Each one uses standard industry formulas and states its assumptions on the page: how fees are charged, what a contract is worth, which margin rules apply. Results update as you type, and the link in your address bar stores your inputs, so you can bookmark a setup or send it to someone.
They do arithmetic, not forecasts. A calculator can tell you what a price move would be worth; it can't tell you whether it will happen.
For education and planning only, not investment advice. Results are calculated from the numbers you enter and the assumptions stated on this page.
