A company is valued at $1,000,000. You hold 20% of the shares. Your stake is not worth $200,000, and depending on who holds the other 80%, it might be worth closer to $100,000.
That gap is the minority discount, and it is the single most misunderstood number in private company shareholdings. People discover it at the worst possible moment — mid-dispute, mid-divorce, or at the point they finally try to sell.
This article explains where the discount comes from, why it is really two separate discounts rather than one, and how the size of your stake maps onto what you can actually make the company do. You will also see the indicative ranges applied in practice, and the three situations that override all of them.
Start with what the term means, because the definition contains the reason.
What a minority interest is
A minority interest is a shareholding that does not give its holder control of the company, conventionally any holding below 50% of the issued share capital. Holding a minority interest means the shareholder cannot unilaterally decide dividends, appoint or remove directors, or force a sale of the business. The value of a minority interest is therefore lower than its pro-rata share of the whole-company value, because a buyer is purchasing an income stream they cannot direct.
The phrase to hold on to is cannot direct. Every pound of discount traces back to it.
It is two discounts, not one
This is where most explanations flatten something important. Two distinct deductions are usually at work, and they are argued separately by professionals:
Discount for lack of control. You cannot set dividend policy, cannot appoint directors, cannot approve or block a sale of the business. Your return depends on decisions other people make.
Discount for lack of marketability. Even at a fair price, you may not be able to sell. Private company shares have no exchange, the articles usually impose pre-emption rights giving existing shareholders first refusal, and in the worst case there is simply no buyer at any price.
Why the distinction matters: they are not always both present, and they do not always move together. A 45% stake in a company with a well-drafted shareholders' agreement including an exit mechanism suffers a control discount but a modest marketability one. A 5% stake in a company whose articles let the board refuse any transfer suffers heavily on both.
Here is the thing most minority holders miss. The marketability half is often the larger of the two, and it is the half you can sometimes fix — by negotiating drag-along, tag-along or put option rights into a shareholders' agreement while relations are still good.
The five thresholds that actually matter
Discounts step down at the points where your voting power changes what you can do. In UK company law those points are set by statute; in the US they are set by the certificate of incorporation, the operating agreement or state law. Check which applies to you, because the thresholds move.
The common pattern:
| Holding | What it lets you do | What it cannot do |
|---|---|---|
| 75% or more | Pass special resolutions — change the articles, change share capital, wind up the company | Little; this is near-total control |
| Over 50% | Pass ordinary resolutions — appoint and remove directors, control day-to-day direction | Cannot pass special resolutions alone |
| Exactly 50% | Block anything | Pass nothing without the other half agreeing |
| 25% + 1 to 49% | Block special resolutions — genuine negotiating leverage | Cannot control ordinary business at all |
| Under 25% | Vote, receive dividends if declared, inspect certain records | Neither control nor block anything |
Notice the fourth row. A holding just over 25% is worth disproportionately more than one just under it, because crossing that line converts a passive stake into a blocking minority. The holder cannot make the company do anything — but they can stop it changing its articles, and that is a seat at the table.
That single threshold explains why valuation practice treats a 26% holding and a 24% holding so differently, despite two percentage points separating them.
Indicative discount ranges
Now the numbers everyone scrolls for. Read the caveat first, because it is doing real work.
There is no fixed schedule. The ranges below are what practitioners commonly apply as a starting position, and they are routinely departed from in both directions on the facts of a specific case. Any valuer who applies them mechanically without examining the shareholder register, the articles and the dividend history is not doing the job.
| Size of holding | Indicative discount | Driven mainly by |
|---|---|---|
| Above 75% | 0% – 10% | Near-complete control; little to discount |
| 50% + 1 to 75% | 10% – 15% | Controls ordinary business, not special resolutions |
| Exactly 50% | 15% – 25% | Deadlock risk; depends entirely on who holds the other half |
| 25% + 1 to 49% | 30% – 40% | No control, but retains blocking power |
| 10% to 25% | 45% – 50% | No control, no blocking power |
| Below 10% | 50% – 75% | Minimal rights; often no realistic market |
Two situations inside that table deserve their own explanation.
The 50% deadlock. Where two shareholders each hold exactly half, neither can pass anything, and a large discount around the top of that band may be justified. But where one 50% holding faces a scattered collection of small shareholders, that holder is effectively in control in practice, and the discount falls sharply. And if the articles give one of them a casting vote, they are not a minority shareholder at all — they hold control, and should be valued accordingly.
The strategic stake. Occasionally a minority holding is worth more than pro-rata, not less. If your stake is the piece that takes another shareholder over 50% or over 75%, you are selling control, and control has a price of its own.
The three things that override everything above
Before applying any discount, check these. In order:
- The articles of association. If they specify how shares are to be valued on transfer, that mechanism binds — whatever general practice says.
- The shareholders' agreement. It frequently contains a valuation formula, a nominated valuer, or an express instruction that no minority discount applies. That last clause is common and decisive.
- The purpose of the valuation. Court-directed valuations in shareholder disputes and matrimonial proceedings frequently apply reduced discounts or none at all, particularly where the minority holder was excluded from the business unfairly. The commercial arithmetic and the arithmetic a court will accept are not always the same.
That third point catches people out constantly. A valuation prepared for a friendly internal buyout and one prepared for a contested unfair-prejudice petition can differ substantially on the same shareholding, on the same date, and both be right for their purpose.
Which is why the first question in any minority valuation is not "how big is the stake" but "what is this valuation for".
Where our toolkit fits, and where it does not
Every discount above is applied to something: the whole-company value. You cannot discount a number you do not have.
That base figure is what our Toolkit Pro platform produces. Its Business Valuation view sits inside the financial forecast and shows three whole-entity valuations side by side — discounted cash flow, an earnings multiple applied to forecast EBITDA, and net asset value — each recalculating as you adjust the required return, growth rate and multiple. Building that forecast properly is covered in our guide to adjusted EBITDA multiples, and the financial forecast is where the underlying numbers go.
Be clear about the limit, though. The tool values the company as a whole. It does not read your articles, weigh your shareholder register, or select a minority discount — and it should not pretend to, because that percentage is a judgement made on documents and circumstances, and it is the number the other side will contest.
If the stake matters enough to argue about, have the discount reasoned and written down by someone independent.
