Unrealized vs realized

This tool marks your stack to spot. Gains become taxable events when you dispose of crypto under common US rules—confirm with a professional.

Cost basis hygiene

Enter total USD spent (or basis) for the BTC amount shown. Mixed lots, gifts, and transfers need software like Koinly or CoinTracking—see our tax desk.

Sources & methodology

Factual claims cite primary documentation. Interpretation and calculator assumptions are labeled separately so you can verify the source yourself.

  • Source: IRS — Digital assets — The IRS treats digital assets as property for federal tax purposes; selling, exchanging, or otherwise disposing of crypto can be a taxable event.

    GetFreeBit analysis: This calculator shows unrealized mark-to-market only. It does not apply lot methods (FIFO/HIFO), income classifications, or form mappings—use tax software and a qualified preparer for filing.

Examples

  • Mark 0.1 BTC bought for $4,000 against today’s spot.
  • Sanity-check PnL % before exporting trades to tax software.

FAQ

How do I calculate Bitcoin profit?
Multiply BTC held by live USD spot, subtract your cost basis. Positive is unrealized gain; negative is unrealized loss.
Is this a tax calculator?
No. It ignores lot methods, fees, and income classifications. Use dedicated crypto tax tools for filing.
