Crypto Profit Calculator

The Real Cost of a Crypto Trade

Most traders only calculate gross profit and forget the fees. On a $10,000 round trip at 0.1% maker + 0.1% taker, that's $20 lost to fees — small on one trade, but it adds up: a trader doing 500 round trips per year on $10k positions pays $10,000 in fees alone. Multiply by tax and a big chunk of your gross profit disappears.

ROI then divides Net PnL by the original buy value, giving you the true return on capital — not the inflated gross number.

How Crypto Capital Gains Tax Works

Every country treats crypto differently, but most apply some form of capital gains tax to disposals (selling, swapping, spending). The two big variables:

• Holding period: Many countries (US, AU, DE) offer reduced or zero rates for assets held longer than 1 year.
• Income bracket: Rates often scale with your overall income. A higher earner pays more on the same gain.

Our jurisdiction selector applies mid-bracket assumptions to give you a quick ballpark. For an actual tax return use specialized software (Koinly, CoinTracker, TokenTax) or a qualified accountant.

5 Costly Mistakes Crypto Traders Make on Taxes

1. Forgetting crypto-to-crypto swaps are taxable. Trading BTC for ETH triggers capital gains in the US, UK, AU, and most other places — not just selling to fiat.
2. Not tracking cost basis. Without accurate buy prices and fees, you cannot prove your gain. The default in many tax authorities is to assume your basis was zero — taxing the entire sale value.
3. Ignoring tax-loss harvesting. Realized losses can offset realized gains. Strategically selling losers at year-end is one of the cheapest tax optimizations available.
4. Treating staking and airdrops as untaxed. Most jurisdictions tax these as income at fair market value when received.
5. Underestimating short-term tax drag. Day-trading crypto at 22–37% short-term rates can wipe out otherwise winning strategies. Sometimes holding 13 months is the highest-ROI decision you make.
