Home Sale Cost Basis Calculator
Selling a home can result in either a gain or loss. To figure out how much profit (or loss) you’ve made on the sale, you need to calculate your adjusted cost basis — a key number used to determine whether you owe capital gains tax.
The Home Sale Cost Basis Calculator helps you determine this figure accurately by factoring in:
- Your original purchase price
- Associated buying and selling expenses
- Capital improvements made to the property
Knowing your cost basis is essential if you plan to report a home sale on your taxes, especially when your profit exceeds the IRS exclusion limits.
📊 Formula (Plain Text)
Here’s how to calculate your adjusted cost basis:
Adjusted Cost Basis = Purchase Price + Purchase Expenses + Capital Improvements + Selling Expenses
Where:
- Purchase Price is the amount you paid for the home
- Purchase Expenses include legal fees, title insurance, and closing costs
- Capital Improvements are upgrades that add value or extend the home’s life (not repairs)
- Selling Expenses include agent commissions, legal fees, staging, and closing costs at sale
✅ How to Use the Calculator
- Enter the Original Purchase Price
This is what you paid for the home when you first bought it. - Enter Purchase Expenses
Include all associated costs such as transfer taxes, title insurance, and legal fees. - Enter Capital Improvements
List only value-adding renovations (e.g. new roof, kitchen remodel, home extensions). - Enter Selling Expenses
Include real estate agent fees, escrow fees, title fees, etc. - Click “Calculate”
The tool will show your adjusted cost basis — useful for calculating capital gains.
🧮 Example Calculation
Let’s say you:
- Bought a home for $300,000
- Paid $5,000 in purchase expenses
- Spent $20,000 on capital improvements
- Paid $15,000 in selling expenses
Then:
Adjusted Cost Basis = 300,000 + 5,000 + 20,000 + 15,000 = $340,000
If you sell your home for $450,000, your capital gain would be:
$450,000 – $340,000 = $110,000
If you qualify for the IRS exclusion (up to $250,000 single / $500,000 married), this gain may be tax-free.
