What is an Attendance Percentage Calculator?
An Attendance Percentage Calculator is a free tool that turns your attended and total class counts into a percentage. The formula is simple: Attendance % = Attended / Total x 100. If you are below your target, it works out the smallest number of classes you must attend in a row so that (Attended + x) / (Total + x) reaches your target; if you are at or above your target, it shows how many classes you can miss and still stay at target, using floor((Attended - Target x Total) / Target).
How to Use the Attendance Percentage Calculator (Step by Step)
- Enter the number of classes you have attended so far.
- Enter the total number of classes held.
- Set your target percentage (most colleges require 75%).
- Press Calculate to see your attendance percentage and your plan.

Frequently Asked Questions (FAQs)
How is attendance percentage calculated?
Divide classes attended by total classes held and multiply by 100 - per subject and overall, if your college tracks both.
My college needs 75 percent - how many classes can I bunk?
Enter your numbers with target 75 - the calculator shows exactly how many more you can miss without dropping below it.
Does medical leave count in attendance?
Most colleges give separate condonation for approved medical leave; the percentage formula stays the same but the effective total may be adjusted by your institution.
Should I calculate per subject or overall?
Follow your college rule - many universities require the minimum in EACH subject, not just overall.
