University rule guide
Anna University GPA and CGPA calculator guide
The regulation-aware GPA tool covers B.E./B.Tech. students in Anna University affiliated non-autonomous institutions under R2025 and R2021. University Departments and autonomous colleges can follow different regulations; the generic CGPA/target arithmetic is safe only when you enter the official GPA and counted credits from your own regulation.
Programmes and regulations covered
University Departments at CEG, ACT, MIT and SAP; Anna University managed institutions; affiliated colleges across Tamil Nadu. The calculator scope is set by programme and regulation, not by the university name alone.
Academic Regulations 2025 · B.E./B.Tech. Affiliated
Scope: B.E./B.Tech. students admitted from academic year 2025-26 in affiliated non-autonomous institutions
Uses absolute grading. The standard course scale is S=10, A+=9, A=8, B+=7, B=6.5, C+=6 and C=5. NPTEL/SWAYAM courses use separate mark ranges.
Regulations 2021 · B.E./B.Tech. Affiliated
Scope: B.E./B.Tech. cohorts governed by R2021 in affiliated non-autonomous institutions
Uses O=10, A+=9, A=8, B+=7, B=6 and C=5. Relative grading applies to relevant course cohorts; absolute mark ranges are not a universal marks-to-grade rule.
Campus and college scope
Exact SGPA and CGPA formula
GPA / CGPA = Σ(Credits × Grade Point) ÷ Σ(Credits of successfully cleared counted courses)
Multiply each included course’s credits by its grade point. Add the weighted points, add the included credits, then divide. For CGPA, use all counted courses across the semesters covered by your university record. A simple average of semester results is correct only when the counted credits match.
Included and excluded subjects

Courses with the published grade points below are included when they carry counted credits.

- B+: Good · 66–70

CGPA to percentage conversion
Percentage of Marks = CGPA × 10. Use this only for the programme and regulation covered by the source record.
Conversion rules are not interchangeable. A formula from another university, batch or unofficial website does not replace the source linked below.
Open the Anna University conversion calculatorTarget CGPA for the next semester
To plan a target, use your current CGPA, completed counted credits, target CGPA and expected next semester credits. The required next GPA is:
[Target CGPA × (completed credits + next credits) − current CGPA × completed credits] ÷ next credits
This record uses nearest rounding for the displayed target result. Keep the unrounded value while planning and exclude courses that the regulation does not count.
Open the Anna University target CGPA calculatorWorked example
Suppose three included courses carry 4, 3 and 2 credits with grade points 8, 9 and 7. The weighted points are 32, 27 and 14. Their total is 73 and the counted credits total 9, so the semester result is 73 ÷ 9 = 8.11 when displayed to two decimals.
This is an illustration, not an official Anna University transcript calculation. Replace the example values with the course credits and grade points that your regulation counts.
Common input mistakes
- Choosing a regulation because it gives a better result instead of matching your batch and programme.
- Entering marks where the calculator expects a grade point, or using the wrong university grade table.
- Including audit, pass/fail, withdrawal, exemption or non-credit entries without checking the source clause.
- Taking a simple average of semester SGPAs when the semesters have different counted credits.
- Rounding each intermediate value before the final division or conversion.
