How to calculate crypto profit
Enter how much you invested, the price you bought at, and the price you sold (or plan to sell) at. The calculator works out how many coins your investment bought, the value when you sell, and subtracts your original investment plus trading fees to show your net profit and return on investment (ROI).
The formulas
Coins = Invested ÷ Buy price · Sell value = Coins × Sell price · Net profit = Sell value − Invested − fees
Fees apply to both the buy and the sell. ROI = net profit ÷ invested × 100.
Worked example
Invest $1,000, buy at $30,000, sell at $45,000, with a 0.1% fee per trade:
- Coins bought: $1,000 ÷ $30,000 = 0.0333
- Sell value: 0.0333 × $45,000 = $1,500
- Fees (buy + sell): ≈ $2.50
- Net profit: ≈ $497.50 · ROI: ≈ +49.75%
Exit value vs net profit
The two figures answer different questions. Exit value is the cash you receive from selling, after the sell fee only. Net profit goes further — it also subtracts your original investment and the buy fee — so it's your true gain. Don't confuse the cash in hand with the actual profit.
Don't forget fees, tax, and risk
Exchange fees apply on both the buy and the sell and quietly eat into returns — this tool includes them. Crypto profits may also be taxable where you live; this calculator does not account for tax. Above all, crypto is volatile and high-risk: this is an estimate for general information, not financial advice.
Common mistakes to avoid
Quoting the raw price gain (here 50%) as your return while ignoring fees (the real ROI is 49.75%). Forgetting tax on gains. Treating exit value as profit. Investing more than you can afford to lose in a volatile asset.
Frequently asked questions
$1,000 at $30k buy, sold at $45k — what's the profit?
About $497.50 net (≈49.75% ROI) after a 0.1% fee on each trade.
Does it include trading fees?
Yes — applied to both the buy and the sell, so net profit reflects what you keep.
What's exit value vs net profit?
Exit value is cash after the sell fee; net profit also subtracts your investment and buy fee.
Can profit be negative?
Yes. If the sell price (after fees) is below your buy price, you have a loss.
Does it account for taxes?
No. Crypto gains may be taxable where you live; check local rules.
