Frequently Asked Questions
What are education calculators?
They are free online tools that handle the everyday number work of studying: attendance percentages, marks and grades, GPA and SGPA, and statistics. Each one shows the formula and explains the result so you learn as you calculate.
How do I calculate my attendance percentage?
Divide the classes you attended by the total classes held and multiply by 100. The attendance calculator also tells you how many classes you can skip or must attend to stay above your required minimum.
How do I convert marks into a percentage?
Divide your marks obtained by the maximum marks and multiply by 100. The marks percentage calculator does this for one exam or for all subjects added together, and shows the usual division band.
What is the difference between SGPA and CGPA?
SGPA is your grade point average for a single semester, weighted by credits. CGPA is the cumulative average across all semesters. The SGPA calculator computes one semester from your subject credits and grade points.
Are these calculators free to use?
Yes. Every education calculator here is free, works in your browser, and stores nothing you enter unless you choose to save a result on your own device.
These tools are for general study help only. Grade boundaries, attendance rules and grade-point scales vary by school, board and university - always confirm against your official records and policies.
