Absence Rates Velocity Calculator Examples
Worked examples showing how absence rate velocity changes across different periods and starting rates.
These examples demonstrate how to interpret total percentage-point movement, average monthly velocity, and relative change from the starting absence rate.

How to Read Your Results
A positive monthly velocity means the ending absence rate is above the starting rate.
A negative monthly velocity means the ending absence rate is below the starting rate.
Total rate change is a percentage-point difference, while relative change is a percentage of the starting rate.
Compare velocities only when rates were produced using consistent definitions and comparable periods.
Use the result as a trend summary, not evidence that change occurred evenly each month.
Assumptions & Important Notes
- Each example uses rates calculated consistently at the start and end of the period.
- Monthly velocity is a simple average of the endpoint movement.
- Examples do not adjust for seasonal effects, workforce changes, or unusual events.

Frequently Asked Questions
How do I calculate absence rate change per month?
Subtract the starting rate from the ending rate and divide by the number of months between the two measurements.
Is -0.20 percentage points per month a good result?
It indicates that the measured absence rate decreased on average. Whether that is meaningful depends on the context and consistency of the underlying data.
Why can a small percentage-point change have a large relative change?
Relative change is calculated against the starting rate, so a small baseline can make the relative percentage appear large.
Can I use annual absence rates in this calculator?
Yes, if the two rates are comparable. Enter 12 months for a one-year interval.
