Some businesses have a person the whole operation leans on: a founder, a top salesperson, the engineer who built the product. Key person insurance is a policy the company takes out on that individual, so a sudden loss does not take the business down with them.
The business buys a life insurance policy, and sometimes a disability policy, on the key individual. The company pays the premiums, owns the policy, and is the beneficiary. If the insured person dies, the payout goes to the business to cover the disruption: lost revenue, the cost of finding and training a replacement, and reassurance to lenders and partners that the company can weather the loss.
Premiums are set the way any life insurance is: by the insured person's age and health, the type of policy, and the amount of coverage. A term life policy on a healthy 40-year-old is relatively inexpensive for a sizable benefit, while permanent coverage or an older or higher-risk individual costs more. Because the variables are personal, the only real way to price it is to get quotes for your specific key person.
There is no single formula. Businesses often size the policy to the cost of replacing the person and the revenue at risk while they do, sometimes expressed as a multiple of the key person's salary or their estimated contribution to profit. The goal is enough to keep the business stable through the transition, not to overinsure.
Two points trip up small businesses. The premiums for key person insurance are generally not tax deductible, because the business is the beneficiary. In exchange, the death benefit is generally received income-tax-free, with some exceptions tied to notice and consent rules the IRS requires for employer-owned life insurance. Confirm the specifics with a tax professional before you rely on that treatment.
For a business that genuinely depends on one or two people, key person coverage is inexpensive insurance against an outsized risk. For a company where responsibilities are spread out, it may be unnecessary. The honest test is simple: if losing this person would threaten the business, the policy earns its premium. See how people-risk fits the bigger cost picture in the true cost of hiring beyond salary.
For a business with more than one owner, key person coverage often works alongside a buy-sell agreement. The idea: if an owner dies, life insurance funds the purchase of their share from their estate, so the surviving owners keep control and the family gets fair value in cash. It is a common, practical use of business life insurance, and worth discussing with an attorney and an agent together.
It is priced like any life insurance, by the insured person's age and health, the policy type, and the coverage amount. Term coverage on a healthy younger person is relatively inexpensive for a large benefit; permanent coverage or an older insured costs more. Quotes are the only way to know.
It pays the business if a key individual dies, and sometimes if they become disabled. The payout covers lost revenue, the cost of finding and training a replacement, and stability for lenders and partners during the transition. The company owns the policy and is the beneficiary.
Generally no, because the business is the beneficiary. In return, the death benefit is usually received income-tax-free, subject to IRS notice and consent rules for employer-owned life insurance. Confirm the details with a tax professional.
There is no fixed formula. Companies often size it to the cost of replacing the person and the revenue at risk during the transition, sometimes as a multiple of salary or estimated profit contribution. Enough to stay stable through the loss is the goal.
