Class Attendance Planner
The forward-looking version of the attendance calculator: given how many classes have been held and attended so far, and how many remain, how many of those remaining classes must you attend to finish above your target? It also shows your final percentage if you attend everything from here.
Classes to attend from here
7 classes
Attend them all and you finish at 80%.
- Attend the minimum
- 75% final
- Attend everything
- 80% final
- Remaining classes
- 10
How it works
- Enter classes attended so far and total classes held so far.
- Enter the number of classes remaining in the course.
- Set your target attendance percentage (default 75%).
- The planner returns the minimum classes to attend, your projected final percentage, and whether the target is already secured — or unreachable.
The formula
Classes needed in the remainder
needed = ceil(target ÷ 100 × (held + remaining) − attended)
Work backwards from the end-of-course target: the total attendance required, minus what you've already banked.
Worked example
Worked example
- Attended: 38 · Held: 50 · Remaining: 10 · Target: 75%
- Total at end = 60; required attendance = 0.75 × 60 = 45
- Needed = 45 − 38 = 7 of the remaining 10 classes
Attend at least 7 of the last 10 classes — and all 10 gives 80%.
Common mistakes
- Forgetting that the denominator grows as classes are held — the target is a ratio, not a fixed count.
- Planning to the exact minimum with zero buffer — one illness and you're under.
- Using the number of classes instead of the attendance the university records.
Frequently asked questions
I've already missed too many — can I still recover?
If needed > remaining classes, the planner marks the target impossible and shows the maximum percentage you can finish with. Talk to your instructor about makeup policies.
Should I aim above the minimum?
Yes — target a few points above the requirement so one unexpected absence doesn't sink you. The planner lets you test different targets.
What if attendance is counted per course or per lecture?
Enter per-course numbers as described. If some sessions are worth double (labs), count them by their attendance value.
