Enter your classes attended and total classes held to get your attendance percentage right away. Set a target attendance rate (like 75%) and the calculator also tells you how many more classes you need to attend — or how many you can safely skip — to hit your goal. Also try the calculate Class Size.

Attendance percentage is calculated using the formula: (Classes Attended ÷ Total Classes Held) × 100. For example, if you attended 42 out of 56 classes, your attendance is (42 ÷ 56) × 100 = 75%. This calculator does that math for you automatically.
Most educational institutions require a minimum attendance rate — commonly 75% — to allow students to sit for exams or receive credit. Chronic absenteeism (missing 10% or more of school days) is strongly linked to lower academic achievement and higher dropout risk. Tracking your attendance helps you stay on course.
This depends on your total classes and your institution's required percentage. The calculator works out exactly how many classes you can afford to miss while still meeting your target, factoring in remaining classes left in the term. If you're already below the target, it will tell you how many consecutive classes you need to attend to recover.
If your current attendance is below the target, the calculator shows how many additional classes you need to attend — assuming you attend every remaining class — to reach the required rate. If it's mathematically impossible given the remaining classes, you'll see that reflected in the result.
Attendance rate measures the percentage of classes attended, while absence rate measures the percentage of classes missed. They are complementary: if your attendance rate is 75%, your absence rate is 25%. Both metrics are used in academic and workplace settings to monitor participation.
Chronic absenteeism is generally defined as missing 10% or more of scheduled school days or classes, regardless of whether the absences are excused or unexcused. Research shows chronically absent students are significantly more likely to struggle academically and fall behind their peers.
Yes. While the calculator is designed with students in mind, the same formula applies to employee attendance. Enter working days present and total working days scheduled, then set your organisation's required attendance or presence rate to see the results.
Most schools and colleges set 75% as the minimum acceptable attendance rate, though many institutions require 80% or higher. For employees, an attendance rate above 96% (roughly missing fewer than 8 days per year in a full-time role) is generally considered good. Higher attendance consistently correlates with better outcomes.
