Compare a Cornerstone fractional engagement against a full-time VP or COO hire — including recruiter fees, benefits load, bonus, equity, and the cost of a bad hire.

Full-time hire assumptions

Base salary ($)

Typical Appalachian VP / COO range: $250K – $400K

Target bonus (% of base)

Common range: 20–40% of base

Equity / LTI ($/yr)

Annualized value of equity grant or long-term incentive

Benefits load (% of cash comp)

Health, dental, 401k match, payroll tax — typically 25–32%

Recruiter fee (% of base)

Retained search for executive roles: 25–33%

Bad-hire probability (%)

Industry research puts exec bad-hire risk at 25–40%

Cornerstone engagement

Monthly engagement fee ($)

Fractional COO retainers typically run $20K – $40K / month

Engagement length (months)

Most engagements run 3 – 12 months

The math is one input. The fit is the bigger question.

A fractional engagement is the right answer when the operational need is real but the headcount math doesn't work. A 30-minute call helps figure out which side of that line your situation sits on. No pitch.

Methodology & assumptions

Inputs reflect typical Appalachian VP / COO compensation ranges. Default assumptions:

Base salary defaults reflect Appalachian Basin VP / COO comp surveys (Hays, Robert Half, BlueSteps)
Benefits load (28%) reflects median for E&P operators including health, retirement match, and payroll tax
Recruiter fee (28%) reflects standard retained-search pricing for executive roles
Bad-hire probability (30%) reflects published executive search research (LeadershipIQ, SHRM, HBR)
Bad-hire cost is calculated as 1.0× base + recruiter fee paid + 6 months of severance (typical executive package)

Risk-adjusted full-time cost = base + bonus + equity + benefits + recruiter + (bad-hire probability × bad-hire cost). Cornerstone cost is the simple sum of monthly fee × engagement length, with no embedded risk loading because the engagement can be terminated without severance, recruiting cost, or equity dilution.

This calculator is illustrative. Actual fit depends on the specific operational need, decision authority required, and time horizon — all worth a conversation.
