How to use the crypto profit calculator
- Pick the coin and your currency. The buy and sell prices start with a recent market snapshot; Get live price loads the latest price from CoinGecko.
- Enter the price you paid and the price you sold at (or want to sell at).
- Enter the money you invested, or switch to the number of coins if you know the exact amount.
- Set the trading fees of your exchange in percent. The result shows net profit, ROI, the fees you paid and your break-even price.
- Bought more than once? Open Average cost, add one row per buy and read your average entry price and profit at the current price.
How profit, ROI and break-even are calculated
The calculator treats each fee as a percentage of the trade value, paid in your currency. Most spot exchanges charge this way.
- Coins bought = investment ÷ (buy price × (1 + buy fee))
- You receive = coins × sell price × (1 − sell fee)
- Net profit = you receive − investment
- ROI = net profit ÷ investment × 100 %
- Break-even price = buy price × (1 + buy fee) ÷ (1 − sell fee)
- Average entry price = total cost of all buys ÷ total coins
Some exchanges take the buy fee in the coin instead, so you receive slightly fewer coins. With small fees the gap hardly matters: at 0.1 % it is about one cent per 10,000 invested.
Worked example: a Bitcoin trade with fees
You invest $2,000 in Bitcoin at $64,000. The exchange charges 0.1 % per trade. You get 2,000 ÷ (64,000 × 1.001) = 0.0312188 BTC.
Later you sell at $80,000. The trade value is $2,497.50, the 0.1 % sell fee is $2.50, so you receive $2,495.00.
Your net profit is $495.00 and your ROI is 24.75 %, although the price rose 25 %. The two fees cost $4.50 in total. Your break-even price was $64,128.13: below that price the trade loses money even though the price went up.
Averaging down: 물타기, ナンピン and DCA
Averaging down means buying more of a coin after its price has fallen, so your average entry price drops. Korean investors call it 물타기 ("adding water"), Japanese investors ナンピン. Buying at regular intervals no matter the price is called dollar-cost averaging (DCA).
Example: you hold 1 ETH bought at $3,000 and the price is now $2,400. To bring your average down to $2,700, you need (3,000 − 2,700 × 1) ÷ (2,700 − 2,400) = 1 ETH more, which costs $2,400. Your average is then $2,700 and the price only needs to recover to that level to break even.
Two limits always apply. The new average can get close to the new buy price but never reach it, and buying below your average can never raise it. The planner tells you when a target is out of reach. Averaging down also puts more money into a falling asset, so check that you still want to hold it.
How trading fees move your break-even price
Break-even price for a coin bought at 100, with the same fee on the buy and the sell:
| Fee per trade | Break-even price | Rise needed |
|---|---|---|
| 0 % | 100.00 | 0.00 % |
| 0.05 % | 100.10 | 0.10 % |
| 0.1 % | 100.20 | 0.20 % |
| 0.25 % | 100.50 | 0.50 % |
| 0.5 % | 101.01 | 1.01 % |
| 1 % | 102.02 | 2.02 % |
| 1.5 % | 103.05 | 3.05 % |
Spot fees depend on the exchange, your trading volume and the order type. As of 2026, Binance lists a 0.10 % base spot fee and Coinbase charges small accounts about 0.40 % (maker) to 0.60 % (taker). Instant "buy" buttons and card payments often cost 1 % or more, plus a spread.
Crypto profit and taxes
This calculator shows profit before tax. Tax rules for crypto differ a lot between countries and change often. Examples as of October 2026:
- Germany: gains on coins held for more than one year are tax-free for private investors; shorter-term gains are tax-free only if total private sales gains stay below €1,000 per year.
- United States: coins held for one year or less are taxed as short-term capital gains, longer holdings at lower long-term rates.
- Japan: crypto gains are currently taxed as miscellaneous income (雑所得) at progressive rates; a move to a flat 20 % separate tax is planned.
- South Korea: a 20 % tax (22 % with local tax) on yearly crypto gains above ₩2.5 million is scheduled to start in 2027.
Many countries also need a cost-basis method (average cost or FIFO) for partial sales. Check the rules of your tax authority or ask a tax adviser. Nothing on this page is tax or financial advice.
Good to know
- Use the price you actually paid, including any spread, not the chart price at the time.
- ROI is measured against the money you spent including fees, so it is always a little lower than the price change.
- Withdrawal and network fees are not included. Add them to your investment if you want them in the result.
- Your buys are saved only in this browser and never sent to a server.
