Crypto is treated as property by the IRS. Short-term gains taxed at ordinary rates, long-term at 0%/15%/20%. This is for estimation only — consult a tax professional.
The IRS treats crypto as property, so every disposal (sell, spend, trade) is a taxable event. Your gain is proceeds − cost basis, and the basis you claim depends on the accounting method: FIFO (first in, first out), average cost, or specific identification of the lots you sell. That choice alone can move your gain by thousands of dollars on the same transaction. Gains held over a year are taxed at the long-term rates (0% / 15% / 20%) stacked on top of your ordinary income, plus a 3.8% Net Investment Income Tax once your total income passes $200,000 (single) or $250,000 (married filing jointly) — exactly how this tool computes your after-tax profit.
You hold two 0.5 BTC lots and sell 0.5 BTC at $68,000. The method you elect changes the cost basis and therefore the taxable gain — before long-term tax rates are applied.
Priya sold 0.5 BTC for $68,000 in 2026. She bought it for $30,000 over a year ago, so the gain is long-term. Her other income is $80,000 and she files single.
To calculate crypto profit: enter your buy price, sell price, and investment amount — the tool shows your profit/loss, ROI percentage, and estimated tax liability.

Calculate your after-tax crypto profit before selling. BTC, ETH, and altcoins. Capital gains tax by state. Free, instant, no signup.
The Crypto Profit Calculator is a free, browser-based tool that calculates your capital gains, tax liability, and after-tax profit when selling cryptocurrency. It supports 13 major coins (Bitcoin, Ethereum, Solana, and more), distinguishes between short-term and long-term gains, factors in the Net Investment Income Tax (NIIT) of 3.8% for high earners, and applies state capital gains tax for all 50 states. No signup, no data upload.
This calculator is for crypto investors, traders, and anyone who has sold or plans to sell cryptocurrency for a profit. Whether you trade on Coinbase, Binance, Kraken, or use DeFi platforms, you need to know your tax liability before tax season. The IRS treats crypto as property — every sale is a taxable event.
Enter your coin, purchase price, sale price, holding period, filing status, ordinary income, and state. The calculator: (1) Determines if your gain is short-term (held 365 days or less, taxed at ordinary income rates) or long-term (held 366+ days, taxed at preferential 0%/15%/20% rates). (2) Adds NIIT (3.8%) if your modified AGI exceeds $200,000 (single) or $250,000 (married). (3) Applies your state's capital gains tax. (4) Shows your effective rate and net proceeds after tax.
You bought 1 BTC at $42,000 and sold it at $65,000 after holding for 400 days (long-term): • Gain: $23,000 • Federal LTCG (15% bracket): $3,450 • NIIT (if MAGI > $200K): $874 • California state tax (~9.3%): ~$2,139 • Total tax: ~$6,463 (28.1% effective rate) • Net proceeds after tax: ~$16,537 If you had sold after only 300 days (short-term), the same $23,000 gain would be taxed at ordinary rates — costing thousands more.
The IRS treats cryptocurrency as property. Selling crypto for fiat (USD), trading one crypto for another, or using crypto to purchase goods/services all trigger a taxable event. Short-term gains (held 365 days or less) are taxed at ordinary income rates (10%-37%). Long-term gains (held 366+ days) are taxed at preferential rates (0%, 15%, or 20%).
Short-term gains (crypto held 365 days or less) are taxed at your ordinary income tax rate, which ranges from 10% to 37% in 2026. Long-term gains (held 366+ days) are taxed at 0%, 15%, or 20%, depending on your income. For most taxpayers, holding for over a year cuts the federal tax rate roughly in half.
You can use capital losses to offset capital gains dollar-for-dollar. If your losses exceed your gains, you can deduct up to $3,000 per year against ordinary income ($1,500 if married filing separately) and carry forward remaining losses to future years. This is called tax-loss harvesting.
The NIIT is a 3.8% surtax on investment income (including crypto gains) for taxpayers with modified AGI above $200,000 (single) or $250,000 (married filing jointly). It applies to the lesser of your net investment income or the amount by which your MAGI exceeds the threshold.
Yes. Starting in 2026, crypto exchanges issue Form 1099-DA to report your transactions to the IRS. You must report all crypto sales on Form 8949 and Schedule D, even if you sold at a loss. Failing to report can result in penalties, interest, and audit.
