- Sizing a recruitment plan and the resources behind it.
- Comparing hiring volume across scenarios or time periods.

How it works
The formula is:
Total hires = (Target − Current, if positive) + (Current × Attrition % ÷ 100)
Growth hires close the gap from current to target headcount; replacement hires cover the people you expect to lose to attrition during the period. The total is the real recruiting workload.
Worked example: Going from 120 to 150 with 10% expected attrition: growth = 150 − 120 = 30; replacements = 120 × 0.10 = 12; total hires needed = 42.
How to read the result
The headline figure is almost always higher than the visible growth, because attrition keeps removing people while you hire. Planning only for the growth gap is the classic way to fall short by year-end.
If the target is below current headcount, the growth component is zero but you may still hire to replace some attrition, depending on how far you want to let numbers fall. Treat replacement as an estimate driven by your attrition assumption.
Common mistakes
- Planning only for net growth and ignoring replacement of leavers.
- Using an attrition rate that does not match the period length.
- Forgetting that hires also take time to fill, so volume and timing both matter.
- Treating the attrition estimate as a certainty.
