Subjects
What these mean:
Your credit-weighted CGPA across 5 subjects (16 credits) is 8 on the 10-point scale — each subject's grade point is weighted by its credits, not a plain average.

How CGPA is calculated
CGPA is the credit-weightedaverage of your subject grade points on the 10-point scale. Each subject's grade point is multiplied by its credits, the products are summed, and the total is divided by the total credits — so high-credit courses count for more than a plain average would give them.
Credit-weighted
Σ(credits × GP) ÷ Σ(credits)
CGPA = Σ(credits × grade point) ÷ Σ(credits)
A 4-credit 9 outweighs a 2-credit 6 — exactly as it should.

Enter each subject's grade point; a failed/arrear subject is 0.
- 1Weight each subject by its credits: 4×9 + 4×8 + 3×7 + 3×9 + 2×6 = 36 + 32 + 21 + 27 + 12 = 128 grade points over 16 credits → 128 ÷ 16 = 8.00.

SGPA vs CGPA & how arrears count
SGPA is the credit-weighted average for one semester; CGPAis the cumulative figure across all semesters. Entering every subject here gives the same result as rolling up each semester's SGPA.
An arrear counts as 0 — but its credits stay
Credit-weighting rewards your heavy courses
Frequently asked questions
CGPA (Cumulative Grade Point Average) is a single number that summarises your academic performance across all subjects. On the Indian 10-point scale used by most universities and CBSE, it is the credit-weighted average of your subject grade points: multiply each subject’s grade point by its credits, add them up, and divide by the total credits. A CGPA of 8.0 means you averaged an 8 grade point across everything, weighted by how many credits each course carried.
Because not every course is worth the same. A 4-credit core subject should move your CGPA more than a 1-credit lab or seminar. Credit-weighting handles this: CGPA = Σ(credits × grade point) ÷ Σ(credits). If you scored a 9 in a 4-credit course and a 6 in a 2-credit course, the 9 counts twice as heavily as the 6 — a plain average would wrongly treat them equally.
SGPA (Semester Grade Point Average) is the credit-weighted grade point average for a single semester. CGPA is the cumulative figure across all semesters completed so far. You can roll up per-semester SGPAs into an overall CGPA by credit-weighting each semester’s SGPA — the SGPA to CGPA Calculator does exactly that. This CGPA calculator works at the subject level, which gives the same result when you enter every subject.
A failed or arrear subject is recorded as 0 grade points, but its credits still count in the denominator. So it pulls your CGPA down twice as hard as a low pass: you gain 0 grade points on credits that still inflate the total. Once you clear the arrear, re-enter the subject with its new grade point and the CGPA recovers. In this tool, set an arrear subject’s grade point to 0 and keep its real credits.
There is no single universal formula — each university defines its own. A common CBSE/informal rule multiplies CGPA by 9.5 (so 8.0 CGPA ≈ 76%), but VTU, Mumbai University, Anna University, JNTU and others each publish their own conversion (affine or piecewise) formula. Use the CGPA to Percentage Calculator and pick your university to get the officially correct figure rather than a rough ×9.5 estimate.

Method, assumptions & references
Methodology: CGPA = Σ(credits × grade point) ÷ Σ(credits) on the 10-point scale. A failed/arrear subject contributes 0 grade points but its credits remain in the total. All calculations run client-side; nothing is stored. To convert CGPA to a percentage, use your university's official formula rather than a rough ×9.5 estimate.
