How to calculate your GPA on a 4.0, 4.3 or 4.5 scale

Short answer: GPA = sum of (grade points × credits) ÷ total credits.

1. Turn each letter into grade points

On a 4.0 scale with +/-: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, C = 2.0. On a 4.3 scale A+ = 4.3. On a 4.5 scale (common in Korea) A+ = 4.5, A0 = 4.0, B+ = 3.5.

2. Multiply by credits

Biology A− (3 credits) = 11.1, Statistics A (3) = 12.0, History C (3) = 6.0, Spanish A− (3) = 11.1, Programming A− (3) = 11.1.

3. Add and divide

51.3 ÷ 15 credits = 3.42 term GPA.

4. Cumulative GPA

Do the same with every class from every term: add all grade points × credits and divide by all credits. Don't average the term GPAs — terms with more credits count more.

How Gradora helps

Pick your school's scale once (4.0 with +/-, 4.0 simple, 4.3 or 4.5). Current classes turn into letters automatically, past courses only need a letter and credits, and the GPA tab shows term and cumulative GPA side by side.

FAQ

What is the difference between term and cumulative GPA?

Term GPA uses only this term's classes. Cumulative GPA uses every graded class so far, weighted by credits.

Does an A+ count as more than 4.0?

On a 4.3 scale yes (A+ = 4.3). On a 4.0 scale A+ usually counts as 4.0. Check your school's scale.

Do pass/fail classes count?

Usually not. Leave them out of both the points and the credits.
