Unrealized Gain
Key Takeaways
- An unrealized gain is a profit on an investment that has not yet been sold
- Unrealized gains are not taxed until the investment is sold and the gain is realized
- They are also called 'paper gains' because they exist only on paper
- Unrealized gains can disappear if the investment's price declines before selling
Definition
An unrealized gain, also called a paper gain, is the increase in value of an investment that has not yet been sold. It represents the difference between the current market price and the original cost basis of an asset when the current price is higher. The gain is "unrealized" because no actual transaction has occurred to lock in the profit.
For example, if you purchased shares at $50 and they are currently trading at $75, you have an unrealized gain of $25 per share. This gain exists only on paper and could increase or decrease as the market price changes. The gain becomes a realized gain only when you actually sell the shares.
Unrealized gains are reported on account statements and brokerage dashboards, but they do not trigger any tax liability in most taxable accounts. This distinction between unrealized and realized gains is fundamental to tax planning and investment strategy.
How It Works
Unrealized gains fluctuate with market prices. If you own 200 shares with a cost basis of $40 and the stock is at $60, your unrealized gain is $4,000 (200 × $20). Tomorrow, if the stock drops to $55, your unrealized gain shrinks to $3,000. If it falls below $40, your unrealized gain becomes an unrealized loss.
The key tax advantage of unrealized gains is deferral. As long as you hold the investment, no capital gains tax is owed. This allows the full value of the gain to continue compounding. An investor with $10,000 in unrealized gains has more capital working for them than one who sold, paid taxes on the gain, and reinvested the after-tax proceeds.
This tax deferral benefit is one of the strongest arguments for buy-and-hold investing. The longer you defer realizing gains, the more time your money compounds. When gains are eventually realized, long-term capital gains rates (for assets held over one year) are lower than short-term rates, providing another incentive to hold.
Example
You invested $20,000 in an S&P 500 index fund ten years ago. Today, your investment is worth $52,000, giving you an unrealized gain of $32,000. If you sell, you would owe long-term capital gains tax on $32,000. At a 15% rate, that is $4,800 in taxes, leaving you with $47,200. If instead you continue holding, the full $52,000 remains invested and earning returns. Over another 10 years at 10% average returns, the $52,000 could grow to approximately $134,900, whereas $47,200 would grow to only about $122,400 — a $12,500 difference from tax deferral alone.
Why It Matters
Unrealized gains represent the accumulation of wealth without the erosion of taxes. Understanding this concept is essential for making informed decisions about when to sell investments. Selling to realize gains triggers an irreversible tax event that permanently reduces your invested capital.
Tax-efficient investors seek to defer realizing gains as long as possible, using strategies like buy and hold, specific lot identification to minimize gains when selling, and donating appreciated shares to charity (which avoids capital gains tax entirely). The power of tax deferral is one of the most important advantages available to long-term investors.
Advantages
- No tax liability until gains are realized through a sale
- Tax deferral allows full investment value to continue compounding
- Provides flexibility to time sales for optimal tax outcomes
- Appreciated assets can be donated to charity to avoid capital gains entirely
Limitations
- Paper gains can disappear if the investment's price declines
- Unrealized gains may create a false sense of wealth or security
- Large unrealized gains can make investors reluctant to rebalance portfolios
- Cannot be used to offset realized losses for tax purposes until sold
