Attendance Percentage Calculator

Calculate your attendance percentage from classes attended and total classes, and see how many more you need to reach a target attendance rate.

Enter the classes you've attended and the total number of classes, plus your desired attendance percentage. The calculator shows your attendance rate, the classes missed and how many more you must attend to hit your target.

Attendance
Classes missed
More classes needed for {desired_pct}%

An attendance percentage calculator turns your attended and total classes into a percentage, and works out how many more sessions you must attend to reach a target attendance rate — useful for meeting school or visa requirements.

The maths

  • Attendance % = attended ÷ total × 100
  • Missed = total − attended
  • To reach a target T%: solve (attended + x) ÷ (total + x) = T/100 for x

Examples

  • 42 of 50 classes = 84% attendance
  • 8 classes missed
  • To reach 90% from 42/50 you'd need many more perfect classes

Frequently asked questions

Why does reaching a higher target need so many classes?

Because future classes count in both the numerator and denominator, lifting a high percentage the last few points takes a lot of perfect attendance — the maths compounds against you.

What if I've already met my target?

The 'more classes needed' shows 0, meaning you're already at or above your desired attendance rate.

Just for the giggles, much love.
