Attendance Projection Calculator
See how future attendance or absences could change your current attendance percentage before the course ends.
Check the denominator after every planned class
Start with an example of 24 attended classes out of 30 held: the current rate is 80%. If five additional classes are all attended, the projected rate is 29 ÷ 35 × 100 = 82.86%. Missing the following two classes brings the same student to 29 ÷ 37 × 100 = 78.38%. A plan that adds five percentage points to the old rate instead of updating both counts is incorrect.
The output is only as reliable as the attendance record entered. Some schools distinguish scheduled, held, cancelled, excused or mandatory lab sessions, and those policy rules can change the denominator. Compare the projected count with the official portal before relying on a minimum-attendance threshold.

Formula
projected attendance = (attended + future attended) ÷ (classes held + future attended + future missed) × 100
Update both counts when future meetings are added
- Start with 27 meetings attended out of 30 held.
- Attending 8 of the next 10 and missing 2 produces 35 attended out of 40 total meetings: 87.5%.
What the result tells you
Attending most future meetings can still lower a current 90% attendance rate because the future rate in this example is only 80%.
Before you use the result
This is a scenario rather than a timetable lookup. Recheck remaining meeting counts when cancellations, holidays or the course schedule change.
Useful for
- Attendance planning
- Future absence scenarios
- Course participation tracking
Questions
Can I test a future absence scenario?
Yes. Enter how many future classes you expect to attend and miss; the calculator adds both to the projected class total.
Does an excused absence count?
That depends on your institution. Enter only the meetings your official attendance policy counts.
