Enter classes attended and held to see your attendance percentage, how many classes you can miss, or how many you must attend to reach your target.
To reach a target attendance, attend n more classes in a row, where n is the smallest whole number that makes (attended + n) divided by (held + n) at least the target. With 27 of 40 classes attended and a 75% target, n is 12: 39 of 52 is exactly 75%. If you are already at or above the target, the question flips and the page tells you how many classes you can miss. With 30 of 36 attended (83.33%) and a 75% target, you can miss 4 more, because 30 of 40 is exactly 75% and 30 of 41 is 73.17%. The page uses whole-number arithmetic on the target, so a result that lands exactly on the target counts as meeting it. It never relies on a rounded decimal that could tip a borderline case the wrong way.
A required attendance of 75% is common in colleges and universities in India, and some boards, courses and programmes use 80% or 85%, or allow a condonation of a few percentage points with a medical certificate or a fee. Schools in other countries set their own limits too, often through a state, district or school policy. This page does not know which rule applies to you. It starts at 75 because that is the most common figure, and you can type any target above 0 up to 100, with at most two decimals, such as 77.5. Check your handbook or regulations for the exact figure, how the term is counted, and whether lab sessions, tutorials and holidays count as classes held.
If you add how many classes are left this term, the page works out how many of them you must attend by the end. With 30 of 40 attended, 20 left and a 75% target, the term will have 60 classes, so you need 45 attended in total: 15 of the 20 left, and you can miss up to 5. If the target can no longer be reached, the page says so and shows the best possible final figure. With 20 of 40 attended and only 5 left, even attending all 5 gives 25 of 45, which is 55.55%. A target of 100% can only be met if you have missed nothing so far, since a missed class can never be made up. Percentages are shown cut off, not rounded, so 74.996% reads as 74.99% and is never presented as 75%. Nothing you type is stored or sent.
Divide classes attended by classes held and multiply by 100. If you attended 27 of 40 classes, that is 27 ÷ 40 × 100 = 67.5%. Count every class your institution counts as held, not just the days you checked.
Attend n classes in a row, where n is the smallest whole number with (attended + n) ÷ (held + n) ≥ 0.75. With 27 of 40 attended, n = 12, because 39 of 52 is exactly 75%. Attending 11 gives 38 of 51, which is 74.50%, still short.
The largest m with attended ÷ (held + m) ≥ 0.75. With 30 of 36 attended you can miss 4: 30 of 40 is exactly 75%. A fifth miss gives 30 of 41, which is 73.17%, below the line.
Enter the classes left. You need at least target × (held + left) attended in total, rounded up. With 30 of 40, 20 left and 75%, you need 45 of 60, so attend 15 of the 20 left. With 20 of 40 and 5 left, the best you can get is 25 of 45, which is 55.55%.
Every class held stays in the total. With 39 of 40 attended, attending the next 100 gives 139 of 140, which is 99.28%. Attendance only approaches 100% and never gets there, so the page reports the target as unreachable.
No. Percentages are cut off, not rounded up, and the check uses exact whole numbers. 74.996% shows as 74.99% and counts as below 75%. Your college may round differently, so ask your department if you are within a fraction of the line.
