Free trader tools
Free Trading Calculators
8 calculators for forex, gold, indices and crypto. All of them run in your browser, none of them ask for an email, and nothing you type is stored or sent anywhere.
Before the trade
The three that decide what you're actually about to do. Size comes from your stop, not your habit; pip value turns pips into money; margin tells you whether the broker will even let you open it.
Judging an edge
Numbers you can't eyeball. A win rate means nothing without the reward:risk beside it, and a backtest result means nothing without knowing how much of it could be luck.
Planning and timing
What a fixed return actually compounds to, and when the markets you trade are genuinely active in your own timezone.
Why these eight, and not forty
Most "free forex tools" pages are a wall of forty calculators, thirty-five of which are the same multiplication with a different label. These are the eight that answer a question a trader actually gets wrong.
Three of them cover the same trade from different angles, and it is worth being precise about the difference because conflating them is expensive. The position size calculator answers how big should this be — an output of your stop distance and your risk budget. The pip calculator answers what is this worth per pip — the conversion from price movement into money, which changes by instrument and is routinely got wrong on JPY pairs, gold and crypto. The margin calculator answers what does the broker hold, and how levered am I really — a question about the contract, not the risk. Margin is not risk. A trade risks what its stop costs, whatever the leverage.
A calculator is not a backtest
Every tool here operates on one trade, or on inputs you supply. None of them can tell you whether the setup you are sizing is worth taking — that answer only comes from a sample.
Which is the honest limit of a calculator page. You can compute a perfect position size for a strategy with no edge and lose money with excellent precision. The numbers that decide whether you make money — win rate, average R, worst losing streak, whether the result is distinguishable from luck — come from replaying real history and logging what happened. That is what the rest of this site is for, and how to backtest a trading strategy is the place to start.
Free, and free in the way that matters
No signup, no email capture, no usage limit, no trial. Each calculator runs entirely client-side, so nothing you enter — balance, position size, account details — leaves your browser. Every tool also has an embed snippet at the bottom of its page if you want to drop it into your own site or trading community.
The calculators size the trade. The backtest tells you to take it.
