Calculate crypto profit/loss and ROI from buy price, sell price, fees, and quantity.
Table of Contents
Every crypto trader eventually asks the same deceptively simple question: "Did I actually make money on that trade?" The gap between the answer you think is true and the answer that is true is almost always explained by two things — quantity math mistakes and trading fees. The Crypto Profit Calculator closes that gap by computing your net profit, loss, ROI, and breakeven price from the exact numbers you enter.
Unlike exchange dashboards that blur average entry prices across months of orders, this calculator gives you a clean, single-trade view. You enter a buy price, a sell price, a quantity (or a dollar investment amount), and the fee percentages your exchange actually charges. The tool then shows your true net result, broken down into cost basis, total fees, and net proceeds.
Best of all, every calculation runs entirely in your browser. No account, no API keys, no data leaving your device — which matters when you are plugging in real position sizes you would rather not share with yet another web service.
Why Traders Need a Crypto Profit Calculator
- Fees eat more than you think. A 0.1% taker fee sounds tiny, but it applies on both the buy and the sell side. On a round-trip trade you lose roughly 0.2% before price even moves — on a $10,000 position that is $20 gone before you start.
- ROI is the only honest comparison metric. "I made $500" means nothing without knowing how much was invested. The calculator reports ROI as a percentage so you can compare a BTC swing trade against an ETH position or a stock trade on equal footing.
- Partial exits are confusing. If you bought 1.2 ETH and sold 0.75 ETH, what did that specific exit earn? By entering the exact quantity sold, you get the P&L for that slice instead of a vague portfolio feeling.
- Exchange interfaces hide the math. Most exchanges show you "realized PnL" with their own fee tiers, rebates, and rounding baked in. Recomputing it yourself with explicit fee inputs keeps the math transparent and auditable.
- Breakeven planning prevents nasty surprises. Knowing the exact sell price at which you stop losing money (fees included) turns "I hope it goes up" into a concrete level you can set a limit order at.
- Privacy by design. Because everything is computed client-side, you can model large hypothetical positions without ever sending a byte to a server.
Key Features
| Feature | What it does |
|---|---|
| Buy / Sell price inputs | Enter entry and exit prices in USD for any asset |
| Quantity or Investment mode | Specify coin quantity directly, or enter a dollar amount and let the tool derive it |
| Buy Fee (%) and Sell Fee (%) | Model real exchange fees per side — e.g. 0.1 for Binance, 0.5 for Coinbase |
| Profit / Loss result | Large color-coded display: green for profit, red for loss |
| Breakdown cards | Total Cost (cost basis + fees), Net Proceeds (gross − fees), Price Change %, Total Fees, effective Quantity |
| Report export | Copy or download a formatted text summary of the trade |
Two details make daily use smoother. First, the investment-amount mode means you can work from the dollar figure you actually wired to the exchange ("I put in $2,000") rather than reverse-engineering a quantity. Second, the fee fields accept any percentage, so the same tool works for a 0.02% maker rebate setup or a 1.5% convenience-app spread — the math does not care which venue you use.
How to Use the Crypto Profit Calculator
- Open the Crypto Profit Calculator — no signup or wallet connection required.
- Enter your Buy Price and Sell Price in USD. These can be historical fills or a hypothetical exit you are evaluating.
- Enter your position size: either the coin Quantity (e.g. 0.5 BTC) or the Investment Amount in dollars — whichever you know offhand.
- Fill in the Trading Fees section with your exchange's buy-side and sell-side percentages. Binance spot users typically enter 0.1 on both; Coinbase Advanced users might enter 0.6.
- Read the result panel: net Profit or Loss, ROI percentage, price change, total fees paid, and the full cost breakdown. Use Copy or Download to save the summary for your trading journal.
The Math Behind Your P&L
The calculator follows the standard realized-P&L model that any accountant would recognize, applied per trade:
- Cost basis = buy price × quantity
- Total cost = cost basis + (cost basis × buy fee %)
- Gross proceeds = sell price × quantity
- Net proceeds = gross proceeds − (gross proceeds × sell fee %)
- Net profit = net proceeds − total cost
- ROI = net profit ÷ total cost × 100
Notice that fees enter the formula twice, once on each side, and that ROI divides by the fee-inclusive cost. That is why a trade that "looks" like +25% on paper often lands closer to +24.7% in reality.
Worked example. Suppose you bought 0.5 BTC at $40,000 and sold at $50,000, with 0.1% fees on both sides (a typical Binance spot taker round trip):
- Cost basis: 0.5 × $40,000 = $20,000
- Buy fee: 0.1% × $20,000 = $20 → total cost $20,020
- Gross proceeds: 0.5 × $50,000 = $25,000
- Sell fee: 0.1% × $25,000 = $25 → net proceeds $24,975
- Net profit: $24,975 − $20,020 = $4,955
- ROI: $4,955 ÷ $20,020 = 24.75% (versus the naive 25% price change)
Breakeven. Because of the two fees, your breakeven sell price is slightly above your buy price — approximately buy × (1 + buy fee) ÷ (1 − sell fee), which for this trade is about $40,080. Below that price, the trade is a loss no matter how good it felt.
Practical Use Cases
Post-trade review for your journal
You closed a SOL position last week and the exchange app says "realized PnL +$312," but your journal wants clean numbers. Enter your actual fills and fees into the calculator, download the text report, and paste it into your log. Now your weekly review compares consistently computed trades instead of mixed vendor figures.
Planning a take-profit level
Before entering a trade, flip the tool into planning mode: put in your intended entry, your position size, and your exchange fees, then try candidate sell prices. Watch how the ROI readout changes from 1× to 2× to 3× your risk. When you know that $47,300 is where you clear a 15% net ROI after fees, setting the limit order becomes mechanical.
Comparing exchange fee tiers
Is paying for a lower fee tier worth it? Model the same $20,000 round trip at 0.1% versus 0.075% (BNB discount) versus 0.6% (Coinbase one-taker pricing). The fee card makes the dollar difference obvious across a year of trades, and the answer is often "the discount pays for itself within weeks."
Reviewing a dollar-cost-average position
You accumulated ETH in eight small buys at different prices. Compute the volume-weighted average entry by hand (or a spreadsheet), then feed that average as the Buy Price and your total quantity into the calculator to see what a sell at today's price would actually net you after fees.
Best Practices
- Use your real fee tier, not the headline one. Check whether you actually pay 0.1% or enjoy a maker discount — a wrong fee assumption compounds across every logged trade.
- Separate each exit into its own calculation. If you sold a position in three tranches, run three calculations; averaging tranches hides which exits created or destroyed value.
- Record the calculation date and prices in your journal. The downloadable report is only as useful as the context you keep around it.
- Model fees before entering, not after exiting. The cheapest time to discover a fee problem is before the trade exists.
- Double-check quantity precision. Altcoin positions often involve quantities like 1,483.72 tokens — a dropped digit turns a winner into a loser on paper.
- Keep sensitive position sizes client-side. This calculator never uploads your inputs, so keep it that way: avoid pasting reports with sizes into public forums.

Frequently Asked Questions
Q: Does the calculator support cryptocurrencies other than Bitcoin?
A: Yes. The math is asset-agnostic — enter any buy price, sell price, and quantity, whether the asset is BTC, ETH, SOL, or a micro-cap token. Prices are entered in USD, but you can treat the currency as any fiat unit since the percentages work identically.
Q: How do I enter my exchange's fees?
A: Type the percentage number directly, without the percent sign — for example, enter 0.1 for Binance spot's 0.1% taker fee or 0.5 for a Coinbase tier. Buy-side and sell-side fees are entered separately, so asymmetric fee schedules are fully supported.
Q: Can I calculate profit from a dollar amount instead of coin quantity?
A: Yes. Use the optional Investment Amount field and the tool derives the quantity for you. This is convenient when you remember "I put in $2,000" more clearly than the exact coin count.
Q: Is my trade data sent anywhere?
A: No. All computation happens in your browser with JavaScript — there are no API calls, no analytics on your inputs, and no account. You can even use the tool offline once the page has loaded.
Happy trading!
