What this tool helps you find

Enter the classes attended and classes held so far, then set your target percentage. The estimate assumes each future class is either attended or missed once.

Formula

Attendance % = classes attended ÷ total classes × 100.

Worked example

75 attended out of 100 classes is 75% attendance.

Common mistake

Use classes held so far as the denominator, not the number of classes you plan to have by the end of term. School rules can round percentages differently.

When to use it

Check current attendance or plan how many upcoming classes are needed to reach a required threshold.

Questions and answers

How many classes to reach my target?

This assumes you attend every upcoming class and finds the smallest number that reaches your target.
