Key Person Insurance Coverage Calculator

What This Calculator Does and Why It Matters

Key person insurance — sometimes called key man insurance — is a life or disability policy a business takes out on an employee whose loss would cause serious financial harm. This free calculator helps business owners estimate the right coverage amount based on the key person’s revenue contribution, salary, replacement costs, and the business’s outstanding debt.

Without this coverage, losing a critical team member to death or disability can cripple a company’s cash flow, disrupt client relationships, and even trigger loan defaults. This tool gives you a starting number so you can have a more informed conversation with your insurance advisor.

The Formula Explained

There is no single universal formula for key person insurance — but three main methods are widely used by financial advisors and underwriters. This calculator supports all three so you can compare them against your specific situation.

Breaking Down the Formula

The Revenue Multiplier method calculates: (Annual Revenue × Years to Replace) + Recruiting Costs + Outstanding Debt. The Salary Multiplier method uses: (Annual Salary × 5) + Recruiting Costs + Debt. The Combined method takes the higher of the two revenue or salary components and adds both recruiting costs, debt, and the key person’s share of the total business valuation. Most advisors recommend the Combined approach for businesses where the key person drives both revenue and owns equity.

Example Calculation with Real Numbers

A business attributes $500,000 in annual revenue to their lead salesperson, who earns $120,000 per year. It would take two years to replace them, and recruiting is expected to cost $30,000. The company has $200,000 in loans and values the business at $2,000,000 with the key person holding 30 percent of that value, or $600,000. Using the Combined method: the revenue component is $1,000,000, salary component is $600,000. The higher value ($1,000,000) plus $30,000 recruiting, $200,000 debt, and $600,000 equity share gives a recommended coverage of $1,830,000.

When Would You Use This

Key person insurance is most often purchased when applying for a business loan, during partnership agreements, at the start of a new venture, or when a company’s revenue is heavily dependent on one or two individuals. Lenders frequently require it as a condition of financing.

Real Life Use Cases

Small law firms, medical practices, technology startups, and family-owned businesses are among the most common buyers of key person insurance. The policy protects the business entity, not the individual, and the benefit is paid directly to the company tax-free in most cases.

Specific Example Scenario

A software startup has a CTO who built the entire product and manages all engineering relationships. If that person suddenly left, the company could not continue development or maintain client contracts without a major disruption lasting at least 18 months. The business calculates its key person coverage need and buys a $1.5M term life policy on the CTO. This ensures the company can survive the transition and cover recruiting and rebuild costs. You can pair this planning with the Small Business Valuation Multiplier Calculator to confirm the business value inputs used in the formula.

Tips for Getting Accurate Results

Be Honest About Revenue Attribution

It is easy to overestimate how much revenue a single person generates. Try to separate team contribution from individual contribution carefully. If the key person left tomorrow, what percentage of current clients would actually leave with them? That is the number to base your revenue figure on.

Include Soft Costs of Replacement

Recruiting costs are only part of the picture. Factor in the productivity loss during the transition, training time for a new hire, potential client churn during the gap, and any temporary contract workers you might need. These soft costs often exceed the direct recruiting expense.

Revisit Coverage Annually

Business value and key person contribution change over time. Review your coverage needs every year, especially after revenue growth, new contracts, or additional debt.

Frequently Asked Questions

What is key person insurance?

Key person insurance is a life or disability insurance policy that a business takes out on a critical employee or owner. The business pays the premiums and receives the death or disability benefit if the key person is lost, helping cover financial losses during the transition period.

Who qualifies as a key person?

A key person is anyone whose loss would cause significant financial harm to the business. This typically includes founders, top salespeople, lead engineers, chief medical officers, or anyone whose skills, relationships, or knowledge are essential to revenue generation or daily operations.

Is the key person insurance payout taxable?

In most cases, key person life insurance death benefits paid to the business are income-tax-free under IRC Section 101. However, there are conditions and exceptions. Always confirm the tax treatment of your specific policy with a qualified tax advisor or CPA.

How much does key person insurance cost?

Premiums depend on the coverage amount, the key person’s age, health status, and the type of policy. A healthy 40-year-old might pay $1,000 to $2,500 annually for a $1 million 10-year term policy, but rates vary widely by carrier and underwriting result.

Can the key person be an owner or partner?

Yes. Owners and partners are often the first people businesses insure. In fact, key person coverage is frequently required by lenders and investors when a majority owner is the primary driver of company value. Partnership buy-sell agreements often include key person provisions.

What is the difference between key person insurance and a buy-sell agreement?

Key person insurance protects the business from the financial impact of losing a critical employee. A buy-sell agreement is a legal arrangement that uses life insurance proceeds to fund the purchase of a departing partner’s ownership share. They serve different purposes and are often used together.

How long should the key person policy term be?

Most businesses choose a term that matches either the time it would take to fully replace the key person or the length of a business loan that requires the coverage. Terms of five, ten, or twenty years are common. Permanent policies are less common but may make sense for long-term business protection needs.

Does the key person need to consent to the policy?

Yes. Federal law requires that employees give written consent before a business can take out a life insurance policy on them. This rule applies to all employer-owned life insurance policies under IRS Notice 2009-48 and related regulations.
