What it means
In business and finance, standard valuation models often assume you can sell an asset instantly at fair market value. In reality, investors apply valuation discounts to reflect specific limitations.
The most common type is a discount for lack of marketability, used when shares cannot be easily sold on a public stock exchange. Another frequent type is a minority discount, applied when an owner holds less than half the voting power and cannot steer the company direction.
For non-finance managers, understanding these discounts is vital when buying, selling, or gifting equity. If you own a minority stake in a private family firm, your shares are worth less per unit than the whole company divided equally.
This is because a buyer has no control over dividends or strategy and cannot easily cash out. Recognising this helps set realistic expectations during negotiations, shareholder buyouts, or tax assessments.
Practitioners calculate these discounts by looking at historical data, such as private placement studies or restricted stock studies, which compare private transactions to public market prices. While determining the exact percentage requires professional judgment, the core principle is simple: flexibility, control, and liquidity command a higher price, while their absence incurs a penalty.
Imagine selling a custom house in a remote village compared to a flat in central London. Both might have great intrinsic value, but because the remote house takes months to find a buyer, you must lower your asking price.
That price reduction is your valuation discount.
In practice
Real-world examples
Example 1
Tech founder Sarah owns 10% of a private software start-up. When valuing her stake for estate planning, her accountant applies a 25% discount because the shares are non-voting and cannot be sold quickly. If the 10% stake is worth $200,000 before adjustment, the discounted value is $150,000.
Example 2
Manufacturing SME owner Dave wants to sell a 30% minority stake to a silent partner. Because the partner will have no control over daily operations, the partner demands a 20% discount on the standard share price. On a $300,000 headline value, Dave accepts $240,000.
Example 3
Property holding company Oakwood owns commercial real estate through private shares. An external auditor applies a 15% lack of marketability discount to account for the time required to sell physical property assets. On shares carrying a pro rata value of $1,000,000, the reported value falls to $850,000.

Formula
Calculation
Discounted Value = Undiscounted Value x (1 - Discount Rate)
Worked example 1. A private share block is valued at $100,000 before adjustments. A 20% lack of marketability discount is applied.
- Discounted Value = $100,000 x (1 - 0.20)
- Discounted Value = $100,000 x 0.80 = $80,000
Worked example 2. A 30% stake in a private company worth $2,000,000 is valued at $600,000 before discounts. The valuer applies a 15% minority discount and a 10% lack of marketability discount one after the other.
- After the minority discount = $600,000 x (1 - 0.15) = $510,000
- After the marketability discount = $510,000 x (1 - 0.10) = $459,000
- Total reduction = $600,000 - $459,000 = $141,000, or 23.5% of the original value
Some valuers simply add the two percentages to get 25%, which would give $600,000 x 0.75 = $450,000. Both methods are used, so the valuation report should always state which one it applies.Case study
Seen in the real world
This is a fictional, illustrative scenario. GreenLeaf Logistics, a mid-sized regional courier firm, faced a valuation dispute when founder John retired and offered his son Mark a 30% minority share package. An independent financial adviser was brought in to determine the share value for tax purposes. The adviser calculated the total company value at $2,000,000, meaning a straight 30% calculation would equal $600,000. However, because Mark held a minority stake with no voting control and the shares could not be traded on any open exchange, the adviser applied a combined 25% valuation discount.
This was made up of a 15% minority discount and a 10% lack of marketability discount. Consequently, the adjusted value of Mark's shares dropped to $450,000. The adviser documented the evidence behind each percentage, including comparisons with private sale data, so that the tax authority could review the reasoning. Because tax on the transfer is assessed on the discounted value, this realistic adjustment reduced the potential gift tax bill, provided the evidence was accepted. It also ensured the equity transfer complied with regulatory standards.
Watch out
Common mistakes
- Applying arbitrary discount percentages without supporting market evidence or professional guidance.
- Confusing a minority discount with a lack of marketability discount, as they address two distinct risks.
- Failing to apply discounts when required by tax authorities, leading to overpaid asset valuations.
Questions
People also ask
Are valuation discounts only used for tax purposes?
No, while common in estate and gift tax filings, they are widely used in private equity deals, divorce settlements, and shareholder buyouts.
Can a valuation discount ever be zero?
Yes, if an owner holds a controlling stake that can be sold immediately with full liquidity, discounts may not apply.
Who decides the exact discount percentage?
Independent certified business valuators determine the rate based on empirical market studies and company specifics.
