How It Works: Calculate your tax liability on investment profits. Tax rates depend on how long you held the asset and your income level.

Key Inputs:
  • Purchase & Sale Price: Your cost basis and selling price.
  • Annual Income: Determines your tax bracket.
  • Holding Period: Less than 1 year = short-term, 1+ years = long-term.
  • Filing Status: Single, married, or head of household.


Tax Rates (2024):
  • Long-Term: 0%, 15%, or 20% based on income (favorable rates).
  • Short-Term: Taxed as ordinary income at your marginal rate (10%-37%).


Strategy: Holding assets for 1+ year can significantly reduce your tax burden.

Capital Gains Tax Strategies

Taxes can eat up a huge portion of your investment returns. Understanding the difference between Short-Term and Long-Term capital gains is the first step to keeping more of what you earn.

The One-Year Rule

The magic number is 366 days. If you hold an asset for at least a year and a day, you qualify for long-term capital gains rates (0%, 15%, or 20%), which are significantly lower than ordinary income tax rates (up to 37%).

Tax Loss Harvesting

Offset Your Gains

Did you lose money on a different investment? You can use those losses to offset your gains dollar-for-dollar. If your losses exceed your gains, you can even use up to $3,000 of excess loss to offset your regular income.

Net Investment Income Tax (NIIT)

High earners may face an additional 3.8% tax on investment income if their modified adjusted gross income (MAGI) exceeds certain thresholds ($200k for single, $250k for married). This calculator estimates standard capital gains but verify if NIIT applies to you.
