Leverage & Margin Calculator
Leverage & Margin Calculator
This forex leverage calculator shows the exact margin your broker locks up when you open a position, on currency pairs, gold, indices and crypto. Choose the instrument, the lot size and the leverage your account runs on, and you see the money required before you commit it rather than afterwards.
What are Leverage & Margin in Trading?
Leverage allows a trader to control a larger position using less money (margin) and therefore greatly amplifies both profits and losses. Leveraged trading is also called margin trading.
Margin is the capital a trader must put up to open a new position. It is not a fee or cost and is freed up again once the trade is closed. Its purpose is to protect the broker from losses. When losses cause a trader’s margin to fall below a pre-defined stop out percentage, one, or all open positions, are automatically closed by the broker. A margin call warning from the broker may or may not precede such liquidation.
How Does Leverage Work
Instrument: In this field traders can select from several forex crosses, including major and minor pairs, from the most popular cryptocurrencies (ADA, BTC, DOGE, ETH, LTC, Stellar, Ripple, etc), popular indices and commodities, such as Gold, Silver and Oil. For our example, we will choose the EUR/USD.
Deposit currency: Margin values differ for forex pairs, and other financial instruments, and are subject to the current market quote. By selecting the deposit currency, it will be possible to accurately display the margin required to open a position, for the selected instrument, in the choosen currency (from AUD to ZAR). We will choose GBP as our deposit currency, for this example.
Leverage: In this field traders just need to input a leverage ratio. This could be the current leverage offered by the broker, or any other ratio, from as little as 1:1 to 6000:1 to simulate the amount of margin used to open a position. For our example, we will select a leverage of 30:1.
Lots (trade size): Just enter the lot size. Remember, in forex 1 lot is 100,000 currency units per lot, but units per lot vary for non-forex pairs. So, in this field there’s also the option of switching between lots and units for the calculations. For our example, we will use a trade size of 0.10.
Next, we click the “Calculate” button.
The results: Using all the data above the Leverage & Margin Calculator tell us that to open a trade position, long or short, of a 0.10 lot EUR/USD, with 30:1 leverage, and with the current EUR/GBP exchange rate of 0.90367, we would need a margin of 301,22 GBP.
What the forex leverage calculator actually measures
First of all, margin is not a fee and it is not a cost. It is a deposit that your broker freezes while the position stays open, and you get every unit of it back the moment you close. The forex leverage calculator answers one question: how much of your balance disappears into that freezer.
In fact, the arithmetic itself is short. One standard lot of EUR/USD is 100,000 units, so at a price of 1.0850 the position is worth 108,500 dollars. At 1:100 leverage the broker asks for one hundredth of that, which is 1,085 dollars. At 1:500 the same trade needs only 217 dollars, while a European account capped at 1:30 has to find 3,617 dollars for exactly the same trade.
Forex leverage calculator table: margin per standard lot
These figures use one standard lot of EUR/USD at 1.0850, so scale them down for smaller lots. Half a lot needs half the margin, and 0.01 lots need one hundredth of it.
| Leverage | Margin for 1 lot EUR/USD | Typical account |
|---|---|---|
| 1:30 | 3,616.67 | Europe and the UK, retail |
| 1:100 | 1,085.00 | Most international brokers |
| 1:200 | 542.50 | Common offshore setting |
| 1:500 | 217.00 | Aggressive offshore accounts |
| 1:1000 | 108.50 | Small accounts, high risk |
Metals and indices follow the same logic with different contract sizes. One lot of gold is 100 ounces, for instance, so at 3,650 dollars an ounce the position is worth 365,000 dollars and at 1:100 it locks 3,650 dollars of margin.
Leverage is not risk, and the forex leverage calculator shows why
Above all, this is the point that costs most beginners their first account. Indeed, leverage does not decide how much you lose, your stop loss and your lot size do. A trader on 1:500 who risks 1 percent per trade is far safer than a trader on 1:30 who throws three lots at a 100 pip stop.
What leverage really changes is your margin level, that is equity divided by used margin, times one hundred. When that number falls to the broker stop out level, usually somewhere between 20 and 50 percent, the platform closes your trades for you and you have no say in it. Consequently, high leverage is dangerous only because it lets you open positions that are far too large for the balance behind them.
Fix the risk first with the lot size calculator, then come back here to confirm the margin fits comfortably inside your equity.
How to use the forex leverage calculator in four fields
- Instrument. Majors, minors, exotics, indices, gold, silver, oil and the main cryptocurrencies are all in the list, and each one, of course, carries its own contract size.
- Deposit currency. The result converts into your account currency at the live rate, so a euro account and a dollar account get different numbers for the same trade.
- Leverage. Use the setting your broker really gave you, not the headline on the website, since many brokers cut leverage on gold, indices and crypto.
- Lot size. Enter the volume you intend to open. If the margin comes back close to your free equity, the trade is simply too big.
As a working rule, keep total used margin under a quarter of your equity. That way a normal drawdown never turns into a margin call, and you can check how deep that drawdown might go with the drawdown calculator.
Forex leverage calculator questions traders ask
Does higher leverage cost more? No, because your broker returns the margin when the trade closes. Besides, the spread, the swap and the commission stay the same whatever leverage you use.
Why did my required margin change overnight? Brokers often raise margin requirements before the weekend, around major news and on volatile instruments such as gold or crypto. Therefore, always confirm the current setting rather than assuming last week’s number.
What happens when the margin level drops? First you get a margin call warning, usually at 100 percent, and then the stop out closes positions automatically. Because the platform starts with the biggest loser, you rarely lose the trade you would have chosen yourself.
How much leverage do I actually need? Generally, for swing trading on a funded account, 1:30 is plenty. For intraday work on gold with tight stops, 1:100 to 1:200 gives room without tempting you, especially if you already let an indicator such as Deadbolt define the levels for you.
