Six calculators built around one question: how much can this trade lose, and what does it cost to hold? Every calculation runs in your browser and shows its formula.
Position Size Calculator — How many coins to buy or sell so that hitting your stop loses only the share of the account you chose to risk, fees included.
Liquidation Price Calculator — Where a USDT-margined perpetual position is liquidated, for isolated or cross margin, using the maintenance-margin formula exchanges publish. Fees and funding are not included, so the real liquidation price is slightly closer to entry.
Grid Bot Profit Calculator — The profit each completed buy-sell round earns after fees, and what the bot is worth if price falls to the lower bound or rises to the upper bound — the two cases a grid bot does not profit from.
DCA Average Price Calculator — Combines every buy into one average entry, break-even after fees, and profit or loss at the current price. The average is weighted by coins bought, so equal-sized buys at lower prices pull it down more than a simple average of prices.
Drawdown Recovery and Compounding Calculator — Losses and gains are not symmetric: a 50% drawdown needs a 100% gain to recover. See the recovery gain, the years to recover at an assumed return, and compound growth.
Funding Fee Calculator — Longs pay shorts when the funding rate is positive and receive when it is negative. Turn a rate and a holding period into money, per day and annualized, and as a share of your margin.
