Day Trading Tools & Calculators
Simple calculators that make core risk-management concepts easier to understand.
Turn risk concepts into numbers
Risk management is easier to understand when the arithmetic is visible. These calculators convert common day-trading concepts into simple, inspectable calculations: how position size changes with stop distance, how reward compares with planned risk, how much gain is required to recover a drawdown, and how win rate and average outcomes combine into expectancy.
Use the tools as learning aids alongside the underlying reference pages. The inputs are hypothetical; real trading can include slippage, gaps, commissions, borrowing costs, partial fills, tax consequences and other factors not represented here.
Four risk-management calculators
Position Size Calculator
Estimate a share quantity from account size, chosen risk percentage, entry price and stop price.
Open calculator →CalculatorRisk/Reward Calculator
Compare the planned downside from entry to stop with the planned upside from entry to target.
Open calculator →CalculatorDrawdown Recovery Calculator
See why the percentage gain required to recover grows faster as drawdowns deepen.
Open calculator →CalculatorTrading Expectancy Calculator
Combine win rate, average win and average loss into an average expected outcome per trade.
Open calculator →What these tools deliberately do not do
They do not tell you what risk level to choose, where a stop should be placed, which strategy to trade, or whether a setup has an edge. Those are separate decisions. The calculators simply make the arithmetic transparent once assumptions have been supplied.
