What This Calculator Estimates
This capital gains tax calculator estimates tax on a simplified gain using your purchase price, sale price, and tax rate. It is useful for quick planning before you review country-specific rules, exemptions, and filing details.
Formula / Method Used
This page uses a simple method:
- Taxable gain = Sale price - Purchase price, but not less than zero
- Estimated tax = Taxable gain x Tax rate
Worked Example
If you bought an asset for $10,000, sold it for $16,000, and use a tax rate of 15%, the taxable gain is $6,000 and the estimated tax is $900.
What the Result Means
The main result is the estimated tax on the gain based on your simplified inputs. The detail line shows the taxable gain and the rate used in the estimate.
Common Mistakes
- Ignoring transaction costs, improvements, or basis adjustments.
- Using the same rate for every asset regardless of holding period.
- Assuming capital losses are handled the same way in every country.
- Using this estimate without checking asset-specific tax treatment.
