Margin Calculator (Trading) computes the margin required to open a leveraged position and the resulting leverage — a risk-management tool for traders, and entirely distinct from the business profit-margin calculator that shares the name.
Trading margin is the deposit needed to control a larger leveraged position, with the broker funding the rest. Margin and leverage are two sides of one coin: a 10% margin is 10:1 leverage, a 2% margin is 50:1 — the smaller the margin, the bigger the position your capital controls, and the bigger the risk.
That risk is the heart of the matter. Leverage magnifies losses exactly as it magnifies gains, so at 50:1 a 2% adverse move erases your entire deposit — which is why over-leverage is the classic way traders blow up accounts. The margin figure can lull you into forgetting how little movement it takes to be in trouble.
Trading well within your available margin avoids margin calls, where losses below the maintenance level force you to add funds or have positions liquidated — often at the worst time. It's an analysis aid, not trading advice, and runs in your browser. For business pricing margin, use the separate Margin Calculator; pair this with the Position Size and Risk-Reward calculators.
Don't confuse trading margin with profit margin — for pricing, use the separate Margin Calculator
Higher leverage = smaller margin but proportionally bigger risk; a 2% move at 50:1 wipes your deposit
