How to Use Attendance Calculator
Enter the required attendance days for the course, program, workplace period, or event series. This is the number of days someone was expected to attend.
Enter the actual attended days. If make-up days are allowed, include them only if your school or organization counts them toward attendance.
Calculate to see the attendance rate and absent days. If attended days exceed required days, review the policy before interpreting the percentage, because some systems cap attendance at 100 percent.
Formula & Theory - Attendance Calculator
The Attendance Calculator uses attendance rate = attended days divided by required days, multiplied by 100. Absent days are calculated as required days minus attended days, with negative absence avoided in the displayed result.
The formula is straightforward, but policy definitions matter. Some institutions count late arrival as partial attendance, some exclude excused absences, and some count make-up sessions. For official reporting, use the same attendance definitions required by the institution.
Use Cases for Attendance Calculator
- Check school or training attendance percentage.
- Estimate whether additional absences would fall below a requirement.
- Summarize participation for a course, workshop, or recurring event.
