US CAPITAL GAINS TAX CALCULATOR 2025

HOW TO USE

  1. 1

    Select your filing status — Single, Married Filing Jointly, Married Filing Separately, or Head of Household.

  2. 2

    Enter your ordinary income (wages, salary, business income) before capital gains. This determines where your gains sit in the bracket stack.

  3. 3

    Enter your capital gain amount and choose whether it is long-term (held > 1 year) or short-term (held ≤ 1 year).

  4. 4

    The calculator shows your federal capital gains tax, effective rate, and whether NIIT applies. Use the breakdown chart to see exactly which rate applies to each dollar of your gain.

WORKED EXAMPLE

Sarah is single with $80,000 in wages and a $50,000 long-term capital gain from selling stock in 2025. Her total taxable income is $130,000. The 0% LTCG rate applies up to $48,350 — but her ordinary income of $80,000 already fills that bracket. So her entire $50,000 gain falls in the 15% bracket. Tax = $50,000 × 15% = $7,500. Her MAGI of $130,000 is below the $200,000 NIIT threshold, so no NIIT applies. Effective rate on the gain: 15%.
