How GPA is calculated
GPA (grade point average) is the credit-weighted average of your grade points on the US 4.0 scale. Each letter grade has a point value, and courses with more credits count for more. If your school or university uses a 10-point CGPA, use the CGPA to percentage calculator instead.
GPA formula
GPA = Σ (grade points × credits) ÷ Σ credits
Multiply each course's grade points by its credits, add these up, and divide by the total credits. An A is 4.0, B is 3.0, C is 2.0, D is 1.0 and F is 0; plus and minus grades add or subtract about 0.3.
Good to know
- Some US schools give A+ 4.3 instead of 4.0, and some high schools weight honours and AP courses more. Check your school's scale.
- Cumulative GPA averages every course you've taken, weighted by credits, not the average of semester GPAs.
- Indian SGPA and CGPA use a 10-point scale and can't be converted to a US GPA with a single formula. Universities abroad often use a credential evaluation service such as WES.
- The 'share of 4.0' result is just your GPA as a percentage of the maximum; it is not the same as a marks percentage.
Worked example
- Three courses: A in a 4-credit course, B+ in a 3-credit course and A− in a 3-credit course
- Points: 4.0 × 4 = 16, 3.3 × 3 = 9.9, 3.7 × 3 = 11.1
- Total: 37 points over 10 credits
- GPA = 37 ÷ 10 = 3.70
