Attendance Percentage Calculator
Get attendance percentage for a student or a whole class, and see how many classes are needed to reach 75% or how many can be missed.
Calculate Attendance Percentage
Use this tool to check whether a student meets the minimum attendance requirement. Most CBSE, ICSE, and state board schools require 75% attendance as a minimum. RTE norms also use attendance data for compliance reporting.

Classes Needed for 75% (or Classes You Can Miss)
Attendance is still running? Enter classes held so far and classes attended. The calculator tells you how many classes in a row are needed to reach the target, or how many can be missed while staying above it.

How it is worked out
Classes needed = (target × held − 100 × attended) ÷ (100 − target), rounded up. Example: 60 of 100 attended, target 75%: (7500 − 6000) ÷ 25 = 60 classes in a row.
Classes you can miss = (100 × attended − target × held) ÷ target, rounded down. Example: 90 of 100 attended: (9000 − 7500) ÷ 75 = 20 classes.

How Attendance Percentage Is Calculated
The formula is straightforward:
Attendance % = (Days Present ÷ Total Working Days) × 100
For example, if a school had 220 working days and a student attended 198 days:
(198 ÷ 220) × 100 = 90%
Why Attendance Tracking Matters
Regular attendance tracking is not just a compliance requirement — it directly impacts learning outcomes. Here is why schools should monitor attendance closely:
- Board exam eligibility: CBSE and most state boards require minimum 75% attendance to appear for final exams
- RTE compliance: Schools must report attendance data to government portals including UDISE+
- Early intervention: Identifying students with falling attendance helps prevent dropouts
- Parent communication: Accurate attendance data strengthens parent-teacher interactions
- Scholarship eligibility: Many government scholarships have attendance thresholds
Minimum Attendance Requirements by Board
| Board / Authority | Minimum Required | Consequence |
|---|---|---|
| CBSE | 75% | Detained / not eligible for board exams |
| ICSE / ISC | 75% | Cannot appear for final exams |
| State Boards (most) | 75% | Varies by state |
| RTE Act (Classes 1-8) | No minimum for promotion | Attendance tracked for compliance |
| NAAC (Colleges) | 75% | Not eligible for exams |

Classes needed = (75 × classes held − 100 × classes attended) ÷ 25, rounded up. With 60 of 100 classes attended you need 60 more classes in a row. Use the "Classes Needed for 75%" calculator above for your own numbers or a different target.
Classes you can miss = (100 × classes attended − 75 × classes held) ÷ 75, rounded down. With 90 of 100 attended you can miss 20 classes and still be at 75%.
In CBSE and most state boards, students with less than 75% attendance may be detained or not allowed to appear for board exams. Schools typically issue warnings at 80% and 75% thresholds.
