Add each semester's GPA and counted credits.

Semesters

Use the semester GPA and counted credits from your applicable regulation. Do not take a simple average of semester GPAs unless every semester has the same counted credits.

CGPA formula

CGPA = Σ(Semester GPA × counted semester credits) ÷ Σ(counted credits). This is equivalent to computing all counted course credit points together. A simple average of semester GPAs is correct only when every semester has the same counted credits.

For R2021 affiliated B.E./B.Tech., the regulation explicitly excludes U grades and bases n on successfully cleared courses. R2025 also defines CGPA through the credit-weighted course model and computes it to two decimal places. Additional-course treatment can differ for Honours/Minor requirements, so use the credits counted by your applicable regulation.

Frequently asked questions

How does this Anna University CGPA calculator work?

It applies GPA / CGPA = Σ(Credits × Grade Point) ÷ Σ(Credits of successfully cleared counted courses) exactly as published in R2025 and R2021 affiliated B.E./B.Tech. regulations (R2025 clauses 20 to 21 and R2021 amendments on grade exclusions and conversion). Affiliated non-autonomous B.E./B.Tech. institutions under R2025 or R2021. University Departments and autonomous colleges can follow different regulations.

Will this match the CGPA on my official Anna University transcript?

It should, as long as you enter every counted course with the same credits and letter grade shown on your official grade sheet. This calculator was last checked against Academic Regulations 2025 · B.E./B.Tech. Affiliated on 2026-09-12 by GradeCalculator.in editorial team. If Anna University has since revised the regulation, the official grade sheet takes precedence.

How do I convert my Anna University CGPA to a percentage?

Anna University's published conversion is percentage = Percentage of Marks = CGPA × 10. Use the CGPA to percentage calculator to apply it automatically.

Regulation scope

For affiliated non-autonomous B.E./B.Tech. cohorts under R2025 or R2021. University Departments, autonomous colleges and other Anna University regulation families need their own academic record rules.

CGPA formula

CGPA = Σ(Semester GPA × Counted semester credits) ÷ Σ(Counted semester credits).

The same result comes from one course-level credit-weighted calculation. Keep excluded status grades and non-credit courses out of both totals.

What is counted

  • The official GPA for each semester and the credits that produced that GPA.
  • Only courses and credits that the applicable regulation allows in the cumulative result.

What is excluded

  • U, SA, WC under R2025.
  • U or RA, SA, WD or W under R2021, and any non-credit or excluded additional course shown separately on the record.

Worked example

A semester GPA of 8.20 over 20 credits contributes 164 points. A GPA of 7.60 over 24 credits contributes 182.40. CGPA = 346.40 ÷ 44 = 7.87.

Common mistakes

  • Taking a plain average of semester GPAs when the semester credits differ.
  • Adding a status grade or an excluded course to the cumulative credit total.
