Linchpin Cost Calculator

Estimate what it costs to keep a linchpin in place, and what it costs when they leave and pull teammates with them, using your own salary, ramp-up, and turnover assumptions.

Compensation
Start from the article's worked example, its low end, or a departure that pulls nobody else with it.
$139,850
Annual base pay. Default is the BLS mean annual wage for software and web developers, programmers, and testers, May 2025.
1.43x
Total compensation divided by wages. 1.43 is the author's calculation from the BLS private industry average for June 2026 ($46.89 total / $32.82 wages), not a software-specific BLS figure.
30%
Extra pay above peers from retention bonuses, counteroffers, and off-cycle raises. 30% is an assumption; use your own.
Departure
6 months
Months before the linchpin's replacement is fully productive. An assumption.
2 people
Research on turnover contagion shows quitting spreads through coworkers. Two is an assumption.
3 months
Months before each teammate's replacement is fully productive.
$32,000
Recruiting ($10,000), coaching ($12,000), and first-year upskilling ($10,000), from The Five-Year Fix.
100%
100% counts every ramp-up month at full cost (the high end). 80% is closer to the ratio The Five-Year Fix used.
Rotation
3 months
An internal seat rotation with a planned handover. It skips recruiting, but the successor still ramps up.

Why I Built This: The Price of a Linchpin

Most teams that look stable on an org chart rest on one or two people who understand the critical systems. Leaders pay extra to keep those people in place, and when one of them leaves, the budget usually covers one open seat. In Leadership: The Stability Trap I worked through what that dependency really costs. This calculator lets you run the same math with your own numbers.

Practical Benchmarks & Assumptions

  1. Base salary: The default is the BLS mean annual wage for software and web developers, programmers, and testers: $139,850 in May 2025.
  2. Fully loaded multiplier (my calculation): 1.43 converts wages to total compensation. It comes from the BLS private industry average for June 2026, where total compensation was $46.89 per hour worked and wages were $32.82 ($46.89 / $32.82 = 1.4287). It is not a software-specific figure. The loaded cost is rounded to the nearest $100, so the defaults give $200,000.
  3. Retention premium (assumption): 30% above peers from retention bonuses, counteroffers, and off-cycle raises.
  4. Replacement costs: Recruiting (up to $10,000), coaching ($12,000 for three senior coaches), and first-year upskilling ($10,000 for senior roles) come from The Five-Year Fix. Ramp-up months are assumptions: 6 for the linchpin, 3 for each teammate.
  5. Teammates who follow (assumption): Research on turnover contagion found that coworkers' job embeddedness and job search behaviors help explain why people quit. The default of two follow-on departures is my assumption.
  6. Planned rotation (estimate): An internal move with a 90-day handover skips recruiting, but the successor still ramps up. This comparison is an estimate, not a figure from the article.

These are direct costs only. Delayed projects, missed deadlines, and knowledge that never comes back are not included, so the real number is higher.
