USA taxes: Does long term capital gains affect your tax bracket for that year?

Question

Or is your tax bracket calculated prior to these gains?
What about short term capital gains?

Answer 1

Long term capital gains are taxed at 15% and do not affect your marginal bracket. Short term CGs are taxed as ordinary income and will affect your marginal rate.

Answer 2

If you tax rate is 10 or 15%, your long term capital gains rate is generally 5%. If you tax rate is over 15%, you long term capital gains rate is 15%. This figured separately from the rest of your income.

Short Term Capital Gains are taxed at your regular tax rate and are included in your income.
