Annualised Hours

Annualised Hours: Everything is calculated on a yearly basis

Annualised hours are important because when you are doing any staffing calculation you need everything to be in the same units over the same time scales. We use hours because everything can be broken down into hours, e.g. length of a shift, workload, holiday etc. We use a time scale of a year because holidays are based around a year and it covers seasonal variations.

Annualised hours is simply how many contracted hours a person will work in a year. Most contracts will state the contracted hours per week. Then you use the company definition of a year to calculate the annualised hours.

There are three possible options:

  • A year is 52 weeks
  • A year is 52 weeks and 1/7 of a week (52 2/7 weeks each leap year)
  • A year is 52 weeks if 31st December falls on a Saturday or Sunday or 52 1/5 weeks if 31st December falls Monday to Friday. (If a leap year then a year is 52 2/5 weeks if 30th December falls on Monday to Thursday)

 

Once you have calculated your staffs’ annul hours then you can calculate other useful things such as:

  • The number of staff required to do the workload,
  • How much overtime have they worked,
  • If they owe any hours,
  • Annual sickness rate.

 

This blog is an excerpt from the only shift pattern text book: How to Manage your Shift Pattern. If you are running a shift pattern this book is an invaluable guide. It covers calculating how many staff you need, the most common shift patterns, how to deal with holidays and absences, fatigue in shift work, terms and conditions for shift workers.
