Less guessing. More perspective.

One job, done carefully.

Enter the lectures held, the lectures you attended and your course’s required percentage. BunkMeter shows how many consecutive classes you can miss while meeting that target, or how many you must attend to recover.

A plan that respects the whole term.

If you know how many classes remain, add them. You will see whether recovery is possible and how many of those remaining classes you need to attend. A term-end allowance assumes you attend the other remaining classes; it is not permission to miss them all at once.

See what one class changes.

The Attendance Instrument responds to your counts and target. The future preview lets you explore attending or missing a run of classes without changing your current calculation.

The website is a quick calculator: enter the official counts for each subject separately and share a result link if you want to keep the numbers. Previous website records remain in your browser and can be exported from the calculator’s backup option. Do not clear site data before exporting them.

Understand the limits.

Whole-class decisions use exact integer arithmetic. The displayed percentage is truncated to two decimal places so rounding cannot disguise a shortage. The calculations assume each entered class has equal weight. Use separate counts for subjects with separate requirements, and use the official counts for approved absences.

BunkMeter is independent and is not affiliated with a college, university or academic regulator. Your institution decides attendance policy and exam eligibility.
