Build a data-driven hiring forecast — know exactly how many roles you need to open per quarter and when.
Number of employees at the start of the planning year
Target number of employees at end of the year
Expected percentage of employees who will leave this year
From job opening to offer accepted
Total cost per hire (recruiting + onboarding)
Total Hires = Growth Hires + Attrition Backfills = (End − Start) + (Start × Attrition%)In plain English
Total hires = (target − start headcount) + (start × attrition rate). Quarterly pace = total / 4.
Worked Example
20 → 35, 12% attrition. Growth: 15. Attrition: 20×12% = 2.4 ≈ 3. Total: 18 hires. Quarterly: 5 hires/quarter.
The most common mistake: starting to recruit when a seat becomes empty. By then, the role is already impacting productivity. Start recruiting 6–10 weeks before you need someone to start, accounting for time-to-hire and notice period.
For a balanced pipeline: every open role needs ~5 candidates screened, 3 interviewed, 2 reaching final stage to get 1 offer accepted. If your offer acceptance rate is below 70%, add more pipeline volume.
| Role Type | Time to Hire | Pipeline Needed | Lead Time | Status |
|---|---|---|---|---|
Entry-level | 3–4 weeks | 3–5 candidates | 5 weeks | |
Mid-level | 5–7 weeks | 5–8 candidates | 8 weeks | |
Senior | 8–12 weeks | 8–12 candidates | 12 weeks | |
Executive | 12–20 weeks | 10–20 candidates | 16 weeks |

Not accounting for attrition in the hiring plan
If 12% of your team leaves annually, your "zero growth" hiring plan still requires 12% of headcount in backfill hires. These are real roles with real recruiting costs — budget for them explicitly.
Planning all hires to start in January
Spreading hires evenly across quarters is more operationally manageable than clustering. 5 new starters in one week overwhelms onboarding. Plan start dates with at least 1–2 weeks between starts for dedicated attention.
Not building in candidate drop-off rates
If you need 5 people, you need to close 5 offers, not just source 5 candidates. Account for ~20–30% offer acceptance failure, interview attrition, and sourcing conversion rates when building pipeline targets.
