What it means
Every asset you hold has a cost basis, meaning what you paid for it plus the costs of buying it, and a current market value. When market value sits above cost basis and you still own the asset, the difference is an unrealized gain.
The distinction between paper value and cash matters more than people expect. A business showing a large unrealized gain on an investment portfolio cannot pay wages with it, and a founder holding shares worth millions on paper may have very little spendable money in the bank.
How the gain is treated in the accounts depends on what the asset is and why it is held. Trading securities are typically marked to market with the movement flowing through the income statement, while other holdings may sit at fair value with the movement parked in other comprehensive income until disposal.
Tax generally follows the sale rather than the price movement. In most systems the charge arises when you dispose of the asset and the gain becomes actual, which is why timing a disposal either side of a tax year end is a routine piece of planning.
Unrealized gains also introduce wobble into reported profit. A company holding volatile assets can post a strong quarter on price movements alone, so analysts often strip these amounts out to see how the operating business really performed.
In practice
Real-world examples
Example 1
A family restaurant group bought its building for $1,200,000 and a recent valuation puts it at $2,100,000. The $900,000 unrealized gain strengthens the balance sheet under a revaluation policy and helps in refinancing discussions, but no cash has changed hands and the mortgage payments are unaffected.
Example 2
An early employee at a software company holds 40,000 shares bought at $0.50 each and valued at $9.00 in the latest funding round. That is an unrealized gain of 40,000 x $8.50 = $340,000. She cannot spend it, and if the next round prices lower the paper gain shrinks with it.
Example 3
A manufacturer's treasury team reports a $460,000 unrealized gain on its bond portfolio after interest rates fall. The finance director shows it separately from operating results in the board pack, because the gain says nothing about how the factories performed that quarter.
Think of it
Imagine you own a rare comic book you bought for 10 pounds. A collector offers to buy it for 100 pounds today, but you keep it on your shelf. You have a 90 pound paper profit, but no actual cash in your pocket.
Formula
Calculation
Unrealized Gain = Current Market Value - Cost Basis, or per unit: (Current Price per Unit - Purchase Price per Unit) x Units Held.
A manufacturer invests spare cash in 20,000 listed shares at $12.50 each. Cost basis = 20,000 x $12.50 = $250,000. Two years later the shares trade at $18.75, so market value = 20,000 x $18.75 = $375,000. The unrealized gain is $375,000 - $250,000 = $125,000, which is $125,000 / $250,000 = 50% of the original cost. Nothing has been sold, so no cash has arrived and, in most tax systems, no tax is payable yet.Case study
Seen in the real world
Larkspur Instruments is an invented scientific equipment maker used here as an illustrative case. Sitting on surplus cash after a strong two years, its board placed $1,500,000 into a portfolio of listed shares. Within eighteen months the portfolio was worth $2,250,000, an unrealized gain of $750,000, and the chief executive began describing the company as having "$750,000 of extra profit" in management meetings.
The finance director pushed back. She rebuilt the board pack to show operating profit and investment movements on separate lines, and added a note stating plainly that the gain was unrealized and reversible. Six months later a market correction cut the portfolio to $1,725,000, leaving an unrealized gain of only $225,000.
Because the board had never treated the paper gain as spendable, no commitments had been made against it. The company trimmed the position, banked part of the remaining gain and set a policy limiting investment holdings to cash it did not expect to need within three years.
Watch out
Common mistakes
- Committing to spending against an unrealized gain, when the value can fall before anything is sold and the cash never arrives.
- Assuming tax becomes payable the moment the value rises, when most systems tax the gain only on disposal.
- Comparing this year's profit with last year's without noticing that a large slice of it came from price movements rather than trading.
Questions
People also ask
Is an unrealized gain the same as a paper profit?
Yes, the two terms describe the same thing, a rise in value on an asset you still hold.
Do unrealized gains always show up in the income statement?
No, it depends on the asset class and accounting policy, with many gains recorded in other comprehensive income instead.
What turns an unrealized gain into an actual one?
Selling or otherwise disposing of the asset, at which point the difference between proceeds and cost basis becomes locked in.
