Net PnL = gross price move minus entry fees, exit fees, and funding. Position size is margin × leverage, so both profits and losses are amplified. Maker and taker fees should be modeled separately because official Coinbase Advanced fee guidance treats liquidity-providing and liquidity-taking orders differently.
The calculator uses a simplified leverage estimate: entry × (1 − 1/leverage) for longs and entry × (1 + 1/leverage) for shorts. Real venues can liquidate earlier because of maintenance margin, mark price rules, and funding. The CFTC virtual currency advisory warns that leverage amplifies risk in virtual currency derivatives.
Break-even is the exit price where gross PnL exactly covers entry fee, exit fee, and funding. For a long: BE = (position size + entry fee + funding) / (coins × (1 − taker fee)). For a short, the sign flips and the divisor becomes (1 + taker fee).
Many traders start with at least 1:2, meaning the take-profit distance is twice the stop-loss distance. It is still only a planning rule: FINRA notes that crypto assets can be extremely volatile and may lose value quickly.
Perpetual futures funding can turn a good-looking trade into a weaker net result when a position is held for several days. Funding is exchange-specific, so use your live rate; this model treats it as a daily cost on position size. For background, Binance Academy explains how funding payments move between long and short traders.
Crypto assets can move fast, and leverage turns small price changes into large equity swings. This calculator combines position size, fees, funding, break-even, stop-loss risk, and a simplified liquidation estimate before you commit capital.
"A trade is not planned until fees, funding, stop-loss loss, and liquidation distance are visible on the same screen."
Separate Fees
Use maker and taker rates from your exchange tier. Coinbase documents why the two order types can have different costs.
Respect Liquidation
Treat liquidation as a danger zone, not an exact promise. The CFTC warns that leverage can amplify both gains and losses.
Price Funding
Funding is a carrying cost on perpetual futures. Binance Academy explains why long and short traders exchange funding payments.
