What attrition will cost you post close.

If headhunters are sharks, an acquisition announcement is blood in the water.

Most deals lose 30 to 60 percent of acquired employees in Year 1. The cost shows up as recruiting fees, ramp time, lost institutional knowledge, broken customer relationships. Two minutes to see what waiting costs.

01 / Your Deal

Who's coming over?

Enter the headcount you're acquiring. We'll start with typical proportions for Tier 1 and Tier 2, and calculate Tier 3 automatically.

How this works: Enter your total headcount and Tier 3 calculates automatically (total minus Tier 1 minus Tier 2). The Tier 1 and Tier 2 fields are pre-filled at typical proportions but you can adjust either one if your deal differs.
Total acquired headcount Full-time employees at the target company
Tier 1: Executives and VPs Typical ~5 percent of workforce. Adjust if your deal differs.
Tier 2: Managers and Senior Professionals Typical ~25 percent of workforce. Adjust if your deal differs.
Tier 3: Operational and Frontline Calculated automatically (total minus Tier 1 minus Tier 2). Typical ~70 percent.

Defaults reflect BLS occupational median wages and published compensation benchmarks. Values are total cash compensation (base plus bonus), excluding equity.

Tier 1 cash comp: Executives and VPs Default $350K. Typical band: $300K to $400K.
Tier 2 cash comp: Managers and Senior Professionals Default $100K. Typical band: $70K to $120K.
Tier 3 cash comp: Operational and Frontline Default $40K. Typical band: $30K to $50K.

As soon as the deal is announced, your acquired employees are updating their LinkedIn profiles and answering recruiting calls, wondering whether their role survives, whether their boss and colleagues stay, and whether anybody on the acquiring team will understand what they do. Having a plan can save you millions.

Attrition baselines from MIT Sloan (Ng & Stuart, 7,134 acquisitions), EY post-merger integration data, and PwC's 2023 M&A Integration Survey. Replacement-cost multipliers from the Saratoga Institute (Fitz-enz), Appelbaum & Milkman, and the Center for American Progress meta-analysis (Boushey & Glynn). Compensation defaults from BLS occupational median wages and Gallagher CFO benchmarks.
