CGPA calculator
Calculate your CGPA on the 10-point scale used by Indian universities.
CGPA (10-point)
CGPA on the 10-point scale
Indian universities grade on a 10-point scale, where each letter grade maps to a grade point: O = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P = 4, and below that is a fail. Your CGPA is the average of those grade points across every course, weighted by each course's credits — switch the scale selector to India 10.0, enter your courses, and the dial shows your CGPA out of 10 as you type.
How CGPA is calculated
CGPA is a credit-weighted average, not a plain average. Each course's grade point is multiplied by its credits, you add those products up, and divide by total credits:
CGPA = Σ(grade point × credits) ÷ Σ(credits)
Worked example
Say one semester looks like this:
- Mathematics — 4 credits, grade A+ (9)
- Physics — 3 credits, grade A (8)
- Chemistry — 3 credits, grade B+ (7)
- English — 2 credits, grade O (10)
Weighted points = (9×4) + (8×3) + (7×3) + (10×2) = 36 + 24 + 21 + 20 = 101. Total credits = 4 + 3 + 3 + 2 = 12. CGPA = 101 ÷ 12 = 8.42. Notice the 4-credit A+ pulls the average up more than the 2-credit O, because credits decide how much each grade counts.
Common mistakes to avoid
- Averaging the grade points directly (9+8+7+10 ÷ 4 = 8.5) ignores credits and gives the wrong answer. Always weight by credits.
- Mixing SGPA and CGPA. SGPA is one semester; CGPA is all semesters combined. Don't average your SGPAs unless every semester carried equal credits.
- Using the wrong grade-point scale. A few universities cap at 9 or use a 4-point system — check your grade card before assuming O = 10.
