Enter your class totals to see the result.

Attendance planning

Current attendance is attended classes divided by classes held, multiplied by 100.

10-point SGPA scale

SGPA is calculated using credit-weighted grade points. Check your university's grading rules.

Private by design

Your marks and class numbers are processed locally and are not saved.

PRACTICAL NOTES

Understand the calculation before using the result

How to approach it

Attendance is attended classes divided by classes held, multiplied by 100. The recovery figure assumes you attend every next class. SGPA is the sum of credits × grade points divided by total credits. Enter a numeric grade, including 0 for a genuine zero result.

A concrete example
With 30 attended out of 40 classes, attendance is 75%. To reach 80%, attend the next 10: 40 out of 50 is 80%. For 4 credits at grade 8 and 2 credits at grade 9, SGPA is (32 + 18) ÷ 6 = 8.33.

Before you use the result

CGPA rules differ. Enter previous semester credit totals for a weighted estimate; leaving them blank assumes equal semester credits. The calculator uses a 10-point scale and does not handle institutional exclusions or convert CGPA to percentage. Check your university’s rules.

Attendance Calculator questions

Can I calculate the classes needed for 75% attendance?

Yes. Enter classes held and classes attended, and leave the target at 75. The recovery estimate assumes you attend every next class.

Does this use KTU or VTU-specific grading rules?

No university-specific formula is implemented. The grade calculator uses the credits and numeric grade points you enter; confirm your institution’s calculation rules before relying on the result.

How is CGPA weighted across semesters?

Enter previous semester credits alongside the SGPA values for a weighted estimate. Leaving the credit totals blank assumes equal semester credits.

Does the calculator convert CGPA into percentage?

No. The percentage tab calculates marks obtained divided by maximum marks. It does not apply a university-specific CGPA conversion formula.

STUDENT CALCULATIONS

Keep attendance, grade points and marks separate

These tabs answer different questions. Attendance compares attended classes with classes held. SGPA averages course grade points using their credit weights. CGPA combines semester results under the assumptions you enter. Percentage compares marks obtained with maximum marks. A university can publish its own rules for each figure, so first identify the number you need for a form or academic decision. Do not convert one result to another just because both are displayed on a 0 to 100 or 0 to 10 scale.

Check attendance inputs against your register

Enter only classes that have actually been held and counted by your institution. If a lecture was cancelled, the denominator may not change. If a lab counts as more than one session, follow the unit used by the official attendance record. The recovery estimate assumes you attend all future counted classes until the target is reached. A change to the timetable or a missed class changes that result. For a 75 percent target, use the focused attendance page when you want worked examples and an absence-buffer explanation.

Understand credit weighting

For SGPA, each subject contributes its grade point multiplied by its credits. Divide the total of those products by the total credits. A four-credit subject therefore affects the average more than a two-credit subject with the same grade. Enter a real zero grade point as zero; leaving it blank can change what is included. Check whether your university excludes pass/fail courses, audits or repeated subjects, because this general calculator does not implement every institution's policy.

Be precise about CGPA

When you have previous semester SGPAs and credit totals, use the credit totals to create a weighted estimate. If you leave those totals blank, the tool assumes semesters have equal weight. That can be misleading when one semester carries more credits than another. Compare the result with your official transcript before putting it on a resume or application. Rounding at each semester can also produce a small difference from a university calculation based on raw course grades.

Use marks percentage for marks

Percentage here is marks obtained divided by maximum marks, multiplied by 100. It is not a CGPA-to-percentage conversion. If a form asks for a university-certified percentage equivalent, find the rule on your institution's transcript or official notice. Keep the original marks and maximum marks available so you can explain the number you entered. A calculator can prevent arithmetic mistakes, but it cannot decide which subjects or attempts your college includes.

Recheck all inputs before relying on a result: a single wrong credit, grade point or held-class count can change the answer. Use the displayed value as a planning aid and the official academic record for final reporting.

When you compare results from classmates, make sure you used the same credit scheme and attendance unit. Two correct calculations can differ because one person entered lecture sessions and another entered teaching hours. Write down the inputs with the result instead of saving only the final number. That makes it possible to explain or correct the estimate when the official record changes.
