Calculators on This Site
Win Rate Calculator — Calculate your win rate from your trade history.
Risk of Ruin Simulator — Monte Carlo simulation: what % of the time does this strategy blow through your ruin threshold?
Compound Growth Calculator — Project expected account growth by compounding your average win % and loss % per trade (expected value, not guaranteed).
DCA Average Price Calculator — Add each buy to find your weighted average entry price and total position size.
Risk/Reward Ratio Calculator — See your risk-reward ratio and the minimum win rate you need to break even.
Kelly Criterion Calculator — Find the mathematically optimal % of capital to invest per trade, based on your edge.
Liquidation Price Calculator — Estimate where isolated-margin futures positions get liquidated (approximation — exact formulas vary by exchange).
Position Size Calculator — Find the correct position size so a stop-out only costs you the % of account you choose to risk. (Note: required margin rates and calculation methods vary by exchange and product — this is an approximation.)
Drawdown Recovery Calculator — See how much gain you need just to get back to even after a loss — the deeper the drawdown, the more disproportionately hard it is to recover.
Required Win Rate Calculator — Enter your starting capital, target capital, and expected number of trades to find the win rate you'll need. Risk/reward ratio and target expectancy are optional — leave them blank and they'll be set automatically.
Options Breakeven Calculator — Enter a strike price and premium to find the breakeven point and expiration payoff of an options position.
Leverage P&L Simulator — See how the same price move produces very different returns at different leverage levels, from just an entry and target price (simplified linear model — excludes funding and fees).
