Calculate your cryptocurrency profit, loss, ROI, and break-even price. Works for Bitcoin, Ethereum, and every other coin.
Using this calculator is straightforward. You need three numbers: the price you bought at (or plan to buy at), the price you sold at (or plan to sell at), and how much money you put in. The calculator does the rest.
Let's say you bought Bitcoin at $30,000 and sold at $45,000 with a $1,000 investment. You'd have purchased 0.0333 BTC, and your total at the sell price would be $1,500. That's a $500 profit and a 50% ROI.
ROI stands for Return on Investment. It tells you the percentage gain or loss relative to your initial investment. A positive ROI means you made money. A negative ROI means you lost money. It's one of the most basic but important metrics any investor should track.
The formula is simple: ROI = ((Sell Price - Buy Price) / Buy Price) x 100. If you bought ETH at $2,000 and it's now at $2,400, your ROI is 20%. If it drops to $1,600, your ROI is -20%.
Your break-even price is the price at which you neither make money nor lose money. For a simple spot trade without fees, the break-even price is your buy price. If you factor in trading fees, the break-even price is slightly higher since you need the asset to appreciate enough to cover the cost of buying and selling.
Knowing your break-even helps you set realistic targets. There's no point setting a sell order below your break-even, because you'd still be losing money once you account for fees.
Most people check the price of their coins and think they know if they're up or down. But without calculating exact numbers, you're guessing. Here's why tracking matters:
The biggest mistake is forgetting about fees. Exchange fees, network fees, and spread all eat into your profits. If you're trading on a platform that charges 0.5% per trade, that's 1% round-trip (buy + sell). On a $10,000 position, that's $100 in fees alone.
Another common error is comparing unrealized and realized gains. Unrealized gains are profits on paper. You haven't sold yet, so you haven't locked them in. Markets move fast, and unrealized gains can evaporate. Only count it as profit once you've actually sold.
Finally, don't forget about the time value of money. A 10% return in one week is very different from a 10% return over two years. Annualizing your returns gives you a much clearer picture of performance.
