How to Use the Capital Gains Tax Calculator

A step-by-step guide to calculating your capital gains tax liability

Overview

The Capital Gains Tax Calculator helps you estimate your tax liability when selling assets such as stocks, cryptocurrency, or real estate. The calculator determines whether your gains are short-term or long-term based on holding period and applies the appropriate tax rates based on your income level.

Stocks: Publicly traded company shares
Cryptocurrency: Bitcoin, Ethereum, and other digital currencies
Real Estate: Property, land, or buildings

Step 2: Enter Purchase and Sale Dates

Input the dates when you acquired and sold the asset. The calculator uses these dates to determine:

Short-term gains: Assets held for one year or less (taxed as ordinary income)

Step 3: Enter Financial Details

Provide the following financial information:

Purchase Price (Cost Basis): The original amount you paid for the asset
Sale Price: The amount you received when selling the asset
Annual Income: Your total taxable income for the year (used to determine tax bracket)
