A set of free calculators for the arithmetic that decides whether a strategy survives: position size, pip value, risk-to-reward, margin and profit or loss projection.
Enter your account balance, the percentage you are willing to risk and the distance to your stop-loss, and the calculator returns the position size that keeps the loss at exactly that percentage if the stop is hit. This is the single most useful number in trading and the one most often estimated rather than calculated.
Pip value for any pair and lot size, risk-to-reward ratio from entry, stop and target, margin requirement at a given leverage, and a profit and loss projection across price scenarios.
All tools are free, require no account, and run entirely in your browser.
Two traders can take exactly the same setups and end the year in completely different places purely because of how they sized. Risking a fixed small percentage per trade means a losing streak is survivable and recoverable; risking whatever felt right at the time means a single bad run can remove the account regardless of how good the analysis was. Calculating the size rather than estimating it is the whole difference, and it takes a few seconds.
Risk-to-reward works the same way. A strategy that wins four trades in ten is profitable at three-to-one and loses steadily at one-to-one, so knowing the ratio before you enter tells you whether the trade is worth taking at all. The calculator gives you that number from your entry, stop and target so the decision is made before the position exists rather than justified afterwards.
Margin and pip-value calculations exist for the same reason: they replace assumptions with figures. Nothing here is proprietary or predictive — it is standard arithmetic, provided free so there is no reason to skip it.
Yes, all of them, and no account is required.
Divide the cash amount you are willing to lose by the distance between your entry and your stop-loss, adjusted for the pip or tick value of the instrument. The position size calculator does this for you from your balance, risk percentage and stop distance.
