About this tool

Enter the classes you attended, the total classes held so far and the minimum attendance your school or university requires. The tool shows your percentage and, if you are above the line, how many more classes you can skip, or, if you are below it, how many classes in a row you must attend to reach the minimum.

Why attendance matters

Many institutions bar students from exams below 75 or 80 percent attendance. Knowing the exact number of classes you can still miss helps you plan leave and illness.

How the numbers are found

The percentage is attended divided by total. To reach the minimum r you need x more classes where (attended + x) divided by (total + x) is at least r.

Tip

Check whether medical leave or approved absence is counted separately in your institution's rules.

Tips for best results

Check every box before you rely on a result, because one wrong digit changes the whole answer. Use the exact figures from your payslip, bill, certificate or contract, and keep a note of the date you calculated. Rates, thresholds and rules change from time to time, so for tax, fees and legal matters treat the output as an estimate and confirm with the official source named on this page. You can run as many scenarios as you like; nothing is saved or sent, and refreshing the page clears the boxes.
