Guide
The capital gains calculator estimates taxable gain, estimated tax, net profit after tax, and net proceeds from an asset sale.
It is useful for rough planning before selling investments, property, business assets, or other appreciated assets.
Enter sale price, cost basis, selling costs, and estimated tax rate. Review taxable gain, estimated tax, net proceeds, and after-tax profit.
Use it as a planning estimate only. Actual capital gains treatment depends on asset type, holding period, jurisdiction, exclusions, and tax rules.
Taxable gain equals sale price minus cost basis and selling costs. Estimated tax equals taxable gain times the entered tax rate. Net proceeds subtract selling costs and tax from sale price.
If the calculated gain is below zero, estimated tax is treated as zero in this simplified model.
Cost basis
The value used to measure gain or loss against sale price.
Taxable gain
The gain amount before tax is estimated.
Net proceeds
Estimated cash left after selling costs and tax.
No. Enter the rate you want to test based on your expected tax treatment.
Cost basis is the amount invested in the asset, adjusted for applicable costs or changes.
This calculator subtracts selling costs from the sale price before estimating taxable gain.
