Key person coverage calculation methods compared?

Written by Hannah McCullough Insurance Researcher & Writer

Key person coverage calculation methods compared start with one question: what would your business lose if a key person died or became disabled long term? The answer drives the coverage amount. There is no single required formula, so businesses use a few common approaches.

What is key person coverage?

Key person coverage is business-owned life insurance that protects against financial loss when a key person dies or becomes disabled long term. The business owns the policy, pays the premiums, and is the beneficiary, not the insured individual. This structure is described in the Idaho Business Portal glossary.

Some of this insurance protects against the loss of key executives, which is called key-person insurance. The employer is the beneficiary of these policies, as noted in GAO testimony.

Why compare calculation methods?

Different methods produce different coverage amounts. The right method depends on what the business wants to protect: lost revenue, replacement costs, or ownership transition. Comparing methods helps a business avoid being underinsured or overinsured.

Key person coverage can support business continuity during an ownership transition caused by the death or incapacity of an owner or key employee, according to the New York State Department of Financial Services.

Common calculation methods

Here are the methods businesses commonly use to size key person coverage.

Human life value method

This method estimates the financial contribution the key person would have made to the business over time. It considers revenue the person generates, profit margin, and expected years of service. The result is a coverage amount tied to lost future value.

For example, a sales director who brings in $500,000 of annual revenue at a 20 percent profit margin contributes about $100,000 of profit each year. If the business expects that person to work another ten years, the human life value method points toward coverage near $1 million. This is an illustration, not a rule, and the actual number depends on the business’s own figures.

Multiple of salary method

This method applies a fixed multiple, such as 5 or 10 times the key person’s salary. It is simple and easy to explain. The tradeoff is that it may not reflect the person’s true financial impact on the business.

For a key employee earning $120,000, a 5 times multiple suggests $600,000 of coverage, while a 10 times multiple suggests $1.2 million. The multiple is a starting point, not a precise measure of the loss the business would face.

Cost of replacement method

This method calculates what it would cost to recruit, hire, and train a replacement, plus any temporary disruption. It focuses on operational continuity rather than lost revenue. It works well when the key person’s main value is their role, not their revenue.

Replacement costs can include a recruiter fee, a higher starting salary, training time, and lost productivity while the new person learns the job. Adding those items gives a coverage amount tied to the practical cost of keeping the business running.

Buy-sell funding method

Key person insurance may also be used as part of a buy-sell agreement when a business has multiple owners, per the Idaho Business Portal. In this case, the coverage amount is tied to the value of the ownership interest being transferred.

When you compare key person vs buy sell coverage, the key difference is the goal. Key person coverage protects the business from financial loss. Buy-sell coverage funds the transfer of an owner’s interest. Both can use life insurance, but they answer different questions.

How to choose a method

Start with the loss you want to cover. If the key person drives revenue, use the human life value method. If you need a simple estimate, use a multiple of salary. If the concern is replacing the person, use the cost of replacement method. If you have multiple owners, consider buy-sell funding.

Banks or government loan programs may require key person insurance in some circumstances, according to the New York State Department of Financial Services. If a lender requires it, the coverage amount may need to meet the lender’s terms.

What to prepare before you get an estimate

Before you talk to a licensed life insurance agent, gather a few facts. You will want the key person’s role and compensation, the business’s annual revenue, and the profit the person helps generate. You may also need the ownership structure if a buy-sell agreement is involved.

Having these numbers ready makes the estimate conversation faster and more useful. The agent can then apply the method that fits your situation and show what coverage might cost.

Next step: get a coverage estimate

Once you have a method in mind, a licensed life insurance agent can help you turn that number into a policy. You will typically provide the key person’s role, compensation, and the business’s revenue. An estimate can show what coverage might cost before you commit.
