How to use this calculator

Use this calculator to find an attendance percentage from days attended and total school or class days. Enter the number of days present and the total number of days counted.

Example

If a student attended 45 days out of 50 total class days, the calculator shows 90% attendance. This can help students, parents, and teachers understand attendance progress quickly.

Common mistakes to avoid

• Do not enter absent days as attended days.
• Make sure the total days number includes the full period you want to measure.
• Check whether excused absences count differently in your school.

Attendance rules can vary by school or district. This calculator gives a simple percentage, but official attendance decisions should follow the school’s policy.
