Forex Leverage Explained: 1:30 vs 1:500 and What You Actually Need

Leverage is the ratio between your money and the position you control. At 1:30, every dollar of deposit lets you open thirty dollars of exposure. It is not technically a loan — nobody transfers you money; the broker simply ring-fences part of your balance as margin.

How margin is calculated

Margin = volume × price / leverage.

One lot of EUR/USD at 1.08 is a $108,000 position.

• At 1:30, margin is $3,600.
• At 1:100, $1,080.
• At 1:500, $216.

Note what does not change: the position is identical in all three cases. One pip is worth $10 regardless of leverage. Leverage alters neither profit nor loss — only how much free cash is left in the account.

So why is 1:500 dangerous

Because high leverage removes a natural brake. At 1:30 on a $500 account you physically cannot open more than 0.13 lots. At 1:500 you can open a lot and a half, and a 30-pip move against you wipes the account out.

The European caps arrived after regulators' own data showed 74–89% of retail CFD accounts losing money. Leverage was not the only cause, but it was the most visible one.

What you actually need

If you size positions from your stop rather than from margin, you rarely need more than 1:100. High leverage makes sense in one scenario: when you deliberately keep only a slice of your capital at the broker and the rest outside. Then 1:500 compensates for the small deposit while risk is still measured against total capital.
