A realized gain or loss arises when an asset or position is sold, settled, exchanged, or otherwise disposed of relative to the relevant basis.
A realized gain or loss arises when an asset or position is sold, settled, exchanged, closed, or otherwise disposed of for more or less than the relevant basis. A positive result is often called a realized profit. The calculation may use investment cost basis, tax-adjusted basis, or accounting carrying amount depending on the question being answered.
Realization does not always mean the same amount is immediately recognized in accounting income, taxable income, or cash available to spend. Those outcomes depend on the asset, transaction, reporting framework, tax law, and costs.
For a straightforward investment sale:
Net proceeds generally reflect the value received less selling costs included in the chosen calculation. Cost basis can include acquisition costs and later adjustments.
For financial-statement disposal accounting:
For a U.S. federal tax sale or exchange, a common starting relationship is:
The same transaction can produce different answers because carrying amount, investment cost basis, and adjusted tax basis need not be equal.
An investor buys 100 shares at $40 each and pays a $10 acquisition commission:
The investor later sells 60 shares for $55 each and pays a $12 selling fee:
If all shares came from the same purchase, the allocated basis is:
The realized gain on the 60 shares is:
The remaining 40 shares retain $1,604 of basis. Their later market-price changes remain unrealized until another realization event, although an accounting framework may recognize fair-value changes before sale.
Assume a company, rather than an individual investor, carried the 60 shares at $3,240 immediately before selling them and had already recognized prior fair-value gains in income. Its disposal-period accounting gain would be:
The $48 disposal-period accounting gain is not the same as the $882 lifetime gain measured from original investment cost. Much of the economic change had already entered accounting income through earlier fair-value remeasurement.
| Term | Core question | Important boundary |
|---|---|---|
| Unrealized gain or loss | How has value changed while the position remains open? | Can still be recognized in earnings or OCI under fair-value accounting |
| Realized gain or loss | What gain or loss arises from a sale, settlement, or other realization event? | Does not by itself determine accounting or tax treatment |
| Recognized accounting gain or loss | What amount enters the financial statements and where? | Depends on measurement, derecognition, hedging, and presentation rules |
| Tax gain or loss | What amount enters the tax computation? | Depends on jurisdiction, taxpayer, asset, basis, character, and special rules |
| Cash profit or loss | What cash was received or paid? | Can differ because of noncash consideration, financing, timing, and costs |
It is incorrect to say that every unrealized gain stays outside net income. Many financial instruments are remeasured through profit or loss while still held.
For investment analysis, basis may start with purchase price plus eligible transaction costs. Reinvested distributions, return of capital, corporate actions, transfers, foreign-currency translation, or prior sales can change the per-unit amount.
A company’s carrying amount can reflect depreciation, amortization, impairment, fair-value changes, foreign exchange, or another measurement basis. The gain or loss on derecognition compares proceeds with that carrying amount.
Tax basis follows the applicable tax rules. It can differ from both original cost and book carrying amount because of depreciation methods, nondeductible costs, wash-sale or replacement-property rules, gifts, inheritance, reorganizations, and other adjustments.
Derivatives, short sales, partnership interests, debt instruments, digital assets, and foreign-currency transactions can require specialized calculations. A simple sale-price-minus-purchase-price formula may not be sufficient.
When identical units were acquired at different dates and prices, the realized amount depends on which units are treated as sold. Possible methods include specific identification, first-in first-out, or average basis where permitted.
Example:
| Lot | Units | Cost per unit |
|---|---|---|
| Lot A | 50 | $20 |
| Lot B | 50 | $35 |
Selling 50 units at $40 produces a gain of $1,000 if Lot A is identified, but only $250 if Lot B is identified, before costs. The transaction proceeds are identical; the basis assignment differs.
The allowed method and documentation depend on the account, asset, jurisdiction, and elections. Broker records should be reconciled with the investor’s own transaction history.
Accounting does not use realization as the sole recognition rule. Depending on classification:
Analysts should reconcile:
For U.S. federal tax purposes, the IRS describes gain or loss from many sales and exchanges as amount realized minus adjusted basis. Classification as ordinary or capital and short- or long-term can affect treatment.
However, a realization event does not always create current taxable recognition. Nonrecognition, deferral, rollover, wash-sale, installment-sale, straddle, related-party, and loss-limitation rules can change timing or deductibility. Other countries use different rules.
Do not infer a tax bill from a brokerage screen labeled realized gain. Tax returns require taxpayer-specific records, currency, basis, character, holding period, elections, and applicable law.
