Guide written .
Open the FTE and productive workforce capacity calculatorWhat to prepare
- Use the contract, pay records, service dates and applicable working pattern.
- Identify the relevant jurisdiction, rule date and employee category.
- Separate contractual arrangements from statutory minima and employer-cost estimates.
Understand the inputs
The calculation method
FTE = total weekly hours ÷ full-time weekly hours. Productive annual hours multiply worked weeks and productive share.
Worked example
Illustrative inputs and their result.
Example inputs
- Total team weekly hours
- 150
- Full-time weekly hours
- 37.5
- Weeks worked annually
- 46
- Productive share within worked weeks (%)
- 80
Calculated example result
- Full Time Equivalents
- 4
- Annual Productive Hours
- 5,520
- Productive Fte Equivalent
- 3.2
How to interpret the result
A payroll or employment estimate does not determine a legal entitlement by itself. Contract terms, eligibility, service history and specific statutory exceptions can matter.
Compare the same role and working pattern when changing a pay or staffing assumption. Confirm statutory questions with the cited guidance or a qualified adviser.
Common mistakes to avoid
- Do not mix weekly, monthly and annual pay without converting consistently.
- Check whether service dates and working days are included as the method requires.
- Do not assume all employees share the same eligibility or contribution treatment.
Assumptions and sources
FTE is a capacity ratio rather than headcount. Exclude non-worked weeks once and apply non-delivery time within worked weeks separately.
