How to Calculate Crypto ROI (With Tax Implications)

You bought Bitcoin at $30,000. It's now $60,000. You're up 100%, right? Wrong. Uncle Sam wants his cut, and the math is more complex than you think.

The Pain of Tax Surprise

Many crypto investors celebrate gains without accounting for capital gains tax. Short-term trading (holding less than 1 year) can trigger tax rates up to 37%. That $10,000 profit might only net you $6,300 after taxes.

The Hard Way: Manual Spreadsheet Hell

Tracking every crypto purchase, sale, and trade across multiple exchanges is a nightmare. Each crypto-to-crypto swap (Bitcoin to Ethereum) is a taxable event. Miss one transaction, and the IRS will notice.

Frequently Asked Questions

What's the difference between short-term and long-term crypto gains?

Short-term gains (held less than 1 year) are taxed as ordinary income at your full tax bracket (10-37%). Long-term gains (held 1+ years) qualify for preferential capital gains rates: 0% if you're in the 10-12% bracket, 15% for most middle-income earners, and 20% for high earners. Holding longer saves massive tax.

Do I owe taxes if I haven't sold my crypto?

No, you only owe capital gains tax when you sell (or trade) your crypto. Unrealized gains are not taxable. However, crypto-to-crypto trades (e.g., Bitcoin to Ethereum) ARE taxable events.

When are crypto taxes due?

If you made significant gains, you may owe quarterly estimated taxes (April, June, September, January) to avoid IRS penalties. Use our calculator to estimate your tax liability and plan ahead.
