Annual leave calculations

The examples listed below explain how to calculate annual leave entitlement for:

  • Full time staff with no previous NHS service working for part of a leave year
  • Part time staff with no previous NHS service working a full leave year

Full time staff with no previous NHS service working for part of a leave year

The example calculation listed below is for a full time employee working for part of a year (1 April – 30 June).

A full time employee with no previous NHS service would be entitled to 202.50 hours for the full twelve months.

Calculation

Full time annual leave entitlement (202.50) divided by months of the year (12) multiplied by the number of months required (3).

202.50 / 12 x 3 = 51

51 hours will be the annual leave entitlement for a full time employee working for three months with no previous NHS service.

Bank holiday entitlements would be dependent on the number of bank holidays which fall within the required period. If there are two bank holidays during the period, the individual would be entitled to two bank holidays in addition to the annual leave entitlement calculated.

Part time staff with no previous NHS service working a full leave year

The example calculation listed below is for a part time employee working 16 hours per week with no previous NHS service for a full leave year of twelve months (April – March).

A standard working day will be based on 7.5 hours per day. This should be used for both annual leave and bank holiday calculations.

A full time (1.0 whole time equivalent) is 37.5 hours per week.

Step one

Firstly, you will need to work out the whole time equivalent for the employee.

Calculation

Number of working hours (16) divided by full time hours (37.5) equals the whole time equivalent (0.43).

16 / 37.5 = 0.43

0.43 is the whole time equivalent for an individual working 16 hours per week.

Step two

Now you need to multiply the whole time equivalent by the full time annual leave entitlement to get the part time leave entitlement. An individual working full time with no previous NHS service is entitled to 202.50 annual leave hours.

Calculation

Whole time equivalent (0.43) multiplied by full time annual leave entitlement (202.50) equals the part time leave entitlement (87.10).

0.43 x 202.50 = 87.10

87.10 is the number of annual leave hours an individual working 16 hours per week with no previous NHS service is entitled to.

Step three

Now you need to work out the bank holiday entitlement.

The standard number of bank holidays within one leave year is usually eight. This will need to be checked to ensure it is correct each year as Easter can sometimes fall early meaning there are less bank holidays in one leave year than another. There may also be additional bank holidays specific to that leave year.

An employee working full time 37.5 based on eight bank holidays would be entitled to a total of 60 hours bank holiday entitlement.

Calculation

Whole time equivalent (0.43) multiplied by full time bank holiday entitlement (60) equals the part time bank holiday leave entitlement (26).

0.43 x 60 = 26

26 is the number of bank holiday hours an individual working 16 hours per week will be entitled to.

Step four

The final step is to calculate the full leave entitlement for an employee.

Calculation

Add the annual leave (87.10) and bank holiday hours (26) together to get the full leave entitlement for this employee (113.10).

87.10 + 26 = 113.10

113.10 hours is the leave entitlement.
