Crypto Tax Estimator Calculator

About this calculator

Selling, swapping or spending cryptocurrency generally triggers a capital-gains tax event: taxable gain = proceeds − cost basis − transaction fees, where cost basis is what you originally paid for the coins (including any fees at purchase) and proceeds is what you received on the sale. Whether that gain is taxed at short-term (ordinary income) or long-term (typically lower) capital gains rates in the US usually depends on whether you held the asset for more or less than a year.

Crypto traders and their accountants use this kind of estimate throughout the year — not just at tax time — for tax-loss harvesting decisions (selling a losing position to offset gains elsewhere) and to avoid an unpleasant surprise when a big trade turns out to owe more tax than expected. It's especially useful for anyone who's made several trades in a coin bought at different times and prices, since cost basis has to be tracked per-lot rather than as one average number.

This calculator takes your proceeds, cost basis, fees and tax rate and returns the estimated taxable gain and after-tax amount.
