Apply a capital gains tax rate to a gain to estimate tax and after-tax proceeds.
Overview
Capital gains tax applies when you sell an asset for more than your basis. The rate depends on holding period, income, and jurisdiction.
Enter the gain and an applicable tax rate percent. The calculator returns estimated tax and after-tax gain.
This is a planning estimate—not a filing engine. Long-term vs short-term rates, state tax, and deductions can change the real bill.
Steps
Sale proceeds minus cost basis (simplified).
Federal (and state if combining) rate you expect.
Review estimated tax and after-tax gain.
Test long-term vs short-term rate scenarios.

Math
estimatedTax = gain × (taxRate / 100); afterTax = gain − estimatedTax
Tax is the gain times the rate. After-tax gain subtracts that tax.
