How it works
A key person calculation asks an owner the question boards ask public companies: if one specific human disappeared tomorrow, what would it actually cost the business? The damage arrives in four waves, and the calculator prices each. First, the profit vacuum — the gross profit this person directly drives, multiplied across however many months a credible replacement search realistically takes, which for specialized roles runs twelve months or more. Second, client flight: revenue concentrated in accounts that trusted the person rather than the letterhead, times your honest estimate of what walks. Third, the hard cost of recruiting, signing and training a successor. Fourth, the financing tripwire lenders rarely advertise until it trips — business loans carrying personal guarantees or continuation clauses can accelerate when a named key contributor exits. Summing the waves yields the coverage target, rounded to the next fifty-thousand-dollar increment because that is how carriers quote. Structurally, the business owns the policy, pays the premium, and collects as beneficiary, turning an existential personnel event into a funded transition instead of a fire sale. For family firms the analysis carries extra weight: the founder is often simultaneously the largest asset and the least replaceable one, and siblings arguing through a crisis without liquidity is the failure mode nobody plans. Pricing depends on age, role and underwriting; the sizing logic is universal.Formula
coverage = profit x (disruption months / 12) + key revenue x (1 - retention %) + hire cost + callable debt
Tips
- Be brutal about the retention percentage — clients loyal to a person rarely stay loyal to a logo.
- Lengthen the disruption window for licensed or technical roles; recruiters charge for speed either way.
- Read your loan covenants tonight: continuation clauses triggered by one departure are common and silent.
- Pair key person cover with a buy-sell agreement when multiple owners exist — they solve different failures.
- Re-underwrite the policy after every major role change; coverage sized for yesterday's org chart underprotects today's.
