Absence Rates Habit Calculator Examples
Worked examples showing how missed habit sessions affect absence and completion rates across different routines.

How to Read Your Results
The absence rate is the percentage of planned sessions missed; a lower percentage means fewer scheduled sessions were missed.
The completion rate is the percentage of planned sessions finished; it is the complement of the absence rate.
Read the percentages with the number of planned sessions, especially for low-frequency habits where one session can have a large effect.
Compare like-for-like tracking periods and use the same definition of completion each time.
Treat the result as a record of consistency, not a measure of the value or quality of the habit.
Assumptions & Important Notes
- Every planned session is given equal weight.
- The weekly session target is the same throughout each example period.
- Missed sessions refer only to scheduled sessions that were not completed.
- No separate category is used for partial, postponed, or extra sessions.

Frequently Asked Questions
Can I use these examples for a habit that is not daily?
Yes. Change the planned sessions per week to match the frequency of your habit.
Why does one missed session matter more for a weekly habit?
A weekly habit has fewer planned sessions, so each missed session is a larger share of the total.
Can I compare a four-week result with an eight-week result?
You can compare the percentages, but longer periods usually provide a broader view of consistency.
What if I did extra sessions that were not planned?
These examples do not include extra sessions. The rates measure completion against the original planned schedule.
Is a 100% completion rate required for a useful habit routine?
Not necessarily. The calculator reports the recorded result; what is realistic depends on the habit, schedule, and tracking goal.
