When hiring slips,
what changes?

Explore how hiring timing changes the staffing capacity available across a year—and the personnel costs that come with it.

Illustrative model. All figures are invented and do not represent NRC staffing or internal data.

Explore a hiring scenario.

Starting workforce: 90 full-time employees

10

All new hires start together.

Work begins at the start of month 7.

Assumed salary plus benefits.

The default example is shown below. Enable JavaScript to explore other scenarios.

6 months worked → 5.0 additional annual FTE from 10 hires.

Total annual average FTE95.05.0 FTE below month 1 reference
Personnel spending$14.250M$750,000 below reference
Year-end headcount100Same as month 1 reference

The decision behind the numbers.

Both scenarios finish with 100 employees. A 6-month hiring delay leaves 6 months worked per new hire. Those hires contribute 5.0 annual FTE, bringing the total to 95.0 including the 90 continuing employees. Modeled spending is $750,000 below the reference.

Lower spending alone does not establish improved efficiency. The next question is whether the available staffing can meet the workload and delivery commitments.

Model assumptions & calculations

All employees work full-time. The starting workforce remains for all 12 months. Hiring delay counts full months before the new hires start together: no delay means month 1; a 6-month delay means month 7, leaving 6 months worked. There are no departures or changes in compensation, and every month receives equal weight.

Additional annual FTE = additional hires × (12 − hiring delay in months) ÷ 12. Total annual average FTE = 90 continuing employees + additional annual FTE. FTE means full-time equivalent. This is a simplified measure of labor over the year; year-end headcount counts people at one point in time.

Personnel spending = annual average FTE × assumed annual cost per employee. The same cost applies to everyone; monthly spending is prorated. Figures shown in millions are rounded to the nearest $1,000; differences are rounded to the nearest dollar.

This independently created demonstration uses fictional figures and is not a reproduction of an NRC system.

Monthly FTE utilization

Each full-time employee contributes 1/12 of an annual FTE per month worked in this model. “To date” adds those contributions through the indicated month, using the full year as the denominator; it is not an annualized year-to-date average.

Year total: 90.00 existing + 5.00 new = 95.00 annual FTE.

Values are rounded to two decimals after calculation. Running totals use full precision.

Questions about the approach?

I built this to show how I frame workforce and budget questions. I’m happy to talk through the assumptions, or how this kind of analysis supports real planning decisions.
