Why these are free and ungated
A calculator that asks for an email before showing a number is not a tool, it is a form.
Each of these does one calculation completely, in the open, with the formula printed on the page. You can check the arithmetic by hand — and you should, at least once, because a sizing calculator you have not verified is a number you are trusting blindly with your account.
They are also honest about their limits. None of them converts currencies at an invented exchange rate, none includes spread or commission, and each says so on its own page rather than quietly rolling an assumption into the answer.
What a calculator cannot do is tell you whether you followed it. That needs the trades you actually took, which is what MetaTradee is for.
