Universities in the US and many international programmes report a GPA on a 4.0 scale. Enter your letter grades and the credit hours for each course to see your GPA and every step of the calculation.
Type your letter grades separated by commas.
Enter credit hours for each course in the same order.

GPA: GPA = Σ(grade points × credits) ÷ Σ credits
This GPA calculator works on the 4.0 scale used by universities in the United States and many international programmes. You type letter grades such as A, B+ or C-, add the credit hours of each course, and it converts the letters to grade points and computes the credit-weighted GPA.
Indian students meet the 4.0 scale when applying to universities abroad, when studying in international schools or exchange programmes, and when evaluation agencies ask for a GPA. Knowing how letters turn into points helps you read a foreign transcript and estimate where you stand.
The mapping used here is the common unweighted one: A+ and A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, down to D = 1.0 and F = 0. Some institutions use slightly different values, so check your own scale.
1. List each course with its letter grade and credit hours.
2. Convert letters to points: 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, F 0.
3. Multiply points × credit hours for each course to get quality points.
4. Add all quality points.
5. Add all credit hours.
6. Compute GPA = total quality points ÷ total credit hours, rounded to two decimals.
On the standard scale each letter is a whole point apart, and a plus or minus shifts the value by about a third of a point. So B+ is 3.3, a third above B, and A- is 3.7, a third below A. Most schools cap A+ at 4.0 so the scale tops out cleanly; a few give 4.3. Because the steps are small, a transcript full of B+ and A- grades lands between 3.3 and 3.7, which is why GPAs often cluster there.
The term 'quality points' is simply grade points multiplied by credit hours. A 4-credit A contributes 16 quality points, while a 2-credit A contributes 8. Dividing total quality points by total credits gives the average grade per credit hour. This is the same weighted-mean logic as an Indian SGPA, just on a 4-point scale with letter inputs. Courses taken pass/fail usually carry credits toward graduation but are left out of the GPA.
Dividing a 10-point CGPA by 2.5 gives a number on a 4-point scale, but universities and evaluation agencies do not accept that shortcut. Agencies such as WES convert each subject grade separately using their own tables for each Indian university, so the result depends on individual marks. This calculator does not convert Indian grades; it works from letter grades you already have. For applications, quote the grades on your transcript and let the institution convert.
Aditi is on a semester exchange in the US and received A in a 4-credit course, A- and B+ in two 3-credit courses, B in another 3-credit course and C+ in a 2-credit elective.
Convert letters to grade points: A = 4, A- = 3.7, B+ = 3.3, B = 3, C+ = 2.3
Multiply each grade point by its credits: 4 × 4 = 16 3.7 × 3 = 11.1 3.3 × 3 = 9.9 3 × 3 = 9 2.3 × 2 = 4.6
Add the products (credit points): 16 + 11.1 + 9.9 + 9 + 4.6 = 50.6
Add the credits: 4 + 3 + 3 + 3 + 2 = 15
GPA = total quality points ÷ total credits: 50.6 ÷ 15 = 3.37
Answer: GPA (4.0 scale) 3.37; Total credits 15

Is an A+ worth more than 4.0?
On the standard unweighted scale used here, A+ and A are both 4.0. Some schools use 4.3 for A+; check your institution.
Can I convert Indian CGPA to a 4.0 GPA?
There is no official formula; agencies such as WES convert course by course. Use your transcript's grades where possible.
