Profit & loss, break-even price, and DCA average cost.
The Crypto Calculator covers three essential calculations: profit & loss for any trade, dollar-cost averaging (DCA) to find your average buy price, and break-even price. Works for Bitcoin, Ethereum and any cryptocurrency.
Three tabs cover the most common questions. P&L: enter buy price, sell price, amount of coin and any fees โ the calculator returns dollar profit or loss and percent return. DCA: list each buy you've made (amount in dollars, price at the time) and the tool computes your weighted average entry price and total coin held โ vital for knowing your real cost basis after multiple buys. Break-even: enter your average price and total fees; the tool returns the exact price you need to sell at to walk away even. Switch tabs freely; values don't bleed between them.
DCA average is a weighted average: (ฮฃ dollars spent) รท (ฮฃ coins received), not a simple mean of prices. Two $1,000 buys at $50,000 and $30,000 give an average of $37,500, not $40,000 โ because the lower-priced buy bought more coin. Profit/loss factors in fees on both sides: (sell ร amount ร (1 โ fee)) โ (buy ร amount ร (1 + fee)). Break-even works backwards from average price: BE = avg / (1 โ total_fee_pct). Fees of 0.1% per side seem trivial but matter on high-frequency trading.
Working out your real cost basis after dollar-cost averaging into Bitcoin over a year, deciding whether to take a partial profit at break-even after a long drawdown, comparing two exit strategies side by side, or stress-testing how a 1% trading fee eats returns over many trades.
