Attendance Calculator
Students and teachers can find the exact attendance percentage from classes attended and total classes held, then see how many more classes to attend in a row to reach 75–90% targets — or how many can be skipped while staying above them.
Current Attendance
—
Select a target and enter attended and total classes.
How many classes you can miss will show here.
How to use
- Enter the classes attended so far and the total classes held.
- Select your target — 75%, 80%, 85% or 90%.
- You will get two clear answers with the current percentage: how many classes in a row you must attend to reach the target, and how many you can miss while staying above the target.
- The result updates live as you change the values.
Tips
- The calculator updates live, so compare targets from 75% to 90% instantly and see how the answer changes.
- The “must attend in a row” count assumes zero misses in between — one miss raises the number.
- The miss margin counts classes you can skip from today while staying above target; it is not a leave balance.
- If you are exactly at the target, treat the miss margin as zero — skipping even one class can drop you below it.
