The mathematical formula is:

( [Number of missed hours] divided by [Maximum possible work hours] ) multiplied by 100

For example if your employee could work a maximum of 40 hours per week, and they missed 3 hours of work, then the sum would be:

(3 ÷ 40) x 100 = 7.5%

In this example the answer would be a lost time rate of 7.5%.

How does lost time rate compare to the Bradford Factor method?

The Bradford Factor is a calculation that is used to measure employee absence. It takes into account the number of times an employee has been absent, as well as the length of their absences, while the lost time rate only looks at the total number of hours missed.

The Bradford Factor can be more useful for businesses who want to get a more detailed picture of employee absences, while the lost time rate is more useful for calculating the financial impact of absences.

Both the Bradford Factor and lost time rate are important tools for businesses to have in their arsenal, and can be used together to get a complete picture of employee absences.
