Calculation path

The page creates an adjusted cost basis, subtracts it and selling costs from proceeds, applies entered offsets only to a positive gain, then applies your rate.

Calculation path

Gain = sale proceeds - selling costs - adjusted basis. Taxable gain = positive gain - entered exemptions or usable losses. Estimated tax = taxable gain x entered effective rate.

What you provide

What you receive

What you receive

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

This is intentionally jurisdiction-neutral. Do not use the default rate for filing; special rates, holding periods, residency, indexation, exemptions, surcharge, and loss rules can materially change tax.
