WhenMathRequired Team Capacity Calculator
Enter the total hours required, one person's weekly hours, and how many weeks are available. The result is a full-time-equivalent (FTE) ratio, a planning figure, not a hiring or staffing determination.
Worked example
80 required hours at 40 hours per person per week, over 1 available week, comes to exactly 2 FTE, two people working full weekly hours for that single week. Stretch the same 80 hours across 2 available weeks instead, and the requirement drops to exactly 1 FTE, since the identical total work is now spread over twice the time, halving how much capacity is needed at once.
Common mistakes
- Treating a fractional FTE, like 2.3, as a literal person count for a single week. A fractional result usually means the work fits real people unevenly across the available weeks.
- Assuming this accounts for part-time schedules or individual availability. It is a single ratio of three plain numbers, nothing more granular than that.
Limitations
This is a ratio of three numbers supplied directly. It does not know about individual availability, skill mix, part-time schedules, or whether the underlying work is actually divisible across multiple people.
Frequently asked questions
- Is this legal or HR advice?
- No, it is a planning ratio only, and it does not determine hiring, overtime, or employment status of any kind.
- What does a fractional FTE result like 2.3 actually mean?
- It usually means the required hours fit real people unevenly across the available weeks, not that a fraction of a person is needed. It is a planning signal to round or redistribute, not a literal headcount.
