What is Attendance Percentage?
The Attendance Percentage calculation tells you your attendance percentage from a few simple inputs. The figure you are solving for here is the attendance percentage, expressed in percent.
The Attendance Percentage formula
The core formula is:
Attendance percentage = Classes attended ÷ Total classes held × 100Here is what each input means:
- Classes attended — a number. Example: 68.
- Total classes held — a number. Example: 80.
How to calculate it step by step
- Write down the classes attended (for example, 68).
- Write down the total classes held (for example, 80).
- Apply the formula above to get your attendance percentage.
- Double-check the result with the Attendance Percentage Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Classes attended | 68 |
| Total classes held | 80 |
| Attendance percentage | 85.00% |
| Classes you can still skip (75% rule) | 10 |
With classes attended of 68 and total classes held of 80, the attendance percentage works out to 85.00%.
Example 2
With classes attended of 140 and total classes held of 80, the attendance percentage works out to 175.00%.
| Result | Value |
|---|---|
| Attendance percentage | 175.00% |
| Classes you can still skip (75% rule) | 106 |
Example 3
With classes attended of 34 and total classes held of 80, the attendance percentage works out to 42.50%.
| Result | Value |
|---|---|
| Attendance percentage | 42.50% |
| Classes you can still skip (75% rule) | -35 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
