grade in a 2-credit course.
Frequently asked questions
What scale does this use?
A standard 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 = 0.0.
Does my school use the same scale?
Grading scales vary between institutions — check your school's official scale if you need an exact, transcript-matching GPA.
