Estimate your capital gain, potential home-sale exclusion, and tax when selling your house.
Enter your house sale information
to estimate your capital gain and tax.
A capital gains on house sale calculator is a free online tool that helps homeowners estimate the potential capital gain when selling a house. By entering your sale price, purchase price, improvements, selling expenses, and other key information, you can get a quick estimate of your gain and potential tax.
Understanding your capital gains on house sale is important for financial planning. This calculator also estimates your potential eligibility for the home-sale exclusion, which can eliminate tax on up to $250,000 (single) or $500,000 (married joint) of gain for qualifying primary residences.
Using this house sale capital gains calculator is straightforward. Follow these steps:
The basic formula for calculating capital gains on a house sale is:
Adjusted Basis = Purchase Price + Capital Improvements + Other Basis Adjustments
Amount Realized = Sale Price − Selling Expenses
Estimated Capital Gain = Amount Realized − Adjusted Basis
Taxable Gain = Estimated Capital Gain − Potential Exclusion
Estimated Tax = Taxable Gain × Estimated Tax Rate ÷ 100
The home-sale exclusion can eliminate tax on up to $250,000 (single) or $500,000 (married joint) of gain for qualifying primary residences.
The home-sale exclusion allows qualifying taxpayers to exclude a portion of the gain from the sale of a primary residence:
This calculator provides an estimate of potential eligibility. Actual qualification depends on your specific circumstances.
To qualify for the home-sale exclusion, you generally must meet the 2-out-of-5-year test:

Routine repairs and maintenance (painting, fixing leaks) do not generally increase basis.
Yes. Selling expenses reduce the amount you realize from the sale, which reduces your capital gain. Common selling expenses include:
No. The standard primary-home exclusion is not automatically available for a second home. Second homes generally do not qualify for the exclusion. Rental and investment properties have different tax treatment, including depreciation recapture. See our Selling Second Home Tax Calculator or Selling Rental Property Tax Calculator for these situations.

Capital gains on a house sale are the profit you make when you sell your house for more than your adjusted basis. It's calculated as: Sale Price − Selling Expenses − Adjusted Basis.
