Calculate annual working hours from a weekly pattern, leave and holidays.
Contracted hours overstate available capacity because leave and holidays remove roughly six weeks of the year. The net figure is what should feed resource planning and hourly rate calculations. Dividing salary by contracted hours rather than actual working hours understates the true hourly cost by about 12 per cent.
