How attendance percentage works
Attendance percentage measures how often you were present compared with every session that counted toward the total. Schools, employers, and training programs use it to track reliability and eligibility for exams, certifications, or continued enrollment.
Formula: Attendance % = (Days or sessions present ÷ Total scheduled days or sessions) × 100. Only include sessions in the denominator that your policy counts—some institutions exclude approved leave or holidays; this calculator uses the raw ratio you enter.
Tip: Confirm whether excused absences reduce the numerator, the denominator, or neither before you compare your result to a syllabus minimum (often 75–90%).
Typical attendance thresholds
Policies vary, but many schools treat roughly 95%+ as excellent, 90–94% as acceptable, and below 90% as at-risk for credit loss or exam restrictions. Workplace attendance targets often sit between 95% and 98% depending on shift coverage rules.
