Attendance Shortage
6.43 pts
Equivalent to about 9 classes short of the requirement.
If your attendance has dropped below the required threshold, the natural next question isn't just "am I below?" but "by how much, exactly?" This calculator gives you two numbers: how many percentage points you are short, and — more usefully — how many classes' worth of attendance that shortage represents.
Knowing the shortage in actual classes (not just percentage points) makes it much easier to plan a realistic recovery, since it tells you concretely what you're working against.
Formula
Shortage (percentage points) = Required % − Current %; Shortage (in classes) = ⌈(Required% ÷ 100) × Total⌉ − Attended
If the result is zero or negative, you already meet the requirement — there is no shortage.
Worked Example
Worked example
This is a snapshot, not a recovery plan
This shortage is calculated against classes held so far — it doesn't account for classes still to come this term, which is why the number can look larger than expected. To see exactly how many upcoming classes you need to attend in a row to close the gap, use the Classes Needed Calculator next.
A shortage in classes ≠ a shortage in percentage points
A shortage of "9 classes" does not simply mean attending 9 more classes brings you to exactly 75% — because attending more classes also increases the total, which changes the ratio again. The Classes Needed Calculator handles this correctly by solving for the right number directly.
Frequently Asked Questions
How do I know how far below the required attendance I am?
Enter your attended and total classes plus the required percentage — the calculator shows your shortage both as percentage points and as an equivalent number of classes.
Does closing the "class shortage" number bring me exactly to the requirement?
Not by itself — because adding more attended classes also changes your total. Use the Classes Needed Calculator to get the exact number of future classes required to reach your target.
What if the result shows no shortage?
That means you already meet or exceed the required attendance percentage — there is nothing to recover.
