The information below may be useful when using this calculator.

  • An asset sold within a year of purchase is typically taxed as ordinary income (23% on average) and called a short-term gain/loss. This may be about twice the tax rate you pay on long-term sales, and is 10 to 37% at the time of this writing, depending on your tax bracket.
  • An asset held longer than a year is typically subject to long-term capital gains taxes, typically 15%. These are 0 to 20% at the time of this writing—often roughly half the short-term rate.
