Why use TraderCalcs.io
A calculator is only useful if you can tell what it did and what it ignored.
No signup, no email capture
Every calculator is fully usable the moment the page loads. Results are never held back behind a form.
Formulas shown in full
Each page documents the formula it uses, defines every term, and works through a numbered example with real figures.
Assumptions stated plainly
Where a calculation excludes spread, fees, slippage or tax, the page says so rather than letting you assume otherwise.
No figure you enter leaves your browser
Calculations run on your own device and no figure you enter is ever sent to a server. What the journal saves is saved there too, where only you can read it.

What these calculators are, and are not
Every tool on this site is a calculator: it takes the figures you enter and applies a documented formula to them. None of them provide trading signals, price predictions, investment recommendations or personalised financial advice, and none require an account. Position sizing tells you what size makes a stop-out cost 1% of your account — it has no view on whether the trade is a good idea.
Results depend entirely on your inputs. Where a calculation excludes costs that would apply in practice — spread, commission, slippage, platform fees or tax — the calculator page says so. Read the methodology for how the formulas are chosen and tested, and the disclaimer for the limits of what this site provides.
