About Crypto Tax Calculator
The Crypto Tax Calculator estimates the capital gain and tax when you sell or dispose of a cryptocurrency. You enter the proceeds you received and the cost basis you originally paid, and the tool subtracts the basis from the proceeds to find the gain. It then applies the capital gains tax rate you provide, charging tax only when the gain is positive.
Unlike a receipt-based income calculation, this tool focuses on the disposal event: the difference between what you sold for and what the asset cost you. If the proceeds are lower than the basis the gain is negative, so the tool reports no tax rather than a refund. The tax rate is a figure you enter yourself, letting you model short-term or long-term rates as needed. The result is a clear estimate of the taxable gain and the tax that gain produces.
Formula & Mathematical Calculation
Capital gain = Sale proceeds − Cost basis | Capital gains tax = Gain (only when positive) × Tax rate ÷ 100
Calculation Example
Example: Selling for proceeds of $18,000 against a cost basis of $10,000 gives a gain of $18,000 − $10,000 = $8,000. At a capital gains rate of 15%, the tax is $8,000 × 15 ÷ 100 = $1,200.
