Quick answer: A key person discount is a reduction in a business’s value that reflects its dependence on one individual — an owner, founder, or rainmaker — whose departure, death, or disability would impair the company’s earnings. The IRS framework for valuing closely held businesses, Revenue Ruling 59-60, expressly recognizes this risk. There is no standard percentage. The most defensible approach measures the actual financial impact by comparing the company’s expected cash flows with and without the key person, rather than applying an arbitrary discount, and the size of any adjustment depends on how replaceable the person is and whether safeguards — a trained successor, key person insurance, and a non-compete agreement — are in place.
Many small and mid-sized companies are, in economic reality, one person. The founder holds the client relationships, the technical expertise, the lender contacts, and the reputation that drives revenue. When that business is valued — for an estate, a divorce, a buyout, or a dispute — the analyst must determine how much of its value would survive the loss of that individual. The answer is captured in the key person discount.
What a key person discount is
A key person discount adjusts a company’s value downward to reflect company-specific risk arising from over-dependence on a single individual. It is not an arbitrary penalty; it is a recognition that a buyer would pay less for a business whose earnings could collapse if one person left.
This concept is grounded in the foundational IRS valuation authority. Revenue Ruling 59-60, the 1959 framework that courts and appraisers still use to value closely held stock, recognizes that the loss of the manager of a so-called “one-man” business may have “a depressing effect upon the value of the stock,” particularly where the company lacks trained personnel capable of succeeding to management. In other words, the IRS itself instructs analysts to consider key person risk.
When a key person discount applies
A credentialed valuation analyst evaluates key person risk in several settings:
- Estate and gift tax valuation — the classic Revenue Ruling 59-60 context, where a closely held business is valued after the founder’s death or when shares are gifted.
- Shareholder and partner disputes, where one owner’s centrality to the business is contested. See partnership buyouts and disputes.
- Divorce, where the marital business must be valued and the owner-spouse’s personal involvement is central (discussed below).
- Buy-sell agreements, where the value triggered by a death or departure should account for the very risk the agreement addresses. See business valuations for buy-sell agreements.
- Economic damages, where the loss of a key person is itself the harm being measured.
How a key person discount is quantified
There are three recognized methods, and they are not equally persuasive:
- Cash-flow adjustment (the most defensible). The analyst models the company’s expected cash flows with the key person and without the key person, then weights the difference by the probability that the person departs, dies, or becomes disabled during the period. Because the result is tied to specific revenue losses and added costs — recruiting a replacement, lost clients, transition disruption — it is far easier to support than a bare percentage. This is the preferred approach in contested matters.
- Company-specific risk premium. The analyst builds the key person risk into the discount or capitalization rate as an incremental specific-company risk premium, which is then applied to the company’s expected earnings. A higher rate produces a lower value, capturing the elevated risk.
- Entity-level percentage discount. The analyst applies a percentage directly to a preliminary conclusion of value. As an illustration of the mechanics only, a preliminary value of $1,000,000 with a supportable 20% key person discount would yield $800,000. This method is the least persuasive unless the percentage is itself supported by analysis — an unsupported number invites challenge.
Across all three, the governing principle is the same: courts and the IRS favor individualized, evidence-based analysis over generic, off-the-shelf discounts. A percentage pulled from a table, untethered to the specific business, is inconsistent with both Revenue Ruling 59-60 and sound practice. For the broader framework these adjustments fit within, see our overview of business valuation.
What raises and what lowers the discount
The magnitude of any key person adjustment turns on the facts. Factors that increase it include revenue, client relationships, technical expertise, or reputation concentrated in one individual; the absence of a trained successor; no key person insurance; and no employment or non-compete agreement binding that person to the business.
Factors that mitigate it include genuine depth of management and a capable successor; key person life and disability insurance that cushions the financial blow; employment and non-compete agreements that retain the individual and protect the client base; a documented succession or transition plan; and client relationships and processes that are institutionalized rather than personal. A business that has prepared for the loss of its key person is worth more than one that has not.
Key person discount versus personal goodwill
The key person discount is closely related to personal goodwill, and in a Florida divorce the two intersect directly. Florida law excludes an individual’s personal goodwill — value tied to his or her own reputation and continued work — from the marital estate. A key person discount addresses the same economic reality from the valuation side: the more a company’s value depends on one spouse’s personal involvement, the less of that value is transferable enterprise value. An analyst valuing a closely held business in a dissolution must account for both. We address the related goodwill framework in personal versus enterprise goodwill in a Florida divorce and for professional-services firms.
Frequently asked questions
What is a key person discount?
It is a downward adjustment to a business’s value that reflects the risk of over-dependence on one individual whose loss would impair earnings. Revenue Ruling 59-60 recognizes this risk for closely held companies.
How much is a key person discount?
There is no standard percentage. The magnitude depends entirely on the specific business — how central the individual is and what safeguards exist. The most defensible figure comes from measuring the actual financial impact on cash flows, not from applying a fixed rate.
What is the difference between a key person discount and key person insurance?
Key person insurance is a policy the company owns on the individual to offset the financial loss of a death or disability. A key person discount is a valuation adjustment for the underlying risk. They are connected: the presence of adequate insurance is one of the factors that can reduce the discount.
Does Revenue Ruling 59-60 require a key person discount?
The ruling recognizes that the loss of a key manager can depress a company’s value and directs analysts to consider it. Whether an adjustment applies, and how large, is a judgment based on the facts of the specific business.
How does a key person discount apply in a divorce?
It overlaps with personal goodwill. The more a marital business depends on one spouse’s personal relationships and skills, the more of its value is personal rather than transferable — which both supports a key person adjustment and, under Florida law, narrows the portion subject to equitable distribution.
