Profit & Loss Calculator

What is the crypto profit and loss calculator?

The crypto profit and loss (P&L) calculator works out exactly how much you made or lost on a trade, including fees. Enter your buy price, sell price, the quantity of coins and any trading fee, and the tool returns your net profit or loss, your return on investment (ROI) as a percentage, and how your initial investment turned into final proceeds.

Knowing your true P&L matters because headline gains can be misleading once fees and position size are taken into account. A 10% price move on a small position is very different from the same move on a large one, and exchange fees on both the buy and the sell side quietly reduce your real return.

How profit and loss is calculated

The calculator uses a simple, transparent formula:

• Invested = buy price × quantity
• Proceeds = sell price × quantity
• Profit / Loss = proceeds − invested − total fees
• ROI = (profit ÷ invested) × 100

Fees are applied to both sides of the trade, because most exchanges charge when you buy and again when you sell.

A worked example

Imagine you buy 0.5 BTC at $60,000 and sell at $70,000, with a 0.2% fee per trade. You invested $30,000 and your proceeds are $35,000. Fees total roughly $130 (0.2% of each side). Your net profit is about $4,870, an ROI of roughly 16.2%. The calculator shows all of this instantly.

Tips for tracking your returns

• Always include fees — they compound across many trades.
• Compare ROI, not just dollar profit, to judge how efficient a trade was.
• Remember that selling may create a taxable event in many jurisdictions; keep records.
• Use the DCA calculator to plan regular buying, and the converter to value holdings.

Realised vs. unrealised profit and loss

There is a crucial difference between profit on paper and profit in the bank. Unrealised P&L is the gain or loss on a position you still hold — it rises and falls with the market and is not locked in. Realised P&L is what you actually keep once you sell. This calculator works out your realised result for a completed trade, which is the figure that matters for your returns and, in most places, your taxes.

How fees and spreads erode returns

Trading is rarely free. Exchanges charge a fee on both the buy and the sell, market makers earn the spread between bid and ask, and networks charge gas to move assets. Individually these look small — often a fraction of a percent — but across many trades they compound into a real drag on performance. That is why this calculator lets you include a fee percentage: a “winning” trade can become a loss once costs are counted.

Understanding your break-even price

Your break-even price is the price at which a sale would leave you exactly even after fees — neither profit nor loss. Knowing it helps you set realistic exit targets. As a rule of thumb, the higher your fees, the further above your entry price you must sell simply to get your money back.

Calculating ROI across multiple trades

Return on investment lets you compare trades of very different sizes on equal footing. A $100 profit on a $1,000 position (10% ROI) is a better use of capital than a $150 profit on a $5,000 position (3% ROI), even though the dollar figure is larger. When you make many trades, track ROI and your win rate together to see whether your strategy is genuinely working.

Profit, loss and tax

In most jurisdictions, selling crypto for a profit triggers a capital-gains tax event, and selling at a loss may be deductible against gains. Holding periods can change the rate. Keep records of your buy price, sell price, fees and dates for every trade — the figures this calculator produces are a useful starting point for that record, but always confirm the rules with a tax professional.

Common P&L mistakes

• Counting unrealised gains as if they were money you already have.
• Ignoring fees and the spread.
• Forgetting the tax owed on a profitable sale.
• Judging a trade only by dollar profit instead of ROI and risk taken.
