About This Calculator
Attendance percentage is attended classes divided by classes held. The projection assumes each future class counts equally and that the target applies to the resulting total.
Formula & Notes
Attendance % = classes attended ÷ classes held × 100. To reach target after future attendance x: (attended + x) ÷ (held + x) ≥ target.
