About Work Hours Per Year Calculator

The commonly quoted 2,080-hour year assumes no leave at all. Deducting public holidays, annual leave and expected sickness typically removes 15 to 20 per cent, which is the figure capacity plans should use. Planning against contracted rather than available hours overstates capacity by roughly two months a year per person.
