What Is a Capital Gain?

A capital gain is the profit you generally earn when you sell an investment for more than your adjusted cost basis. If you sell it for less than your adjusted cost basis, you generally have a capital loss. Capital gains commonly apply to investments such as stocks, ETFs, mutual funds, bonds, cryptocurrency, and certain real estate transactions.

Our Capital Gain Calculator helps you estimate your gain or loss by comparing your purchase price, selling price, purchase fees, and selling expenses. It is designed as an educational tool to help you understand how the calculation works before preparing your tax return.

Simple Example

Suppose you purchased stock for $5,000 and paid a $25 purchase commission. Later you sold the stock for $7,500 and paid a $50 selling commission.

Your estimated calculation would be:

• Purchase Price: $5,000
• Purchase Fees: +$25
• Adjusted Cost Basis: $5,025
• Sale Price: $7,500
• Selling Expenses: −$50
• Net Sale Proceeds: $7,450
