What happens to my attendance rate if I miss one more class?

How we calculated this

Your attended count stays fixed, since an absence is not attended by definition, while the eligible-sessions total grows by however many additional absences you are considering. Using the example values above (18 of 20 sessions, one more absence), the rate moves from 90.00% to 85.71%.

The effect of one more absence gets smaller as your total session count grows, since the same single miss is a smaller share of a larger denominator; missing one more class out of 20 total moves your rate more than missing one more out of 60 total would.

Limitations

This does not know whether the absence you are considering would actually be excused under your school's policy; if it would be excused, it should not be added to "eligible sessions held" at all. Confirm your school's excuse policy before treating a specific absence as counted here.

Common mistakes

A common error is running this calculation for an absence that already happened, when it is really meant for weighing a decision you have not made yet ("should I skip this class"); if the absence already happened, use Current Attendance Rate with your updated totals instead.

Frequently asked

Can this rate ever go up after an absence?

No; an absence can only hold your rate the same (if you enter zero additional absences) or lower it, never raise it, since attended sessions never increase from missing class.

What if I am weighing several possible future absences at once?

Enter the total number you are considering as "additional absences"; the result shows the combined effect of all of them at once, not just one.

How does this relate to a minimum attendance floor?

Once you know your new rate, compare it against your floor directly, or use Absences Remaining to see exactly how much room you have left before hitting that floor.

Does this account for future sessions beyond the ones I am considering missing?

No; for a full-term recovery projection that accounts for future sessions you plan to attend, see Attendance Recovery instead.
