Convert contracted team hours into FTE and annual productive hours.
Calculated outcomes
- Annual Worked Hours
- 6,900
Assumptions and estimates
- FTE is a capacity ratio, not a headcount. Productive weeks exclude weeks not worked; productive percentage deducts non-delivery time within the remaining weeks.
- Method: FTE = total weekly hours ÷ full-time weekly hours. Productive annual hours multiply worked weeks and productive share.
- FTE is a capacity ratio rather than headcount. Exclude non-worked weeks once and apply non-delivery time within worked weeks separately.
