How to use it
Enter how many days you were present and how many you were absent. The calculator adds them to get the total and works out the percentage of days you attended.
Formula
Attendance % = (days present ÷ (days present + days absent)) × 100Examples
Example: 82 days present and 8 absent. Total = 90, so attendance = 82 ÷ 90 × 100 = 91.1%.
Example: 70 present and 30 absent. Attendance = 70 ÷ 100 × 100 = 70%.
