Capital Gains Tax Calculator

About this calculator

This calculator estimates the taxable gain on an asset by subtracting what was originally paid for it, along with any adjustments like fees, from the price it was sold for, then applies a tax rate the user provides to estimate the resulting tax. Because rates, exemptions, and how long an asset was held before selling all affect the outcome and vary by country and by year, the rate itself is left as a user input rather than assumed.

Investors use it after selling stocks, property, or other assets to get a rough sense of the tax impact of that sale, and some use it beforehand to compare how the numbers might look under different holding periods or sale prices before deciding when to sell.
