How this calculation works
Attendance planning has two different limits: the total future absences compatible with an end-of-schedule target, and the consecutive classes you can miss immediately without falling below it. Enter the classes already conducted, attended and still scheduled. The calculation also shows how many consecutive attendances would recover the target and whether the remaining schedule is long enough.
Worked example
This example uses illustrative inputs. Your current result is shown above.
With 68 of 80 classes attended and 20 remaining, a 75% target permits 13 total future absences if the other 7 classes are attended: (68 + 7) ÷ 100 = 75%. Only 10 consecutive classes can be missed immediately while maintaining the target.
Assumptions and limits
- Every future class has equal weight and institutional rounding or condonation rules are excluded.
- The total absence allowance applies at the end of the entered schedule. Recalculate the consecutive allowance after attending more classes if the target must be maintained throughout.
Questions people ask
Why can total future absences be higher than the number I can miss now?
The total allowance assumes you attend every other remaining class. Those future attendances improve the ratio. Missing all permitted absences immediately can temporarily put you below the target, so use the consecutive allowance when the threshold must hold throughout.
Does the calculator know my college’s attendance requirement?
No. Enter your required target. The calculation assumes equal-weight classes and does not apply condonation, rounding concessions, medical leave or subject-specific policy.
What if the target is not reachable in the remaining classes?
The best-case result assumes attendance at every remaining class. If that still falls short, changing the order of absences cannot solve it under the entered schedule; verify the schedule and consult the institution about its actual rules.
