What this calculator estimates
Estimate gain on a home sale after selling costs, adjusted basis and entered exclusion. The calculation runs locally in your browser and is intended for planning and comparison.
How to use it
Enter the requested values, select Calculate, review the headline result and supporting figures, then change one input at a time to compare another scenario.
How the calculation works
Realized gain equals net sale proceeds minus adjusted basis. The entered exclusion is then subtracted.
Input checklist
The Home Sale Capital Gains Calculator uses the values shown in its form. Before calculating, check each input independently so an incorrect unit or time period does not carry through to the final result.
- Home sale price ($): verify that this value uses the unit, period, and definition shown by the calculator.
- Selling costs ($): verify that this value uses the unit, period, and definition shown by the calculator.
- Original purchase price ($): verify that this value uses the unit, period, and definition shown by the calculator.
- Capital improvements ($): verify that this value uses the unit, period, and definition shown by the calculator.
- Available home-sale exclusion ($): verify that this value uses the unit, period, and definition shown by the calculator.
Practical interpretation
Use the Home Sale Capital Gains Calculator result as the answer to the specific inputs entered, not as a universal value. The calculation currently described on this page is: Realized gain equals net sale proceeds minus adjusted basis. The entered exclusion is then subtracted. Change one important input at a time when comparing scenarios so you can see which assumption actually drives the difference.
Checks before relying on the result
The result depends on the values and units entered. Recheck the inputs and compare the estimate with the real-world source or rule that applies to your situation. Recalculate when a key value changes, and keep the original inputs with the result if you need to reproduce or compare the calculation later.
Important limitations
Ownership/use tests, depreciation recapture and special events can change the exclusion and taxable gain.
