Quick answer

Attendance % = attended ÷ held × 100. To stay ≥75% after all remaining classes: you must attend enough that (attended + future attended) ÷ (held + remaining) ≥ 0.75. The bunk mode shows the maximum you can miss.

Offline note
After assets load, many browsers (Chrome/Edge/Firefox) can keep the calculator usable offline. Some browsers (e.g. Tor) or private modes block service workers — the calculator still runs online without uploading your inputs to our servers for processing.

Not an official grade report. Formulas follow common weighted averages. Your syllabus, board, or registrar always wins — scales and rounding differ. Numbers stay in your browser.

Frequently asked questions

How is attendance percentage calculated?

Attendance % = (classes attended ÷ classes held) × 100.

How many classes can I bunk and stay above 75%?

If you need min% of held classes: you may miss floor(held − min%×held/100) classes so far — or project forward with “classes remaining.” This tool solves both.
