Short-term vs long-term. Short-term gains (held ≤ 1 year) are taxed at your ordinary
rate. Long-term gains are taxed at 0%, 15%, or 20% depending on your total taxable income. This
calculator does not model the 3.8% Net Investment Income Tax (NIIT) for high earners, or state capital
gains treatment (California taxes them as ordinary, for example).
