Crypto Profit Calculator

The calculator turns your dollars into coins at the buy price, then values those coins at the sell price:

• Position size: your investment ÷ buy price (minus the entry fee, if you set one).
• Profit / loss: exit value after fees minus what you put in.
• ROI: profit as a percentage of your investment, so trades of different sizes are comparable.
• Break-even price: the sell price where you walk away with exactly what you started with, after both fees. Anything above it is profit.

The quick-exit chips (+25%, +50%, 2×, 5×, 10×) set the sell price relative to your entry so you can sanity-check a target in one tap. Before you lean on a 10× target, type that price into the crypto market cap calculator to see the market cap it would give the coin. Sub-cent coins keep full precision: the math is the same for $64,000 Bitcoin and $0.00001 PEPE.

The calculator starts from the dollars you put in, not from a number of coins. It takes three steps, and you can check each one by hand. In the formulas, the fee is your rate per side written as a decimal, so 0.5% is 0.005:

• Coins bought = investment × (1 − fee) ÷ buy price. The entry fee comes out of your investment first, and the rest buys the coins.
• Exit value = coins × sell price × (1 − fee). The exit fee comes out of what the sale brings in.
• Profit = exit value − investment. A negative result is a loss.

Leave the fee field blank and both fee steps drop out. What remains is the short version of any crypto profit or gains calculation: profit = (sell price − buy price) × coins.

ROI = profit ÷ investment × 100. A $388.03 profit on an $800 investment is 388.03 ÷ 800 × 100 = 48.5%. Because it is a percentage, ROI lets you compare a $500 trade with a $50,000 one. The entry fee is already inside your investment, so the calculator divides by every dollar that left your account, not by the smaller amount that reached the coin.

With leverage switched on, the same row is labelled return on margin and divides by the margin you put up, not by the full position.

Break-even sell price = buy price ÷ (1 − fee)². With no fee it is your buy price. With a fee it sits above your buy price by slightly more than twice the fee rate, because you pay once going in and once coming out:

Sell above the break-even price and the trade made money. Sell below it and the trade lost money, even when the sell price is higher than the buy price.

A winning trade with no fee. You put $20,000 into Bitcoin at $40,000 and sell at $60,000, with the fee field left blank. Coins bought: $20,000 ÷ $40,000 = 0.5 BTC. Exit value: 0.5 × $60,000 = $30,000. Profit: $30,000 − $20,000 = $10,000. ROI: $10,000 ÷ $20,000 × 100 = 50%. Break-even with no fee is the buy price, $40,000.

A winning trade with a fee. You put $800 into Polkadot at $4.00 and sell at $6.00, with an example fee of 0.5% per side. Entry fee: 0.5% of $800 = $4.00, so $796 buys 796 ÷ 4 = 199 DOT. That is 199 coins, not 200, because the fee came out first. Sale: 199 × $6.00 = $1,194.00. Exit fee: 0.5% of $1,194.00 = $5.97. Exit value: $1,194.00 − $5.97 = $1,188.03. Profit: $1,188.03 − $800 = $388.03. ROI: $388.03 ÷ $800 × 100 = 48.5%. Fees paid: $4.00 + $5.97 = $9.97. Break-even: $4.00 ÷ 0.995² = $4.04. The calculator rounds dollar amounts of $1,000 or more to the whole dollar, so its exit value row reads $1,188.

A losing trade with a fee. You put $1,000 into Solana at $250 and sell at $200, with the same 0.5% fee per side. Entry fee: 0.5% of $1,000 = $5.00, so $995 buys 995 ÷ 250 = 3.98 SOL. Sale: 3.98 × $200 = $796.00. Exit fee: 0.5% of $796.00 = $3.98. Exit value: $796.00 − $3.98 = $792.02. Loss: $792.02 − $1,000 = −$207.98. ROI: −$207.98 ÷ $1,000 × 100 = −20.8%. The price fell 20%, and the two fees, $8.98 in total, turned that into a 20.8% loss. Break-even was $250 ÷ 0.995² = $252.52.

The table below runs the same profit and return math across a few coins and sizes (fees omitted to keep the arithmetic clear), including a losing trade so the sign is obvious:

Searches for a crypto gains calculator, a crypto earnings calculator, a bitcoin earnings calculator, a crypto return calculator or a cryptocurrency investment calculator all land on the same maths. Those words describe one thing from different angles:

• Gains is the dollar difference between what you sold for and what you paid: the profit figure.
• Return / ROI is that same gain as a percentage of your cost, so a $500 win on $2,000 reads as a 25% return.
• Earnings is the informal word for realised profit once you have actually sold.
• Profitability asks whether the position is above or below break-even right now, fees included.

This page answers all of them at once. Enter an investment, a buy price and a sell price and you get the gain in dollars, the return as a percentage, and the break-even that decides whether the position is profitable yet.

The calculator is not Bitcoin-only. Pick any of 200+ assets from the coin selector and the buy and sell fields prefill with that coin's live price, so a bitcoin profit calculation and a Polkadot (DOT) or BitTorrent (BTT) profit calculation run through the identical formula. It scales cleanly across price ranges:

• Large caps: Bitcoin (BTC) and Ethereum (ETH), where a small percentage move on a five-figure price is still real money.
• Mid caps: coins like Polkadot (DOT) or Solana (SOL), priced in single or double digits, where the DOT profit calculator use case fits.
• Sub-cent tokens: BitTorrent (BTT) and similar, where prices run to many decimal places. The BTT profit calculator keeps full precision so a fraction-of-a-cent entry and exit still resolve to exact profit.

For any coin the selector does not list, type the buy and sell prices in by hand. The profit, ROI and break-even come out the same way.

Set the leverage control above 1× and this becomes a crypto profit calculator with leverage: pick 2× to 100×, choose long or short, and the position is sized off your margin, the money you actually put up. A $1,000 margin at 10× controls a $10,000 position, and every price move hits that full $10,000, in both directions:

• Position size = margin × leverage. The fees apply to the whole position, not just your margin, so they scale up with the leverage too.
• Profit / loss: the price move times the full position, measured against your margin. A 5% move at 10× is a 50% gain or loss on your money.
• Liquidation price ≈ entry × (1 − 1/leverage) for a long, entry × (1 + 1/leverage) for a short. It's the price where the loss equals your margin and the exchange closes the position.

Worked example: 10× long on ETH. A $1,000 margin at 10× opens a $10,000 position, 4 ETH at a $2,500 entry. ETH rises 10% to $2,750 and the position gains 4 × $250 = $1,000, a 100% return on margin. The same 10% move down wipes the margin entirely, which is what the liquidation estimate says: $2,500 × (1 − 1/10) = $2,250.

Be clear-eyed about the odds. Regulators who audit retail broker data consistently find that a large majority of leveraged retail accounts lose money, and higher leverage brings liquidation closer: at 100×, a 1% move against you ends the trade. The calculator's liquidation price is an estimate that ignores maintenance margin and funding fees, so real exchanges close positions slightly earlier than it shows.

The result is what one trade made or lost at the prices and the fee you typed. Six things are outside it:

• Taxes. The profit shown is before tax. Tax rules differ from country to country, and the calculator does not apply any of them.
• Price slippage. The calculator assumes you bought and sold at exactly the prices you typed. An order can fill at a slightly different price from the one on screen. To include that, type the prices your orders actually filled at.
• Withdrawal and network fees. A fee for moving coins is charged per transfer, not as a percentage of the trade, so the fee field cannot hold it. Subtract it from the profit figure yourself.
• A different fee on each side. The fee field applies one rate to both the buy and the sell. If your two rates differ, enter their average. With 0.1% on one side and 0.6% on the other, entering 0.35% puts the result within one cent for every $1,000 sold.
• More than one buy. The calculator takes a single buy price. If you bought the same coin several times at different prices, work out your average cost first with the crypto DCA calculator, then enter that average as the buy price here and your total spend as the investment.
• Funding on leveraged positions. With leverage on, the calculator does not add the funding payments a futures position pays or receives while it stays open.

A profit calculator tells you what a move was worth. The harder question is whether you can call the move before it happens, and that's measurable. On BitPredict you call any coin up or down over 24 hours, the call locks with a timestamp, and your accuracy is scored on a public leaderboard. It's the same instinct this calculator prices out, minus the money at stake, because it's paper-trading-style and free.
