  2. How it works

Free online calculators for traders: lot size, pip value, margin, profit, risk/reward, drawdown, compound interest and martingale. They run right in your browser, with no sign-up, on desktop and mobile.

Why traders need calculators

Most accounts are blown not by a bad strategy but by the wrong position size. A calculator shows in a second how much you lose at the stop and make at the target — before you press Buy. Start with the lot size calculator: it sizes the position from your balance, risk percentage and stop loss.

How it works

  • Each calculator remembers your last inputs in your browser.
  • Share a calculation: “Copy link to this calculation” saves every field in the page URL.
  • Under each calculator you will find strategies with clear stop-loss rules that it fits.
  • The same lot calculation runs inside MT4 and MT5 in our free EA, S4U.PRO Trade Panel — get it from @s4u_panel_bot.

New calculators are added here as they are ready. Follow our Telegram channel @S4Ueng to catch them.
