Profit, ROI, and what the fees quietly took.
Crypto gains look bigger in your head than in your account — buy fees, sell fees, and spreads all shave the outcome. This calculator computes your true net profit: how many coins your investment bought, what they are worth at the exit price, what fees consumed, and your real return on investment. Use it before selling, or to plan entry and exit targets.
People use this before selling (to see the real profit after fees), when planning exit targets, and at tax time to reconcile what the exchange says against what they actually made. Fees quietly change the answer more than most traders expect.
In most jurisdictions, yes — selling, swapping, or spending crypto at a gain is typically a taxable event (capital gains in the US, UK, and many others). This calculator shows pre-tax profit; keep records of every trade.
Exchanges usually display unrealized P&L at the current mid-price and may exclude withdrawal or network fees. Enter your actual filled buy price and a realistic sell price here for the number that matters.
Anyone quoting a fixed number is selling something. Historically crypto has produced both triple-digit years and 70%+ drawdowns. Plan exits with this calculator instead of hoping.
