Leverage in forex lets you control a large currency position with a small deposit, called margin. A ratio of 30:1 means $1 of margin controls $30 of currency. It multiplies both your profit and your loss, and with some brokers you can lose more than you deposit.
Leverage lets you open a trade that is bigger than the money in your account. Your broker asks for a small deposit, called margin, and lends you the rest of the position. The ratio tells you how much bigger the trade can be. With 30:1 leverage, every $1 of margin controls $30 of currency.
The profit and the loss both come from the full position, not from your margin. That is the whole point, and the whole danger. A 1% move on a $30,000 position is $300, whether you put up $1,000 or $30,000.
Say you have $1,000 and your broker offers 30:1 on EUR/USD. You can open a position worth up to $30,000. You buy one mini lot, which is 10,000 euros, at 1.1000. The position is worth $11,000, so the broker holds $367 of your money as margin. The rest, $633, is free margin.
EUR/USD rises 50 pips to 1.1050. One pip on a mini lot is worth $1, so you have made $50, which is 5% of your account. If the price falls 50 pips instead, you lose $50. At 100:1 the same $1,000 could open ten mini lots, and the same 50 pips would make or lose $500. Half the account, on a move that happens most days.
Try your own numbers in our leverage calculator. It shows the margin you need for any position size and ratio, and how far the price can move before your account runs out.
Margin is the deposit the broker locks for each open trade. Free margin is what is left over for new trades or losses. Your margin level is your equity divided by the margin in use. When losses push it below the broker’s limit, you get a margin call. If it keeps falling, the broker closes your trades. That is the stop out.
In the EU, the UK and Australia the stop out for retail clients is set at 50% of the margin you need. Brokers regulated offshore choose their own level, and some let the account fall to 20% or lower before they act.
Yes, with some brokers. If a price gaps over the weekend or on a news release, the broker may not be able to close your trade before the account goes below zero. You then owe the broker the difference.
Negative balance protection stops that. It means your loss can never be bigger than your account. Regulators in the EU, the UK and Australia require it for retail clients. Many offshore brokers do not offer it, and a few offer it only on some accounts. Check the client agreement before you deposit.
Regulators cap retail leverage because losses grow with it. The caps below are the maximum a broker may offer to a retail client. Professional clients can get more, and offshore brokers are not bound by any of them.

Offshore brokers licensed in places such as Seychelles, Vanuatu, the Bahamas or Saint Vincent offer 500:1, 1000:1 or more. The number looks generous. It also means a 0.1% move can wipe out the margin on a trade.
The ratio your broker offers is the most you may use. It is not the amount you should use. What matters is how much of your account one trade puts at risk. A common rule is to risk no more than 1% or 2% of the account on a single trade, and to size the position from your stop loss, not from the leverage on offer. Our profit and loss calculator turns a stop distance into a position size.
Lower leverage also costs less. Brokers charge a swap for holding a leveraged position overnight, and the charge grows with the size of the position. Our fee calculator adds the spread, the commission and the swap for a trade you have in mind.
Prop firms sell challenges on simulated accounts, and most cap leverage at 30:1 to 100:1 on forex. The cap is in the firm’s rules, and breaking it can fail the challenge. Our prop firm profiles list each firm’s leverage and rules with the date we checked them.
Our beginner brokers list starts with regulated brokers that offer negative balance protection. The margin, micro lot and spread entries cover the other numbers you will meet on your first trade.
It means each $1 of margin controls $100 of currency. A $500 deposit can open a $50,000 position, and a 1% move against you loses $500, the whole deposit.
It is a tool that cuts the deposit you need. It does not change the size of the move you are trading. High leverage lets a small move close your account, which is why regulators cap it for retail clients.
With a broker that offers negative balance protection, no. Your loss stops at zero. Without it, a sharp gap can leave your account below zero and the broker can ask you to pay the difference.
Most beginners do best at 10:1 or less, even when the broker offers 30:1 or 500:1. Size each trade from the stop loss and risk 1% to 2% of the account, and the leverage takes care of itself.
They describe the same trade from two sides. Leverage is the ratio, such as 30:1. Margin is the deposit that ratio requires, such as 3.33% of the position. Our leverage calculator shows both.

Risk warning: trading forex and CFDs on margin carries a high risk of losing money. Most retail accounts lose money. Never trade with money you cannot afford to lose.
