# Quant Trading Calculators

> These are free, browser-only calculators for the risk and performance figures a systematic trader checks before deploying a strategy: position size, liquidation price, grid profit after fees, perpetual funding cost, Kelly fraction, risk of ruin, compound growth, and leveraged PnL. Every formula is printed on the page, nothing is sent to a server, and no account is required.

## Calculators

- [Position Size Calculator](https://qanterion.com/tools/position-size-calculator) — Size the trade from the stop, not from the balance. The leverage is an output, never an input.
- [Liquidation Price Calculator](https://qanterion.com/tools/liquidation-price-calculator) — Long and short liquidation levels for an isolated-margin position, with the distance in percent.
- [Crypto PnL Calculator](https://qanterion.com/tools/crypto-pnl-calculator) — Leveraged profit and loss for long and short, with return on equity and round-trip fees separated out.
- [Grid Trading Profit Calculator](https://qanterion.com/tools/grid-trading-profit-calculator) — Profit per completed grid net of round-trip fees, and the fee rate at which the configuration stops working.
- [Funding Rate Calculator](https://qanterion.com/tools/funding-rate-calculator) — Perpetual funding converted into cash per interval, per day, per holding period — and annualised.
- [Kelly Criterion Calculator](https://qanterion.com/tools/kelly-criterion-calculator) — The growth-optimal bet fraction, with the half and quarter positions most practitioners actually run.
- [Risk of Ruin Calculator](https://qanterion.com/tools/risk-of-ruin-calculator) — The chance a strategy hits your drawdown limit before its edge has time to show up.
- [Compound Growth Calculator](https://qanterion.com/tools/compound-growth-calculator) — Project account growth over time, with contributions reported separately from actual returns.
- [Sharpe Ratio & Max Drawdown Calculator](https://qanterion.com/tools/sharpe-ratio-calculator)
