Crypto profit calculator
This crypto profit calculator works out the result of a simple spot trade: you spend a dollar amount at one price and sell the coins later at another. It takes a percentage fee on the purchase and again on the sale, which is how most exchanges charge.
The formula
Proceeds = coins × sell price × (1 − fee)
Profit or loss = proceeds − amount invested
Break-even sell price = buy price ÷ (1 − fee)², the price at which proceeds exactly equal what you put in.
Worked example
Illustrative figures: you invest $500 when Bitcoin is $50,000, with a 0.2% fee per trade.
- Coins bought = 500 × 0.998 ÷ 50,000 = 0.00998 BTC.
- You sell at $55,000. Proceeds = 0.00998 × 55,000 × 0.998 = $547.80.
- Profit = 547.80 − 500 = $47.80, or 9.56% on the amount invested, although the price rose 10%.
- If you sold at $45,000 instead, proceeds would be $448.20 and the loss $51.80, more than the 10% price fall.
Break-even here is 50,000 ÷ 0.998² ≈ $50,200.60: the price has to rise about 0.4% before you are even.
Reading the crypto profit calculator result
The main figure is your profit or loss in dollars after both fees. It does not include network fees for moving coins, withdrawal charges, the spread on "instant buy" screens or any tax due where you live, so treat it as a best case. The same maths works for any coin priced in dollars or in USDT.
For small, frequent trades, fees add up quickly; trading fees explained shows the full list. To understand what you are buying in the first place, start with how crypto works or the Bitcoin lesson.
