Crypto Profit Calculator

An estimate, not financial advice. Figures are indicative, and the assumptions behind them are stated on the tool itself. Tax rules, rates and fees vary by country and change over time — check against your provider or a qualified adviser before acting on a number.

Overview

What is a Crypto Profit Calculator?

A Crypto Profit Calculator works out the gain or loss on a trade. Profit = (sell price − buy price) × quantity − fees, and ROI = profit ÷ your total cost. Enter a current price instead of a sell price to see unrealized profit. Fees and tax reduce your real return.

This calculator gives you a clear, fee-aware picture of a cryptocurrency trade. Enter your buy price, your sell price (or the current price for a position you still hold), the quantity, and your trading fees, and it works out your profit or loss, your ROI percentage, and your break-even price.

The core formula is simple: profit = (sell − buy) × quantity − total fees, and ROI = profit ÷ total cost (what you paid, including the buy fee). If you prefer, enter an investment amount instead of a quantity and the tool derives the coins from your buy price. It also shows your total invested, total returned, and fees paid, and the break-even price — the sell price you'd need just to cover your buy cost plus fees. Using a current price gives unrealized profit (on paper, still changing); using an actual sell price gives realized profit.

How to calculate your crypto profit

Step 1: Enter your buy price. The price you paid per coin (or an investment amount)

Enter your buy price. The price you paid per coin (or an investment amount).

Enter your sell or current price. A sell price for realized P&L, or the current price for unrealized.

Step 3: Enter the quantity. How many coins or tokens (or let the amount derive it)

Enter the quantity. How many coins or tokens (or let the amount derive it).

Step 4: Add your fees. Buy and sell fees, as a percentage or flat amount

Add your fees. Buy and sell fees, as a percentage or flat amount.

Step 5: Read profit, ROI, and break-even. With totals and fees paid

Copy any figure.

When a crypto profit calculator helps

Now the honesty, which matters a lot with crypto. This is a calculator, not advice, and not a live price feed — it does arithmetic on the numbers you type, it doesn't fetch prices, predict them, or suggest you buy or sell anything. Crypto is highly volatile: a gain on screen can vanish quickly, and past performance tells you nothing about the future. Fees genuinely eat into returns — exchange fees, spreads, and network/gas fees can be significant, so include what you can. And this tool doesn't calculate tax: in most countries crypto profits are taxable (usually capital gains, sometimes income), which further reduces your net — estimate that with the Capital Gains Tax Calculator using your own rate.

For averaging multiple buys into a cost basis first, see the Stock Average Calculator (the maths works for crypto too). Everything runs privately in your browser — no account, no upload.

After a trade. See realized profit and ROI net of fees.
Holding a position. Check unrealized P&L at the current price.
Break-even. Know the price you need just to cover cost and fees.
Planning a sell. Use a target price to size a desired profit.
Any coin. The same maths works for any token.

Realistic example. Buy 0.5 BTC at $40,000 ($20,000) with a 0.2% fee, sell at $50,000 ($25,000) with a 0.2% fee: profit ≈ (50,000 − 40,000) × 0.5 − ~$90 fees = about $4,910, an ROI of roughly 24.5%.

Advanced tip. Check the break-even price before selling — with fees on both sides, you need a bit more than your buy price just to get even.

Common mistake to avoid. Don't ignore fees and tax. Both reduce your real return, sometimes noticeably on frequent trades.

What to keep in mind

Crypto is highly volatile. On-screen gains can disappear fast; past performance means nothing for the future.
Not advice, and no live prices. It does arithmetic on your inputs — it doesn't fetch prices, predict them, or tell you to trade.
Fees reduce returns. Exchange, spread, and network/gas fees add up — include what you can.
Tax not included. Crypto profits are usually taxable; estimate separately with your own rate.
Private. All math runs on your device — nothing is uploaded, no account needed.

Frequently Asked Questions

How do I calculate crypto profit?

Subtract your buy price from your sell price, multiply by the quantity, then subtract fees: profit = (sell − buy) × quantity − total fees. For example, 0.5 BTC bought at $40,000 and sold at $50,000, minus ~$90 of fees, is about $4,910. Enter your prices, quantity, and fees and the tool does this, showing profit or loss net of costs.

---

What is my ROI on a crypto trade?

ROI (return on investment) is your profit divided by what you put in: ROI = profit ÷ total cost, where cost is your buy price × quantity plus the buy fee. A $4,910 profit on a ~$20,040 cost is about 24.5%. ROI puts the gain in percentage terms so you can compare trades of different sizes. The tool shows it alongside the dollar profit.

---

How do fees affect my crypto profit?

They reduce it, sometimes more than people expect. Every buy and sell usually carries an exchange fee, and moving crypto can incur network (gas) fees, plus the spread between buy and sell prices. On frequent or small trades these add up and can turn a small gain into a loss. Enter your buy and sell fees so the profit and ROI reflect what you actually keep.

---

What is my break-even price?

Your break-even price is the sell price at which your profit is exactly zero — it has to cover your buy cost plus the fees on both sides, so it's a little above your buy price. The tool calculates it for you. Knowing it before you sell stops you from exiting at what looks like a small gain but is really a break-even or loss after fees.

---

What's the difference between realized and unrealized profit?

Realized profit is locked in — you've actually sold, so the gain or loss is final. Unrealized profit is on paper: you still hold the coins, and you're valuing them at the current price, which keeps changing. Enter a sell price for realized profit, or a current price for unrealized. Crypto's volatility means unrealized gains can swing hard before you ever sell.

---

Can I enter an investment amount instead of quantity?

Yes. If you know how much money you put in rather than the exact number of coins, enter the investment amount and the buy price, and the tool derives the quantity (amount ÷ buy price). This is handy for the common "if I put $1,000 into this coin" question. The profit, ROI, and break-even then follow from there.

---

Does this calculate tax on my crypto gains?

No. It shows your pre-tax profit and ROI. In most countries crypto profits are taxable — often as capital gains, sometimes as income — and the rate depends on your country, holding period, and total income. That tax reduces your net return. Estimate it separately with the Capital Gains Tax Calculator using your own rate, and check your local rules.

---

Does this use live prices?

No. This is a calculator, not a price tracker — it uses the buy and sell (or current) prices you enter, not a live feed. That keeps it private and offline, and means you're in control of the figures. Look up the current price from an exchange or data site and type it in for an unrealized-profit estimate.

---

Can I use this for any coin or token?

Yes. The profit and ROI maths is identical for any cryptocurrency — Bitcoin, Ethereum, or any altcoin or token. Just enter that coin's buy and sell prices, your quantity, and the fees. The same applies to fractions of a coin. It also works for other assets bought and sold at a price, though it's designed with crypto trading in mind.

---

Is crypto a good investment — should I buy?

This tool can't answer that, and it doesn't try to. It only does arithmetic on trades you enter; it doesn't predict prices or recommend buying, selling, or holding. Crypto is highly volatile and can lose value rapidly, and whether it suits you depends on your goals and risk tolerance. That's a decision for you, ideally with a qualified professional — not a calculator.

---

Is this financial advice?

No. This calculator computes profit, ROI, and break-even from the numbers you enter — it's an estimate, not financial or tax advice, and not a signal to trade. Results ignore tax and depend entirely on your inputs. For investment decisions, consult a qualified financial professional and consider crypto's high volatility.

---

Is my data uploaded, and does it work offline?

No upload, and yes it works offline. Every calculation runs entirely in your browser, so your trade details are never sent to a server, there's no account, and no tracking. Once the page has loaded it keeps working with no connection — good for checking a trade privately without linking an exchange.
