When you sell an asset such as stocks, bonds, mutual funds, or real estate for a profit within a short period of time, the IRS (or your country’s tax authority) considers it a short-term capital gain. Unlike long-term gains, which often benefit from reduced tax rates, short-term gains are typically taxed at your regular income tax rate.

This makes calculating your short-term capital gains tax liability critical for financial planning. To make this process easier, we’ve created the Short Term Capital Gains Calculator. This tool helps investors, traders, and property sellers quickly estimate how much tax they’ll owe on their profits—saving time and reducing errors.

How to Use the Short Term Capital Gains Calculator

Using the calculator is simple. Just follow these steps:

  1. Enter the Purchase Price (Cost Basis)
    • The amount you originally paid for the asset, including fees and commissions.
  2. Enter the Selling Price
    • The amount you sold the asset for.
  3. Add Any Additional Costs
    • Include brokerage fees, transaction charges, or improvement costs (for property).
  4. Enter Your Income Tax Bracket
    • Short-term gains are taxed at ordinary income rates, so select your tax bracket.
  5. Click “Calculate”
    • The calculator instantly shows your profit (or loss) and the estimated tax due.

Practical Example

Suppose you bought 100 shares of a stock at $40 per share ($4,000 total) and sold them three months later at $55 per share ($5,500 total).

  • Purchase Price: $4,000
  • Selling Price: $5,500
  • Gain: $1,500

If you fall in the 24% tax bracket, your short-term capital gains tax would be:

$1,500 × 24% = $360

The calculator instantly provides this result, saving you from doing the math manually.
