What it means
In business and finance, understanding the difference between paper profits and actual profits is essential for managing cash flow and tax obligations. When your company buys an asset, whether it is property, equipment, or shares in another company, its market value will naturally fluctuate over time.
If the value goes up, you have an unrealised gain. However, this wealth is locked inside the asset and cannot be used to pay staff, buy inventory, or distribute dividends.
A realized gain occurs only when you officially liquidate that asset by selling it. At that exact moment, the profit moves from being a theoretical estimate to a concrete financial transaction recorded in your accounting books.
This distinction matters because tax authorities generally do not tax wealth until it is realised. Once you sell the asset and trigger a realized gain, that profit becomes taxable income or capital gains for that financial period.
For non-finance managers, keeping track of realised gains helps you evaluate the true performance of your business operations and investment strategies. Relying solely on unrealised gains can give a false sense of security, because market values can drop just as quickly as they rise before you ever get a chance to sell.
Realised gains give you tangible funds that you can reinvest back into the core business to fuel future growth.
In practice
Real-world examples.
Example
TechStart Ltd bought shares in a supplier for 10,000 pounds. Two years later, they sold the shares for 15,000 pounds. The sale generated a realised gain of 5,000 pounds.
Example
Oak Furniture bought a delivery van for 20,000 pounds. Four years later, they sold it for 8,000 pounds. Since the book value was 5,000 pounds after depreciation, they recorded a realised gain of 3,000 pounds.
Example
Metro Cafe purchased commercial freehold property for 200,000 pounds. They later sold the building for 260,000 pounds, resulting in a realised gain of 60,000 pounds.
Think of it
“Imagine you own a rare comic book. A collector tells you it is worth 500 pounds, but it cost you 50 pounds. That 450 pound profit is just a guess until you actually hand the comic to a buyer and take their money.
Formula
Calculation
Realised Gain = Selling Price - Purchase Price (Cost Basis)
Example: If your business buys equipment for 10,000 pounds and sells it later for 12,500 pounds, the calculation is 12,500 pounds minus 10,000 pounds, which equals a realised gain of 2,500 pounds.Case study
Seen in the real world.
GreenLeaf Logistics held surplus warehouse equipment that had a historical purchase cost of 50,000 pounds on its balance sheet. Due to rising demand for industrial machinery, the market value increased significantly over three years. Management decided to modernise their fleet and sold the old equipment for 70,000 pounds in cash.
On the income statement, GreenLeaf recorded a realised gain of 20,000 pounds, calculated as the 70,000 pounds selling price minus the 50,000 pounds original cost. This transaction did two important things for the company. First, it injected 70,000 pounds of fresh liquid cash into their bank account to help fund new electric delivery vans. Second, it created a taxable profit of 20,000 pounds that the finance team had to factor into their end-of-year tax planning. The finance manager used this clear separation between operating revenue and asset sales to show the board exactly how much cash was generated from surplus asset disposals.
Watch out
Common mistakes.
- Treating unrealised paper gains as available cash to spend on daily operations.
- Forgetting to include transaction costs or depreciation when calculating the actual purchase cost base.
- Failing to plan for corporation tax liabilities that arise immediately after a gain is realised.
Questions
People also ask.
Are realised gains taxed immediately?
Yes, realised gains are typically recorded in the accounting period when the sale takes place and may be subject to corporation tax or capital gains tax.
What is the opposite of a realised gain?
The opposite is a realised loss, which happens when you sell an asset for less than your original purchase price.
Do I need to report unrealised gains on my tax return?
Generally no. Tax authorities only tax gains once they are realised through a completed sale or disposal of the asset.
