An unrealized gain or loss is the increase or decrease in the value of an asset or open position before it has been sold, settled, or otherwise realized. It is often called a paper gain or loss, but it can still affect portfolio value, collateral, financial statements, and risk even when no sale proceeds have been received.
Paper profit is the informal positive version of this concept. The phrase does not identify the valuation method, accounting treatment, tax treatment, liquidity, or costs, so formal analysis should use the more precise unrealized gain or loss label and state the comparison basis.
Key Takeaways
- For a long asset, an unrealized gain is positive when the current measurement exceeds the relevant cost or carrying amount; short positions use the opposite price relationship.
- The comparison amount depends on context. A brokerage view may use trade cost, tax reporting may use adjusted basis, and financial statements may use a prior carrying amount.
- Unrealized does not mean imaginary or irrelevant. The value can affect net worth, margin capacity, covenants, reported earnings, or other comprehensive income.
- A gain can shrink or reverse before realization, and a quoted price may not be obtainable for the full position.
- Realization and tax recognition are related but distinct concepts. Some realized gains are deferred or excluded, while some open positions are taxed or settled under mark-to-market or deemed-disposition rules.
- Accounting treatment depends on the asset, classification, measurement basis, reporting framework, and any hedge-accounting designation.
- The term describes value change, not cash income, investment performance after all costs, or a recommendation to hold or sell.
Basic Calculation
For a simple long position:
$$
\text{Unrealized gain or loss}
=
\text{Current marked value}
-
\text{Comparison amount}
$$
If the position contains Q identical units acquired at unit price P_0 and currently marked at P_t:
$$
\text{Unrealized gain or loss}
=
(P_t-P_0)\times Q
$$
This simplified formula excludes commissions, accrued income, distributions, taxes, foreign-exchange effects, basis adjustments, and prior accounting remeasurements. Those items may need to be included or shown separately depending on the purpose of the calculation.
Worked Example: An Open Stock Position
Assume an investor buys 100 shares at $40 per share and pays a $10 commission. The shares later trade at $46.
Price-Only View
$$
(\$46-\$40)\times100=\$600
$$
The position has a $600 price-only unrealized gain.
Cost-Inclusive View
If the reporting view includes the acquisition commission in the comparison amount:
$$
\text{Cost}=100\times\$40+\$10=\$4{,}010
$$
$$
\text{Marked value}=100\times\$46=\$4{,}600
$$
$$
\text{Unrealized gain}=\$4{,}600-\$4{,}010=\$590
$$
If the price falls to $37 before sale, the same cost-inclusive view becomes:
$$
100\times\$37-\$4{,}010=-\$310
$$
The earlier gain has reversed into an unrealized loss. No sale was required for the investor’s economic position to deteriorate.
Unrealized vs. Realized vs. Recognized
| Term | Core meaning | Typical evidence | Important caution |
|---|
| Unrealized gain or loss | Value change while the asset or position remains open | Market quote, valuation model, position record, carrying amount | The mark may change and may not equal executable proceeds |
| Realized gain | Gain determined after a sale, exchange, settlement, expiry, or other realization event | Trade confirmation, settlement record, disposition agreement | Realized does not always mean immediately taxable |
| Recognized gain or loss | Amount included under the applicable tax or accounting rules | Return, ledger, tax schedule, accounting policy | A rule may defer, exclude, reclassify, or accelerate recognition |
| Cash proceeds | Money received from a transaction | Bank and settlement records | Proceeds are not the same as profit because basis and costs remain |
A position can have a large unrealized gain without producing cash. Conversely, a sale can generate substantial cash proceeds but little gain if the asset’s basis is nearly as high as the sale amount.
Choosing the Correct Comparison Amount
The word cost can hide several different measures:
- Trade cost: execution price multiplied by quantity.
- Total acquisition cost: trade cost plus commissions or directly attributable transaction costs where included.
- Adjusted tax basis: tax-specific basis after applicable additions, reductions, allocations, distributions, depreciation, elections, or other adjustments.
- Accounting carrying amount: amount recognized in the financial statements before the latest remeasurement.
- Prior period mark: value used to measure the current period’s change rather than the lifetime gain.
Suppose shares originally cost $4,000, but a non-taxable distribution reduces their tax basis to $3,700. At a current value of $4,600, the brokerage’s simple price view may show $600, while the tax-basis comparison could show $900 before transaction costs and other rules. Neither number should be labeled without stating its basis.
Portfolio and Brokerage Statements
A brokerage platform may display unrealized gain or loss by tax lot, position, account, or currency. Before relying on the number, check:
- whether commissions and fees are included;
- which tax lot or average-cost method is used;
- whether dividends, interest, and return-of-capital distributions are separate;
- how corporate actions and transferred positions affected basis;
- whether prices are live, delayed, closing, bid, midpoint, or modeled;
- how foreign-currency positions are translated;
- whether accrued interest is included for bonds;
- whether options, short positions, or futures use a different convention; and
- whether the displayed basis is informational or confirmed for tax reporting.
An unrealized gain is not the same as total return. Total return may include reinvested distributions, income, fees, and cash flows that a price-only gain omits.
Financial-Statement Treatment
Companies do not report every unobserved market increase as an asset or gain. Treatment depends on whether the asset is recognized, how it is classified, and whether the applicable accounting standard measures it at cost, amortized cost, fair value, or another amount.
For financial instruments measured at fair value, a period’s unrealized change may be presented in:
- profit or loss;
- other comprehensive income;
- another component required by a specific hedge, foreign-currency, insurance, or instrument rule; or
- disclosures rather than as a recognized current-period market gain for an item not measured at fair value.
Under IFRS 9, for example, financial-asset classification helps determine whether subsequent changes are measured through profit or loss, through other comprehensive income, or at amortized cost. The label “unrealized” alone does not determine the financial-statement line.
This investment-market meaning is also different from Unrealized Intercompany Profit on an intragroup sale. In consolidation, that term refers to profit eliminated because the asset remains within the reporting group rather than being sold to an external party.
Tax Treatment Is Jurisdiction-Specific
For a conventional taxable investment, tax law often calculates gain or loss when a sale, exchange, or other disposition occurs. The U.S. Internal Revenue Service, for example, generally compares the amount realized on a disposition with adjusted basis.
That general pattern has important exceptions. Depending on jurisdiction and instrument, tax consequences can arise through:
- mark-to-market regimes for specified traders, dealers, funds, or contracts;
- deemed dispositions after a change in residence, death, transfer, or other event;
- constructive-sale or wash-sale rules;
- distributions that change basis;
- foreign-currency rules;
- partnership, trust, fund, or pass-through allocations;
- elections that defer or accelerate recognition; or
- account-specific exemptions or deferrals.
Holding period can affect the character or rate applied when a gain is recognized, but an open gain should not automatically be labeled short-term or long-term without reference to the governing rule and a realization event.
The distinction between realized and recognized matters. A transaction can realize an economic gain while a tax rule defers recognition, and some regimes can recognize changes before a conventional sale.
Open Positions, Shorts, and Derivatives
The long-position formula does not apply unchanged to every instrument.
For a simple short sale marked before closeout:
$$
\text{Unrealized short P/L}
=
(\text{Short-sale price}-\text{Current buyback price})\times Q
$$
Borrow fees, distributions owed to the lender, margin interest, and closeout costs reduce the economic result.
Futures can be marked to market and settled through daily variation margin, so an economically open exposure may generate daily cash flows and recognized gains or losses. Options require attention to premiums, contract multipliers, exercise, assignment, expiry, volatility, and valuation inputs. For these positions, Open Trade Equity may be the more precise trading-account measure.
Liquidity and Valuation Risk
An unrealized amount is only as reliable as the mark behind it.
- A quoted price for a small trade may not be available for a large block.
- A stale last trade can differ from current executable bids and offers.
- Thinly traded securities can have wide spreads.
- Private assets and complex instruments depend on valuation models and assumptions.
- Forced sales may occur at discounts during market stress.
- Foreign-exchange movements can change home-currency gain even when the local asset price is unchanged.
- Credit deterioration can make a carrying value difficult to recover.
For a concentrated or illiquid position, analysts should test exit size, timing, transaction costs, market depth, valuation uncertainty, and financing requirements rather than treat the displayed gain as cash-equivalent wealth.
Common Mistakes
- Calling an unrealized gain cash income.
- Assuming every unsold gain is untaxed in every jurisdiction.
- Treating realized and recognized as interchangeable.
- Using purchase price when adjusted basis or carrying amount is required.
- Ignoring commissions, accrued income, distributions, corporate actions, and currency translation.
- Describing an open gain as short-term or long-term before applying the relevant tax rule.
- Assuming a company records every market-value increase in net income.
- Comparing broker statements that use different lot, price, currency, or fee conventions.
- Treating a model value for an illiquid asset as guaranteed sale proceeds.
- Holding or selling solely because a position shows a gain or loss, without considering objectives, risk, liquidity, taxes, and alternatives.

FAQs
When does an unrealized gain become realized?
Usually when a sale, exchange, settlement, expiry, exercise, or other realization event fixes the transaction result. The exact event depends on the asset, contract, accounting framework, and tax law.
Are unrealized gains taxable?
Often not before disposition for a conventional investment, but there are important exceptions, including mark-to-market and deemed-disposition regimes. Tax treatment depends on jurisdiction, taxpayer, account, instrument, and transaction.
Does an unrealized gain appear in net income?
Sometimes. Financial-statement treatment depends on the asset and accounting classification. A fair-value change may enter profit or loss, other comprehensive income, or neither in the current period.
Is an unrealized loss harmless until an asset is sold?
No. It reduces current economic value and can affect collateral, margin, covenants, liquidity, or financial reporting. The value may recover, decline further, or be difficult to realize at the displayed mark.
