About attendance calculator
Many schools and colleges need a minimum attendance, often 75 percent. The calculator shows your current percentage and how many classes you can still miss.
Formula
Attendance % = classes attended ÷ total classes × 100. If you have attended 60 of 80 classes, that is exactly 75%.
Planning ahead
- To stay at 75% you can miss at most one class out of every four.
- If you are below the requirement, work out how many consecutive classes you must attend to recover.
- Medical leave rules differ by institution.
A worked example
You have attended 51 of 70 classes, which is 72.9 percent and below a 75 percent requirement. If you attend every class from now on, you need at least 6 more to reach 75 percent, since (51 + 6) ÷ (70 + 6) = 75 percent.
How many can you miss
With 60 of 70 classes attended and 30 still to come, you need 75 of 100 in total, so you must attend at least 15 of the remaining 30 and can miss up to 15.
