Free tools
Free trading calculators
Five free tools for the numbers you need before a trade: your risk/reward ratio, your position size, your average cost per share, your pip value, and a graded read on the setup itself. Everything runs in your browser, with no signup and nothing sent to a server.
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. Position sizing: deciding how many shares or units to trade so a loss only ever costs a fixed percentage of your account. Pair it with a risk/reward ratio check to see whether a setup is worth taking and what win rate you would need to break even. Use the stock average calculator to track your cost basis across multiple buys and your unrealized profit or loss, and the pip value calculator to size forex positions correctly in your account currency. When the plan is written down, the trade setup grader scores it against a published rules table and hands back a letter grade you can review later. Every tool runs entirely in your browser, needs no signup, and is educational only, not financial advice.
