How to calculate FTEs?
Full-Time Equivalents (FTEs) are calculated by estimating workload volumes and applying FTE efficiency ratios.
Formula:
- Workload Volumes × FTE Efficiency Ratios = Required FTEs
1. Workload Volumes
The total expected number of activities or outputs within a specific period.
- Example: 4 feasibility studies per year.
2. FTE Efficiency Ratios
The number of FTEs needed to complete one unit of activity.
- Example: 0.5 FTE per feasibility study.
3. Outputs
The total number of employees (FTEs) required based on the workload.
- Example: 4 studies × 0.5 FTE = 2 FTEs required per year.

Three key design principles are considered in order to develop manpower requirements:
1. Lean Organization
Manpower requirements should be optimized ensuring the building of inhouse capabilities according to company needs and management & oversight of other outsourced functions continuously or on an as-needed basis.
2. Increasing Efficiency Factor
An Efficiency Factor is adopted to account for the increasing efficiency / productivity of manpower with time for repetitive tasks, allowing the same workload to be completed by less FTEs.
3. Organization Phasing
Manpower requirements for each function depends on the organization lifecycle stage of a given company.
