Free trading calculators

Consistent traders are not the ones who are right most often. They are the ones who size and manage risk the same way on every trade. These free calculators handle the math that keeps a single losing trade from doing lasting damage, so you can focus on reading the market instead of second-guessing your numbers.

Each tool answers one question, and they fall into a few groups. Risk and sizing: how large a position can be before one loss costs more than a fixed share of the account, and what one pip or one point is worth once it is on. Performance math: the win rate a ratio needs to break even, the expectancy a record actually carries, the gain that recovers a drawdown, and what compounding does to a balance over time. Forex: pip value and lot size in your account currency, including JPY pairs. Prop-firm rules: what a published profit target and loss limit mathematically require at your risk per trade. Setup quality: a rules-based grade and cost basis for the position you already hold. Every tool runs entirely in your browser, needs no signup, and is educational only, not financial advice.
